On my Linux platform, I have several versions of gcc
.
Under usr/bin
I have:
gcc34
gcc44
gcc
Here are some outputs:
$ gcc --version
gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-48)
$ gcc44 --version
gcc44 (GCC) 4.4.0 20090514 (Red Hat 4.4.0-6)
I need to use the 4.4 version of gcc
however the default seems to the 4.1 one.
I there a way to replace /usr/bin/gcc
and make gcc44
the default compiler not using a symlink to /usr/bin/gcc44
?
The reason why I can't use a symlink is because my code will have to be shipped in a RPM package using mock
. mock
creates a minimal linux installation from scratch and just install the specified dependencies before compiling my code in it. I cannot customize this "minimal installation".
Ideally, the perfect solution would be to install an official RPM package that replaces gcc
with gcc44
as the default compiler. Is there such a package ? Is this even possible/good ?
Additional information
I have to use SCons (a make
alternative) and it doesn't let me specify the binary to use for gcc
.
I will also accept any answer that will tell me how to specify the gcc
binary in my SConstruct
file.
