PACKAGE_SNAP_LIB_SYMLINKS renames libraries based on their SONAME so
that they can be found directly rather than going via symlinks that
would be created by ldconfig. For example, without
PACKAGE_SNAP_LIB_SYMLINKS in ${libdir} we have:libharfbuzz.so.0 -> libharfbuzz.so.0.20600.4 libharfbuzz.so.0.20600.4 but with PACKAGE_SNAP_LIB_SYMLINKS="1" we have just: libharfbuzz.so.0 Unfortunately, this renaming is done based on the SONAME which breaks packages like mesa which install a single library with multiple hard links: -rwxr-xr-x root/root 13593488 2021-12-07 12:26 ./usr/lib/dri/i915_dri.so -rwxr-xr-x root/root 13137328 2021-12-07 12:26 ./usr/lib/dri/i965_dri.so hrwxr-xr-x root/root 0 2021-12-07 12:26 ./usr/lib/dri/iris_dri.so link to ./usr/lib/dri/i915_dri.so hrwxr-xr-x root/root 0 2021-12-07 12:26 ./usr/lib/dri/kms_swrast_dri.so link to ./usr/lib/dri/i915_dri.so hrwxr-xr-x root/root 0 2021-12-07 12:26 ./usr/lib/dri/nouveau_vieux_dri.so link to ./usr/lib/dri/i965_dri.so hrwxr-xr-x root/root 0 2021-12-07 12:26 ./usr/lib/dri/r200_dri.so link to ./usr/lib/dri/i965_dri.so hrwxr-xr-x root/root 0 2021-12-07 12:26 ./usr/lib/dri/radeon_dri.so link to ./usr/lib/dri/i965_dri.so hrwxr-xr-x root/root 0 2021-12-07 12:26 ./usr/lib/dri/swrast_dri.so link to ./usr/lib/dri/i915_dri.so The SONAME for i915_dri.so (and therefore all the other names that link to the same file) is libgallium_dri.so. This means that PACKAGE_SNAP_LIB_SYMLINKS causes do_package to successfully rename the first name found to libgallium_dri.so. A similar thing happens to i965_dri.so with its SONAME of libmesa_dri_drivers.so. The order is not deterministic, so this means that although every build will be missing one name, it's not always the same one. -rwxr-xr-x root/root 13593488 2021-11-30 15:17 ./usr/lib/dri/i915_dri.so hrwxr-xr-x root/root 0 2021-11-30 15:17 ./usr/lib/dri/kms_swrast_dri.so link to ./usr/lib/dri/i915_dri.so hrwxr-xr-x root/root 0 2021-11-30 15:17 ./usr/lib/dri/libgallium_dri.so link to ./usr/lib/dri/i915_dri.so -rwxr-xr-x root/root 13137328 2021-11-30 15:17 ./usr/lib/dri/libmesa_dri_drivers.so hrwxr-xr-x root/root 0 2021-11-30 15:17 ./usr/lib/dri/nouveau_vieux_dri.so link to ./usr/lib/dri/libmesa_dri_drivers.so hrwxr-xr-x root/root 0 2021-11-30 15:17 ./usr/lib/dri/r200_dri.so link to ./usr/lib/dri/libmesa_dri_drivers.so hrwxr-xr-x root/root 0 2021-11-30 15:17 ./usr/lib/dri/radeon_dri.so link to ./usr/lib/dri/libmesa_dri_drivers.so hrwxr-xr-x root/root 0 2021-11-30 15:17 ./usr/lib/dri/swrast_dri.so link to ./usr/lib/dri/i915_dri.so This renaming means that the library cannot be found at runtime. The simplest way to avoid this renaming is to only snap libraries that would be processed by ldconfig.
