[Gambas-user] haw to call the "C or C++" function suma(a, b) from gambas?

[Adrian Martínez Vargas]

It really work very nice (better than visual basic), now I can do math in 
C++ static classes and GUIs with Gambas. The only that y see is missing is 
that Gambas be cross plataform (widows +linux +Unix, etc.)

EXTERN suma(A AS Single, B AS Single) AS Single IN "mylibrary.so:X"
' where X is the version number of the library.

PRINT suma(1.0, 2.0)

See the wiki documentation for more details.
