configure on linux

configure on linux

[John Guthrie]

zsh-3.0-pre2 compiles fine on linux, with a few warnings.  However, for the
past several releases, configure has always failed to successfully determine
that lstat is in fact on my system.  Here are the relevant lines from
config.log:

configure:2608: gcc -o conftest  -Wall -Wno-implicit -Wmissing-prototypes -O2 -D
DEBUG   conftest.c  -ltermcap 1>&5
configure:2594: warning: no previous prototype for `t'
/tmp/cca074981.o(.text+0x14): undefined reference to `lstat'

For the time being, I can always just change my config.h file after running
configure, but where would I look for a more permanent solution.  (I.e., should
I be looking in configure, or do I wnat to go to autoconf?)

It seems that you did not read Etc/MACHINES despite the note at the very
beginning of the README.  I quote the relevant part:

Linux:  If you are using an early minor version of libc 5, then a bug
        in the auto-configuration process may cause zsh to think that
        your system doesn't support the lstat function.  If the
        configure process reports that there is no lstat, edit
        config.h and change HAVE_LSTAT to 1.
        libc-5.2.18 or later does not have this problem.

Perhaps you use libc-5.0.9.  It is really time to upgrade now, especially
if you want to use Linux-2.0.  I think it is very unlikely that autoconf
will be fixed so if you do not want to upgrade your libc, manually editing
config.h seems to be the only solution.  As an alternative you may edit
config.cache and change ac_cv_func_lstat='no' to ac_cv_func_lstat='yes'.
Next time when configure finds this cache in the current directory it will
use the information provided there.

A case of RTFM.  I guess after having used zsh for so long on several different
machines, that you forget to look at those files every now and then.  Editing
the config.h worked.

Thanks.
