R-devel now makes use of gcc4's visibility features: for an in-depth account see http://people.redhat.com/drepper/dsohowto.pdf (and note there are older versions of that document around). Consider for example stats.so. On a gcc4 Linux system this has just three entry points gannet% nm -g stats.so | grep " T " 00002720 T R_init_stats 0004a544 T _fini 00001f28 T _init since the only entry point we need is...

Your solution is correct, in that it will work and follows with the current ifdef approach. I applied this patch though, which doesn't use the ifdefs, hopefully it is more robust:

John, This was my attempt to add symbol versioning to the library, letting us break ABI without breaking any existing callers. Unfortunately it doesn't work: - the new versioned symbols are marked local in libguestfs.so - the existing symbols should now have @GUESTFS_0.0 versions, but don't The documentation for this stuff is extremely thin, and I've got a bad case of

This is a simpler patch series to add symbol versioning. I have pushed patches 1-3 upstream. Rich.

This rather more complex patch series adds symbol versioning (7/7 shows it in action). This works for me, tested by running old and new virt-inspector binaries against the new library. Rich.
