Hello guys, I am learning OpenGL thru a book.It has a source code which works fine as it is. Recently i copied and pasted the same code to another new project, which is not working(I just wanted to mention that i have also written the same code myself, which is also not working with 9 errors :( ) I checked the path. Path has" /include" so it is right. This is the error- fatal error C1083: Cannot open include file: 'CGfxOpenGL.h': No such file or directory I created project "VC++ -> CLR application" is it the right way to do it? Its a "beginning opengl game programming" book.2nd chapter program "simple"

Start with a Win32 (non-console) project.

In the project configuration:

Add to "Additional Include Directories" the directory for your headers.
Add to "Additional Library Directories" the directory for your opengl lib file.
Add to "Additional (linker) Dependencies" your opengl lib file.

I think i solved that header file error

but now i m getting these errors -

Are you including a file with the implementation of CGfxOpenGL in your project?

It might be named CGfxOpenGL.cpp or similar.

ya, Project consist of CGfxOpenGL.cpp, trial.cpp, CGfxOpenGL.h.

Are you sure that the file is included in your project? It's not enough for it to just be sitting in the same directory as your other files - it must included in the project file listing, so it gets compiled and linked in. It doesn't currently seem like this is the case.

In MSVS, you generally do this by right-clicking the solution explorer pane, and choosing "Add > Existing Item".

If you're sure you've added the file, can you post the BuildLog.htm file referred to in your build messages? Use [source]..[/source] tags to keep it tidy.

I was also wondering the same thing, y the files are not being listed in the project.
Now this time i added new item(class), but i m getting error that i fail to understand. :(
