Göran, I found your Syslog package, and was quick to lean toward the FFI form largely because when combined with Gnome's log file viewer and a filter, it will hopefully be similar to OutputDebugString + DebugView on Windows. I had to change the call to syslog: severity message: aString "private use void syslog(int, const char *, ...)" <cdecl: void 'syslog' ( long char* ) module: '/lib/libc.so.6'> ^self externalCallFailed You mentioned that your version might work only on your machine. Is there a correct way to do this that will be independent of the Linux distribution or libc version? Bill
