This is the thing which you need to do once before building rpms:

Install the core development tools using YUM. As root:

Next, create the building environment for your user. Fortunately, Fedora includes some neat utilities that greatly simplify this procedure. First, use YUM to install them (as root):

That’s it.

Now, provided that you have a SPEC file for your program, you can build the binary RPM package by issuing the command:

If you need to build the package for a different architecture, you can set the --target option, like in the example below:

Right...that's what the OP stated in their first post.
You need to create a .SPEC file, so you can use the rpmbuild command. You can find details here:
