On my fully-up-to-date F9 system, this file, junk.c:

int main ( int argc, char **argv ) { int x,y; struct in6_pktinfo junk; struct my_struct junk2;
x = sizeof (junk); y = sizeof (junk2); }
when compiled gives this error: $ gcc -c junk.c junk.c: In function ‘main’: junk.c:12: error: storage size of ‘junk’ isn’t known
Compile with gcc -D_GNU_SOURCE -c junk.c as struct in6_pktinfo is a GNU extension. info libc 'Feature Test Macros' for more info.
Thanks, that works. I had tried putting #define __USE_GNU in the code but that didn't make any difference. I downloaded the source rpm for dhcp-4.0.0 and the compile failed with this error. Packaging error or configure error?
Thanks, Steve
