This document covers only the process of building K-Meleon's source code. For documentation on building a complete K-Meleon distribution, see BuildKMeleonDistribution.
All you need to do next is build k-meleon.exe and the plugins. This should be straightforward if you use Visual Studio.
If Visual Studio complains that it cannot find the Mozilla header files, go to Project > Settings > C/C+'+ > Preprocessor > Additional include directories (VS 6) or Project > Properties > C/C+'+ > General > Additional Include Directories (VS 2003) and correct the Mozilla directories.
You should also change the output directory, Project > Settings > Link > Output file name (VS 6) or Project > Settings > Linker > General > Output File (VS 2003).
