macOS How to build a dylib from a make file

[dbrayford]

I am trying to build a dynamic library file with the makefile below, but the libAGL.dylib created doesn't have any of the definitions from the source files according to nm libAGL.dylib | c++filt

What changes do I have to make to the file below to get it to create a valid library file?

Thanks
David
