[BusyBox] [BB-1.0pre5][Diet-CVS] Busybox vs. diet: multiple build failures

Thu Jan 15 14:23:10 UTC 2004

compiling the whole thing with glibc-2.3 headers/dietlibc using gcc-3.2.2:

ok, looking at glibc headers and defining caddr_t to char * in ifconfig.c...

hmm... the function in question just prints some potentially useful info, commenting out
its body...

apparently the definition is in /usr/include/netinet/ip_icmp.h, but...

#define __USE_BSD
#undef __NETINET_IP_ICMP_H

...doesn`t help. So what`s the problem? Nevermind, cut`n`paste...
(additionally defining u_char and icmp_ra_addr).

Nice. Killing the #error...

That led me to th final linking stage.

The missing symbols are:

daemon
dprintf
mempcpy
sigsetmask
stpcpy
strchrnul
syscall

_and_ i was unable to find a useful __stdio_file definition to form a
meaningful SET_FERROR_UNLOCKED() macro for busybox.
