Fix so-names for additional libraries

[krig]

Commit 36e738e fixed the name passed to dlopen for libsqlite3.so. This patch fixes the names for other libraries as well.

Hi Kristoffer,

Holiday season... LGTM, but let me have a closer look. Lars or me will merge/comment soon. If this does not happen till the end of the week, feel free to kick us.

Thanks, rck

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

Yeah, this is clearly not a proper fix, but we've had this patch laying around forever so I thought I should at least submit it for review :)
