How to specify a specific compiler version?

raid517 · 06-17-2006, 08:36 PM

Hi, I am trying to compile an app that isn't included in my disrto's repos. Unfortunately the app doesn't seem to be playing too well with GCC 4.0x.

Is there a way I can specify which compiler the app should use during compiling?

Do you have multiple versions of gcc installed? Knowing your distro would help a lot, you should put it in your profile so we can all see.

Code:

CC=/opt/gcc-3.3.6/bin/gcc make

You coujld use $CC to point to the compiler executable but depending on your distro etc, there are better ways.

I'm using Debian thanks. And if I don't have a suitable version of GCC installed - it is no hassle to install one.

It's just this specific version of GCC that the app doesn't seem to like.

Unfortunatley, you can only install multiple versions of GCC. There is no way for you to specify which version to use.

If the source uses a configure script just add CC=[gcc-version] to the end. E.g.
./configure CC=gcc-3.4

What?

Erm... I wasn't sure how... but I am pretty sure it can be done.

If your app dosen't come with a configure script the gcc command should be set in the Makefile anyway, just change that.

As I said, 99% of Makefiles will use the CC environment variable, use it too.
