Re: Compiling nmap on Red Hat

[Rob Nicholls <robert () robnicholls co uk>]

I went for a Desktop installation of Centos 6.2 (effectively a 
rebranded RHEL) the other day, then added some additional packages for 
development, clients etc. and I was able to compile Nmap okay (equally, 
I've never had trouble with building Nmap on Fedora in the past).

A "yum install gcc" might progress things slightly for you, as IIRC g++ 
is part of gcc. You probably need to install several other client and 
development packages to get other parts of the Nmap project (e.g. 
Python) to work though.

Basically, you should be able to compile Nmap on Red Hat, you just need 
to make sure you have all the development packages you need if you want 
to compile anything (including other tools) on your host. An alternative 
might be to install a binary version if you just want the latest stable 
version of Nmap (and aren't compiling from SVN): 
http://nmap.org/dist/nmap-6.00-1.i386.rpm (I haven't tried this myself).
