    How did you install your gcc? Through a package of your distro or just by .tar.gz? What happens if you type
    Code:
    man gcc
    Do you get an
    Code:
    No manual entry for gcc
    If you install gcc through the package manager of you distro it should also install the manpages automatically. If you do it by hands you have to tell Linux to look into the correct path for the manpages. For example, I had ones an old intel compiler installed on my system. In order to see the manpages for the executables (compiler and so on) I had to write a manpage_map in the file /etc/man.config, which looked like
    Code:
    MANPATH_MAP    /opt/intel/compiler70/ia32/bin  /opt/intel/compiler70/man
    "/opt/intel/compiler70/ia32/bin" is the directory for the executables and "/opt/intel/compiler70/man" contains the manuals.

    Hope this helps,

    Hi, sorry for a very slow reply.
    I did install from packages with apt-get, however I do get the
    Code:
    No manual entry for gcc
    error when I attempt to do "man gcc".

    Can you posed your /etc/man.config file? Can you also check if you have the file "/usr/share/man/man1/gcc.1.gz"?

    I do not have "/usr/share/man/man1/gcc.1.gz".

    Your man.config looks perfect since you have this line
    Code:
    MANPATH_MAP	/usr/bin		/usr/share/man
    which means that your executables in /usr/bin have a manpage in /usr/share/man.
    However, what I still do not understand is that you do not have the
    "/usr/share/man/man1/gcc.1.gz" file because this is the manual for gcc and it should be
    installed with your gcc-package. I am not a debian expert. Perhaps you need to install the manual separately. Did you have these problems also with different programs?
    We can do three things. Either you try to find the gcc.1.gz anywhere in the internet and you just install it under /usr/share/man/man1 or I send it to you or SOMEBODY else knows how to install it in your debian distro.

    Cheers,
