Installation instructions for GIMP @GIMP_APP_VERSION@
|
|
---------------------------------------
|
|
|
|
There are some basic steps to building and installing GIMP.
|
|
|
|
GIMP @GIMP_APP_VERSION@ replaces earlier GIMP 2.99.x versions. It is advised to
|
|
uninstall them before installing GIMP @GIMP_APP_VERSION@. Since libgimp* libraries
|
|
and data are all versionned anyway, it is possible to keep your older
|
|
GIMP 2.x installation in parallel to GIMP @GIMP_APP_VERSION@ on a same prefix.
|
|
|
|
GIMP @GIMP_APP_VERSION@ is not backward compatible with GIMP 2.10 and earlier
|
|
versions. Plug-ins and scripts written for GIMP 2.10, 2.8, 2.6 or
|
|
earlier GIMP 2.x versions will not work because the API changed.
|
|
|
|
The most important part is to make sure the requirements for a build
|
|
are fulfilled. We depend on a number of tools and libraries which are
|
|
listed below. For libraries this means you need to also have the
|
|
header files installed.
|
|
|
|
This file is generated (versions are filled by our build system) and
|
|
focuses on keeping an up-to-date list of dependencies intended to
|
|
packagers, contributors or whoever wants to compile GIMP from source.
|
|
Building and running self-built software often requires more setup, in
|
|
particular environment variables so that your system knows where to
|
|
find the various pieces of the software. The following document can
|
|
help in that regard:
|
|
|
|
https://developer.gimp.org/core/setup/build/
|
|
|
|
|
|
******************************************************************
|
|
* Unless you are experienced with building software from source, *
|
|
* you should not attempt to build all these libraries yourself! *
|
|
* We suggest that you check if your distributor has development *
|
|
* packages of them and use these instead. *
|
|
******************************************************************
|
|
|
|
|
|
1. You need to have installed a recent version of pkg-config (>= @GIMP_PKGCONFIG_VERSION@) available
|
|
from https://www.freedesktop.org/software/pkgconfig/.
|
|
The compatible pkgconf utility would also work.
|
|
|
|
2. You need gettext version 0.19.8 or newer. Older versions did not have support yet
|
|
for certain file formats.
|
|
|
|
3. You need to have GEGL version @GEGL_REQUIRED_VERSION@ or newer and babl version
|
|
@BABL_REQUIRED_VERSION@ or newer. You can get them from https://gegl.org/ or clone
|
|
them from the GNOME git repository:
|
|
|
|
https://gitlab.gnome.org/GNOME/babl.git
|
|
https://gitlab.gnome.org/GNOME/gegl.git
|
|
|
|
GEGL must be built with Cairo support, i.e. -Dcairo=enabled option (required
|
|
for some mandatory operations such as "gegl:npd").
|
|
|
|
Introspection must be enabled for both babl and GEGL with -Denable-gir=true
|
|
and -Dintrospection=true respectively. The only case where we don't build
|
|
GIR data is when cross-compiling because of the difficulty to make cross-tools
|
|
for GObject Introspection.
|
|
Nevertheless if you have working GIR cross-tools, you can force the expected
|
|
behavior with GIMP's meson option -Dcan-crosscompile-gir=true
|
|
|
|
Optional:
|
|
|
|
- build GEGL with libumfpack (SuiteSparse) (`-Dumfpack=enabled`)
|
|
for alternative Matting engine "gegl:matting-levin" and OpenEXR
|
|
library (`-Dopenexr=enabled`) for OpenEXR format support.
|
|
- build GEGL with maxflow (https://github.com/gerddie/maxflow) and
|
|
the option -Dworkshop=true in order to be able to select the
|
|
experimental Paint Select tool in the Playground (operation
|
|
"gegl:paint-select" is needed).
|
|
- The "Show Image Graph" item in the "Debug" menu (hidden by
|
|
default on stable release) requires the GEGL operation
|
|
"gegl:introspect" which is always built but deactivated unless
|
|
the `dot` tool from graphviz is available (runtime dependency).
|
|
|
|
4. You need to have installed GTK version @GTK_REQUIRED_VERSION@ or newer.
|
|
GIMP also needs a recent version of GLib (>= @GLIB_REQUIRED_VERSION@), GDK-Pixbuf
|
|
(>= @GDK_PIXBUF_REQUIRED_VERSION@), and Pango (>= @PANGO_REQUIRED_VERSION@). Sources for these can be grabbed
|
|
from https://download.gnome.org/sources/.
|
|
|
|
5. We use cairo >= @CAIRO_REQUIRED_VERSION@, which is hosted at
|
|
https://www.cairographics.org/.
|
|
|
|
6. We require PangoCairo, a Pango backend using Cairo. Make sure you
|
|
have Cairo, FreeType2 and fontconfig installed before you compile
|
|
Pango. GIMP depends on freetype2 being newer than version @FREETYPE2_REQUIRED_VERSION@
|
|
and fontconfig @FONTCONFIG_REQUIRED_VERSION@ or newer. Older versions are known to have
|
|
bugs that seriously affect the stability of GIMP.
|
|
|
|
On Windows, we recommend fontconfig 2.13.95 (or over) where support
|
|
of fonts in user directory (Windows 1809 feature) appeared.
|
|
|
|
We also require HarfBuzz @HARFBUZZ_REQUIRED_VERSION@ or newer, an OpenType text shaping
|
|
tool. As this is a dependency for Pango, you will likely have it
|
|
installed, but you may have to install a development package for
|
|
the headers.
|
|
|
|
7. The file-compressor plug-in requires zlib, libbzip2, and liblzma to
|
|
be installed. All these libraries are required dependencies.
|
|
|
|
8. For metadata access GIMP requires the gexiv2 @GEXIV2_REQUIRED_VERSION@ or newer library.
|
|
It is hosted at: https://wiki.gnome.org/Projects/gexiv2
|
|
|
|
9. libpng, libjpeg, libtiff, librsvg and lcms are hard dependencies
|
|
that can not be disabled. poppler is also a hard dependency because
|
|
PDF is too common nowadays for it to be an option (at least for
|
|
import); and poppler-data (CJK and Cyrillic support in PDF) is also
|
|
required because no languages should be considered "second class
|
|
citizen". If we support PDF, let's support it properly, i.e.
|
|
exhaustively.
|
|
|
|
There might be some issues with librsvg, based on the fact newer
|
|
versions are in Rust which is not buildable on all platforms. Yet
|
|
SVG support was deemed too important to be considered "optional"
|
|
for a decent graphics activity. Nevertheless a packager really
|
|
intent to have GIMP running on an architecture with no Rust support
|
|
could still:
|
|
|
|
1) easily patch out the file-svg plug-in from build system;
|
|
2) build GIMP with -Dvector-icons=false. Ironically librsvg is
|
|
needed at build time for this option, in order to create PNG
|
|
variants of icons (making librsvg unneeded at runtime). So all it
|
|
takes is to have a build machine with librsvg to create the PNG
|
|
icons, package and deliver them for machines without librsvg.
|
|
|
|
This is the compromise we came with, i.e. officially making SVG a
|
|
first-class file format, yet explaining how you could ignore it if
|
|
you really wanted or needed to.
|
|
|
|
10. For MyPaint brushes, brushlib (libmypaint) @LIBMYPAINT_REQUIRED_VERSION@ is used.
|
|
The libmypaint repository is hosted at:
|
|
|
|
https://github.com/mypaint/libmypaint
|
|
|
|
If installing from repository, do not install the master branch!
|
|
Checkout the last tag "v1.y.z" from `libmypaint-v1` branch instead
|
|
(for instance "v1.6.1" tag at time of writing), or simply install
|
|
from a tarball or from your favorite package manager.
|
|
|
|
In particular, do NOT install tags or release tarballs versioned
|
|
"v2.y.z". GIMP depends on the version 1 of libmypaint and is
|
|
incompatible with the version 2 (which is still experimental anyway
|
|
and has no stable release at time of writing).
|
|
|
|
11. We also need the mypaint-brushes data package:
|
|
|
|
https://github.com/mypaint/mypaint-brushes
|
|
|
|
If installing from repository, install from branch "v1.3.x" or the
|
|
last tag "v1.y.z" (e.g. "v1.3.1" at time of writing).
|
|
In particular do NOT install from `master` branch which installs
|
|
brushes incompatible with GIMP (the `master` branch and v2 brushes
|
|
are targeted to software using recent libmypaint which GIMP wasn't
|
|
ported to yet).
|
|
|
|
Also this is a data packages and therefore it will install the
|
|
pkg-config file inside `$PREFIX/share/pkgconfig/`. If you install
|
|
mypaint-brushes from repository in a non-standard prefix, you will
|
|
have to make sure your $PKG_CONFIG_PATH environment variable also
|
|
lists `$PREFIX/share/pkgconfig/`.
|
|
|
|
12. GIMP uses GLib's GIO library to handle file URIs and any I/O in
|
|
general, transparently, regardless where the file is stored, i.e.
|
|
locally, remotely, with which scheme, and so on. GIO in turn
|
|
supports various backends through modules. We don't know all the
|
|
modules available but since HTTP and HTTPS are so pervasive
|
|
nowadays, we kind of consider a least GIO modules for these schemes
|
|
mandatory (it allows to open from a pasted URL or just drag'n drop
|
|
from e.g. a browser).
|
|
|
|
For HTTP support (and many other schemes), on Linux at least, you
|
|
should install `gvfs`:
|
|
|
|
https://wiki.gnome.org/Projects/gvfs
|
|
|
|
It is unclear whether `gvfs` can be built and installed on other
|
|
platforms such as Windows and macOS.
|
|
|
|
For HTTPS support, you should install `glib-networking`:
|
|
|
|
https://gitlab.gnome.org/GNOME/glib-networking
|
|
|
|
Of course there might be more modules providing support of more
|
|
storage backends. Ideally GIMP would have support to load from any
|
|
backend so packaging together with more GIO modules or recommending
|
|
them in a package manager would be ideal. In any case, installing
|
|
the ones for HTTP and HTTPS seems like the minimum nowadays.
|
|
|
|
13. You may want to install other third party libraries or programs
|
|
that are needed for some of the available plug-ins. We recommend
|
|
to check that the following libraries are installed: openjpeg,
|
|
libmng, libwmf, libaa and libgs (Ghostscript).
|
|
|
|
14. HEIF support depends on the libheif library. If you don't have
|
|
access to pre-built packages, the code is available at:
|
|
|
|
https://github.com/strukturag/libheif
|
|
|
|
Make sure you build libheif with libde265 and libx265 support (for
|
|
respectively decoding and encoding of HEVC, i.e. HEIC files), and
|
|
libaom decoder and encoder (for AV1, i.e. AVIF files), otherwise
|
|
the plug-in is mostly useless.
|
|
|
|
15. GObject Introspection requires the following dependencies to be
|
|
built and installed with introspection as well: babl, cairo,
|
|
GdkPixbuf, GEGL, GIO, GLib, GObject and GTK.
|
|
|
|
16. Windows builds can now generate backtrace logs upon a crash.
|
|
The logs will be available in: %APPDATA%\GIMP\@GIMP_APP_VERSION@\CrashLog\
|
|
The feature depends on Dr.MinGW's ExcHndl library:
|
|
|
|
https://github.com/jrfonseca/drmingw
|
|
|
|
17. Optional step if compiling GIMP from git (unneeded from tarball): you need
|
|
to initialize submodules with command `git submodule update --init`.
|
|
|
|
18. Configure GIMP by running `meson _build`. You may want to pass some
|
|
options to it, see below.
|
|
|
|
19. Build GIMP by running `ninja -C _build'.
|
|
|
|
20. Install GIMP by running `ninja -C _build install'. In order to
|
|
avoid clashes with other versions of GIMP, we install a binary
|
|
called gimp-@GIMP_APP_VERSION@. By default there's also a link created so that
|
|
you can type 'gimp' to start gimp-@GIMP_APP_VERSION@.
|
|
|

|
Generic instructions for configuring and compiling auto-configured
|
|
packages are included below. Here is an illustration of commands that
|
|
might be used to build and install GIMP. The actual configuration,
|
|
compilation and installation output is not shown.
|
|
|
|
% tar xvf gimp-@GIMP_VERSION@.tar.xz # unpack the sources
|
|
% cd gimp-@GIMP_VERSION@ # change to the toplevel directory
|
|
% meson _build # `configure' step
|
|
% ninja -C _build # build GIMP
|
|
% ninja -C _build install # install GIMP
|
|
|
|
|
|
The `configure' step examines your system, and adapts GIMP to run on
|
|
it. The script has many options, some of which are described in the
|
|
generic instructions included at the end of this file. All of the
|
|
options can be listed using the command `meson configure' if you
|
|
successfully configured already, or by reading the file `meson_options.txt`.
|
|
There are several special options the GIMP configure script recognizes.
|
|
These are:
|
|
|
|
-Dvector-icons=false This option installs raster icons instead of
|
|
vector icons.
|
|
|
|
-Drelocatable-bundle=yes This option forces GIMP to search some
|
|
resources (e.g. MyPaint brushes or libwmf fonts) relatively to the
|
|
running prefix, rather than using build-time paths.
|
|
|
|
-Dansi=true This option causes stricter ANSI C checking to be
|
|
performed when compiling with GCC. The default is for strict
|
|
checking to be disabled. NOTE: This option is intended primarily as
|
|
a convenience for developers.
|
|
|
|
-Dgimpdir=DIR. This option changes the default directory GIMP uses to
|
|
search for its configuration files from ~/.config/GIMP/@GIMP_APP_VERSION@ (the
|
|
directory .config/GIMP/@GIMP_APP_VERSION@ in the user's home directory) to
|
|
~/.config/DIR/@GIMP_APP_VERSION@.
|
|
If DIR is an absolute path, the directory will be changed to DIR.
|
|
|
|
-Dshmem-type=[none|sysv|posix|win32|auto]. This option allows you to
|
|
specify how image data is transported between the core and plug-ins.
|
|
Usually the best way to do this is detected automatically.
|
|
|
|
-Daa=disabled The AA plug-in needs libaa and configure checks for
|
|
its presence. Use -Daa=disabled if you run into problems.
|
|
|
|
-Dxpm=disabled The XPM plug-in needs libxpm and configure checks
|
|
for its presence. If for some reason you don't want to build the
|
|
XPM plug-in even though the library is installed, use
|
|
-Dxpm=disabled to disable it explicitly.
|
|
|
|
-Dmng=disabled The MNG plug-in needs libmng and configure checks
|
|
for its presence. If for some reason you don't want to build the
|
|
MNG plug-in even though the library is installed, use
|
|
-Dmng=disabled to disable it explicitly.
|
|
|
|
-Dwmf=disabled The WMF plug-in needs libwmf2 and configure checks for
|
|
its presence. Use -Dwmf=disabled if you run into problems.
|
|
|
|
-Dwebkit-unmaintained=true We do not recommend to install the Help
|
|
browser and Webpage plug-ins anymore. If for some reason you want
|
|
these anyway, you can force the build with this explicit option.
|
|
|
|
-Dprint=false If for some reason you don't want to build the Print
|
|
plug-in based on the GtkPrint API, you can build with -Dprint=false.
|
|
|
|
-Dalsa=disabled If you don't want to compile ALSA support into the
|
|
MIDI input controller module, you can use the -Dalsa=disabled option.
|
|
|
|
-Dlinux-input=disabled If you don't want to compile the Linux Input
|
|
controller module, you can use the -Dlinux-input=disabled option.
|
|
|
|
-Dgi-docgen=enabled|disabled This option controls whether the libgimp
|
|
C API references will be created using gi-docgen.
|
|
|
|
-Dg-ir-doc=true This option controls whether the libgimp API
|
|
references for some binding languages will be created using
|
|
g-ir-doc-tool and yelp-build.
|
|
|
|
-Denable-multiproc=false This option allows you to disable support for
|
|
multiple processors. It is enabled by default.
|
|
|
|
-Dwith-sendmail[=PATH] This option is used to tell GIMP to send email
|
|
through sendmail instead of xdg-email. You can optionally indicate
|
|
where to find the sendmail command. Otherwise sendmail will simply
|
|
be searched in your $PATH at runtime.
|
|
|
|
-Denable-default-bin=false Use this option if you don't want to make
|
|
gimp-@GIMP_APP_VERSION@ the default GIMP installation. Otherwise a link called
|
|
gimp pointing to the gimp-@GIMP_APP_VERSION@ executable will be installed.
|
|
|
|
-Denable-console-bin=false Use this option if you don't want the
|
|
gimp-console binary to be built in addition to the standard binary.
|
|
gimp-console is useful for command-line batch mode or as a server.
|
|
|
|
-Djavascript=false If for some reason you don't want to install the
|
|
JavaScript plug-ins, you can use -Djavascript=false.
|
|
|
|
-Dlua=false If for some reason you don't want to install the
|
|
Lua plug-ins, you can use -Dlua=false.
|
|
|
|
-Dvala-plugins=disabled If for some reason you don't want to install the
|
|
Vala plug-ins, you can use -Dvala-plugins=disabled.
|
|
|
|
|
|
This list is manually maintained. To get an exhaustive listing of options,
|
|
read `meson_options.txt'.
|
|
Additionally meson supports a wide range of common built-in options. See
|
|
documentation: https://mesonbuild.com/Builtin-options.html
|
|
|
|
The `ninja' command builds several things:
|
|
- A bunch of public libraries in the directories starting with 'libgimp'.
|
|
- The plug-in programs in the 'plug-ins' directory.
|
|
- Some modules in the 'modules' subdirectory.
|
|
- The main GIMP program 'gimp-@GIMP_APP_VERSION@' in `app'.
|
|
|
|
The `ninja install' command installs the GIMP header files associated
|
|
with the libgimp libraries, the plug-ins, some data files and the GIMP
|
|
executable. After running `ninja install' and assuming the build process
|
|
was successful you should be able to run `gimp'.
|
|
|
|
|
|
When configure fails
|
|
======================
|
|
|
|
The configuration step uses pkg-config, a tool that replaces the old foo-config
|
|
scripts. The most recent version is available from
|
|
https://www.freedesktop.org/software/pkgconfig/
|
|
|
|
'configure' tries to compile and run a short GTK program. There are
|
|
several reasons why this might fail:
|
|
|
|
* pkg-config could not find the file 'gtk+-3.0.pc' that gets installed
|
|
with GTK. (This file is used to get information about where GTK+ is
|
|
installed.)
|
|
|
|
Fix: Either make sure that this file is in the path where pkg-config
|
|
looks for it (try 'pkg-config --debug' or add the location of
|
|
gtk+-3.0.pc to the environment variable PKG_CONFIG_PATH before running
|
|
configure.
|
|
|
|
* Libraries you installed are not found when you attempt to start GIMP.
|
|
The details of how to fix this problem will depend on the system:
|
|
|
|
On Linux and other systems using ELF libraries, add the directory to
|
|
holding the library to /etc/ld.so.conf or to the environment variable

LD_LIBRARY_PATH, and run 'ldconfig'.
|
|
|
|
On other systems, it may be necessary to encode this path
|
|
into the executable, by setting the LDFLAGS environment variable
|
|
before running configure. For example:
|
|
|
|
LDFLAGS="-R/home/joe/lib" ./configure
|
|
or
|
|
LDFLAGS="-Wl,-rpath -Wl,/home/joe/lib" ./configure

* An old version of the GTK libraries was found instead of
|
|
your newly installed version. This commonly happens if a
|
|
binary package of GTK was previously installed on your system,
|
|
and you later compiled GTK from source.
|
|
|
|
Fix: Remove the old libraries and include files. If you are afraid
|
|
that removing the old libraries may break other packages supplied by
|
|
your distributor, you can try installing GLib, GTK and other
|
|
libraries in a different prefix after setting the environment
|
|
variable PKG_CONFIG_LIBDIR to point to lib/pkgconfig/ in that new
|
|
prefix so that it does not try to read the *.pc files from the
|
|
default directory (/usr/lib/pkgconfig). However, removing the old
|
|
packages is often the easier solution.

When meson configure fails on plug-ins
|
|
======================================
|
|
|
|
There are some GIMP plug-ins that need additional third-party libraries
|
|
installed on your system. For example to compile the plug-ins that load
|
|
and save JPEG, PNG or TIFF files you need the related libraries and header
|
|
files installed, otherwise you'll get a message that plug-in xyz will not
|
|
be built.
|
|
|
|
If you are sure that those libraries are correctly installed, but configure
|
|
fails to detect them, the following might help:
|
|
|
|
Set your LDFLAGS environment variable to look for the library in a certain
|
|
place, e.g. if you are working in a bash shell you would say:
|
|
export LDFLAGS="-L<path_to_library> -L<path_to_another_one>"
|
|
before you run configure.
|
|
|
|
Set your CPPFLAGS environment variable to look for the header file in a
|
|
certain place, e.g. if you are working in a bash shell you would say:
|
|
export CPPFLAGS="-I<path_to_header_file> -I<path_to_another_one>"
|
|
before you run meson.
