Could not find or load the firebird client library [JDBC272] #319

Commented by: @mrotteveel Paolo, do you have a specific reason for setting the security level to developers only? Is your Firebird installation from the Ubuntu repository, or is it the generic linux zip download from http://Firebirdsql.org? |
|
Commented by: Paolo (pcucchi) No specific reason. Firebird installation is the generic linux zip download. |

Commented by: @mrotteveel I managed to reproduce the issue on a VM with Oracle Java 7 update 7 and the generic-linux Firebird 2.5.1 CS from http://firebirdsql.org. setting: produces the following log. As far as I can tell from this output it is not looking for the libraries in the java.library.path |

Commented by: @mrotteveel I have found a solution: (NOTE: It might be sufficient to only symlink http://libfbclient.so, I didn't try that). This will create symbolic links to the firebird libraries in a folder that is in the ld.so.conf.d (this is also what the normal Firebird install from the Ubuntu repository does). Another solution would be to add the /opt/firebird/lib folder to a conf file in /etc/ld.so.conf.d/ I am not entirely sure, but I think using LD_LIBRARY_PATH will also work, but I think the solutions above are better. I guess that Oracle Java on linux only uses java.library.path for locating libraries loaded directly from Java, which is probably why loading the libraries first using System.loadLibrary() did work), and doesn't add java.library.path to the ld searchpath. So when a native library itself attempts to load another library, that fails. |

Commented by: @mrotteveel Just checked, only symlinking http://libfbclient.so into /usr/lib/x86_64-linux-gnu should be sufficient. |

Commented by: @mrotteveel For Jaybird 2.2.1 and 2.3 I will add additional instructions to the releasenotes. |

I've set library path to FirebirdCS-2.5.1.26351-0.amd64/buildroot/opt/firebird/lib/libfbclient.so or /opt/firebird/lib (after installing it) or /usr/lib64 but I always have "Could not find or load the firebird client library"
If I statically load library through System.loadlibrary() I've no error.
System.loadLibrary("icudata");
System.loadLibrary("icuuc");
System.loadLibrary("icui18n");
System.loadLibrary("ib_util");
System.loadLibrary("fbembed");
System.loadLibrary("fbclient");
What could be wrong?
My system properties:
Jaybird 2.2 (generic Linux download)
Java 1.7.0_06 64 bit downloaded from Oracle
OS: Ubuntu 12.04 64 bit
Command line option: -Djava.library.path=/opt/firebird/lib or /usr/lib64
Debugged with netbeans 7.2
Runtime error:
