Instead of 'ifort' should we use the architecture triplet, eg. > i386-linux-intel instead ? > Then the libraries go in i386-linux-intel rather than i386-linux-gnu > for gfortran; > ditto for the .mod files in /usr/include/i386-linux-intel I'm not familiar with this i386-linux-intel triplet. Is this a triplet targeted by the toolchain? Does software built for this target not use GNU libc? (I guess I can't presume that it uses any libc at all, since we're speaking specifically of fortran here.)
