installing alternative (older) gcc version RHEL

[mahuro]

Hi All,

I hope you can help me.

I am installing the quake4SDK on RHEL , it needs gcc-3.3 , but I have gcc 4.1 ..

How can I install an alternative gcc3.3, without getting rid of the newest one , and solely to get this program to compile ??? I know there is an "alternative" managing system , but don't know how it works ...

Thanks a lot !

I don't know about 3.3, but you can install gcc 3.4 (should be backward compatible) on RHEL/CentOS systems. Just use yum to install the packages: yum install 'compat-gcc-34*'
That will get you gcc, c++, and Fortran. If you just want the C and C++ compilers: yum install compat-gcc-34 compat-gcc-34-c++

Hi Bubberman,

Many thanks for your suggestion, actually the yum install worked well iin RHEL !! one more thing is :

I need to know where it got installed !! I have used locate, find,whereis ... but all I got is paths to docs.

I need to direct the application I am installing at compilation time like this:

export CC=/opt/gcc-3.4/bin/gcc

But I can not find it !!

The packages I installed are :

compat-gcc-34-c++.x86_64 0:3.4.6-4.1 compat-gcc-34-g77.x86_64 0:3.4.6-4.1 compat-libf2c-34.x86_64 0:3.4.6-4.1

Any suggestions ?

Mant thanks.

Hi Rubberman,

This is the error I get as the compiler can not find gcc-3.4: ( as I said it does not know where it is)

g++-3.4 -o build/debug/game/game/Actor.os -c -Wno-invalid-offsetof -fPIC -pipe -Wall -fmessage-length=0 -fvisibility=hidden -m32 -DQ4SDK -g -O1 -D_DEBUG -fno-strict-aliasing -DGAME_DLL game/Actor.cpp
sh: g++-3.4: command not found

[Rubberman]

The compatibility compilers are in /usr/bin, as in /usr/bin/gcc34, etc.

Anyway, try g++34, not g++3.4
