Shared libraries

Hello

I try to create a shared library (named MySharedLib ) with PowerMops
5.5, using

***********

:entry  MyEntry  {  --  }
        10 beep 
;entry

************

and then to use it with:

************

library MySharedLib
libcall MyEntry {  -- }
MyEntry

************

I get:

Error # 220  Couldn't load shared library - see value system_err# for
error

system_err# .
-2804 

What is wrong? I have put MySharedLib in the same directory as
PowerMops (btw, what are the commands equivalent to chdir and dir in
PM?)

Labview does not find the entry MyEntry in MySharedLib either. 

Thanks for any help. May I have a working example?
