I have gcc 11 and 12 installed, while 12 is default. Is is possible to install specific package with gcc 11?

For permanent solution create a file

Code:

/etc/portage/env/gcc11.conf -->>
CC=/usr/bin/gcc-<version>
CXX=/usr/bin/g++-<version>

Then append to

Code:

echo "<full-name-of>/<package> gcc11.conf" >> /etc/portage/package.env

for on the go solution

Code:

eselect gcc list
eselect gcc set <index-of-11>

or

Code:

gcc-config --list-profiles
gcc-config <profile-index-11>

If using the on the go method please remember to revert back to gcc12.
