Hi Alex,
the problem is usually that a libtool ignores the -m64 flag; in my
experience even if LDFLAGS include that flag. You can check that by
finding the corresponding libtool line that leads to the make error:
libtool --mode=link gcc -m64 -o ...
usually leads to something like
gcc -shared -o ...
i.e., the gcc command following the libtool line is missing the -m64
flag. The only way that I found to work around this is to edit libtool
directly after you ran configure.
Somewhere there is a line
compiler_flags=
Change this to
compiler_flags='-m64'
and then run "make".
This is from my experience with almost any software package that I try
to compile on a 64bit platform (in my case powerpc64). I have not
attempted to compile LAM yet, thus it is possible that this does not
apply to the libtool version distributed with LAM. Nevertheless, it
is worth a try.
Cheers,
Martin
