At first I thought it worked, after upgrading to binutils 2.2 (in my home directory) I've now been able to compile.

I can't seem to run anything though:
Code:

matt@sahand:tmp$ rm -f a.out; pgfortran -V test.f90 ; ./a.out

pgfortran 11.10-0 64-bit target on x86-64 Linux -tp bulldozer

PGF90/x86-64 Linux 11.10-0

Illegal instruction
matt@sahand:tmp$


where test.f90 is simply a print hello world.

I've ever re-run the makelocalrc while specifying with my version of gcc can be found, to ensure it's using 4.6

Hi khea_actua1,

I wonder if your version of CentOS doesn't support AVX/FMA yet. What version are you using?

I didn't see anything on the CentOS website indicating if they do or don't support AVX. The best I could find is the following post on http://old.nabble.com/Strange-error-td31749507.html from June 11, 2011:
Quote:
We have confirmed that AVX code won't run on CentOS 5.6. As Red Hat 6.1
(recently finalized) is meant to have full support for AVX, we
anticipate availability of CentOS 6.1. I guess 5.8 may have a degree of
AVX support.

I can't confirm the validity of the post, but if you have an older CentOS, it could be the cause of the error.
