This patch fixes the names for other libraries as well. --- db_mysql.c | 8 ++++---- db_postgres.c | 8 ++++---- db_sqlite2.c | 11 ++++------- - dl_handle = dlopen("libmysqlclient.so", RTLD_LAZY); + dl_handle = dlopen("libmysqlclient.so.18", RTLD_LAZY); - dl_handle = dlopen("libpq.so", RTLD_LAZY); + dl_handle = dlopen("libpq.so.5", RTLD_LAZY); Not that easy. Probably needs to have a configure.ac replacement define there somehow, because distributions/distribution versions ship different versions of these libraries. You hardcode .18, but others may be at older versions still, or are at newer versions already (debian/ubuntu are .20 afaics). Similar with libpq. That was not a problem with sqlite3, there (currently) is only the .0 out there, so I was Same with sqlite2 (if someone really still wants to use that): - dl_handle = dlopen("libsqlite.so", RTLD_LAZY); + dl_handle = dlopen("libsqlite.so.0", RTLD_LAZY); But if "someone" was to fix the other instances, that should be fixed properly for sqlite2/3 as well. Note: csync2 with postgres and mysql would likely need a bit polish on the table creation, index definition and probably SQL queries in general to work "as intended" in all situations. Cheers, Lars
