Hello Nish, Thanks for taking the time to send me a personal note. After more research, I agree 100% with you that it is not related to stripping the binaries. I deduce from Hiroaki's analysis that the problem is that the addresses in the shared object that are exported are modified with the -Bsymbolic-functions from what Bacula expects. While setting the default values of directives, Bacula compares addresses of function pointers. If these function pointers are changed from what Bacula expects, setting the default value fails. Bacula does not use position independent executables (at least we do not set it in our LDFLAGS).
In a future version (hopefully the next one), I will identify the function pointers with a unique index for each function, then instead of comparing function pointers, I will compare indexes. This will definitively avoid the problem. Thanks for making the Ubuntu build work again. On a different issue: If you would like, I will be happy to look at your patch for [Bug 1570923] Re: bacula-dir won't start with "undefined symbol: mysql_init", however, I don't know where to find it.
