Description Don Lewis freebsd_committer freebsd_triage 2011-11-19 22:50:04 UTC 
	When attempting to build the math/atlas port on x86_64 hardware
	running a 32 bit kernel, userland, and ports, the atlas hardware
	probe detects that it is running on an x86_64 architecture CPU.
	The build then assumes that it should do a 64 bit build and falls
	over when gfortran rejects the -m64 option.  Strangely, it doesn't
	attempt this when compiling C code with gcc.

Fix: There is probably a way that the hardware probe could detect that
	the CPU is running in 32 bit mode on x86_64 hardware that could
	be added to the generic probe code.  The following patch just
	skips the generic probe so that the FreeBSD specific probe is
	executed instead.
How-To-Repeat: 
	Attempt to build the math/atlas port on x86_64 hardware running
	a 32 bit kernel and userland.

I'll take it.

Don:

Sorry about the delay in my response -- this port is intimately
connected with math/lapack, and we are just finishing making some
alterations to some of the other lapack-related ports -- soon
afterward, I'll try to fix this problem, although in a slightly
different way (by restoring the pointer width argument to the
configure script that was removed in the last revision of atlas),
since other architectures (e.g., powerpc/powerpc64) could also be
affected.

Regards,
                b.

Don:

Would you please check if the following patch solves your problem, and
inform me of the result?

The build seems to run way to quickly and exits here:
