From 765b30849cd271896901f9e02c920187e82c6494 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Thu, 1 Apr 2010 13:16:06 +0800 Subject: progs/egl: Replace egltri by xegl_tri. With the switch to eglut, xegl_tri supports both X11 and EGL_MESA_screen_surface. Have it replace egltri. --- progs/egl/opengl/Makefile | 6 +- progs/egl/opengl/egltri.c | 297 +++++++++++++------------------------------- progs/egl/opengl/xegl_tri.c | 141 --------------------- 3 files changed, 88 insertions(+), 356 deletions(-) delete mode 100644 progs/egl/opengl/xegl_tri.c (limited to 'progs/egl') diff --git a/progs/egl/opengl/Makefile b/progs/egl/opengl/Makefile index 04a89b1d4a..cca843f457 100644 --- a/progs/egl/opengl/Makefile +++ b/progs/egl/opengl/Makefile @@ -15,7 +15,7 @@ EGLUT_DIR = $(TOP)/progs/egl/eglut EGLUT_DEMOS = \ eglgears \ - xegl_tri + egltri EGLUT_X11_DEMOS := $(addsuffix _x11,$(EGLUT_DEMOS)) EGLUT_SCREEN_DEMOS := $(addsuffix _screen,$(EGLUT_DEMOS)) @@ -24,7 +24,6 @@ PROGRAMS = \ demo1 \ demo2 \ demo3 \ - egltri \ eglinfo \ eglscreen \ peglgears \ @@ -48,9 +47,6 @@ demo2: demo2.o $(HEADERS) $(LIB_DEP) demo3: demo3.o $(HEADERS) $(LIB_DEP) $(CC) $(CFLAGS) $(LDFLAGS) -o $@ $< $(LIBS) $(LIBDRM_LIB) -egltri: egltri.o $(HEADERS) $(LIB_DEP) - $(CC) $(CFLAGS) $(LDFLAGS) -o $@ $< $(LIBS) $(LIBDRM_LIB) - eglinfo: eglinfo.o $(HEADERS) $(LIB_DEP) $(CC) $(CFLAGS) $(LDFLAGS) -o $@ $< $(LIBS) diff --git a/progs/egl/opengl/egltri.c b/progs/egl/opengl/egltri.c index 006e06eb03..fb1dde3529 100644 --- a/progs/egl/opengl/egltri.c +++ b/progs/egl/opengl/egltri.c @@ -1,18 +1,16 @@ /* - * Copyright (C) 1999-2001 Brian Paul All Rights Reserved. * Copyright (C) 2008 Brian Paul All Rights Reserved. - * Copyright (C) 2008 Jakob Bornecrantz All Rights Reserved. - * + * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: - * + * * 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.
