C++ compilation Problems

[Lukeson]

Hi

when I try to compile my main.cpp, I get this:

main.o: In function `main':

I do have #included "graphics.h" and the makefile contains OBJS = main.o graphics.o framebuffer.o

What do I do wrong?

Looks like you haven't linked in the libraries need for the graphics functions that you are using. Are you linking with gcc or g++?

[Lukeson]

gcc. The wierd thing is I defninitely have linked and included everything correctly. It seems that you can't use the C graphics.h libraries in C++...

[yaustar]

Yes you can. Again, are you linking with gcc or g++?

[Lukeson]

gcc

[yaustar]

If you are using C++ you MUST compile AND link with g++ NOT gcc.

Beyond the above error, your code/file structure is at fault. Host up ALL your code on to a server somewhere so people can download it.
