Yes, Andric is quite right.

To take things right:
 - you install crosstool-NG some where. Let's say it's in /opt/ct-ng
   (of course, you are absolutely free to install where you want, but it's
    sane to follow some /standard/ ways)

 - you set your PATH to include the /bin directory of crosstool-NG:
   export PATH="${PATH}:/opt/ct-ng/bin"

 - you create a directory where you'll work in. Let's say it's in a sub-dir
   in your home:  mkdir "${HOME}/work"

 - you go in that directory, and run crosstool-NG from there:
    cd "${HOME}/work"
    ct-ng help  # Or any other action...

 - you configure crosstool-NG to build a toolchain to install somewhere,
   let's say in "${HOME}/x-tools/${CT_TARGET}"

So, don't confuse things: where crosstool-NG is installed, where it runs in,
and where the toolchains gets installed in (and run from).

I guess he speaks of a cross compiler. There seem to be confusion between
cpp and g++, the formet being the C preprocessor, while the latter being the
actual C++ compiler.

CentOS is not a distribution I tested crosstool-NG on. Any report is
welcome! :-)

I'm afraid there are no exhaustive list... :-(
