[Mono-list] SWF & Winelib Q&A

[Kevin Jones]

Peter thanks for this.

After following the steps I still have the same problem. I get

Could not load winelib.exe.so
Unhandled Exception: System.TypeInitializationException: An exception
was thrown by the type initializer for System.Windows.Forms.Control --->
System.TypeInitializationException: An exception was thrown by the type
initializer for System.Windows.Forms.Win32 --->

if winelib.exe.so is not in /usr/lib

If I copy it to that directory I get:

Could not stat /nt (No such file or directory), ignoring drive E:
Could not stat /home/kevinj/.wine/${HOME} (No such file or directory),
ignoring drive F:
Warning: could not find wine config [Drive x] entry for current working
directory /home/kevinj/temp/winforms; starting in windows directory.
Warning: L"/usr/local/lib/winelib.exe.so" not accessible from a
configured DOS drive
Warning: L"/usr/local/lib/winelib.exe.so" not accessible from a
configured DOS drive
wine: cannot find '/usr/local/lib/winelib.exe.so'

and yes it is in /usr/local/lib.

Any help would be appreciated.

THanks,
