Hello,

I am using the GNAT GPL 2007.1 version on a Vista machine.

After this I installed the win32Ada 2007 bindings.

When I tried to build the examples, I am getting al lot of warnings:

Must I do something more before it will work? Or...??? How can I check
that the automatic configuration worked well?

And were is the help file of the win32 binding, could not find that
either.

Thanks in advance.

Greetings Antoine

I have found the problem, during the automatic coniguration of
win32Ada there was a warning about missing stdio.h.

Therefor I set an environment variable C_INCLUDE_PATH to C:\GNAT
\2007\PENTIUM-MINGW32MSV\INCLUDE;C:\GNAT\2007\LIB\GCC\PENTIUM-
MINGW32MSV\4.1.3

Now the building went good and I can build and run the win32Ada
examples.

PS don't forget to put %PATH% in the PATH environment, otherwise
running the executables in an external window will not work. (missing
cmd)

PS I installed the GNAT GPL 2007.2 version now, but the problem is in
both of them. Tonight I will reinstall the latest version on my XP
machine to see if it is the same behaviour.

Greetings Antoine
