Use the convention described in the libtool documentation. There's no need for the SONAME to have anything to do with the source version number. If the source version is incremented, but binary compatibility is kept with older versions of the library, you don't want to have to change the soname, so it's better to keep them separate. Whether you want to start numbering the CURRENT as 0, 1, or 2, or whatever is up to you and makes no real difference. Eric
