I am trying to emerge nettop, but it gives me the following error... (Incidentally, I am using gcc 4.1)

same error here, it won't compile with gcc4.1 (gcc 3.x works).
It's quite simple to get rid of those compile errors, here's what you need to change:
nettop.c
| Code: |
/* insert this line somwhere on top to get rid of warnings like "implicit declaration of strxxx" */
#include <string.h>
/* line 219: ether.count = ether.size = (int) ether.l = (int) ether.r = 0; */
ether.count = ether.size = 0;
ether.l = ether.r = 0;
...
/* line 224: ip.count = ip.size = (int) ip.l = (int) ip.r = 0; */
ip.count = ip.size = 0;
ip.l = ip.r = 0;
...
/* line 229: tcp.count = tcp.size = (int) tcp.l = (int) tcp.r = 0; */
tcp.count = tcp.size = 0;
tcp.l = tcp.r = 0;
...
/* line 234: udp.count = udp.size = (int) udp.l = (int) udp.r = 0; */
udp.count = udp.size = 0;
udp.l = udp.r = 0;

I mean it's kind of creative to cast 2 pointers to an interger and then assign them to an unsigned int and an unsigned long long :D But unfortunately gcc 4.1 doesn't like it.
So I got nettop compiled but valgrind complains about some invalid reads and I got a segmentation fault, so I think there is more to be fixed. Don't have time right now, but I'll have a closer look next week. |
