I've already found that at link time -berok is used
So i replaced it and I've seen which function are unresolved at link time.
So corectly the -lglib-2.0 was missing.
I fixed it and it works fine now.

Do you Know if -lrtl is the same as -brtl at linking
And this option helps at run time af a program to find the shared libraries.
