[Swig-user] Enrty point not found error...

[Chandra P. <cha...@ya...>]

Hi

When I use the following sample, I get the following
error in C#. Can someone please help.

Unhandled Exception:
System.EntryPointNotFoundException: Unable to find an
entry
 point named CSharp_CreateSquareBox in DLL example.
   at examplePINVOKE.CreateSquareBox(Int32 jarg1)
   at example.CreateSquareBox(Int32 width) in
C:\Projects\Phoenix\tools\src\swig
win-1.3.27\Examples\csharp\enum\example.cs:line 19
   at runme.Main() in
c:\projects\phoenix\tools\src\swigwin-1.3.27\examples\csha
rp\enum\runme.cs:line 31

But I was able to call getValue from C# that does not
have any Box parameters.

%module example

 %ignore Box; // The C# box class must be manually
created

 %typemap(in) Box %{ $1 = $input; %}
 %typemap(out, null="Box()") Box %{ $result = $1; %}

 %typemap(cstype) Box "Box"
 %typemap(imtype) Box "Box"
 %typemap(ctype) Box "Box"
 %typemap(csout, excode=SWIGEXCODE) Box {
     Box ret = $imcall;$excode
     return ret;
   }
 %typemap(csin) Box "$csinput"

 %inline %{
 struct Box {
   int width;
   int height;
   int length;
 };
 Box CreateSquareBox(int width) /*throw (int)*/ {
   Box b;
   b.width = width;
   b.height = width;
   b.length = width;
   return b;
 }
 int CalculateVolume(Box box) {
   return box.width * box.height * box.length;
 };

 int getValue()
 {
	return 5;
 }
 

 %}


I have the following C# class.

public struct Box
{
    public int width; 
    public int height;
    public int length;
}

Thanks
Chandra
