The scrpage2 package gives a different approach for the same purpose. It’s documented in the KOMA-Script manual.
Btw. often there’s no need to download documentation when it’s already been installed with the distribution. Just use texdoc and type in the terminal

texdoc fancyhdr

To display the KOMA-Script manual including the scrpage2 documentation I would type

texdoc scrguien

Now I’m using TeX Live 2009, texdoc is working with aliases as well, so texdoc koma would already work with it.

Another approach is provided by the listings package:

\documentclass[a4paper,10pt]{article}
\usepackage{listings}
\lstset{language=C++}
\begin{document}
\begin{lstlisting}
#include
#include

int main()
{
std::cout << "Hallo Welt!" << std::endl;
}
\end{lstlisting}
\end{document}

This package provides a lot of features for typesetting source code, many languages are predefined.

Comment on C++ Numerical Libraries by Christian

Christian — Sat, 26 Sep 2009 22:12:28 +0000

some other C++ numerical Libraries that I know:
eigen
Boost uBlas ()
Blitz
POOMA
TNT
Lapack++
eigen seems quite promising (Includes fixed size and dynamic size Matrices and uses expression templates (like Armadilla, UBLas, Blitz,.. do)

For those who say ‘install f2c, gfortran, fort77 ….’

If this does the job for you then great.

However it is not a solution to every problem. F77 code was written for a variety of compilers on a variety of platforms. The legacy codebase is full of hacks, compiler specific extensions and the linking of C and fortran code is horrific. g77 is great in that it is forgiving and will handle most things (because it is really a c compiler).

E.g. http://www.globeclaritas.com/

I know the guys who develop this software – it compiles and links code at runtime (originally written on vax!). Took then 6 months to get it running using gfortran.

IMPORTANT ADDITION

When i gave my howto above I included creating a ‘g77′ symlink.

This was a BAAAAAD idea.

Configure scripts will search for the available f77 compilers and will choose g77 first. Eg. rebuilding a dpkg will result in it being compiled with g77. I guarantee this is not what debian/ubuntu developers intend. This is probably the reason g77 was dropped.

Leave it as g77-3.4. If you need a makefile to find g77 set the variables F77=g77-3.4 and/or FC=g77-3.4

You can speed x5 the compilation (on Ubuntu at least) by disabling test suite.
search for a line in rules.def
‘# run testsuite ‘
there will be a line below somewhere
‘with_check := yes’
change it to (free banana for the first correct guess)
‘with_check := no’
