compiling for OpenWRT MIPS

[danja]

getting this error and assuming that stdlib.h bundled with mips-uclibs is the reason:

mips-openwrt-linux-uclibc-gcc -Wl,-gc-sections -o hexinject hexinject.c -lpcap

any help anyone?

Hello,

seems an uClibc problem…

However I’ve tried to compile without stdlib.h:

In file included from hexinject.c:9:0:
hexstring.h: In function ‘hexstr_to_raw’:
hexstring.h:128:17: warning: incompatible implicit declaration of built-in function ‘malloc’
hexstring.h: In function ‘raw_to_hexstr’:
hexstring.h:171:20: warning: incompatible implicit declaration of built-in function ‘malloc’

But, as you can see, it gives a warning for the implicit declaration of ‘malloc’. It should works if you don’t care about the warnings…
Otherwise you can try to delete some headers from hexinject.h, and leave only:

#include "pcap.h"
#include "stdio.h"
#include "stdlib.h"
#include "stdint.h"
#include "getopt.h"
#include "assert.h"
#include "arpa/inet.h"

I don’t know how the compilation for openwrt is supposed to work, so it may be better to ask in openwrt forum/list…
