Pretty basic question, I'm trying to write a regex in Vim to match any phrase starting with `"abc "` preceeded by anything other than `"defg"`.
I've used `"[^defg]"` to match any single character other than d, e, f or g.
My first instinct was to try `/abc [^\(defg\)]` or `/abc [^\<defg\>]` but neither one of tho... |

crti.o is the bootstrap library, it should be found in /usr/lib. Your not cross-compiling are you? If your running a binary distribution they tend to put all the developer stuff into -dev packages (e.g. libc6-dev) as it's not needed to run compiled programs, just to build them. |
