I am currently trying to build the mosquitto-auth-plugin on windows but I am unsure which make process to use. The doc says to edit the config.mk file which I have done, then to 'make' the auth-plug -- this is were I am struck I have tried to make using GnWin & MinGW but neither has worked is there a way to build-make the library on windows or can I make it in Linux and copy the auth-plug.o to my windows machine?
I'm not aware of anybody having attempted to build mosquitto-auth-plug on Windows, and I'd be very surprised if that worked at all; as the author of the plugin, I paid no attention to portability outside Un*x, and so as to not raise hopes, I will not. :-)
That said, you cannot run (load) shared objects built on Linux on Windows. What may be possible, but it's been years since I did anything similar, is to cross compile with an appropriate toolchain.
