Hello Bill,

I don't think so because the comand below show that gcc and g++ exist like
this:
gelinp at gelinux:~$ gcc --version
gcc (GCC) 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)

gelinp at gelinux:~$ g++ --version
g++ (GCC) 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)
Copyright (C) 2006 Free Software Foundation, Inc.

By the way, when you say "Then set CC to gcc and CXX to g++" are you talking
about variables to set into .bashrc file or variable to set into the
CMakeList.txt file? I don't really understand that CmakeList.txt file
because I'm a newbe for cmake and I want only to compile a tool. I
used .configure, then make because that I know...

Thank you for your help.
