Ok, well the problem at hand is the following: |
| 14 |
|
| 15 |
from profiles/default-prefix/darwin/macos/10.4/x86/make.defaults: |
| 16 |
# set arch to prescott for all MacTel users, as this enables SSE and MMX |
| 17 |
# support in GCC |
| 18 |
CFLAGS="-march=prescott" |
| 19 |
|
| 20 |
That's just an incorrect default if you want to build x86_64 code, and |
| 21 |
should be nocona for a successful build. I remember this was added to |
| 22 |
the profile just because it was necessary to build certain applications |
| 23 |
correctly. |
| 24 |
|
| 25 |
I'm not sure what is the best/correct action to take here. |

Thanks for the information though! |
