These are all correct.

ECLiPSe expects the file in the process's "current directory".
Which one this is is not under ECLiPSe's control. If your main
program is started by some C++ development system, then god knows
where it chooses to start its processes in...

You could of course specify an absolute pathname to your ecl file, e.g.


(but note the generic ECLiPSe pathname syntax, see os_file_name/2)

This is probably a problem with symbol mangling in your compiler.
Different compilers use different conventions, it is very hard for
us to investigate this.
