Frama-C is probably installed ok. Now the problem is that a
pre-processor is missing.

1) One solution, if you want to try Frama-C with small programs
written by yourself, is to name the files to analyse with .i
extensions, to indicate that they contain already pre-processed C
code. This way, Frama-C will not launch gcc to pre-process them.

The files must not use #include or #define.

2) You can install gcc in Windows, and make sure that the gcc command
is in your PATH. The recommended choice is MinGW: http://mingw.org/

You will know that you have installed gcc properly when you can type
"gcc -C -E first.c -o first.i" to generate a pre-processed version of
first.c in file first.i.

Good luck,

Pascal
