GCC 4.x on SuSe 9.3 Pro Install/Compile

Dralnu · 03-21-2006, 12:27 AM

I'm not used to installing things from source, so I'll put everything here to get some help. The files that came with it are less then helpful. Doesn't make much sense to me (I got up to configuring. Anywho, here is my problem...

I've got an older version of GCC on my computer (3.2 I think). I downloaded GCC 4.1 because I need a library it has to run Wine 0.9.10, plus the upgrade might not be that bad. Anyways, I need either an faq for the installasion process, or pretty much a step-by-step walkthrough.

Thanks

BTW, the library I need is

thats the conflict.txt the YaST2 generated, so I figure that will help. In any case, thanks for the help

you might be better off installing wine from source instead of gcc-4. Try installing it to /opt/wine ( or build an rpm of your build, check out stuff like checkinstall for this ) and setting up your paths and you should be good to go. If you really want to upgrade gcc, in a terminal do:

Code:

gcc -v

that will give you the configure options used to build the compiler that you have now, it's a good idea to use the same or similar options if you are upgrading, and if you are installing it in /usr, I highly recommend building an rpm of your build and installing it instead of "make install".

Ok, that helps some, but how the heck does one build an rpm of it? I tried to uninstall the old gcc, but alot of the files that went with it, removing them could cause system problems (so says YaST2). I think I may have the rpmbuild tool on my comp somewhere (if not, its prolly on disk somewhere), and to explain my newbie-ness, I'm a fairly recent Whinedoze convert.

Thanks for the info

this is what I use, but there are other tools available. If you don't want to remove the old one (gcc), you can install the new one in /opt (something like /opt/gcc-4) and add /opt/gcc-4/lib to /etc/ld.so.conf and (as root) run ldconfig. If you want to use the new compiler instead of the 3.2 one, simply change your path to point to the new one before it hits the one in /usr/bin:

Code:

export PATH=/opt/gcc-4/bin:$PATH

this makes /opt/gcc-4/bin the very first directory searched for commands so gcc-4 will be picked up before the other one.
(if you just need the libstdc++.so.6 you will not need to alter your path for this, or even use the new compiler if you don't want to, just make sure you put the entry in /etc/ld.so.conf and run ldconfig).
