From 2aa53e65cd397640a44a8f3489f93ee15a536c54 Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Sat, 16 Aug 2014 19:00:01 +0000 Subject: Improve build system and autodetection. * Make ./configure standalone, that's what people expect. * Let people write a ./configure.local from scratch, not edit existing files. * Autodetect wchar, sqlite3, and manpath and act accordingly. * Autodetect the need for -L/usr/local/lib and -lutil. * Get rid of config.h.p{re,ost}, let ./configure only write what's needed. * Let ./configure write a Makefile.local snippet, that's quite flexible. --- test-wchar.c | 59 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 test-wchar.c (limited to 'test-wchar.c') diff --git a/test-wchar.c b/test-wchar.c new file mode 100644 index 00000000..0dc85ea4 --- /dev/null +++ b/test-wchar.c @@ -0,0 +1,59 @@ +/* $Id$ */ +/* + * Copyright (c) 2014 Ingo Schwarze + * + * Permission to use, copy, modify, and distribute this software for any + * purpose with or without fee is hereby granted, provided that the above + * copyright notice and this permission notice appear in all copies. + * + * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES + * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF + * MERCHANTABILITY AND FITNESS.
