I have two users for whom a call to (gl:get-integer :num-extensions) errors with: OpenGL signaled (1280 . iNVLID-ENUM) from GET-INTGER-V
The only thing they both have in common it seems is OSX Here is copied from one of their slime error buffers.
OpenGL signalled (1280 . INVALID-ENUM) from GET-INTEGER-V. [Condition of type CL-OPENGL-BINDINGS:OPENGL- ERROR]
Restarts: 0: [CONTINUE] Continue 1: [RETRY] Retry SLIME REPL evaluation request. 2: [*ABORT] Return to SLIME's top level. 3: [ABORT] Abort thread (#<THREAD "repl-thread" RUNNING {1003448023}>)

It seems from here https://developer.apple.com/library/mac/releasenotes/general/macosxlionapidi... this enum was only added in OsX 10.7 (Lion) but at least one of these folks is using mavericks which has 4.2 support (so I'm told :))
Any idea what would be causing this?

I think :num-extensions requires a GL 3.0+ context, so in general you should check that before using it.

On OSX, I think you need to specifically request 3.0+ when creating the context, or it will only give you a 2.x context since it actually separates out the core profile. (On other platforms I think NVidia and AMD drivers will default to the highest version it supports, but enable the backwards compatibility extension or profile or whatever it is)
Fantastic, I will try this out tonight. Now I know what to google for the results all seem to be of the same opinion. Cheers
