Good to know.

This is not quite enough information.  Do you mean when creating a
program or creating a library?  Best to show the command (as you did
previously) and its output, then I can probably say how to fix it.

If you do './libtool --mode=link..', then this likely remains a libtool


No I don't think it's a libtool problem.   Basiclly  I call the AC_FC_LIBRARY_LDFLAGS macro to get the fortran  libraries to link with.   Due to the behavior of  pgf90, it either  puts the libso (for PIC code) first  or the lib directory first.  Both directories contain the same libraries just compiled differently.  So, I have to set LDFLAGS=-fpic before calling configure so that in the macro it passes the -fpic flags to pgcc/pgf90 and I get the libso directory first.  Autoconf doesn't use libtool to get that information.


LDLFAGS=-fpic ./configure
