Description Martin Mokrejš 2006-05-03 16:22:17 UTC
After recent upgrades I cannot compile some app. It turned out config.log contained:

/usr/bin/i686-pc-linux-gnu-cc -v
gcc-config error: /usr/bin/i686-pc-linux-gnu-cc wrapper: Unable to determine executable.

/usr/bin/i686-pc-linux-gnu-cc -V
gcc-config error: /usr/bin/i686-pc-linux-gnu-cc wrapper: Unable to determine executable.

compare with:

It seems the file is forgotten in place:

Comment 1 SpanKY gentoo-dev 2006-05-03 16:40:22 UTC
are you using eselect-compiler ?  gcc-config has never generated $CTARGET-cc afaik
Comment 2 Martin Mokrejš 2006-05-03 16:45:06 UTC
I have been using it, yes, I think because of mysql used to require that:

Comment 5 Jeremy Huddleston (RETIRED) gentoo-dev 2006-05-04 14:30:04 UTC
Martin, you don't even have eselect-compiler installed...
Comment 6 Martin Mokrejš 2006-05-04 14:33:25 UTC
Yes, I know, see comment #2. I did unmerge that. The question is why wasn't the file uninstalled? If there wouldn't be the mess with slotted mysql ... ;-)
Comment 7 Jeremy Huddleston (RETIRED) gentoo-dev 2006-05-05 11:09:53 UTC
1) because it's installed and managed by eselect-compiler, not portage.
2) mysql never required eselect-compiler
Comment 8 Martin Mokrejš 2006-05-05 12:21:27 UTC
Ok, but still, app-admin/eselect-compiler-2.0.0_rc1-r1 when was unistalled on Mar 01 should have deleted the file. I know, it is a masked package, at least now.
Comment 9 Jeremy Huddleston (RETIRED) gentoo-dev 2006-05-05 13:55:19 UTC
well, like you said, it's package.maskd becasue it's not ready to deploy.  Don't expect it to be flawless if you don't use it in its intended manner.  I'm hoping to have it ready this summer, but I haven't been as available to Gentoo lately.
