Yuck: Undefined symbol "__sbmaskrune"
I have saved tons of compile time in the past by using updated 6-STABLE binary packages, even though I'm running 6.2-RELEASE. (As discussed in past articles here and here.) Well, the last couple of days I gave some of that time back. :/ Packages grabbed from the '/packages-6-stable/' subdirectory are not running for me in 6.2-RELEASE. They would mostly exit immediately with an error message something like this:
/libexec/ld-elf.so.1: bash: Undefined symbol "__sbmaskrune"
Everything worked fine again when I reinstalled those ports by compiling instead of using packages. So, I've gotten all upgraded, it just took a little longer.
It's not really uncommon to have occasional little library problems with the binary packages. Usually that's a minor thing related to one of the dependencies and easily remedied, often by compiling it instead. I'm not sure what's going on in the above case. I'd guess something about system libraries changing in 6-STABLE and the upcoming 6.3.*
Also, I noticed that I'm not alone with this issue. I've seen a couple of related questions on the freebsd-questions mail list (search for "__sbmaskrune") and one of those involved system files. (Whereas, I sort of had the problem in reverse, having 6-STABLE packages that wouldn't run on 6.2.) It's a good time to remember that any STABLE branch is really a development branch and may have issues, however rare.
This sort of thing isn't supposed to happen, of course. "uunixuser" commenting at bsdforums.org pointed out this commit message which seems to be fixing and backing out the problem.
Just to clarify what the problem is(/was): There was a commit that changes some system libraries used by pretty much everything. So that ports compiled on 6-PRE-OOPS would no longer run on 6-OOPS, and vice-versa! My issue was I downloaded 6-OOPS packages and installed them on my 6.2 system. They wouldn't run. Most other people upgraded to 6-OOPS and then suddenly their old ports would not run. Now, the OOPS has been backed out and mappings for the OOPS library changes have been left in, so that a 6-POST-OOPS system should run packages built at any time. ... It's pretty damn confusing, I agree. :) But, the upshot is there's two ways to fix these ports issues: 1) recompile all of the ports. It doesn't matter what version you're on, recompiling will fix the port. (Reinstalling from a binary package may not.) 2) update your system to the latest 6-POST-OOPS. Again, should fix everything. (I haven't tested this myself, but reports are that it works.)
And, if you're having build issues this should help (from '/usr/src/UPDATING'):
A breakage was introduced in libc and fixed later. Make sure you have lib/Makefile rev 126.96.36.199. If it already breaks your world, you can recover it by
- reboot to single user mode, make sure you use /rescue/sh instead of /bin/sh
- use /rescue/chflags to remove schg flag on /lib/libc.so.6
- use /rescue/cp to copy libc.so.6 from /usr/obj to /lib/libc.so.6
- continue installworld, you should be fine now
