Error connecting to Firebird 3, component TIBConnection (SOLVED) lazarus / 16-Databases ---------------------------------------------------------------------- Ame555 · 2020-11-29 22:27 Dear community, I am having problems trying to connect to firebird, I am using Lazarus V2.0.10 with the TIBConnection component, but when I connect it sends me the message "Can not load default Firebird clients ("libfbclient.so.2.5.1" or "libgds.so" or "libfbembed.so.2.5"). Check your installation" I am using Lubuntu 20.04. ---------------------------------------------------------------------- tonyw · 2020-11-30 14:24 It might have something to do with you using Firebird 3 and TIBConnection looking for the Firebird 2.5 client library or the Fiirebird 2.5 embedded server. I don't know why it would do that, IBX always looks for libfbclient.so or libfbclient.so.2 first and only looks for the legacy embedded server libfbembed.so or libfbembed.so.2.5 if neither are available. ---------------------------------------------------------------------- Ame555 · 2020-11-30 23:11 Hello, thanks to your answer I could find the solution, it was only necessary to create a symbolic link in my case this link. sudo ln -s libfbclient.so.3.0.5 libfbclient.so.2.5.1 Now it seems to be working well.
