making old version of GCC your default compiler

knobby67 · 07-31-2006, 04:18 AM

Hello,
I've had a few problems compiling some code with debian etch which uses the GCC 4+ compiler. Code which worked great with the old GCC 3's. I've apt-get GCC version 3.3, but would like to know how to make this my default compiler, can anyone advise. Thanks in advance.

Hi

I'm using Sarge, not Etch, but on Sarge /usr/bin/gcc is just a symlink to gcc-3.3 so why not just change it to the gcc version you want?

Also, if the source has a proper configure script you can just set the CC/CXX environment variables to the gcc you want.

Just execute gcc-3.3 or gcc-3.4 from the command line instead of just gcc. (if you'd not like to tamper with the existing compiler sym links)

" ln -s gcc-3.2 gcc " can be used to make the gcc 3.2 ur default compiler.

I run Slackware, and I wanted to run multiple gccs because of Ada. I found that too many things got messed up when I tried to have more than one gcc installed, so I set up another userid and wrote a custom logon profile for bash that sets everything up like I want. All my normal users on that machine get the current gcc, and my special user gets his own environment.

If you have problems with paths and environment variables and you can't get it to work, maybe something like what I did will work for you.
