I saw these errors also yesterday, but did not find enough time to submit |
2 |
the comments yet :( |
3 |
|
4 |
I still had problems with the python-fchksum stuff and groff compiling. |
5 |
|
6 |
emerge python did the trick for the first thing and USE="-sandbox" emerge -e |
7 |
system did it for the second. |
8 |
|
9 |
Those commands were available in howto version 0.6, not in the 0.7. But |
10 |
they are still needed. |
11 |
|
12 |
For what package is the USE="-sandbox" needed? I thought sandbox was a |
13 |
FEATURE flag? |
14 |
|
15 |
I'm also working on a VIA epia M9000 system. What i would like to do is test |
16 |
the image (booting etc) on qemu before putting it on a compact flash. It |
17 |
would be nice if we could bring together some info on that part too (Or on |
18 |
other emulator soft). I will try to write it down while i work on this part |
19 |
and will post it here. If people already did this stuff, please post ;) |
