A developer can build and develop GIMP using Windows. One reason to do so is to fix any GIMP bugs specific to the Windows platform.  However, there is already a package of GIMP for Windows (at: [http://gimp-win.sourceforge.net/ GIMP Windows installers by Jernej Simončič.]). A GIMP debugger or developer would still need to submit patches to the GIMP development team.

The main GIMP building instructions are at [[Hacking:Building]]. This page is for Windows-specific additions to that page.  
  
Note: the instructions are not always kept up to date; check on irc.gnome.org #gimp first if you are not sure. The primary development platform is the Debian Testing GNU/Linux distribution, so the very latest code from GIT might not always build on other platforms.

As 6/1/2019 you can build only the Gimp 2.10 branch due missing dependences on master branch
+
Msys2 is a POSIX environment with basically everything you would find on a Linux system (shell, package manager, GCC…). It allows to use POSIX tools to build Windows softwares.
  
=== Setting up a devel environment ===

=== Setting up the environment ===
  
First, '''follow the installation instructions''' for msys2 available at [https://msys2.github.io/ msys2.github.io].
+
First, '''follow the installation instructions''' for msys2 available at [https://msys2.github.io msys2.github.io].
  
Make sure to follow the post-installation instructions on that page to update the msys2, mingw64, mingw32 systems appropriately.
+
To open a terminal, you need to execute <code>msys2.exe</code> or <code>mingw64.exe</code>
This includes:
+
  
* Updating pacman and the package database:
+
Update the system :
<nowiki>pacman -Sy pacman</nowiki>
+
  pacman -Syyuu
* If needed, close MSYS2 and run it again (note: the installed .bat files don't appear to work on win10, launch it directly from the install location, ie: c:\msys2\msys2.exe).<br/>Update the package database and core system packages:
+
  <nowiki>pacman -Syu</nowiki>
+
  
''If an error is thrown'' about <code>incompatible versions of the cygwin DLL</code> and the following warnings are shown:
+
If the shell tells you to close the terminal, close MSYS2 and run it again. That is a normal procedure.
  
warning: terminate MSYS2 without returning to shell and check for updates again
+
=== Install the dependencies ===
warning: for example close your terminal window instead of calling exit
+
  
Then follow the instructions and close the terminal window (it may warn you of running processes, choose "OK" to close it anyway).
+
==== If you want to build gimp 2.10 ====
  
Re-open MSYS2 from the install directory by running <code>msys2_shell.cmd</code>, and re-run the update command <code>pacman -Syu</code>.

Once everything is updated, exit out of MSYS2.
 
  
The shortcut for running mingw64, called "MinGW-w64 Win64 Shell" won't work after the update.

==== If you want to build gimp master ====
  
Run <code>mingw64.exe</code> directly from the install directory (by default: <code>c:\msys64\mingw64.exe</code> or <code>c:\msys32\mingw32.exe</code>).

Next, edit your .bash_profile, and add these lines:
 
 
<nowiki>
 
export PREFIX=`realpath ~/prefix`
 
export PATH="$PREFIX/bin:$PATH"
 
export PKG_CONFIG_PATH="$PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH"
 
export PKG_CONFIG_PATH="$PREFIX/share/pkgconfig:$PKG_CONFIG_PATH"
 
export LD_LIBRARY_PATH="$PREFIX/lib:$LD_LIBRARY_PATH"
 
export XDG_DATA_DIRS="$XDG_DATA_DIRS:$PREFIX/share:/usr/local/share/:/usr/share/"</nowiki>
 
 
If you have Windows 64 bit add
 
 
<nowiki>
 
export ACLOCAL_FLAGS="-I/c/msys64/mingw64/share/aclocal"</nowiki>
 
 
If you like, you can also add this to .bash_profile:
 
<nowiki>
 
export MAKEFLAGS=-j4</nowiki>
 
This will cause make to do a multi-core build, using the number of cores specified after the -j option.
 
 
Note: if you're comfortable in the terminal, you can simply use vi/vim: <code>vim .bash_profile</code>.<br/>
 
Otherwise the file can be found in the msys2 install directory, by default: <code>C:\msys64\home\{USERNAME}\.bash_profile</code>
 
 
Now, reload your .bash_profile:

. .bash_profile</nowiki>

Libmypaint is a relatively new dependency for git-master.
+
You can now just follow the instruction on the main page [[Hacking:Building]]. Just be careful of the following changes :
  
  <nowiki>
+
* If you are on Windows 64bits, you may need to add an environment variable for Autotools :
git clone https://github.com/mypaint/libmypaint.git
+
  export ACLOCAL_FLAGS="-I/c/msys64/mingw64/share/aclocal"
cd libmypaint
+
git checkout tags/v1.3.0 #Use tag 1.3.0
+
./autogen.sh
+
./configure --prefix=$PREFIX
+
make
+
make install
+
cd ..</nowiki>
+
  
Mypaint-brushes:
+
You can add all the environment variable on C:\msys64_or_msys32\home\{USERNAME}\.bash_profile then run
  
  <nowiki>
+
  . .bash_profile
git clone https://github.com/mypaint/mypaint-brushes
+
cd mypaint-brushes
+
git checkout v1.3.x
+
./autogen.sh
+
./configure --prefix=$PREFIX
+
make
+
make install
+
cd ..</nowiki>
+
  
Now, prepare to build babl and gegl
 
  
<nowiki>
+
* Use Libmypaint 1.3.0 (FIXME : should be updated ?). Download the 1.3.0 source tarball, or checkout the correct tag in <code>git</code> :
mkdir -p build/babl
+
git checkout tags/v1.3.0 #Use tag 1.3.0
mkdir build/gegl</nowiki>
+
  
 +
* Use Mypaint-brushes 1.3.x. Download the 1.3.0 source tarball, or checkout the correct tag in <code>git</code> :
 +
git checkout v1.3.x
  
<nowiki>
+
* Disable docs for Babl : <code>-Dwith-docs=false</code> while calling Meson.
git clone https://gitlab.gnome.org/GNOME/babl.git
+
cd build/babl
+
SRCDIR=../../babl
+
meson -Dprefix=$PREFIX $SRCDIR -D with-docs=false
+
ninja
+
ninja install
+
cd ../..</nowiki>
+
  
Next, gegl from git.
+
* Disable docs for Gegl : <code>-Ddocs=false</code> while calling Meson.
  
<nowiki>
 
git clone https://gitlab.gnome.org/GNOME/gegl.git
 
cd build/gegl
 
SRCDIR=../../gegl
 
./autogen.sh --prefix=$PREFIX --enable-gtk-doc-html=no --disable-docs
 
make
 
make install
 
cd ..</nowiki>
 
  
and then gimp If you don't need the docs to be built, bypass them by adding <code>--disable-docs</code> to autogen:
+
You may want to disable the docs while building Gimp :  
  
<nowiki>
+
* Meson build : <code>-Dgtk-doc=false -Dgtk-doc-app=false</code>
git clone https://gitlab.gnome.org/GNOME/gimp.git
+
* Autotools build : <code>--disable-docs</code>
cd gimp
+
./autogen.sh --prefix=$PREFIX --disable-gtk-doc --with-gimpdir=GIMP/git-master --with-javascript=force --with-lua=force
+
make
+
make install
+
cd ..</nowiki>
+

<nowiki>
 
git clone https://gitlab.gnome.org/GNOME/gimp.git
 
 
with
 
 
git clone -b gimp-2-10 --single-branch https://gitlab.gnome.org/GNOME/gimp.git</nowiki>
 
 
 
==== To Do ====
 
Check the inclusion of python into the build.
 
 
=== Running GIMP ===
 
 
If everything worked up until now, you should be able to run GIMP like this:
 
 
for gimp 2.10
 
<nowiki>
 
gimp-2.10</nowiki>
 
 
and for master
 
 
<nowiki>
 
gimp-2.99</nowiki>
 
 
== Building GIMP natively under Windows using MinGW ==
 
 
While the MSYS2 instructions above are the recommended method for compiling gimp on windows, you may find some of these older resources for compiling with plain mingw useful.
 
MinGW is an open source Linux environment available on the Windows platform.
 
 
The following articles discuss building GIMP on and for the Windows platform using MinGW:

=== Create a separate environment prefix ===
 
 
You obviously don't want to mix your Windows binaries with your normal distribution (and also you want to avoid ever having to use ''root'').
 
For instance you can choose:
 
 
<code>
 
$ mkdir $HOME/w64/
 
 
$ cd $HOME/w64
 
</code>
 
  
 
=== Install mingw-w64 ===

The original [http://www.mingw.org/wiki/LinuxCrossMinGW MinGW] projects can only compile for Windows 32 bits. Hence this procedure relies on the newer [http://mingw-w64.sourceforge.net/ MinGW-w64] project.
+
If your distribution provides the <code>mingw-w64</code> tools, you may install them with your package manager.
 
+
If your distribution provides the mingw-w64 tools, you may install them with your package manager. Otherwise you can download directly on SourceForge the last [http://sourceforge.net/apps/trac/mingw-w64/wiki/download%20filename%20structure daily snapshot] from the project.
+
 
+
For instance if you are on Linux 64 bits and want to compile for Windows 64 bits, you should download '''mingw-w64-bin_x86_64-linux_20121031.tar.bz2'''.
+
Note that you can install alongside '''mingw-w32-bin_x86_64-linux_20121031.tar.bz2''' if you want to be able to cross-compile for Windows 32 bits as well.
+
  
<code>$ tar xjf mingw-w64-bin_x86_64-linux_20121031.tar.bz2</code>
+
Otherwise, download directly the last release [https://sourceforge.net/projects/mingw-w64/files/mingw-w64/mingw-w64-release on Sourceforge].
  
This will extract all the cross-compiling tools and generate a prefix tree inside your $HOME/w64 directory.
+
The archive contains a prefix tree, that you can consider as read-only (just like your linux system).

TODO : Make a proper dependency list.
  
 
=== Set your cross-compiling environment ===
 
=== Set your cross-compiling environment ===
  
1. Choose your target:
+
Define the environment variables as described in [[Hacking:Building]]. You may also need to reset pkg-config:
 
+
export PKG_CONFIG_LIBDIR=
For building Windows 32 bits executables:
+
 
+
<code>$ export HOST=i686-w64-mingw32</code>
+
 
+
For building Windows 64 bits executables:
+
 
+
<code>$ export HOST=x86_64-w64-mingw32</code>
+
 
+
 
+
2. Create a dependencies prefix:
+
 
+
<code>$ export DEP_PREFIX=$HOME/w64/usr/$HOST/sys-root/mingw</code>
+
 
+
 
+
3. Create an installation prefix, that you chose earlier:
+
 
+
<code>$ export PREFIX=$HOME/w64</code>
+
 
+
 
+
4. You don't want any library linked from your normal Linux environment, so let's reset pkg-config:
+
 
+
<code>$ export PKG_CONFIG_LIBDIR=</code>
+
 
+
<code>$ export PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig:$DEP_PREFIX/lib/pkgconfig</code>
+
 
+
<code>$ export LD_LIBRARY_PATH=$PREFIX/lib:$DEP_PREFIX/lib</code>
+
 
+
 
+
5. Used tools though may still use the old path as well, but preferably the downloaded MinGW.
+
 
+
NOTE: This step is useless if you installed MinGW-w64 from your distribution.
+
 
+
<code>$ export PATH=$PREFIX/bin:$DEP_PREFIX/bin:$PATH</code>
+
 
+
 
+
6. Let GEGLs and GIMPs configure scripts find JPEG, MNG and EXIF2 support. If you set this, you won't need the ''--without-libjpeg'' option in GIMPs configure step:
+
 
+
<code>$ export C_INCLUDE_PATH=$DEP_PREFIX/include</code>
+
 
+
 
+
7. Finally let's add some compilation flags:
+
 
+
<code>$ export ACLOCAL_FLAGS="-I $DEP_PREFIX/share/aclocal"</code>
+
 
+
<code>$ export CFLAGS="-I$DEP_PREFIX/include -I$PREFIX/include"</code>
+
 
+
<code>$ export CPATH="$DEP_PREFIX/include:$PREFIX/include"</code>
+
 
+
<code>$ export LDFLAGS="-L$DEP_PREFIX/lib -L$PREFIX/lib"</code>
+
 
+
NOTE: If you installed MinGW-w64 from your distribution, the ''"-L$DEP_PREFIX/lib"'' or ''"-I$DEP_PREFIX/include"'' will have to be replaced by your
+
distribution default profile, likely respectively ''"-L/usr/x86_64-w64-mingw32/lib"'' and ''"-I/usr/x86_64-w64-mingw32/include"''.
+
 
+
 
+
8. You will probably want to save these values if you have to cross-compile again for Windows.
+
The best is to save them in a file "env-64.sh" (and env-32.sh), that you can ''source'' at anytime.
+
  
 
=== Build BABL ===
 
=== Build BABL ===

git clone git://git.gnome.org/babl
You can use released versions if they have a version big enough. As the time of writing this, GIMP from git requires BABL and GEGL from git as well.

== Cross-Compiling GIMP under UNIX using crossroad ==
+
== Troubleshooting ==
  
This is basically the same procedure as "[[#Cross Compiling GIMP under UNIX using MinGW-w64]]", but wrapped in a tool called `crossroad`, which makes it easier because there is no "magic" to remember (like the host and target syntaxes, etc.) and also because the dependency handling is done through an installer tool, similar to usual package managers.
+
==== Running gimp-2.x.exe on Windows fails. Error messages about a missing entry point in libglib-2.0-0.dll or a missing bzip2.dll are shown.====
Check this [https://mail.gnome.org/archives/gimp-developer-list/2013-October/msg00108.html email] where the procedure is explained for a full GIMP build with crossroad, and install [https://pypi.python.org/pypi/crossroad crossroad] from pypi.
+
'''Cause:'''
 +
 
 +
The missing dll files are in the MinGW binary folder, which is separate from the GIMP folders.
 +
 
 +
'''Solution:'''
 +
 
 +
To export the GIMP build to Windows properly, use the following steps:
 +
 
 +
1. On Windows create a folder for the GIMP build, like GIMP-Master.
 +
 
 +
2. Copy all files from $HOME/w64/$HOST/sys-root/mingw to the newly created folder.
 +
 
 +
3. Copy all files from your $PREFIX folder to the newly created folder. There are duplicate subfolders, for instance bin, share etc., in both directories. If your filemanager asks you to overwrite them, then confirm.
 +
 
 +
It's important to keep this order to ensure you overwrite older BABL and GEGL from the grab-stuff.sh script by the newer ones from your build.
 +
 
 +
At the end you have merged your MinGW installation and the GIMP build to a running GIMP on Windows build.
 +
(It also contains the unnecessary MinGW binaries, which are not needed anymore to run GIMP. But for testing purposes you have a running GIMP installation.)
 +
 
 +
==== Some fonts, like Sans, are shown improperly ====
 +
See also [https://bugzilla.gnome.org/show_bug.cgi?id=688593 the Bugzilla report].
 +
 
 +
'''Cause:'''
 +
 
 +
The fontconfig package installation writes absolute paths of the building system to fonts.conf and conf.d/*.conf. When GIMP is installed on the Windows target system, these absolute paths become invalid.
 +
 
 +
'''Solution:'''
 +
 
 +
The bug should be reported to the Fontconfig developers. Meanwhile do on the Windows target system:
 +
 
 +
1. Close GIMP.
 +
 
 +
2. Edit the file ''<GIMP installation folder>\etc\fonts\fonts.conf'':
 +
 
 +
Replace the line <code><include ignore_missing="yes">$a_directory/conf.d</include></code> by <code><include ignore_missing="yes">..\..\share\fontconfig\conf.avail</include></code>
 +
 
 +
3. Restart GIMP.

Latest revision as of 21:12, 29 December 2019

The main GIMP building instructions are at Hacking:Building. This page is for Windows-specific additions to that page.

Note: the instructions are not always kept up to date. The primary development platform is the Debian Testing GNU/Linux distribution, so the very latest code from Git might not always build on other platforms.

Building GIMP natively under Windows using MSYS2

Msys2 is a POSIX environment with basically everything you would find on a Linux system (shell, package manager, GCC…). It allows to use POSIX tools to build Windows softwares.

Setting up the environment

First, follow the installation instructions for msys2 available at msys2.github.io.

To open a terminal, you need to execute msys2.exe or mingw64.exe

Update the system :

pacman -Syyuu

If the shell tells you to close the terminal, close MSYS2 and run it again. That is a normal procedure.

Install the dependencies

If you want to build gimp 2.10

If you have Windows 64bits:

pacman -S \
    base-devel \
    git \
    mingw-w64-x86_64-toolchain \
    mingw-w64-x86_64-asciidoc \
    mingw-w64-x86_64-drmingw \
    mingw-w64-x86_64-gexiv2 \
    mingw-w64-x86_64-ghostscript \
    mingw-w64-x86_64-glib-networking \

Simply hit enter at the prompts for which packages to install (default=all). This step will download a ton of packages, and may take a while.

Building the software

You can now just follow the instruction on the main page Hacking:Building. Just be careful of the following changes :

  • If you are on Windows 64bits, you may need to add an environment variable for Autotools :
export ACLOCAL_FLAGS="-I/c/msys64/mingw64/share/aclocal"

You can add all the environment variable on C:\msys64_or_msys32\home\{USERNAME}\.bash_profile then run

. .bash_profile


  • Use Libmypaint 1.3.0 (FIXME : should be updated ?). Download the 1.3.0 source tarball, or checkout the correct tag in git :
git checkout tags/v1.3.0 #Use tag 1.3.0
  • Use Mypaint-brushes 1.3.x. Download the 1.3.0 source tarball, or checkout the correct tag in git :
git checkout v1.3.x
  • Disable docs for Babl : -Dwith-docs=false while calling Meson.
  • Disable docs for Gegl : -Ddocs=false while calling Meson.


You may want to disable the docs while building Gimp :

  • Meson build : -Dgtk-doc=false -Dgtk-doc-app=false
  • Autotools build : --disable-docs

Cross-Compiling GIMP under UNIX using crossroad

A tool named crossroad has been developed to cross-build for Windows under Linux (it was even originally started to crossbuild GIMP specifically).

See the tutorial explaining how to build GIMP with it.

Condensed, here is the process:

crossroad w64 gimp-build

crossroad install \
    glib2-devel \
    libexiv2-devel \
    json-glib-devel \
    libjpeg8-devel \
    libpng-devel \
    cairo-devel \
    libtiff-devel \
    librsvg-2-2 \
    librsvg-devel \
    pango-devel \
    libwebp5 \
    libwebp-devel \
    libjasper-devel \
    gdk-pixbuf-devel \
    libSDL-devel \
    libjson-c2 \
    libjson-c-devel \

    libwmf-devel \
    libgexiv2-devel headers

wget http://prdownloads.sourceforge.net/libpng/libpng-1.6.29.tar.xz
tar xf libpng-1.6.29.tar.xz
pushd libpng-1.6.29
crossroad configure
make && make install
popd

git clone git://git.gnome.org/babl
pushd babl
crossroad configure
make && make install
popd

git clone git://git.gnome.org/gegl
pushd gegl
crossroad configure
make && make install
popd

git clone https://github.com/mypaint/libmypaint.git
cd libmypaint
crossroad configure
make && make install
popd

git clone git://git.gnome.org/gimp
crossroad configure --disable-python
make && make install
popd

Check out the full tutorial for more details.

Note: this is basically the same thing as the Mingw64 cross build, simply crossroad wraps all the complicated parts!

Cross-Compiling GIMP under Linux using MinGW-w64

Experience shows that working with the MinGW environment on a Linux machine provides a much faster compilation, and you are still able to compile for any Windows target (32 and 64 bits).

NOTE: the following procedure should be distribution-independent and does not rely on your package management system, even though it uses some OpenSuse packages. It would probably work on OSX or any other UNIX as well (add a note on the list below if you know this procedure works on another OS).

Has been known to work on at least: Linux Mint 15, Ubuntu 12.04LST and Mageia 2 distributions.

Source of the original procedure from an email by Victor Oliveira.

Install mingw-w64

This procedure relies on the newer MinGW-w64 project.

If your distribution provides the mingw-w64 tools, you may install them with your package manager.

Otherwise, download directly the last release on Sourceforge.

The archive contains a prefix tree, that you can consider as read-only (just like your linux system).

Install GIMP Dependencies

The default environment provided by MinGW does not have the huge list of dependencies that GIMP requires.

Fortunately the email linked above has bash script named grab-stuff.sh (which calls itself a python3 script named "download-mingw-rpm.py", so you have to download both and have python3), which downloads pre-compiled version of all needed dependencies for cross-compiling (it uses OpenSuse repositories as source, but it does not mean at all you need rpm support).

From the root of your cross-compiling prefix ($HOME/w64) run:

bash grab-stuff.sh

You will notice in particular a new usr/ folder, and inside i686-w64-mingw32/ and x86_64-w64-mingw32/ sub-folders.

TODO : Make a proper dependency list.

Set your cross-compiling environment

Define the environment variables as described in Hacking:Building. You may also need to reset pkg-config:

export PKG_CONFIG_LIBDIR=

Build BABL

git clone git://git.gnome.org/babl
cd babl
./autogen.sh --prefix=$PREFIX --host=$HOST --enable-introspection=no
make
make install

Build GEGL

git clone git://git.gnome.org/gegl
cd gegl
./autogen.sh --prefix=$PREFIX --host=$HOST --enable-introspection=no --disable-docs --disable-glibtest
make
make install

Build any optional dependency

This step is not necessary if you compile GIMP with the minimum set of dependency as indicated at the next section.

Compression support

Nevertheless if for instance, you needed compression support (hence be able to load and save your images in various compressed format), you would need zlib,libbzip2 and liblzma installed. In particular the cross-compilation environment described on this page has no pre-compiled liblzma. You would need to cross-compile it first yourself.

In my case xz-5.0.4 worked well.

cd ..
wget http://tukaani.org/xz/xz-5.0.4.tar.xz
tar xf xz-5.0.4.tar.xz
rm xz-5.0.4.tar.xz
cd xz-5.0.4
./configure --prefix=$PREFIX --host=$HOST
make
make install

Finally obviously in the GIMP configure step, remove the --without-liblzma option on the autogen.sh command line before compiling GIMP.

You should be able to do similar things for other optional features that you would want on your cross-compiled GIMP.

Alternatively there exists a patch to get compression support working in 32 bit builds.

Multi-Language support

Multi-Language support is installed with the grab-stuff.sh script. Due to a bug in the package mingw32-iso-codes-devel the pkgconfig program can't find the iso-codes package. In this case you will notice, that GIMPs autogen.sh reports

Language selection: no

and the finished GIMP build has no language selector listbox in Edit/Preferences/Interface. To solve this, copy $HOME/w64/usr/$HOST/sys-root/mingw/share/pkgconfig/iso-codes.pc to $HOME/w64/usr/$HOST/sys-root/mingw/lib/pkgconfig before executing autogen.sh or configure for GIMP. Note you have to do this for every value of $HOST you want to build (e.g. i686 and x86_64 architecture). Also merge the MinGW and GIMP build folders when installing it on Windows (see the Troubleshooting section).

Build GIMP

cd ..
git clone git://git.gnome.org/gimp
cd gimp
./autogen.sh  --prefix=$PREFIX  --host=$HOST \
    --enable-introspection=no \
    --disable-glibtest \
    --disable-gtktest \
    --disable-docs \
    --without-libjpeg \
    --disable-python \
    --without-xmc \
    --without-dbus \
    --without-libzma \
make
make install

Install On Windows

To test your compiled installation, I found nothing better than moving the whole tree (in my case $HOME/w64) into Windows, because libraries are dynamically linked, then run $HOME/w64/bin/gimp-2.9.exe under Windows.

If you really want to build a self contained GIMP, you should compile everything as static libraries. GIMP will probably still rely on some external files though, for instance what you find under $HOME/w64/share/gimp/2.0/. Maybe other things. But this will have to be tested if needed.


Troubleshooting

Running gimp-2.x.exe on Windows fails. Error messages about a missing entry point in libglib-2.0-0.dll or a missing bzip2.dll are shown.

Cause:

The missing dll files are in the MinGW binary folder, which is separate from the GIMP folders.

Solution:

To export the GIMP build to Windows properly, use the following steps:

1. On Windows create a folder for the GIMP build, like GIMP-Master.

2. Copy all files from $HOME/w64/$HOST/sys-root/mingw to the newly created folder.

3. Copy all files from your $PREFIX folder to the newly created folder. There are duplicate subfolders, for instance bin, share etc., in both directories. If your filemanager asks you to overwrite them, then confirm.

It's important to keep this order to ensure you overwrite older BABL and GEGL from the grab-stuff.sh script by the newer ones from your build.

At the end you have merged your MinGW installation and the GIMP build to a running GIMP on Windows build. (It also contains the unnecessary MinGW binaries, which are not needed anymore to run GIMP. But for testing purposes you have a running GIMP installation.)

Some fonts, like Sans, are shown improperly

See also the Bugzilla report.

Cause:

The fontconfig package installation writes absolute paths of the building system to fonts.conf and conf.d/*.conf. When GIMP is installed on the Windows target system, these absolute paths become invalid.

Solution:

The bug should be reported to the Fontconfig developers. Meanwhile do on the Windows target system:

1. Close GIMP.

2. Edit the file <GIMP installation folder>\etc\fonts\fonts.conf:

Replace the line <include ignore_missing="yes">$a_directory/conf.d</include> by <include ignore_missing="yes">..\..\share\fontconfig\conf.avail</include>

3. Restart GIMP.

Building GIMP using Microsoft tools

Microsoft Visual Studio comes with its own C compiler. Most of GIMP development is done with the GCC and its MinGW Windows port.

Unfortunately both are not fully compatible, so integrating GCC into the Visual Studio build chain has its flaws, even while it might work in some points.

Because of this you are recommended to use MinGW for building GIMP on Windows.

Building GIMP plug-ins using Microsoft tools

How to build a GIMP plug-in with Visual Studio (archive.org link salvaged, original link, now broken, was: http://registry.gimp.org/node/24883)

Packaging third-party GIMP plug-ins for Windows

Users on the Windows and Mac OSX platforms expect software to be packaged in a self-installing file (an installer). Even though GIMP plugins (whether scripts in Python or Scheme, or executables in the C language) are relatively easy to install, you might want to package them using an installer such as Inno Setup.
