VC++.NET

[Michael Sgier]

Hi
i trying to port my OpenGL / C++ / SDL project to VC++.NET.
Why do i get those errors. The code compiles under Linux without
problems. I beliebe to have set correctly
the include and lib dirs also the headers.
Those errors do NOT make any sense at all.
THANKS and regards
Michael

You are using something like:
#if defined(something)
#endif defined(something)

You *must* change that to:

#if defined(something)
#endif // defined(something)

It would obviously help if you quoted the lines which cause the errors.
Is this so hard to do? Normally we see code without the error messages,
you've manged to do it the other way round.

I would guess that you have an error in the preprocessing directives in
the file mentioned, but without seeing the file it is difficult to
speculate what that might be.

Hello John
that's the whole file nothing cut out. I checked all files as world.h
is the last header file but still i couldn't find anything. Also i tried
to switch precomiling//precompiled headers on and off...no effect. I
copied those files to another working Ogl program ( without SDL ) and
got exactly the same errors....
THANKS
Michael

Avoid double underscores.

Nope that doesn't help. Still the same errors.

Not that long ago, i had some problems with preprocessor too. In my
case, what solved the problem is the newline after header-guard #endif.

Other than that, there could be problems in the other files that you
include (VC doesn't always report the right filename), so you might
want to check them too.

[Michael Sgier]

Hello
Nope no help so far...It must be some sort of alignment. I tried devCPP
and thatone only stops at several #include xxx without any details to
the errors. Really strange and timeconsuming aargh.
THANKS for further tips.

#endif

This is a strange error. Notice there are no #if/#endif pairs in that file.

I would try removing code until the error goes away. Last bit of code
removed will be the one causing the error. Start with the CWorld class
and then try each of the #includes in turn. If removing an #include
solves the problem then it's probably something in that header.

Could be one of the other include files has a #if and no corresponding
#endif, so the compiler only spots the problem when it runs out of input
and still has an open #if.

IIRC C++ forbids unbalanced #if/#endif or #ifdef/#endif within a single
file. So an error like that could be caught before leaving the file with
the unbalanced directives.

Another perennial is a missing '}' at the end of a class or namespace.
