Hi,

many distributions have something like a 'switch' command such that an
ordinary user can switch the version of his/her default gcc compiler.

Is there something similar in GenToo?

Many thanks for a hint,
Helmut.

Forgive previous post. Didn't read it properly. I'm not aware of any
user switching program but perhaps you can manually select your gcc
profile by using /usr/bin/gcc-x.x.x rather than gcc.

You could do something like the following:

# Set environment
eval $(gcc-conifg -E <profile>)

# Set library path
export LD_LIBRARY_PATH=$(gcc-config -L <profile)
