Hi Walt, |
| 20 |
It isn't anything like fsck, etc. The machine is healthy in all |
| 21 |
other respects (that I know of and have tested) and everything is |
| 22 |
actually working. It's only the list option that's failing. eselect |
| 23 |
actually knows that binutils is set correctly. It just won't like it. |
| 24 |
|
| 25 |
c2stable ~ # eselect binutils show |
| 26 |
x86_64-pc-linux-gnu-2.21.1 |
| 27 |
c2stable ~ # eselect binutils set x86_64-pc-linux-gnu-2.21.1 |
| 28 |
!!! Error: Profile "x86_64-pc-linux-gnu-2.21.1" is already active! |
| 29 |
exiting |
| 30 |
c2stable ~ # eselect binutils list |
| 31 |
!!! Error: Pattern does not match any installed version of binutils! |
| 32 |
exiting |
| 33 |
c2stable ~ # |

Actually, I don't think it's that hard to compare files or |
| 36 |
directories that are supposed to be consistent on various machines. |
| 37 |
That's what rsync does to decide what to sync. The trick is getting |
| 38 |
the options correct which is usually my downfall. |
| 39 |
|
| 40 |
Anyway, in this case I compare the /usr/share/eselect/modules |
| 41 |
directory on my local (failing) machine with one of the other machines |
| 42 |
here in the house. In the first compare I look at the binutils file |
| 43 |
specifically which passes. In the second compare I look at everything |
| 44 |
in the modules directory which shows one mismatch which in this case |
| 45 |
is that the remote machine doesn't actually have a wxwidgets.eselect |
| 46 |
file. I cannot tell that until I log into the remote machine to |
| 47 |
determine the difference. |

A little bit of Google suggests you can diff the files themselves |
| 67 |
using something like: |
| 68 |
|
| 69 |
diff <(ssh -n me@testserver cat /home/me/source/worksforme.php) <(ssh |
| 70 |
-n me@clientserver cat /home/me/source/worksforme.php) |
| 71 |
|
| 72 |
I have not tested this but suspect it probably works fine once you get |
| 73 |
everything right. |
| 74 |
|
| 75 |
HTH you or someone in the future, |
| 76 |
Mark |
