Summary: multilib LD_LIBRARY_PATH prevents configuration of
target libraries
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: [email protected]
ReportedBy: [email protected]
config-ml.in adjusts LD_LIBRARY_PATH for multilib target libraries. This
apparently was introduced to ensure that applications created by configure in
multilib directories find the correct libraries:
http://gcc.gnu.org/ml/gcc-patches/2000-08/msg00666.html
However, GCC cc1 now relies on libstdc++ via libppl and LD_LIBRARY_PATH will
specify the 64 bit directory for the 64 bit multilib of a target library:
/tmp/201012005/powerpc-ibm-aix5.3.0.0/ppc64/libstdc++-v3/src/.libs
If libstdc++-v3 is configured and built before libgfortran, for example, 64 bit
libgfortran configure will fail because 32 bit cc1 finds the wrong version of
libstdc++-v3. LD_LIBRARY_PATH is affecting the host path, not only the target
path.
I am not sure why this started to fail on AIX now (timing issue?), but it
causes a bootstrap failure of target libraries.
