Compile RoHC tool using CYGWIN

Hello,

> Is it possible to compile the tool using CYGWIN on Windows ?

I don't know. Not tested yet.

> Unfortunately ip.h is different from FreeBSD and I get the following errors when trying to build rohc.o :

The ip.h header file is not from FreeBSD at all. It is a private internal header file of the library. The error happens because the "iphdr" and "ip6_hdr" structures were not found. Do you have the netinet/ip.h and netinet/ip6.h header files on your system? Did they define the iphdr and ip6_hdr structures?

Hi Didier

Thank you for quick answer.

I think the main problem is that Cygwin does not use netinet/ip6.h. I tried to define
my own netinet/ip6.h including ip6_hdr, but I still run into compatibility issues.

Would you please let me know what your ip6_hdr struct from netinet/ip6.h looks like ?
Also I would need the code snippets for the definition of struct in6_addr.

This is what I tried to define:

istruct ip6_hdr {
       unsigned char ip6_priority:4;
       unsigned char ip6_version:4;
       unsigned int ip6_flow;
       unsigned short ip6_plen;
       unsigned char ip6_nxt;
       unsigned char ip6_hlim;
       struct in6_addr ip6_src;
       struct in6_addr ip6_dst;
     };

Thank you for your help !

Hello,

I opened bug #813128 for your problem. I attached the netinet/ip.h and netinet/ip6.h header files from my system to the bug.
