Recommended patch (required if installing Xorg into
/opt):
https://www.linuxfromscratch.org/patches/blfs/svn/glycin-2.1.5-xorg_prefix-1.patch
bubblewrap-0.11.2 (runtime), Fontconfig-2.18.3, GLib-2.88.3 (GObject Introspection recommended), Little CMS-2.19.1, libseccomp-2.6.1, and rustc-1.97.1
An Internet connection is needed for building this package. The system certificate store may need to be set up with make-ca-1.16.1 before building this package.
libheif-1.23.1, libjxl-0.12.0, librsvg-2.62.3, and Vala-0.56.19
Gi-DocGen-2026.1, GTK-4.22.4 (for the test suite), and libopenraw
If installing Xorg into /opt,
download the needed Rust crates now and apply a patch to allow
accessing $XORG_PREFIX/lib from the
sandbox (note that the patch requires XORG_PREFIX to be set properly for both the current
user and for root following
Xorg build environment
before building glycin):
cargo vendor && patch -Np1 -i ../glycin-2.1.5-xorg_prefix-1.patch
Fix a build error when a system libglycin is not yet installed:
sed -e "s/get_option('libglycin-gtk4')/(& or get_option('glycin-thumbnailer'))/" \
-i meson.build
Install glycin by running the following commands:
mkdir build &&
cd build &&
meson setup --prefix=/usr \
--buildtype=release \
-D libglycin-gtk4=false \
-D tests=false .. &&
ninja
If you have installed Gi-DocGen-2026.1, you can build the documentation by issuing:
sed "/install_dir:.*doc/s|,$| / 'glycin-' + meson.project_version()&|" \
-i ../libglycin/meson.build &&
meson configure -D capi_docs=true &&
ninja
To test the results, ensure GTK-4.22.4 is installed, then issue: meson configure -D tests=true && ninja test. One test is known to fail with shared-mime-info-2.5.1.
Now as the root user:
ninja install
-D glycin_gtk4=false: This
parameter disables the build of libglycin-gtk4. This library will be built
separately as libglycin-gtk4 from
glycin-2.1.5, to avoid a circular dependency.
-D glycin-loaders=...: Use this option
to specify the image loaders to be built. The default is
glycin-heif,glycin-image-rs,glycin-jxl,glycin-svg,
covering support for all commonly used image formats. You may
remove the glycin-heif, glycin-jxl, or glycin-svg loader if the corresponding recommended
dependency is not installed, but doing so will cause test failures
and hamper the functionality of this package. There is also a
loader for the RAW format but it is not enabled by default.
-D vapi=false: This option allows
building this package without Vala-0.56.19 installed.
