Linking library compiled with Forte and GCC!

Linking library compiled with Forte and GCC!

[Tan, Ryan]

Hello,

I am new to GCC community. I hope someone can help me.
Is it still true that there is no way I can link
the library compiled with different compilers?
I searched thru the mailing list and found one thread
from 1999.

My environment:
GCC 3.4.2 on Solaris 5.8.
Forte v6u2 C++ compiler.

I have a file (A.cc) using CNI to call Java class compiled in g++ 3.4.2.
I have other file (B.cc) that call the class in A.cc compiled using Forte
compiler.
I created the library (libA.a) from the above object files.

Now I created an application App.cc (compiled using Forte) that links the
libA.a
but got a link error with undefined symbol in B.o

I have compiled everything with GCC compiler that it works. I was wondering
if
I can use the Forte compiler since I don't want to limit the customer to use
the same compiler.

Thanks in advance!

Hello,

Yes, that's true. There is no standard as far as the
ABI is concerned so there is no way for a linker to
understand a C++ symbol generated by another compiler.
 
That's why commercial C++ libraries are provided with
the requirement to use a certain type of compiler (and
sometimes a certain range of version since the ABI can
change between versions of the same compiler).
