Re: gstep-base changes for MinGW/Windows

Hi Adam,

I'll send you my latest make pkg in a separate mail.

Nice. Did you use Cygwin as the build environment, or Linux, or
MinGW-make ?

Make sure that the DLL is in $PATH, a DLL is like an .exe and has no
separate LD_LIBRARY_PATH like in Linux.

Also make sure that your .def file contains all ObjC-classes, so that
they are properly exported. The dllwrap-autogenerated .def files do not
contain ObjC classes, but only functions. You can check
'derived_src/mylib.def' for what is exported.
Maybe I should write a gen-def script which scans all libname_OBJC_FILES
for '@implementation' sections and outputs them into a .def file.
Notably with bundles you do not need .def files since all class-access
is done using the ObjC runtime.

You can also use the 'Quickview' context menu in the Filebrowser to see
what a DLL imports and exports.

Greetings,
