Last week, when I am trying to install gcc_select on my macbook, I went through several commands,I did remember I just cd to a certain directory and made some modifications using the root. Everything seems fine, however, I found that when I open the terminal and trying to compile a program by using gcc or g++, it keeps saying that the “command not found”.I have to manually to type the :” export PATH=$PATH:/Developer/usr/bin” in order to make the gcc or g++ command run.
My question is , is there anyone please tell me how to permanently change that, so that I don’t need to type the same command again and again.
Append
in the .profile file in your home directory. If it does not exit, create it. Better way would be the one user57368 gave in the comment though.
