Description Khem Raj 2012-08-23 01:30:08 UTC 
pango-querymodules specifies 

-Wl,-rpath -Wl,/usr/lib/../lib to libtool and that gets into ELF and later QA checker detects it and complains


ERROR: QA Issue: pango: /work/x86_64-poky-linux/pango-1.30.0-r0/packages-split/pango/usr/bin/pango-view contains probably-redundant RPATH /usr/lib/../lib
ERROR: QA Issue: pango: /work/x86_64-poky-linux/pango-1.30.0-r0/packages-split/pango/usr/bin/pango-querymodules contains probably-redundant RPATH /usr/lib/../lib
ERROR: QA run found fatal errors. Please consider fixing them.


note that my build host is ubuntu 12.04/x86_64 and target is qemux86-64

this does not happen in dissimilar arches e.g. it builds ok for i586 or ppc


So two questions, 1 somehow libtool is behaving strangely when both build system and target system are same proabably because its able to read files in /usr/lib on build host.

secondly there is a patch to libtool which should have converted this relative path to normal /usr/lib and I do have that patch applied to metadata

it still fails.

the similar error also happened on nightly-build (20120822-1) when build qemux86-64 meta-toolchain-gmae (both i686 and x86_64),log from autobuilder:

Comment 2 Andy Ross 2012-08-24 03:18:58 UTC 
This was latent, and unmasked by oe-core commit 72a924d068, which fixed the warning condition to properly normalize the path before comparing vs. "/usr/lib".  An libtool patch was required to properly normalize the -rpath argument passed to ld, but apparently more treatment is needed.  Specifically, Saul discovered that the many of the .la files produced by libtool have the /usr/lib/../lib construction, including pango and libstdc++.
