On my x86_64-unknown-linux-gnu system, the m4 macro AC_LIBTOOL_SYS_DYNAMIC_LINKER in libtool.m4 uses "gcc -print-search-dirs" to set sys_lib_search_path_spec.
Unfortunately, -print-search-dirs lists -m32 library directories, but gcc is in (default) -m64 mode on my system. Consequently libtool tries to link with the wrong library (32 bit when it should be using 64 bit). The particular error message I get is : /usr/local/gcc-4.1.1/x86_64-Linux/lib/../lib/libstdc++.so: could not read symbols: : File in wrong format I can get the appropriate 64-bit directories to search by 'gcc -v -o hello hello.c' from a "hello world" program and then looking at the directories following each -L. If I then hack configure to explicitly set sys_lib_search_path_spec with these directories, then /usr/local/gcc-4.1.1/x86_64-Linux/lib/../lib64/libstdc++.so is used and everything is fine. Unfortunately, I do not have a small example to demonstrate the problem. I found this while trying to compile givaro-3.2.1 (http://www-lmc.imag.fr/Logiciels/givaro/). Any help or suggestions on what should be the appropriate change to AC_LIBTOOL_SYS_DYNAMIC_LINKER to make it work in the multilib environment would be appreciated.
