[Orclib-devel] Fwd: trouble building the C++ example code

[vincent r. <vin...@gm...>]

Sure !

Il will add support for Clang  asap and also modify the code to work with
older versions of GCC.

This may take few days. I will probably have all done by next week !

I will let you known as soon as compatibility with CLang will be done (2 or
3 days)

Regards,

Vincent
