Hello, For your information, I have pushed a fix to both Branch-5.0, and Branch-5.1 on Source Forge that resolves the problem detecting multi-thread MySQL client libraries if no static libraries are present. This is probably not the definitive answer, but for moment, it should work at least on Linux systems. I am have not explicitly tested the patch on FreeBSD and Solaris, but according to the man pages, it should work. However, on the esoteric Unix systems (where we do not support the Director anyway) such as HPUX and AIX, it probably will not work, but will not make things worse.
Consequently, the current SF repo code should have no problem properly detecting MySQL and PostgreSQL for batch insert.

Does it make network security easier or more difficult to achieve? Read this whitepaper to separate the two and get a better understanding. http://p.sf.net/sfu/hp-phase2-d2d _______________________________________________ Bacula-devel mailing list Bacula-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-devel
