Installation of libgweather

Fix an issue in the shipped geolocation data: 

patch -Np1 -i ../libgweather-4.4.4-upstream_fix-1.patch

Install libgweather by running the following commands: 

mkdir build &&
cd    build &&

meson setup --prefix=/usr       \
            --buildtype=release \
            -D gtk_doc=false    \
            ..                  &&
ninja

If you have Gi-DocGen-2026.1 installed and wish to build the API documentation for this package, issue: 

sed "s/libgweather_full_version/'libgweather-4.4.4'/" \
    -i ../doc/meson.build                             &&
meson configure -D gtk_doc=true                       &&
ninja

One test needs that the locale files be installed on the system, so it is better to run the tests after installing the package.

Now, as the root user: 

ninja install

To test the results, issue: LC_ALL=C ninja test. One test, metar, is known to fail due to some airport weather information being temporarily unavailable.

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-D gtk_doc=false: Allow building this package without Gi-DocGen-2026.1 installed. If you have Gi-DocGen-2026.1 installed and you wish to rebuild and install the API documentation, a meson configure command will reset this option.
