FreeBSD letsd.clear-code.com 7.0-CURRENT FreeBSD 7.0-CURRENT #0: Wed May 16 15:10:34 JST 2007 root@letsd.clear-code.com:/usr/obj/usr/src/sys/SCTP i386
>Description:
SCTP related function man pages (e.g. sctp_bindx(3)) say that you need to link libc to use SCTP function. But /lib/libc.so.7 doesn't include sctp_* symbols:
% strings /lib/libc.so.7 | grep sctp
% # no output
So I can't use sctp_* functions on FreeBSD.
libc.so should export sctp_* symbols like man pages say.
>How-To-Repeat:
sctp-test.c:
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
int
main(int argc, char **argv)
{
sctp_bindx(0, 0, 0, 0);
return 0;
}
I can't build sctp-test.c:
% cc sctp-test.c
/var/tmp//cctHYOM8.o(.text+0x25): In function `main':
: undefined reference to `sctp_bindx'
>Fix:
Add sctp_* related functions to src/lib/libc/net/Symbols.map like the attached patch.
