Hi -
I'm the maintainer of the lftp package here at Red Hat -
thanks for the great work!
I just tried to compile lftp-3.0.13 for inclusion in
FC4/rawhide, and came accross this niggle that caused
the compile to fail, both on FC4 and RHEL-4 - it seems
the '--tag=CXX' option in the 'CXXLINK' variable in
src/Makefile.in causes the link for shared libraries
to fail - for some reason, libtool tries to create an
executable with non-existent crtso objects. Removing
the '--tag=CXX' enables the link to work OK:

The weird thing is, the /usr/lib/gcc/i386-redhat-linux/3.4.2
directory does not exist ; that was the PREVIOUS version of
the compiler for FC3 which is no longer installed at all on FC4 .
On RHEL-4, where the current compiler is 3.4.3, the
/usr/bin/libtool --tag=CXX --mode=link
command tries to link in objects from /usr/lib/gcc/i386-redhat-linux/3.4.1,
which also does not exist.
This could be a libtool bug with both libtool versions 1.5.6-4 and 1.5.10-1 -
what do you think? If you think it is a libtool bug, I'll raise one.
So in the meantime, we need this patch to compile lftp-3.0.13 for FC4 / RHEL-4 -
the objects produced seem to work fine:
