If a user changes GCC versions, but doesn't rebuild sudo, then commands executed via sudo will still use the old gcc version. It would be useful to mention this in the gcc-upgrade manual. The rebuild of sudo is a little tricky, since if you use sudo to do it, it will still get the old path. The easiest way to do it is: % sudo bash -l # emerge app-admin/sudo With the 'bash -l' giving a login shell, which will run the /etc/profile again. gentoo@brooks1.net 2006-06-23 19:13:58 0000 This issue is not a documentation issue -- there's a fix to this. The gcc wrapper that is provided by gcc-config checks $PATH in the user's environment first but will fall back and check /etc/env.d/05gcc if $PATH does not contain a gcc-bin path. See: /usr/portage/sys-devel/gcc-config/files/wrapper-1.4.7.c Since sudo is always configured --with-secure-path="$ROOTPATH", $ROOTPATH should have the gcc-bin stripped from it. I think it's pretty clear that since the gcc-bin path is specific to a compiler version, compiling it into sudo will necessarily result in a broken sudo. In my opinion the correct action is to strip gcc-bin from $PATH allowing the gcc wrapper to check the more up to date value in /etc/env.d/. I'm attaching a patch to sudo-1.6.8_p9-r2.ebuild which performs the above. This patch works on my system. gentoo@brooks1.net 2006-06-23 19:18:20 0000 Created an attachment (id=89971) Patch against sys-admin/sudo-1.6.8_p9-r2 removing ../gcc-bin/.. path elements nightmorph@gentoo.org 2006-06-24 08:40:42 0000 Not a documentation bug; reassigning. gentoo@brooks1.net 2006-06-28 19:36:58 0000 Created an attachment (id=90397) Patch against sys-admin/sudo-1.6.8_p9-r2 removing ../gcc-bin/.. path elements gentoo@brooks1.net 2006-08-02 17:17:59 0000 Is there anything happening with this bug? The current behavior of sudo breaks gcc-wrapper functionality, making it impossible to switch gcc profiles while using sudo. This should be fixed. The attached patch is sufficient to create the correct behavior. taviso@gentoo.org 2006-08-06 09:34:55 0000 p12-r1 in cvs fixes this issue, it's ~x86 currently but assuming everything goes well I'll file a stable request soon.
