[Swig-user] Class/Namespace/C# problem

[Anders Backman]

Hi all, Im new to SWIG. Right now I'm deciding whether to use SWIG or CLI/C++ for wrapping a rather large C++ API into .NET (C#)

Im using SWIG 2.0.4 and Visual Studio 2010.

I stumbled on some quite irritating hurdles immediately.

I have tried to illustrate the problem in the attached code, it should build if you have swig.exe in the path.

I have basically two namespace's A and B (in reality I have a lot more, these are just very reduced examples to show two of my problems). 

One thing that sticks out is that there are two classes with the same name that exist both in namespace A and B.

My problems so far:

#1 the init function should be called as: A.init(); NOT A.A.init();

#2 A.Material does not exist in the generated binding code. Only B.Material

Command to generate binding:

swig -outdir generated -c++ -v -csharp -namespace A -Wall a.i

swig -outdir generated -c++ -v -csharp  -namespace B  -Wall b.i

runme.cs is using the generated code.

/A

Second attempt, seems that the SWIG list does not like html formatted
messages...

Have you looked at the nspace feature? Read the namespace section which
I'd guess you havn't yet come across:
