Help installing gcc

[rebayona]

Hi, I just realized I didn't installed gcc when I first installed RedHat 7.1 on this server. I downloaded the latest gcc rpms, but as I'm a newbie here, I just ran the rpms, but nothing happened .... I installed gcc-2.96-81.src.rpm , gcc-2.96-85.i386.rpm , glibc-2.1.92-14.src.rpm and binutils-2.10.91.0.2-3.src.rpm. For what I see everything was OK, but I'm still unable to use gcc ... why? What am I missing here? Is it here, but do I hve to call it from its own path? Where is it?

Thank you guys,

Rafael

Hi,







Looks like you have mostly downloaded the source rpms (whatever.src.rpm) rather than the binaries (whatever.i386.rpm). That's a classic catch-22. You can't compile the compiler because you don't have a compiler & related utilities !







If you installed the binary gcc rpm you can see the files installed by the following command :







rpm -ql gcc (shows gcc is at /usr/bin/gcc)







That rpm has dependencies on 'binutils' and 'cpp' and 'glibc-devel' amongst others. So you'd need to install those too - in fact it wouldn't install without them unless you used the 'force' option.







As you've installed some source rpms you can test whether you have the compiler and tools properly installed by doing the following :







cd /usr/src/redhat/SPECS



rpm -bb --target=i686 binutils.spec







Assuming you changed nothing after you installed the binutils source rpm, that will invoke the compiler and build a binary RPM optimised for pentium class processors which will end up in the directory /usr/src/redhat/RPMS/i686 .







If you don't have all the bits then try installing all the .i386.rpms beginning with 'gcc' on your CD plus the 'binutils', 'cpp' and 'glibc-devel' ones.

Thanks a lot, it worked!

I just used the RPMs from the CD, since the ones (newer) I downloaded didn't work. Now I can use gcc!
