Hi, I'm doing cross-platform development and I want to build a nice, self-contained (!) package for Linux. I know that that's not the way it's usually done, but the application requires all data in one place, so I'm installing it into /opt, like many other proprietary software packages do. I will eventually provide deb and rpm packages,...

From what I can see Gearman does not support scheduled jobs or delayed jobs. I was thinking that perhaps the scheduled job could be queued in at first and then added to the Gearman queue after the at time period has expired. at tasks are persistent as they are written as files to a directory in the spool directory of the server. So the ...
I have an application X which uses shared libraries A,B and C. Shared library C also uses some symbols from Shared library A. Application X is linked against A and B during compile time and it does dlopen to load C at run time. My question is Is it a good idea to link C against A during link time or leave the symbol resolution for run...
