Hi all, I am sorry for this newbie question I get this error messages when try to compile program in cygwin, but this program compiled successfully in Linux.
$ gcc-4 test.c test.c: In function 'main': test.c:152: error: invalid application of 'sizeof' to incomplete type 'struct iphdr' test.c:153: error: invalid application of 'sizeof' to incomplete type 'struct iphdr' My investigation show me that cygwin not have iphdr difinitions in netinet/ip.h like Linux. I use cygwin 1.5.25(0.156/4/2), so maybe someone in this list can explain to me how to workaround this. -- It is easy to say no when there is a deeper yes burning within -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
