SWIG C++ & gcc

[Morgan74]

Hello everybody,

I'm trying to compile a C++ extension for Sketchup using SWIG.
Thanks to Chris topic I have a working solution to compile C extension but PellesC don't handle c++ code.

So I moved to SWIG. I found this topic : http://forums.sketchucation.com/viewtopic.php?f=180&t=22109 but when I link the dll I still have some undefined references

Here is some errors :

obj\Release\example_wrap.o:example_wrap.cxx:(.text+0xd3): undefined reference to _imp__rb_eRuntimeError' obj\Release\example_wrap.o:example_wrap.cxx:(.text+0x113): undefined reference to _imp__rb_eRuntimeError'
....

for information I'm on a PC and I use mingw32-gcc.exe to compile and link.

Do you know a lib that I missed ?
