Bug#631452: Does not find libraries from multiarch directories

[Michael Biebl]

Package: gobject-introspection
Version: 0.10.8-1
Severity: important
File: /usr/bin/dh_girepository

Building epiphany-browser, I get:
dh_girepository -pepiphany-browser -lsrc
dh_girepository: Could not find library libm.so.6

libm.so.6 is installed at /lib/i386-linux-gnu/libm.so.6

dh_girepository uses:

my $arch_triplet = `dpkg-architecture -qDEB_BUILD_GNU_TYPE`;
my @libdirs = ("/lib/$arch_triplet", "/lib", "/usr/lib/$arch_triplet",
"/usr/lib", @privlibdirs);

dpkg-architecture -qDEB_BUILD_GNU_TYPE = i486-linux-gnu

[01:24:41] <mbiebl> having some troubles with dh_girepository and multi-arch
[01:25:03] <mbiebl> dh_girepository uses:
[01:25:10] <mbiebl> my $arch_triplet = `dpkg-architecture -qDEB_BUILD_GNU_TYPE`;
[01:25:10] <mbiebl> my @libdirs = ("/lib/$arch_triplet", "/lib", "/usr/lib/$arch_triplet", "/usr/lib", @privlibdirs);
[01:25:37] <mrvn> s/DEB_BUILD_GNU_TYPE/DEB_BUILD_MULTIARCH/
[01:25:41] <mbiebl> but dpkg-architecture -qDEB_HOST_GNU_TYPE = i486-linux-gnu
[01:26:07] <vorlon> mbiebl: then... dh_girepository is wrong :)
[01:26:13] <mrvn> DEB_HOST_GNU_TYPE=i486-linux-gnu
[01:26:13] <mrvn> DEB_HOST_MULTIARCH=i386-linux-gnu
[01:26:28] <mbiebl> mrvn, vorlon: thanks
[01:26:44] <vorlon> http://wiki.debian.org/Multiarch/Implementation documents the various build-deps you need to use DEB_HOST_MULTIARCH
[01:28:54] <vorlon> mbiebl: btw, AIUI gir is a tricky one in general for cross-compilation, but at least in principle this should be *HOST*, not BUILD
[01:30:20] <mbiebl> vorlon: so, DEB_HOST_MULTIARCH instead of DEB_BUILD_GNU_TYPE?
[01:31:12] <mrvn> mbiebl: MULTIARCH for sure. HOST if you mean the dir on the system where the deb will be installed on in the end and BUILD if you mean the dir the building system happens to use.
