Subject: `configure --with-ns' fails when the shell is not bash
Date: Thu, 23 Oct 2008 14:38:24 +0300

Package: emacs,ns
Tags: patch

$ CONFIG_SHELL=/bin/dash /bin/dash ./configure --with-ns
...
checking for X... libraries , headers 
./configure.lineno: 9373: source: not found
./configure.lineno: 9373: source: not found
./configure.lineno: 9373: source: not found
checking AppKit/AppKit.h usability... no
checking AppKit/AppKit.h presence... no
checking for AppKit/AppKit.h... no

That's because "source" is a bash feature.  But at this point one
would expect that configure should exit with an error.  However, it
continues, checks for GTK+ and finally fails for me because of missing
image librararies.  If I had them installed on this machine, it would
really configure Emacs for a GTK build.  This can't be right; if the
user says `--with-ns' he really means that.

The attached patch addresses both issues.


2008-10-23  Yavor Doganov  <yavor <at> gnu.org>  (tiny change)

	* configure.in: Use `.' instead of `source' to source
	GNUstep.conf.  Exit with an error if `--with-ns' was specified but
	<AppKit/AppKit.h> is not found.
