Installation instructions for PIKA @PIKA_APP_VERSION@
|
||||
---------------------------------------
|
||||
|
||||
There are some basic steps to building and installing PIKA.
|
||||
|
||||
PIKA @PIKA_APP_VERSION@ replaces earlier PIKA 2.99.x versions. It is advised to
|
||||
uninstall them before installing PIKA @PIKA_APP_VERSION@. Since libpika* libraries
|
||||
and data are all versionned anyway, it is possible to keep your older
|
||||
PIKA 2.x installation in parallel to PIKA @PIKA_APP_VERSION@ on a same prefix.
|
||||
|
||||
PIKA @PIKA_APP_VERSION@ is not backward compatible with PIKA 2.10 and earlier
|
||||
versions. Plug-ins and scripts written for PIKA 2.10, 2.8, 2.6 or
|
||||
earlier PIKA 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 PIKA 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.pika.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 (>= @PIKA_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 PIKA'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.
|
||||
PIKA 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. PIKA 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 PIKA.
|
||||
|
||||
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 PIKA 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.
|
||||
|
||||
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 PIKA running on an architecture with no Rust support
|
||||
could still:
|
||||
|
||||
1) easily patch out the file-svg plug-in from build system;
|
||||
2) build PIKA 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". PIKA 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 PIKA (the `master` branch and v2 brushes
|
||||
are targeted to software using recent libmypaint which PIKA 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. PIKA 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 PIKA 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%\PIKA\@PIKA_APP_VERSION@\CrashLog\
|
||||
The feature depends on Dr.MinGW's ExcHndl library:
|
||||
|
||||
https://github.com/jrfonseca/drmingw
|
||||
|
||||
17. Configure PIKA by running `meson _build`. You may want to pass some
|
||||
options to it, see below.
|
||||
|
||||
18. Build PIKA by running `ninja -C _build'.
|
||||
|
||||
19. Install PIKA by running `ninja -C _build install'. In order to
|
||||
avoid clashes with other versions of PIKA, we install a binary
|
||||
called pika-@PIKA_APP_VERSION@. By default there's also a link created so that
|
||||
you can type 'pika' to start pika-@PIKA_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 PIKA. The actual configuration,
|
||||
compilation and installation output is not shown.
|
||||
|
||||
% tar xvf pika-@PIKA_VERSION@.tar.xz # unpack the sources
|
||||
% cd pika-@PIKA_VERSION@ # change to the toplevel directory
|
||||
% meson _build # `configure' step
|
||||
% ninja -C _build # build PIKA
|
||||
% ninja -C _build install # install PIKA
|
||||
|
||||
|
||||
The `configure' step examines your system, and adapts PIKA 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 PIKA configure script recognizes.
|
||||
These are:
|
||||
|
||||
-Dvector-icons=false This option installs raster icons instead of
|
||||
vector icons.
|
||||
|
||||
-Drelocatable-bundle=yes This option forces PIKA 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.
|
||||
|
||||
-Dpikadir=DIR. This option changes the default directory PIKA uses to
|
||||
search for its configuration files from ~/.config/PIKA/@PIKA_APP_VERSION@ (the
|
||||
directory .config/PIKA/@PIKA_APP_VERSION@ in the user's home directory) to
|
||||
~/.config/DIR/@PIKA_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 libpika
|
||||
C API references will be created using gi-docgen.
|
||||
|
||||
-Dg-ir-doc=true This option controls whether the libpika 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 PIKA 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
|
||||
pika-@PIKA_APP_VERSION@ the default PIKA installation. Otherwise a link called
|
||||
pika pointing to the pika-@PIKA_APP_VERSION@ executable will be installed.
|
||||
|
||||
-Denable-console-bin=false Use this option if you don't want the
|
||||
pika-console binary to be built in addition to the standard binary.
|
||||
pika-console is useful for command-line batch mode or as a server.
|
||||
|
||||
-Dpython=false If for some reason you don't want to install the
|
||||
Python plug-ins, you can use -Dpython=false.
|
||||
|
||||
-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 'libpika'.
|
||||
- The plug-in programs in the 'plug-ins' directory.
|
||||
- Some modules in the 'modules' subdirectory.
|
||||
- The main PIKA program 'pika-@PIKA_APP_VERSION@' in `app'.
|
||||
|
||||
The `ninja install' command installs the PIKA header files associated
|
||||
with the libpika libraries, the plug-ins, some data files and the PIKA
|
||||
executable. After running `ninja install' and assuming the build process
|
||||
was successful you should be able to run `pika'.
|
||||
|
||||
|
||||
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 PIKA.
|
||||
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.
|
||||
|
||||
A detailed log of the meson output is written to the file meson-logs/meson-log.txt.
|
||||
This may help diagnose problems.
|
||||
|
||||
|
||||
When meson configure fails on plug-ins
|
||||
======================================
|
||||
|
||||
There are some PIKA 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.
