dev-libs/redland-1.0.16[berkdb] fails to detect multilib sys-libs/db, because it tries to extract version from header, which is now a wrapper header: configure.ac: for bdbc_version in 5.3 5.2 5.1 5.0 4.9 4.8 4.7 4.6 4.5 4.4 4.3 4.2 4.1 4.0 4 3.3 3.2 3.1 3 2; do bdbc_major=`echo $bdbc_version | sed -e 's/^\(.\).*$/\1/'`; bdbc_version2=`echo $bdbc_version | sed -e 's/^\(.\).\(.\)$/\1\2/'` for bdbc_prefix in $extraprefix /usr/local/BerkeleyDB.$bdbc_version /usr/local /opt/local /usr; do bdbc_libdir=$bdbc_prefix/lib for bdbc_incdir in $bdbc_prefix/include/db$bdbc_version $bdbc_prefix/include/db$bdbc_version2 $bdbc_prefix/include/db$bdbc_major $bdbc_prefix/include ; do if test -r $bdbc_incdir/db.h ; then ==> header_bdbc_version=`sed -ne 's/^.*DB_VERSION_STRING.*Berkeley DB \(...\).*/\1/p' $bdbc_incdir/db.h` if test "X$header_bdbc_version" = "X$bdbc_version" ; then for bdbc_name in db-$bdbc_version db$bdbc_version db-$bdbc_version2 db$bdbc_version2; do bdbc_libdir_multiarch= if test "X$multiarch" != X; then bdbc_libdir_multiarch=$bdbc_libdir/$multiarch fi for bdbc_libdir2 in $bdbc_libdir_multiarch $bdbc_libdir $bdbc_libdir/db$bdbc_version $bdbc_libdir/db$bdbc_version2; do if test -r $bdbc_libdir2/lib$bdbc_name.a -o -r $bdbc_libdir2/lib$bdbc_name.so -o -r $bdbc_libdir2/lib$bdbc_name.dylib; then bdb_version=$bdbc_version bdb_prefix=$bdbc_prefix bdb_include_dir=$bdbc_incdir bdb_lib_dir=$bdbc_libdir2 bdb_dbname=$bdbc_name break 5 fi done done fi fi done done done fi
The result of incorrect code is not a build failure, but detection of incorrect version of sys-libs/db. E.g. if sys-libs/db:4.8 and sys-libs/db:5.3 are installed, then 4.8 will be detected.
I'd guess the easy (and possibly the proper) solution would be to use CPP to obtain the contents for matching. With only multilib db versions, it spawns: checking Oracle Berkeley DB (BDB) version... unknown checking location of BDB libs... /usr/lib checking location of BDB includes... /usr/include configure: WARNING: Cannot find the BDB library name from the files in /usr/lib configure: WARNING: Assuming it is 'db' and will link like -ldb configure: WARNING: Use --with-bdb-dbname=NAME if this is wrong
Also, the list doesn't contain 6.0 though it seems to work :). I think we should use db-use eclass and pass --with-bdb-dbname instead.
(See bug #476376 about 6.0.)
