Replying to [ticket:8609 pulkomandy]:
> * The package manager may solve that in a better way ? (installing the
libs at the right place somehow ?)
With package management there will simply be two gcc4 packages: one for a
gcc4 Haiku, one for a gcc2 Haiku. As such this solution is not related to
package management. It could be implemented already, but would require
work on the build system, as well as building all the new packages --
which would have to be solved differently/have to be redone with package
management. So it isn't a particularly good investment of time ATM.
> * There is some work needed on build of packages, for example sdl-
config, allegro-config and other pkg-config files should look to setgcc
setting and use the right lib path according to that.
First of all, as you already said, the runtime loader should not allow
mixing shared objects for the two gcc versions. It should simply ignore
mismatching ones. The reason why it doesn't and why both paths are
searched is historical. It was necessary once, since we built C only
libraries only for one gcc and used them in all combinations. I think all
packages are available for both gccs now, so the runtime loader could be
adjusted accordingly.
We may also need to go further and use another library path variable for
the alternative gcc (like `LIBRARY_PATH_GCC4` on a gcc2h build). Further
path related changes (to gcc, cmake, pkg-config) may be necessary as well.
Save for the runtime loader related ones I'd put off the changes until
package management is ready.
