Here's my output for the same command:

Quote:
$ rpm -qa | grep gcc
gcc-3.3.2-6mdk
gcc-c++-3.3.2-6mdk
gcc-cpp-3.3.2-6mdk
libgcc1-3.3.2-6mdk
Looks like you need the gcc-cpp package. I believe it's the preprocessor for gcc.

It may be under another package name in red hat. Try running:

# rpm -q --whatprovides gcc-cpp

That should list the package that provides gcc-cpp.

Also, check /usr/bin and see if gcc or g++ is listed. If not find out where they are located. It may not be in PATH. You can find out what files a given package has installed with:

# rpm -ql <package name>

That should list the location of the executable.

Edit: just noticed that you have "gcc-3.2.2-5" installed but don't seem to have a corresponding "gcc-c++-3.2.2-5" installed. Not sure what the "compat" packages do but they seem to provide a compatability layer for an earlier version of the compiler. The c++ compiler may not be installed at all. Try installing the "gcc-c++-3.2.2-5" package.

so you are saying i need to install the compiler?
i tried downloading 3.4.1 from the gcc site but i cant install that because when i go to configure it, it cant find the command "cc". also on the site it says there are links to binary files if you dont already have a compiler. but as far as i can tell there are none for redhat 9.
where do i go to get a compiler to install?
or is there one with the os that i havent noticed yet? is gcc even the command to compile a c++ program? or is it something else in redhat 9?
thanks if anyone can set me straight, i am getting myself so confused.

vanhelsing, for example here: ftp://ftp.redhat.com/pub/redhat/linu...6/RedHat/RPMS/

boom42k, you need to have a compiler before compiling a new one. You probably need to install it from a package. g++ is the command.
