Miniupnp comes with a mingw makefile that works great for making the upnpc.exe. I would like to make a dll file to be used within my application. Does anybody know how to do this?

Here's where I've gotten so far. I installed MinGW and compiled all the sources:


Code:
gcc -c -Wall -Os -DNDEBUG -DWIN32 -DMINIUPNP_EXPORTS miniwget.c
gcc -c -Wall -Os -DNDEBUG -DWIN32 -DMINIUPNP_EXPORTS minixml.c
gcc -c -Wall -Os -DNDEBUG -DWIN32 -DMINIUPNP_EXPORTS igd_desc_parse.c
gcc -c -Wall -Os -DNDEBUG -DWIN32 -DMINIUPNP_EXPORTS minisoap.c
gcc -c -Wall -Os -DNDEBUG -DWIN32 -DMINIUPNP_EXPORTS miniupnpc.c
gcc -c -Wall -Os -DNDEBUG -DWIN32 -DMINIUPNP_EXPORTS upnpreplyparse.c
gcc -c -Wall -Os -DNDEBUG -DWIN32 -DMINIUPNP_EXPORTS upnpcommands.c
gcc -c -Wall -Os -DNDEBUG -DWIN32 -DMINIUPNP_EXPORTS upnperrors.c


This works fine, and produces all the *.o files. Then, I created a definition file miniupnp.def (not entirely sure if this was needed, but all the other mingw makefiles I found had one...)

Code:

LIBRARY
; mini upnp library

EXPORTS
; miniupnpc
    freeUPNPDevlist
    parserootdesc
    UPNP_GetValidIGD
   UPNP_GetIGDFromUrl
   GetUPNPUrls
   FreeUPNPUrls
; miniwget
   miniwget
   miniwget_getaddr
; upnpcommands
   UPNP_GetTotalBytesSent
   UPNP_GetTotalBytesReceived
   UPNP_GetTotalPacketsSent
   UPNP_GetTotalPacketsReceived
   UPNP_GetStatusInfo
   UPNP_GetConnectionTypeInfo
   UPNP_GetExternalIPAddress
   UPNP_GetLinkLayerMaxBitRates
   UPNP_AddPortMapping
   UPNP_DeletePortMapping
   UPNP_GetPortMappingNumberOfEntries
   UPNP_GetSpecificPortMappingEntry
   UPNP_GetGenericPortMappingEntry


And finally, I tried to link it all together. (This is the part that didn't work)

Code:
dllwrap -k --driver-name gcc --def miniupnp.def --output-def miniupnp.dll.def --implib libminiupnp.a -o miniupnp.dll -lws2_32 miniwget.o minixml.o igd_desc_parse.o minisoap.o miniupnpc.o upnpreplyparse.o upnpcommands.o upnperrors.o


Except I get the following error message:

Does anybody know how to fix this problem? Or how to make a miniupnp dll?

For reference, I'm typing this in on the windows command line.

I'd like to make a little library to make it easy to use miniupnp (and eventually nat-pmp) in C#. If I can get it working I'll release it to the public.

I figured it out. The "-lws2_32" part needs to go last. Like so:


Code:
dllwrap -k --driver-name gcc --def miniupnp.def --output-def miniupnp.dll.def --implib libminiupnp.a -o miniupnp.dll
miniwget.o minixml.o igd_desc_parse.o minisoap.o miniupnpc.o upnpreplyparse.o upnpcommands.o upnperrors.o -lws2_32

Thanks for the good job !
