external error

Hi,

i’m quite new in using opengl.I’ve tried but there’s some error message which stated ‘fatal error LNK1120: 1 unresolved externals’.
What should i troubleshoot here?

Thank you :slight_smile:

Sounds like you have a missing library, or are not linking the library in properly at compile time. You need to include the headers, which I suspect you are doing, as well as the libraries at Link time.

Are your OpenGL libraries referenced in your Linker settings for your project? From memory, you need to supply the path and the file name.
