 |
|
Yesterday I was solved usual problem with automake. There are different versions of automake and not all programs compiled successful with the latest one. For example emerge ddccontrol fails with automake 1.13.1.
I found advices like mask new version of automake or make a symlink -> /urs/bin/automake-1.12. Today I found that there is variable like WANT_AUTOMAKE.
So | Code: | | WANT_AUTOMAKE="1.12" emerge ddccontrol # solution |
The Question: how can I guess it? How can we know which ENV (in wide sence) variables program use?
For example, this:
| Code: | ltrace -f -s 10000 python /usr/bin/emerge ddccontrol 2>&1 | grep getenv | grep AUTOMAKE
ltrace -f -s 10000 python /usr/bin/emerge ddccontrol 2>&1 | grep AUTOMAKE
|
don't show anything. |

You can't guess it. Not really. The Gentoo Development Guide documents this variable as part of the autotools eclass. In other words, it's not the program's fault (or responsibility); it's the Portage tree's fault. If you have to set that variable on the command line to get something to emerge, then this is a bug and should be reported.

Please report bugs for these build breakages.

Why didn't I think of that?
