[Mono-list] MonoDevelop GTK# and Pascal library

Fri Apr 22 12:03:08 EDT 2011

Hi,
I'm developing a library in Pascal and I'm testing it. I'm having no issues
on Lazarus, Delphi (Pascal) and SharpDevelop (C#) on Windows and Lazarus on
Kubuntu. But Running application created in MonoDevelop GTK# on Kubuntu
fails.

So I've created a simpliest library in pascal:
----------------------------------------------------
library libtmp2;
procedure testProc; stdcall;
begin
end;

exports
  testProc;
begin
end.
----------------------------------------------------
which exports one void function called testProc doing nothing.

And in MonoDevelop I've created class (the same way I've create id in
SharpDevelop for Windows)
public static class TestLib {

[DllImport("/home/bauglir/Desktop/Documents/Mono/Test1/Test1/bin/Debug/libproject1.so", 
      CallingConvention=CallingConvention.StdCall)]
  public static extern void testProc();
}

but calling 
TestLib.testProc(); 
fails:

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================

The application was terminated by a signal: SIGIOT

Does anyone have any idea what's wrong there?

Thanks
Brona
