Description Dennis Schridde 2013-01-05 18:12:35 UTC 
It appears app-arch/xz-utils-5.0.4-r1 builds only a static liblzma.a here.

Reproducible: Always

Comment 4 Dennis Schridde 2013-01-05 18:22:30 UTC 
Found the issue:
checking whether the /mnt/ppc64/etc/crossdev/gcc -std=gnu99 linker (/mnt/ppc64/etc/crossdev/ld -m elf64ppc) supports shared libraries... no

Is there a way for portage to force configure to abort in this case?
Comment 5 Dennis Schridde 2013-01-05 18:36:57 UTC 
The bad linker (wrong value for LD) was my fault. Would be nice of portage could somehow make econf/autoconf/configure bail out early in this case, i.e. force shared or static linking.
Comment 6 SpanKY gentoo-dev 2013-01-06 01:42:50 UTC 
that makes no sense.  there are targets which don't support dynamic linking.

But in the case of xz-utils, it obviously requires shared-object support. So IMO it would make sense...

no, it doesn't.  it depends entirely on the target whether a shared lib is used.

Apparently the app-arch/xz-utils-5.0.4-r1 ebuild calls gen_usr_ldscript, which needs a shared library?

for some targets, yes.  but not all.
