The solution seems to compile all the libraries you use with -
fvisibility=default or decorate all your source code with visibility
attributes, but this is no good if you're relying on third-party
libraries for which you don't have the source. I've managed to get my
warnings down to 10000 on every build, but build time is doubled by
the time it takes to print out all those messages. My actual solution
is to revert to Tiger for development, which also solves a host of
other linking problems, such as those associated with using libcurl,
and as a bonus I don't have kernel panics every half hour any more.

So this should answer your questions:

After upgrading from XCode 2.4.1 to 2.5 running on Leopard the
linker shows me thousands of "has different visibility" warnings.
(ld: warning __ZN13PWR_CStringRWC2ERKS_.eh has different visibility
(1) in /MyDev/LJS_DEV/app/trunk_build/debug/
libLJS_SQL_LIB.a(costcentre.o) and (2) in /MyDev/LJS_DEV/app/trunk/
xvt/mac/lib/libXVTPWRd.a(CTdiPackage.o))
Has someone already solved this one?
Thank you
Dieter
