|
|
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
natpmp.o:natpmp.c.text+0x199): undefined reference to `natpmp_gettimeofday'
natpmp.o:natpmp.c.text+0x1f7): undefined reference to `natpmp_gettimeofday'
natpmp.o:natpmp.c.text+0x489): undefined reference to `_imp__readnatpmpresponse'
natpmp.o:natpmp.c.text+0x4ad): undefined reference to `natpmp_gettimeofday'
/usr/bin/i686-w64-mingw32-ld: natpmp.o: bad reloc address 0x0 in section `.rdata'
collect2: error: ld returned 1 exit status
make: *** [natpmp.dll] Error 1
Any suggestions?
Thanks |
