C# mapscript not building correctly

[scottellington@…]

The c# mapscript module is not building correctly for me.  Here is the error:

scottell@arroyo ~/sandbox/mapserver-4.8.0-beta3/mapscript/csharp $ make
/usr/bin/swig -csharp -o mapscript_wrap.c ../mapscript.i

imageObj.cs(104,12): error CS1002: Expecting `;'

make: *** [mapscript_csharp] Error 1

This is on Gentoo Linux with mono 1.1.10 and swig-1.3.21.  Both 4.6.2 and 4.8.0 
are failing like this, but 4.6.0 builds fine.  I'm no expert on SWIG, but it
looks like it is creating bad code, the error above points to:

  public byte[] getBytes() {
    mapscriptPINVOKE.imageObj_getBytes(swigCPtr);
    return $modulePINVOKE.GetBytes();
}

This code should be compiled with SWIG-1.3.27 or SWIG-1.3.25.

Is the problem apply to these versions?

I will test this out when I am back from vacation on the 29th.

Ok. swig-1.3.25 worked for me.  It would be nice if a configure script could
catch that, or at least log that in the Makefile (or a README).

[szekerest]

I recommend to use the latest swig release since there were major changes in 
the C# generator.

Perhaps someone a bit more knowledgable than myself could author a README on
building mapscript for C#? I'd be willing to install it in the distribution.

Marking this as a WONTFIX for now.

Steve,

I have also experienced a gap in the C# topic. If I aim at writing this how to
make it available for the others?
