Usage: gcc-config [options] [CC Profile]
|
||||||
|
Change the current cc/gcc profile, or give info about profiles.
|
||||||
|
|
||||||
|
Options:
|
||||||
|
-C, --nocolor Disable color output
|
||||||
|
-O, --use-old Use the old profile if one was selected.
|
||||||
|
-f, --force Make sure all config files are regenerated.
|
||||||
|
-P, --use-portage-chost Only set to given profile if its CHOST is the
|
||||||
|
same as that set for portage in /etc/make.conf
|
||||||
|
(or one of other portage config files...).
|
||||||
|
-c, --get-current-profile Print current used gcc profile.
|
||||||
|
-l, --list-profiles Print a list of available profiles.
|
||||||
|
-S, --split-profile Split profiles into their components
|
||||||
|
-E, --print-environ Print environment that can be used to setup the
|
||||||
|
current gcc profile, or a specified one.
|
||||||
|
-B, --get-bin-path Print path where binaries of the given/current
|
||||||
|
profile are located.
|
||||||
|
-L, --get-lib-path Print path where libraries of the given/current
|
||||||
|
profile are located.
|
||||||
|
-X, --get-stdcxx-incdir Print path where g++ include files of the
|
||||||
|
given/current profile are located.
|
||||||
|
|
||||||
|
Profile names are of the form: <CHOST>-<gcc version>
|
||||||
|
For example: i686-pc-linux-gnu-3.2.1
