libtool has wrong sys_lib_search_path_spec on x86_64
Last modified: 2007-04-18 12:55:30 EDT
Description of problem: when libtool is trying to resolve inter-library dependencies, it is looking in sys_lib_search_path_spec to find those libraries. Unfortunately, even on x86_64, the path is set to "/usr/lib /lib /usr/local/lib", instead of "/usr/lib64 /lib64 /usr/local/lib64". Thus libtool assumes that the shared version of the dependant library is not installed, and build a static lib instead :( Version-Release number of selected component (if applicable): How reproducible: I've encountered the problem while trying to build transcode plugins, but it is quite a generic error. I've built a new libtool RPM including a patch from SuSE SLES8 (x86_64) that fixes this issue. I'm going to attach the patch to this bug report
Created attachment 92759 [details] patch (can be used via %patch16 -p0 in libtool-1.5-3.src.rpm)
Thank you for the report. I just note that at least /usr/bin/libtool is using lib64 on x86_64. Also right after the 2nd hunk of your patch in libtool.m4 I see code like: # Find out which ABI we are using (multilib Linux x86_64 hack). libsuff= case "$host_cpu" in x86_64*|s390x*) echo '[#]line __oline__ "configure"' > conftest.$ac_ext if AC_TRY_EVAL(ac_compile); then case `/usr/bin/file conftest.$ac_objext` in *64-bit*) libsuff=64 ;; esac fi rm -rf conftest* ;; *) ;; esac sys_lib_dlsearch_path_spec="/lib${libsuff} /usr/lib${libsuff}" sys_lib_search_path_spec="/lib${libsuff} /usr/lib${libsuff} /usr/local/lib${libsuff}" ;; which should admittedly should be extended to ppc at least, but is that not sufficient, or am I missing something?
I see a few references to x86_64-specific libraries in /usr/lib/gcc, but otherwise rawhide's /usr/bin/libtool appears to list /usr/lib64 for $sys_lib_search_path_spec. Please re-open if you encounter any similar problems in the future. Thanks.

The special $libsuff stuff seems to have completely disappeared from libtool.m4! This is a nasty regression.
The old multilib patch was not acceptable for upstream Libtool, and a new one is being developed. libtool-1.5.10-1.1 in dist-fc4-scratch includes a new, experimental multilib patch. *** This bug has been marked as a duplicate of 138742 ***
