Question

I’m using cygwin to compile a network tool(iffinder).

After ./configure and make i have a problem that i guess is related to struct icmp. Where is the icmp struct in header files. I searched for it in cygwin header files, but i didn’t find anything.

How can i compile source codes which need icmp, in cygwin?

If it helps, you can find the source code of iffinder here

Note: I have ip_icmp.h in my cygwin’s header files.

Compile error:

iffinder.c:1059: warning: "struct icmp" declared inside parameter list

iffinder.c:1059: warning: its scope is only this definition or

declaration, which is probably not what you want iffinder.c: In

function `handle_icmp_error’: iffinder.c:1069: error: dereferencing

pointer to incomplete type

…

Answer 1

iffinder.c line 54 does #include <netinet/ip_icmp.h> – is this header file present on your system?
