The error around halfway with shader compiling is due to not adding a null terminator to the shader source strings. You can fix this by adding:
+ “x00”

Computers with older gpus may need to set the opengl version to 3.3 in order to get things working, you can use this code before the call to createwindow:

sdl.GLSetAttribute(sdl.GL_CONTEXT_PROFILE_MASK, sdl.GL_CONTEXT_PROFILE_CORE) sdl.GLSetAttribute(sdl.GL_CONTEXT_MAJOR_VERSION, 3) sdl.GLSetAttribute(sdl.GL_CONTEXT_MINOR_VERSION, 3)
