Thanks for your answer Alejandro, I still can't get it right though.
class MyClass { public: MyClass(); ~MyClass(); int getValue(); void setValue(int val); private: int value_; };
Try:
cc++ -shared -mno-cygwin -o mydll.dll mydll.cpp \ -Wl,--out-implib=mydll.lib \ -W1,--output-def=mydll.def \ -W1,--export-all-symbols \ -Wl,--enable-auto-import \ -Wl,--enable-auto-image-base \ -Wl,--compat-implib \ -Wl,--add-stdcall-alias \ -Wl,--enable-stdcall-fixup
Ok, the .def file then looks like this:
EXPORTS _ZN7MyClass8getValueEv @1 _ZN7MyClass8setValueEi @2 _ZN7MyClassC1Ev @3 _ZN7MyClassC2Ev @4 _ZN7MyClassD1Ev @5 _ZN7MyClassD2Ev @6
Yu should recycle recycle your def file. You see, it will contain a lot of unnecessary symbols, so... After you have obtained a def file above, edit it to include only the symbols you really need exported and include it in your project for future use. Then you can do:
I guess I don't have to edit this file
cc++ -shared -mno-cygwin -o mydll.dll mydll.cpp mydll.def \ -Wl,--out-implib=mydll.lib \ -Wl,--compat-implib \ -Wl,--enable-auto-import \ -Wl,--enable-auto-image-base \ -Wl,--add-stdcall-alias \ -Wl,--enable-stdcall-fixup
To obtain a well behaved dll and a (probably?) usable import library.
If the .dll and .lib file is correct I can't tell. When I try to link the .lib file with an MSVC executable it still can't find the references. I am not sure what to expect, should the lib, def and dll contain Cygwin decorated symbols (which is the case now) or the MSVC symbols? Or do I have to add any flags to the MSVC linker (compiler) to solve the name differences?
