Thread: libedit on OS X?
Hello. Is it possible to compile postgresql-7.4 on Mac OS X with libedit? Mac OS X Panther has libedit, but postgresql configure script complains about missing readline. - Tore.

configure looks for libedit too; that case allegedly works on some BSD
variants. Do you have a complete installation of libedit (headers as
well as library)? If so, let's see the full trace of configure probing
for this feature ...

I am running a standard Mac OS X Panther with developer tools and the
10.3.1 update.

checking for readline... no
configure: error: readline library not found
If you have readline already installed, see config.log for details on
the
failure. It is possible the compiler isn't looking in the proper
directory.
Use --without-readline to disable readline support.
I have not included the huge config.log, but it can be viewed at this
URL:
http://www.pvv.ntnu.no/~halset/tmp/20031207-config.log
It tries to link with readline, doesnt find that and tries once more
with libedit. ld report that _readline are undefined. /
- Tore.
Also, I am thinking we might just ship libedit with PostgreSQL in 7.5 and get rid of the readline dependency. --------------------------------------------------------------------------- Tore Halset wrote: > On Dec 7, 2003, at 21:06, Tom Lane wrote: > > > configure looks for libedit too; that case allegedly works on some BSD > > variants.

You are? Considering that most of the world has readline, that seems
like a fairly unnecessary bloat of our distribution.
I'm not sure why Tore's case is failing when libedit is reputed to work
for other people ... but I think we ought to find out and fix it, not
offer a brute-force solution of including someone else's library in
our distro.

I thought we felt libreadline was too fluid an API, and that the GPL zealots were saying dynamic linking was a violation of the GPL and would make PostgreSQL GPL too. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073

I fired up my beta copy of Panther and looked at libedit. It doesn't
seem to export any of the symbols required to be a plausible readline
substitute --- no readline(), none of the rl_xxx variables, etc. Nor
are any of the associated header files present.
So, no, you can't use this instead of readline. I'm a bit confused
why not though, since other people claim to have working configurations
like that. Perhaps what Apple is shipping is an ancient, un-featureful
version of libedit? Or something unrelated that happens to have the
same name?

That's my guess. libedit is a pretty generic name. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073

NetBSD has added an explicit readline compatibility layer to its libedit. I think that has spread around to some other BSDs, but apparently not far enough.
