How do I fix my OpenGL shader compilation errors?

I'm getting compilation errors in my OpenGL shaders. What should I do?

First, check the error messages provided by the OpenGL compiler. They usually indicate the line number and type of error.

The error says 'syntax error near unexpected token'. What does that mean?

This typically means there's a typo or a missing semicolon in your shader code. Review the lines around the error.

I found a missing semicolon! But now I'm getting a different error about 'undeclared identifier'.

That means you're trying to use a variable that hasn't been defined. Make sure all variables are declared before use.

Thanks! I fixed that too. Now my shader compiles, but it doesn't render correctly.

Rendering issues can be due to incorrect shader logic or data being passed to the shader. Check your vertex attributes and uniform values.
