You seem to be using RHEL (version 5?). How did you install gcc?

Using yum install gcc works on my side of things.

On a RHEL 5.7 box:

my server is rhel 5.8. I install gcc when I install linux server.

my server is rhel 5.8. I install gcc when I install linux server.

There isn't that much of a difference between 5.7 and 5.8. Newer versions might be used, but that shouldn't be a problem.

Have you tried removing gcc and reinstalling it?

Getting a usable gcc : # yum install gcc-c++

I.e. the gcc-c++ dependencies glibc-devel, glibc-headers, etc.
will also provide full functionality for gcc.


-

leaving gcc installed on a server is not that good of an idea
reinstall it as needed .Then uninstall it when done


it is like leaving a bag full of "safe cracking tools" NEXT to your safe at work
-- it is begging for trouble

the shortcut "installing only gcc-c++ on 5 works
or the groupinstalls
but double check the spelling from
" yum grouplist"

how to remove gcc?

Post # 8.
You are not supposed to remove the default compiler !

And read post #6 :
gcc will not work unless you also install gcc-c++ ! !

Reinstall goes this way : # yum reinstall gcc

Besides that, the normal remove is : # yum remove <package>

-

1.I has installed gcc-gcc++.
2.use "yum remove [package]" will also remove dependency package.
3.if I just want to remove gcc.Can you help me?

yum remove gcc{,-c++}

There's nothing wrong with removing the compiler if you don't plan on compiling anything(It doesn't come standard on RHEL servers anyway) but don't be surprised when you get an error message that says "gcc not found".

I want to install oracle. gcc is needed?

Yes it's needed for installing oracle. It's also needed if you plan on keeping gcc-c++. The gcc-c++ package also only adds support for c++ so it' not needed for compiling C code.

could help me to solve this problem?

#yum install gcc*

try this
