How to install G++ compiler


I've just installed Fedora core 8 and I used the add/remove software feature to install GCC. Apparently, g++ is bundled into the gcc program. When I type in..

Code:
g++ -o hello_world
..I just get a bash command error saying "command not found". I'm kind of unsure as to where to go from here. If I've installed gcc, shouldn't g++ be there too?

Thanks for any help.

...it may be, I'm not too sure how Fedora bundles the GNU Compiler Collection (GCC).

(As an aside, keep in mind, the "-o [string]" option just sets the output binary name to [string] instead of "a.out" - you need to supply a third argument: "g++ -o hello_world hello_world.cpp".)

With Debian, the gcc package only installs the C compiler of the GNU Compiler Collection; the g++ package installs the C++ compiler. Check and see if there's a g++ package (or something similar) in the Add/Remove Programs utility (I think it's called "pirut").

I figured it out:

I just needed to type "yum install gcc-c++"

But now I'm confused about what yum is. Does Fedora have multiple package managers?

Pirut is a gui version of yum (or frontend - not quite sure which). Both use same mechanics as far as I can tell.

That said, I still prefer yum from the command line

I believe Pirut is a front-end to Yum (which is, in turn a front-end to rpm) which is much like in Debian where aptitude, synaptic and apt-get are front-ends to apt, which is a front-end to dpkg.
