Now, things like that are the reason there is space for languages like python, although it is an interpreted language, thus much slower by nature; not to mention "compiler-providing" languages, like Haskell, FreePascal, golang, and many others.

Being a Fortran 90/95 programmer for many years, I never had such an issue, although I extensively used modules (think of it as Fortran's way to define classes - although it's not exactly the same and it's way more flexible than C++'s classes.)
Honestly, if the multimedia libraries I need to use had ports for a decent compiled language, I would just get rid of C++ once and for all...

Anyway, I finally decided to use the enum trick, as ntubski suggested. This is actually what it is suggested at the above link as well.

I used following linking sequence....is it correct

gcc helo.c -lopencl -L/usr/local/lib/ -I$M2S_ROOT/runtime/include -static -Wall

it is giving me error: collect2: ld returned 1 exit status
