I installed gcc 4.6. from macports (for support of C++0x). But when I check the 'gcc --version` it is showing older version. How to use the newer gcc installed by macports?
You can control the symlink in /opt/local/bin/gcc
by using port select
. You can see available version using port select --list gcc
. Anything listed with mp- as prefix refers to MacPorts' own port, gcc42 and llvm-gcc42 refer to the compilers shipped with Xcode by Apple.
Example from my system:
$ port select --list gcc
Available versions for gcc:
gcc42
llvm-gcc42
mp-gcc45
none (active)
$ sudo port select --set gcc mp-gcc45
Password:
Selecting 'mp-gcc45' for 'gcc' succeeded. 'mp-gcc45' is now active.
After that, either open a new terminal window or issue hash -r
to make bash recognize the change.
