OpenGL OS/X, Linux problems

Newbie & Debugging Questions
#1

Hey guys. I finished my first Ludum Dare entry on Sunday and got some problems with cross-platform support. Everything runs fine on Windows machines but it seems to crash on start-up on Mac and Linux. The first problem was that I worked with Java 1.7 but in the meantime I switched to 1.6. I’m using LWJGL and OpenGL 3.2.

Since I don’t own a Mac or have a Linux system it’s quite hard to find the problem. But through people posting about the crashes it seem to be this part of the code where the error occurs:

int shaderHandle = GL20.glCreateShader(shaderType);

if (shaderHandle != 0) {
	GL20.glShaderSource(shaderHandle, shaderSource);
	GL20.glCompileShader(shaderHandle);
	int compileStatus = GL20.glGetShaderi(shaderHandle, GL20.GL_COMPILE_STATUS);
	
	if (compileStatus == 0) {
		System.out.println("Error compiling shader: GL20.glGetShaderInfoLog(shaderHandle)");
		GL20.glDeleteShader(shaderHandle);
		shaderHandle = 0;
	}
}

if (shaderHandle == 0) {			
	throw new RuntimeException("Error creating shader.");
}

“GL20.glCreateShader(shaderType)” seems to fail and returns 0.

This is how I’m initiating OpenGL on start-up:

PixelFormat pixelFormat = new PixelFormat();
ContextAttribs contextAtrributes = new ContextAttribs(3, 2).withForwardCompatible(true).withProfileCore(true);

try {
	Display.setDisplayMode(new DisplayMode(RESOLUTION.width,RESOLUTION.height));
	Display.setTitle(WINDOW_TITLE);
	Display.create(pixelFormat, contextAtrributes);
} catch (LWJGLException e) {
	e.printStackTrace();
	System.exit(-1);
}

Any ideas how to handle this and/or how to approach cross platform games?
