Assuming that the soname of the library is libgpgme.so.0, yes. This is the name given after the -Wl,-soname,... parameter to gcc when the library is built; running 'objdump --private-headers' on the library file will also print the soname, and it's the name that appears when you run 'ldd' on programs that depend on the library. The .so link (libgpgme.so) should go in a separate -dev package along with the header files. This package should probably be named libgpgme-dev.

The old package sticks around, and things that depend on it don't break. So you have: -- Install libgpgme0_0.3.0-1, libgpgme-dev_0.3.0-1. -- Install myapp, depends on libgpgme0. -- Install libgpgme1_1.0.0-1, libgpgme-dev_1.0.0-1. At this point you still have myapp, which still depends on libgpgme0, which is still available. (libgpgme1 won't fill the dependency; since the library now has a different major version, its external interface has probably changed, so myapp would break if dynamically linked against it.) -- Rebuild and install myapp, now depends on libgpgme1. -- David Maze [EMAIL PROTECTED] http://people.debian.org/~dmaze/ "Theoretical politics is interesting.
