Hello,

How can i cross compile libnatpmp for windows(libnatpmp.dll) under Ubuntu 14.04.
I have installed mingw32 and mingw-w64 packages.

Actually i made unsuccessful attempt:)

I made minor changes in Makefile
OS = $(shell uname -s) -> OS = WINDOWS
but i got error:

# make all
i686-w64-mingw32-gcc -shared -Wl,-soname, -o natpmp.dll natpmp.o getgateway.o -lws2_32 -lIphlpapi -Wl,--no-undefined -Wl,--enable-runtime-pseudo-reloc --Wl,kill-at
i686-w64-mingw32-gcc: error: unrecognized command line option ‘--Wl,kill-at’
make: *** [natpmp.dll] Error 1


After that i remove --Wl,kill-at and change flag -lIphlpapi to -liphlpapi
EXTRA_LD = -lws2_32 -liphlpapi -Wl,--no-undefined -Wl,--enable-runtime-pseudo-reloc

but still getting errors from linker

#make all
i686-w64-mingw32-gcc -shared -Wl,-soname, -o natpmp.dll natpmp.o getgateway.o -lws2_32 -liphlpapi -Wl,--no-undefined -Wl,--enable-runtime-pseudo-reloc

collect2: error: ld returned 1 exit status

Any suggestions?
Thanks
