Question

I’ve tried to set up CUDA and XCode on my mac to work together, but it failed.
During the process I went to /usr/bin/ and type:

and typed > sudo rm gcc

then > sudo ln -s /opt/local/bin/gcc-4.2 gcc

I think I screwed up something because now when I type in

> gcc

into the terminal, it says

-bash: gcc: command not found

how do I fix it and make the default gcc 4.2?

Answer 1

try doing

sudo ln -s $(which gcc-4.2) gcc 

instead. This will find the version of gcc-4.2 you’ve installed and link the default gcc to it.
