Hi, I'm trying to compile some libraries of us which need Sybase dll. I found that this guy, Michael Peppler http://www.cygwin.com/ml/cygwin/2004-11/msg00955.html had the same problem, but his comments aren't enough for me to get rid of it. Linking against sybase dll is succesfull, but strangely execution fails, and a gdb session shows me it is during a call to a Sybase fonction, and not one we wrote (the parameters passed are OK). I found that It was better to link agains import libraries, which can be generated when one has .lib files. That's what I did, following the procedure described in http://www.cygwin.com/cygwin-ug-net/dll.html (Linking against DLL). My def file has reference to functions which end with @n where n is number so linking fails (same as Michael Peppler). I redefined _MSC_VER=800 and finally got as result : spg_sybase.o:spg_sybase.c:(.text+0xa50): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0xaa8): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0xb00): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0xb58): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0xbb0): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0xc68): more undefined references to [EMAIL PROTECTED] ' follow spg_sybase.o:spg_sybase.c:(.text+0xdf4): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0xe08): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0xe20): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0xe34): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0xe43): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0xe90): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0xf00): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0x1159): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0x11a9): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0x121f): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0x122e): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0x1268): undefined reference to `dbgetuserdata@ 4' spg_sybase.o:spg_sybase.c:(.text+0x12d4): undefined reference to `dbsetuserdata@ 8' spg_sybase.o:spg_sybase.c:(.text+0x130a): undefined reference to `dbgetuserdata@ 4' spg_sybase.o:spg_sybase.c:(.text+0x138f): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0x139e): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0x13d4): undefined reference to `dbgetuserdata@ 4' spg_sybase.o:spg_sybase.c:(.text+0x142d): undefined reference to `dbsetuserdata@ 8' spg_sybase.o:spg_sybase.c:(.text+0x148f): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0x149e): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0x14d4): undefined reference to `dbgetuserdata@ 4' spg_sybase.o:spg_sybase.c:(.text+0x152d): undefined reference to `dbsetuserdata@ 8' spg_sybase.o:spg_sybase.c:(.text+0x158c): undefined reference to [EMAIL PROTECTED]' spg_sybase.o:spg_sybase.c:(.text+0x16c2): undefined reference to `dbgetuserdata@ 4' spg_sybase.o:spg_sybase.c:(.text+0x1716): undefined reference to [EMAIL PROTECTED]' which I can't understand since I *think* (but may be wrong) my .a fil has same references, or have I got something wrong ? here is what an nm on my generated .a file outputs : diefs00270.o: 00000000 b .bss 00000000 d .data 00000000 i .idata$4 00000000 i .idata$5 00000000 i .idata$6 00000000 i .idata$7 00000000 t .text U __head_libsybdb_a 00000000 I [EMAIL PROTECTED] 00000000 T [EMAIL PROTECTED] diefs00269.o: 00000000 b .bss 00000000 d .data 00000000 i .idata$4 00000000 i .idata$5 00000000 i .idata$6 00000000 i .idata$7 00000000 t .text U __head_libsybdb_a 00000000 I [EMAIL PROTECTED] 00000000 T [EMAIL PROTECTED] diefs00268.o: 00000000 b .bss 00000000 d .data 00000000 i .idata$4 00000000 i .idata$5 00000000 i .idata$6 00000000 i .idata$7 00000000 t .text U __head_libsybdb_a 00000000 I [EMAIL PROTECTED] 00000000 T [EMAIL PROTECTED] any idea ?
