I've been thinking  about Using a library to handle the reports for CBT. Unfortunately I am not sure of how to write a library, and there is no wizard in Lazarus. I also am concerned with the fact that I don't want to install the library on the end-user's computer in the libs  directory, but leave it right with the executable. I've had problems figuring out the exe path before, especially when launched from a shortcut.

Paramstr(0) should return the correct binary executable.
You can check whether it is a symbolic link with stat() and S_ISLNK(),
and then follow the link with readlink(), this should produce the
correct binary name and hence directory.

Loading a library depends on whether it is statically (you must set
the LD_LIBRARY_PATH environment variable) or dynamically
(use dlopen() with complete path).
