[Frama-c-discuss] GUI - Opening a file (Windows XP)

Hi,

I came across the same issue(Access Denied) while using a recent version 
of cygwin (1.7.7)
and frama-c binary Windows bundle Boron-20100401-Why 2.26.

The problem comes from cygwin and seems to be that /usr/bin/gcc is a 
symbolic link and not an actual file.

To solve it, either replace the /usr/bin/gcc symbolic link by its final 
target, which is
/usr/bin/gcc-4.exe on my system:

$ rm /usr/bin/gcc
$ cp /usr/bin/gcc-4.exe /usr/bin/gcc.exe

or use a custom frama-c -cpp-command (as Pascal suggested) :

$ frama-c -cpp-command "gcc-4.exe -C -E -I." first.c

No guarantee, but both these options worked for me. This issue seems 
related to
