Are HP aC++ A.03.63 and A.03.45 compatible?

[Sreenivasulu Gelle]

Hi,
We are using HP ANSI C++ B3910B A.03.45 to build some module and HP aCC A.3.63 to build some other module of one single product.
Do we get any compatibility issues by using this way?
Your earliest response is highly appreciated.
Thanks

You shouldn't. But there is one issue where the class layout is binary incompatible. But on A.03.63 it will give you this warning:
1039 Type %1$s has a configuration of non-virtual and virtual bases that generate a vtable layout that is binary incompatible with releases A.03.33 to A.03.50.
To generate a compatible layout for these releases use +abi_3_33_compat.

Hi Thanks a lot for your reply.
I would like to know compatibility issues b/w HP ANSI C++ B3910B A.03.39 and HP aCC A.3.63.

That link I mentioned the only compatibility issue I know of. Your new versions are on both sides of the "divide". So A.03.39 and A.03.45 would have no problems, even if both are "wrong".

But as long as you don't get warning 1039 when compiled with A.03.63, you don't have this problem.
