Throwing exceptions accross shared lib boundary

Throwing exceptions accross shared lib boundary

[Abhijit H. Bhosale]

Hi,
I am working on AIX 4.3.3.0.
Using gcc version 2.95.3 20010315 (release).
I am facing problem in case of
throwing exceptions accross shared lib boundary.
I want to know whether gcc 2.95.3 supports this or not.

We tried with gcc version 3.0.4
------------
Reading specs from 
/usr/local/gcc-3.0.4/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.0.4/specs
Configured with: ../gcc-3.0.4/configure --prefix=/usr/local/gcc-3.0.4 
--enable-threads=posix --enable-languages=c,c++ --disable-libgcj
Thread model: single
gcc version 3.0.4
------------
It works only if we link the libstdc++ dynamically instead of static 
linking.
Will the problem resolve by trying same thing with gcc - 2.95.3.

thanks
Abhijit.

	GCC 2.95.3 does not build libstdc++-v2 as a dynamic library.  GCC
2.95.3 also uses setjmp/longjmp for exceptions while GCC 3 uses Dwarf2
information on AIX. 

	You should upgrade to GCC 3.2 or possibly use GCC from the AIX
Toolbox for Linux if you really need libstdc++-v2.
