Hello, I am compiling Om from CVS on an opteron. I can compile fine
without sse optimization. However when I try to optimize I get an error
posted below. Any ideas? Thanks. -Garett
I am doing:
>./configure CFLAGS="-march=k8 -mfpmath=sse"
...
configure: Building with flags: -march=k8 -mfpmath=sse -DNDEBUG -DNDEBUG
-pipe -fmessage-length=139 -fdiagnostics-show-location=every-line
>make
