If I pass -XExceptionDetail, I don't get much more: trist...@aontic1:~$ ipy -X:ExceptionDetail IronPython 2.6.1 (2.6.10920.0) on .NET 2.0.50727.1433 Type "help", "copyright", "credits" or "license" for more information. >>> import ctypes cannot load library LoadLibrary at offset 0 in file:line:column <filename unknown>:0:0 dlopen at offset 0 in file:line:column <filename unknown>:0:0 Invoke at offset 0 in file:line:column <filename unknown>:0:0 at IronPython.Modules.CTypes.LoadLibrary (System.String library, Int32 mode) [0x00000] in <filename unknown>:0 at IronPython.Modules.CTypes.dlopen (System.String library, Int32 mode) [0x00000] in <filename unknown>:0 at (wrapper managed-to-native) System.Reflection.MonoMethod:InternalInvoke (System.Reflection.MonoMethod*,object,object[],System.Exception&) at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0 OSError: IronPython.Runtime.Exceptions.OSException: cannot load library at IronPython.Modules.CTypes.LoadLibrary (System.String library, Int32 mode) [0x00000] in <filename unknown>:0 at IronPython.Modules.CTypes.dlopen (System.String library, Int32 mode) [0x00000] in <filename unknown>:0 at (wrapper managed-to-native) System.Reflection.MonoMethod:InternalInvoke (System.Reflection.MonoMethod*,object,object[],System.Exception&) at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0 On Sun, May 30, 2010 at 6:24 PM, Dino Viehland <[email protected]> wrote: > On OS/X I believe you need to use Mono’s DllMap feature ( > http://www.mono-project.com/Config_DllMap) to map from the Linux library > name (libdl.so) to the Mac OS/X library which exports dlopen.
