Обсуждение: -HEAD configure issue with libedit on linux
There seem to be a number of issues with our libedit support. One of them is that we fail to build on Linux (at least on Debian Etch/4.0 x86_64 and i386) if libedit-dev is installed but not libreadline5-dev. The problem is that in that configuration ./configure seems to think that there is a working strlcpy available due to the fact that it includes -ledit in the relevant configure test which seems to provide strlcpy :-( This results in a compile time failure as can be seen on: http://www.pgbuildfarm.org/cgi-bin/show_log.pl?nm=Shad&dt=2006-11-29%2019:39:31 It looks like emu is the only box on the buildfarm building with --with-libedit-preferred which might explain why we have not noticed that earlier.

Sorry I was cracked. Yes Ubuntu suffers from this (thanks to Stefan for pointing out my flaw in testing). J > > Joshua D.

I'm too tired to look into that in more detail today but it looks like we are not picking up libedit(which should be in the base installation there) on FreeBSD even with --with-libedit-preferred config.log available at: http://www.kaltenbrunner.cc/files/config.log Stefan

So I don't think this is a bug. regards, tom lane
