Hello,
This untested patch cleans up a number of hard-coded -fPIC
entries in archive_cmds and archive_expsym_cmds settings,
and adds $pic_flag to all that use GCC on ELF systems.
However, the patch may also change the link command lines
for some non-GCC compilers as well. It needs testing.
In _LT_LANG_CXX_CONFIG, hpux10|hpux11, GXX, hppa*64* case,
the -fPIC there is probably bogus and can be removed, but
that can be another patch (and I haven't tested that either.)
Thanks,
Ralf
