What you have here is a Linux specific problem. The C language
doesn't define different systems or different libraries, and not
dynamic libraries at all.

At least two of the headers you including, <syslog.h> and <sqlite.h>,
are not standard C headers but are system-specific extensions.

You really need to ask this in a group like
news:comp.os.linux.development.apps. All your questions are system
specific, and none of them are actually C language issues.
