Hi community
I try to do a fast hack which shows me all the TCPIP Interfaces, their addresses (IP and HW) and their network masks.
Now I have a samll c-programm. I can compile it, but I cant link it.
The linker finds two undefined Symbols.
But as far as I can see, those two symbols are defined in sys$share:tcpip$libpcap_shr.exe and I use this shareable image for linking.
Can somebody give me a hint?
Please see attached files and output
Thanks in advance
Geni

Geni,
if I ANALYZE/IMAGE SYS$SHARE:TCPIP$LIBPCAP_SHR.EXE, I see "pcap_findalldevs" and "pcap_freealldevs", i.e. lower-case. You have to tell the C compiler to compile your modules /NAMES=AS_IS to pass them lower-cased to the linker.
HTH,
Martin
