I finally installed a web browser on the target computer, and |
| 8 |
so can (just for the history:) copy and paste the result of running |
| 9 |
this and other commands on the target computer. |
| 10 |
|
| 11 |
# gcc -c -Q -march=native --help=target | grep march= |
| 12 |
-march=core2 |
| 13 |
So, you were right about core2 |

So, mmxext flag is indeed absent here. |

|
| 48 |
I have not yet included it in CPU_FLAGS_X86 and think that |
| 49 |
it produces a strange error messages when I try emerge some |
| 50 |
packages like firefox: |

|

# emerge firefox |

These are the packages that would be merged, in order: |
