Hi I want to port my MS VC++ game to Dev-C++ what changes do I have to make? Is there any sites/tutorials that can help me? Thanks.

try making a new project (or whatever) in DevC++, add all the files and compile. it gives you an error? fix it. doesn''t seem to be hard. it''s even possible you won''t get any errors, so try it 1st!

Yes, just remember that they both compile the same kind of code: C/C++. There are a few minor quirks, but there are a few people around that use Dev-C++ primarily (myself included), so we should be able to help you through your problems.

Always add this to your code:
#ifndef CDS_FULLSCREEN
#define CDS_FULLSCREEN 4
#endif

The Dev-C++ IDE uses the mingw g++ 2.95.3 compiler.
g++ manuals are available at gcc.gnu.org.

Go there, and compare their implementation of the language with Microsoft''s.

If you''re using Microsoft''s extensions to C++, be warned that you may have to change your code.

Ok I''ve fixed all the basic problems, now I just get errors with these:

free(TextureImage->data);
and
rand()%60;

whats the Dev-C++ equivalents?
I''ve looked at gcc.gnu.org but I couldn''t find anything of any use.
Thanks.

The free and rand functions are in stdlib.h, are you including it?

BTW: You really shouldn''t use modulo to clamp random numbers, it affects the probability distribution. You can find information about this online, I''m sick of explaining it over and over again .

Excellent! thanks a lot guys,
just one more question :-S

It only works when I put the GLaux.dll file in the application path, otherwise a msgbox comes up saying it can''t find it, can u help with this please?

Cheers

Dev-C++ links the libraries statically, while Visual C++ links them dynamically (meaning the necessary functions are compiled into the .exe). For Dev-C++ programs, the .dll must be located on the computer. This is true for opengl32.dll and glu32.dll, but these are already located in the Windows/system folder. GLaux.dll is not, so you will need to send it out with any programs you create.

Better yet, get rid of the AUX library altogether. NeHe has code for loading TGA files, and "OpenGL Game Programming" has code for loading BMP and TGA files (without glaux). Or you can use an image library. Personally, I use DevIL, but then you''ll still run into the problem of including DLL''s with your EXE.

DLLs always have to be somewhere where your app can find them. This is not compiler-specific, it''s a Windows thing.

So, if your DLL is a system one like OpenGL32.dll or GLU32.dll, they should be in one of the Windows system dirs already. If not, you should put them in your app dir.

Actually, this is a compiler specific problem, like I originally said. Try compiling the same program (using glaux functions) in MSVC and Dev-C++ and you''ll see that one will run and the other will complain about not being able to find a DLL. This is due to how the compilers link to libraries.
