Or you could try -Wl,--export-all) For mingw32: -mdll tells driver to pass dllcrt2.o rather than crt2.o as startup object to ld and to use _DllMainCRTStartup@12 as entry point address. -shared does this too. -mdll passes --dll to ld. -shared passes -shared to ld. This is where the difference is: --dll only says: 'use default image base for dlls'. It doesn't do any of the relocatability magic. -shared says: "build a relocatable dll (or more generally, a shareable library)" ie, do all the things that dllwrap/dlltool would do You can (and probably should) override the default image base with ld switch, --image-base= xxxxxxx.
