[Pkg-alsa-devel] Bug#369469: libasound2: invalid datadir path - alsa.conf not found

[Robin Gareus]

Package: libasound2
Version: 1.0.11-6
Severity: important


/usr/lib/libasound.so.2.0.0  is compiled with datadir=/home/jordi/svn/pkg-alsa/trunk/build-area/alsa-lib-1.0.11/${prefix}/share/alsa 

libasound2 searches for alsa.conf in the build-dir rather than /usr/share/alsa/ - thus alsa apps fail to work until I create /usr/share/alsa as /home/jordi/...  or set the ALSA_CONFIG_PATH enviroment variable.

adding  --datadir=/usr/share  to the configure lines in debian/rules and rebuilding libasound2 helped me out.

alsa-lib-1.0.11/configure.in:65 says:

eval dir="$datadir"
case "$dir" in
/*) ;;
*) dir="$PWD/$dir"
esac


 \${prefix} is not replaced (maybe due to 40_relibtoolise.dpatch ??).
 datadir starts with '$' instead of '/' -> pwd is prepended and 
 '..${prefix}..' ends up in include/config.h and bibuild/include/config.h
