thanks heaps for that guy, it was some bogus header structures i had defined because I couldn't find the real ones...if anyone has copys of the structures for less used protocols like ipip, gre, idp, egp, pup and rsvp. as well as the structures for all the device types defined in ngrep (and i presume also tcpdump) I was able to find if_ether.h and if_fddi.h but none others, any help would be greatly appreciated!

In fact, I suspect it's a line before line 67 of "snoop.c", and if it's not line 66 there are probably only blank lines between it and line 67 - there might be multiple tokens before that line that are interpreted as data types, as C code such as double float int main(int argc, char **argv); int main(int argc, char **argv) { return 0; } gets the errors % gcc -c bong.c bong.c:1: two or more data types in declaration of `main' bong.c:1: two or more data types in declaration of `main' bong.c:5: conflicting types for `main' bong.c:1: previous declaration of `main' so you probably have something like that. It might be a missing character (a missing semicolon, for example), or an error at the end of a header file included just before line 67, or something such as that. - This is the TCPDUMP workers list.
