Somebody knows what I'm talking about ! Here is the extract from result of "nm DhcpCSvc.Lib" DHCPCSVC.DLL: 00000000 I .idata$4 00000000 I .idata$5 00000000 I .idata$6 00000000 T .text 00000000 T _DhcpCApiInitialize U __IMPORT_DESCRIPTOR_DHCPCSVC 00000000 I __imp__DhcpCApiInitialize What EXACTLY it is giving me ? Should I create a "DEF" file with all these name but with "_" in front of the name each function ? Or should I provide cygwin linker with some options to understand these kind of format ? And by the way, here is Makefile: -------------------------------------------------- CC = g++ CPPFLAGS = DEFS = INCS = LDFLAGS = ## Put them all together INCLUDES = $(INCS) -I. -I /usr/include/mingw DEFINES = $(DEFS) CFLAGS = $(INCLUDES) $(DEFINES) LIBS = -L. -L/usr/lib/win32api -liphlpapi -ldhcpcsvc .cpp.o: $(CC) $(CFLAGS) -c $< TARGETS = srv \ all: $(TARGETS) clean: -rm -f *.o $(TARGETS) *.1 srv: srv.o $(CC) -o $@ srv.o $(LDFLAGS) $(LIBS) Regards, Nickolai Bogdatov |---------+----------------------------> | | "lhall AT pop DOT ma DOT ult| | | ranet.com" >--------------------------------------------------------------------------------------------------------------| | | | To: Nickolai G.

The problem is not the import library (the .a you created has the same format as the .lib so there's no benefit to creating the .a). You need to find out if the function you're trying to link to is in that library and what it's name is. Run 'nm' on the library and grep the results for your function. If there's a function in the results that has the right name but has different stuff appended to the front and/or back, the include file you're using isn't giving you the right calling convention (cdecl, stdcall, fastcall). This is likely the problem.
