During a make world this morning (after cvsupping yesterday), my libc.so.3.1 somehow became corrupted (either something wonky happened to to break the source, or it got trashed during compilation or on disk afterwards, or something). Immediately after installing the new libc, make (which obviously uses that library) died with "undefined symbol: SYS_nlstat in libc.so.3.1" (paraphrased, but the standard message.) Naturally, this was something of a problem, since without libc I couldnt run ANY dynamic binaries at all :-) I ended up rebooting into win95, downloading the bin directory of a recent 3.0 snap onto another account, then extracting the libc file from there and installing it from single-user mode. Unfortunately I no longer have the corrupted libc.so file, in case that might have been useful (having deleted it without thinking :-( However I do have the libc.a, a search of which with strings shows: [morden|root] 23:39 ~/trash strings /usr/lib/libc.a | grep SYS [morden|root] 23:39 ~/trash strings libc.a | grep SYS SYS_nlstat SYS_nfstat SYS_nstat SYS_netbsd_msync SYS_lutimes SYS_netbsd_lchown SYS_lchmod SYS_getdents SYS_futimes (~/trash holds the corrupted version) I cant seem to find these symbols defined anywhere in the /usr/src/lib/libc tree - any ideas where they came from? Anyone want to take a look at the strange library? :-) I'm running softupdates on this partition - it's possible there was some kind of corruption there. On another another point: how difficult would it be to set up an uncompressed 3.0-SNAP tree somewhere (for disk space reasons, perhaps only the most recent "stable" version, or something) - so if someone happens to lose a major file, they can just walk in and grab the copy of the one they need, instead of having to trawl through 50M of bin.aa's. Alternatively, if there's an easier way to do the above, could someone point it out in case I'm in this situation again? Thanks, Kris WOWBO /\ . Through the darkness of future past, /\ .
