Bug 482334 – net-wireless/iw-3.10 - ./version.sh version.c: fatal: No names found, cannot describe anything.

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Davide 2013-08-24 14:33:56 UTC]

When emerging net-wireless/iw-3.10, it looks like the script 'version.sh' causes an access violation for the file /.git/index.lock
I asked for help on the gentoo portage forums, and it was suggested that this could be a bug in the ebuild.

This seems to be more of a git problem whan iw.

Following up on the forum thread, I'll say the same thing as Hu - don't put a .git in your root folder.

Please try the suggestion he has $GIT_DIR, and see if that solves the issue.
If not, feel free to reopen.

[Comment 5 Florian Schmaus 2013-09-01 17:00:11 UTC]

IMO it is an problem of the build system of iw together with default git behavior. Luckily the fix is simple: Check if .git/ exists before calling any git commands in the build process. I have created and attached a patch, which I also send upstream.

The suggestion using $GIT_DIR is just a workaround. Why shouldn't we fix the root cause? And please don't let this lead into a discussion about having a git repository within the root folder. The fact that an ebuild creates a sandbox violation in certain situations should be sufficient.

check for .git

[Comment 7 Bjarke Istrup Pedersen (RETIRED) 2013-09-01 17:40:48 UTC]

I see your point - I have added your patch to 3.10-r1 :-)

Great, thank you!
