The main drawback to using C++ subroutine linkage in

sometimes even different compiler options. Exception handling is a
particularly thorny issue.
Please note that these problems are deadly to any proposal for a
standard plugin interface.
We can all hope that ABI instabilities will eventually become a thing
of the past, perhaps once GCC version 3 becomes widely adopted. But,
there is no proof that this will happen. Right now, the Linux world
is full of incompatible C++ compiler implementations.
Yes, this is the main problem, and I am aware of it (its bitten me
enough times..), must have slipped my mind before..
But I guess i'm living in the hope that gcc will settle on a stable ABI
in the not too distant future. I really dont understand why this hasnt
happened a lot earlier (although im no compiler guru) - its really vital
to building a successful platform i would have thought. This is the only
plus windows/macos etc have on their side..
are different versions of gcc3 ABI - compatible?
cheers
