If your CPU is Sandy Bridge, please use Clang version 3.1 and above. The Clang 3.0 will generate the wrong AVX binary code of OpenBLAS.
You will need to install the following tools from the FreeBSD ports tree:
- lang/gcc [1]
- lang/perl5.12
- ftp/curl
- devel/gmake
- devel/patch
To compile run the command:
$ gmake CC=gcc46 FC=gfortran46
Note that you need to build with GNU make and manually specify the compiler, otherwhise gcc 4.2 from the base system would be used.
