Since the switch to pkgconf 1.5.3 in commit
4e42366939, the glib-networking package
has been failing to build with:
glib-networking: installs files in /home/naourr/work/instance-0/output/host/i686-buildroot-linux-uclibc/sysroot//home/naourr/work/instance-0/output
This error is due to glib-networking having installed its GIO GnuTLS
module into an invalid location. This invalid location is
$(DESTDIR)$(GIO_MODULE_DIR). GIO_MODULE_DIR is found by using:
pkg-config --variable giomoduledir gio-2.0
Unfortunately, despite the pkgconf fix in commit
7125fc5c1a ("package/pkgconf: add patch
to restore pre-1.5.3 behavior for sysroot prefixing"), the value
returned by pkg-config for giomoduledir remains prefixed by the
sysroot.
This is due to the fact that giomoduledir is defined by default with
the value ${libdir}/gio/modules. When running pkg-config --variable
giomoduledir gio-2.0 with the new pkg-config version, what happens is
that libdir is resolved first, and libdir is one of the variable for
which we add the sysroot prefix. Then later, giomoduledir is
resolved. For this variable, we don't prefix with the
sysroot. However, when resolving the value of giomoduledir, it re-uses
the value of libdir that was already resolved, and this value includes
the sysroot prefix.
There is no simple way to solve this problem within pkg-config. So for
the time being, we take a simple route: make sure giomoduledir isn't
defined in terms of ${libdir}. This is easily done by passing
--with-gio-module-dir to libglib2 configure script.
