[Gdal-dev] Re: Compiling swigged wrappers under MinGW

[Charlie Savage]

Ari,

Not sure if this is helpful anymore, but....

The trick with MingW I've found is link directly against the dlls.
Don't bother with dlltool and .lib files.

So:

g++ -shared somedll.dll my_code.o -o mydll.dll

I've had good luck with the Ruby bindings and MinGW.
