Thanks to Christian I compiled with success LAM on Mac OS X with IBM
compilers.
I tested different options in order to optimize the compilation.
In fact my old method with -O5 or -O4 flags produced errors with linker
and libutil.
This is strange in that case because the lib should be disabled with
the configure...
I succeeded finally with the following:
./configure --prefix="/usr/local/lam-7.1.1" --with-trillium
--disable-tv --disable-tv-queue --with-memory-manager=none
--with-rsh="/usr/bin/ssh -x" --with-fc=/opt/ibmcmp/xlf/8.1/bin/xlf
FFLAGS='-O3 -qextname -qstrict -qarch=auto -qtune=auto -qcache=auto'
CC=/opt/ibmcmp/vacpp/6.0/bin/xlc CFLAGS='-O3 -qstrict -qarch=auto
-qtune=auto -qcache=auto' CXX=/opt/ibmcmp/vacpp/6.0/bin/xlc++
CXXFLAGS='-O3 -qstrict -qarch=auto -qtune=auto -qcache=auto'
Do you have any suggestions?
Cheers,
Eric.
