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.
