Description Bernd 2019-08-19 10:27:21 UTC

When trying to emerge media-sound/denemo-2.3.0 with USE=jack enabled it fails with

/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: error: //usr/lib/libjack.so: incompatible target
/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: warning: skipping incompatible /usr/lib/libxml2.so while searching for xml2

followed by more similar errors.

I first was thinking, this might be related to bug #691274, but now I think, it might have several causes.

When manually changing the libdir entry from in /usr/lib64/pkgconfig/rubberband.pc to read ${exec_prefix}/lib64, the build succeeds even with USE=jack enabled.

What I don't understand, why libtool is picking jack to convert the 'relative' library -ljack into an absolute path /usr/lib/libjack.so (see below). There are a bunch of other libraries, which also get linked into the binaries and are available in both abi_x86_64 and abi_x86_32 on my machine. The configure.ac snippet which searches for jack, looks unconspicuous to me.

Building without USE=jack finishes the build.
I'm going to attach build logs for several use cases on this.
