Two gcc at the same time? OO

[Guest Azru]

After 4 days of downloading and installing rpms I finally got rid of all dependencies, installed X and Qt libraries and ./configure`ed Kdevelop. I run make and got an internal compiler error. *depressed*

I thought that maybe I should upgrade the version of gcc to a more stable version and so this happened:

[root@localhost xlib]# rpm -ivh gcc4.0-4.0.0-0.1mdk.i586.rpm

I received a message that gcc4.0-4.0.0-0.1mdk.i586.rpm has been installed already.

[root@localhost xlib]# urpmi gcc4.0-4.0.0-0.1mdk.i586.rpm

-- it said everything is installed. I tried to check the version of gcc:

[root@localhost xlib]# gcc --version

gcc (GCC) 3.4.1 (Mandrakelinux 10.1 3.4.1-4mdk)

:unsure: And then what packages I have installed on my system:

[root@localhost xlib]# rpm - qa | grep gcc

gcc-cpp-3.4.1-4mdk

gcc4.0-4.0.0-0.1mdk

gcc-3.4.1-4mdk

gcc4.0-cpp-4.0.0-0.1mdk

gcc4.0-c++-4.0.0-0.1mdk

libgcc1-3.4.1-3mdk

Duh... two gcc`s? :o I want to have and run gcc4.0.0. What should I do to get rid of the older version and get the newest one working by default? Any help would be very apprecieated, Im trying to get this working for about 5 days already and have almost no hope left. Thanks in advance.

Just run update-alternatives --config gcc and follow the steps (as always read the man page before).

[root@paleo root]# update-alternatives --config gcc
                                                                             
There are 2 programs which provide `gcc'.
                                                                             
 Selection    Command
-----------------------------------------------
*+    1        /usr/bin/gcc-3.4.1
     2        /usr/bin/gcc-4.0.0
                                                                             
Enter to keep the default[*], or type selection number:

 

do the same with c++ and gpp links if you wish. Once gcc's link points to the right version of gcc, you can unisntall the rpm package you don't want (or just keep both versions of gcc installed)

Thanks a lot -- it worked. Still... this gave me nothing becouse, Im still getting the damn "internal compiler error" when trying to install Kdevelop even when using gcc4.0.0. But thanks anyway, I learned how to use update-alternatives so its not that bad...
