From 70b77a0fc329e2e205a596a738c7307d354e7b1c Mon Sep 17 00:00:00 2001 From: Mike Gabriel Date: Tue, 14 Apr 2015 09:24:55 +0200 Subject: library clean-up: Don't build and link libXfont.a anymore. Use system's libXfont shared library and link dynamically. --- nx-X11/lib/font/util/fontutil.c | 443 ---------------------------------------- 1 file changed, 443 deletions(-) delete mode 100644 nx-X11/lib/font/util/fontutil.c (limited to 'nx-X11/lib/font/util/fontutil.c') diff --git a/nx-X11/lib/font/util/fontutil.c b/nx-X11/lib/font/util/fontutil.c deleted file mode 100644 index 05fe5c2f2..000000000 --- a/nx-X11/lib/font/util/fontutil.c +++ /dev/null @@ -1,443 +0,0 @@ -/* $Xorg: fontutil.c,v 1.4 2001/02/09 02:04:04 xorgcvs Exp $ */ - -/* - -Copyright 1991, 1998 The Open Group - -Permission to use, copy, modify, distribute, and sell this software and its -documentation for any purpose is hereby granted without fee, provided that -the above copyright notice appear in all copies and that both that -copyright notice and this permission notice appear in supporting -documentation. - -The above copyright notice and this permission notice shall be included -in all copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS -OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF -MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. -IN NO EVENT SHALL THE OPEN GROUP BE LIABLE FOR ANY CLAIM, DAMAGES OR -OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, -ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR -OTHER DEALINGS IN THE SOFTWARE. - -Except as contained in this notice, the name of The Open Group shall -not be used in advertising or otherwise to promote the sale, use or -other dealings in this Software without prior written authorization -from The Open Group. - -*/ -/* $XFree86: xc/lib/font/util/fontutil.c,v 3.6 2001/10/28 03:32:46 tsi Exp $ */ - -/* - * Author: Keith Packard, MIT X Consortium - */ - -#ifdef HAVE_CONFIG_H -#include -#endif -#include -#include -#include -#include - -/* Define global here... doesn't hurt the servers, and avoids - unresolved references in font clients. */ - -static int defaultGlyphCachingMode = DEFAULT_GLYPH_CACHING_MODE;
