Hi all

Today (28th July) I upgraded the FreeBSD sources
(/usr/src) using
cvsup and when try to compile a test C program I get
following:

echo 'main(){}' > dummy.c
cc dummy.c -v -Wl,--verbose

/usr/lib/libc.so: undefined reference to
`SYS_cpuset_getaffinity'
/usr/lib/libc.so: undefined reference to
`SYS_cpuset'
/usr/lib/libc.so: undefined reference to
`SYS_cpuset_setaffinity'
/usr/lib/libc.so: undefined reference to
`SYS_cpuset_getid'
/usr/lib/libc.so: undefined reference to
`SYS_cpuset_setid'
/usr/lib/libc.so: undefined reference to
`SYS_setfib'
collect2: ld returned 1 exit status

I can see in logs following programs compiled without
any error:
cpuset_getaffinity.S
cpuset.S
cpuset_setaffinity.S
cpuset_getid.S
cpuset_setid.S
setfib.S

What's gone wrong now? Am I in the middle of a
FreeBSD update? or have
I made some mistake? or multiple routing tables update
on 20080724
broken something? Any ideas?

Did you build and install the kernel first?


I have compiled and installed **only** following to a separate location:
- FreeBSD Headers
- lib/csu
- lib/libc
- lib/msun
- lib/libc_r

And tested with a simple script whether I can compile and link against new libs successfully before I can proceed with my project. That test, as mentioned in the original post, failed to link against the new C libraries. That is, it looks to me, the libc is now broken.

Of course, the system I'm running is old, uname -a shows May 25. I don't think I have to run the latest kernel for me to separately link against a different copy of libc, do I?

If there a fix or a patch, I can apply against the libc and let you guys know the result.
