From dd7276f494f81e57450fac93434ed6d9abfe8e41 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Thu, 1 Apr 2010 13:47:53 +0800 Subject: [PATCH] progs/egl: Port ES1 tri to eglut. This also removes EGL_MESA_screen_surface version of ES1 tri as eglut supports the extension. --- progs/egl/opengles1/Makefile | 35 +++- progs/egl/opengles1/screen/Makefile | 6 +- progs/egl/opengles1/screen/tri.c | 129 --------------- progs/egl/opengles1/tri.c | 311 +++--------------------------------- 4 files changed, 54 insertions(+), 427 deletions(-) delete mode 100644 progs/egl/opengles1/screen/tri.c diff --git a/progs/egl/opengles1/Makefile b/progs/egl/opengles1/Makefile index 0dd47ed..d6c09c6 100644 --- a/progs/egl/opengles1/Makefile +++ b/progs/egl/opengles1/Makefile @@ -19,6 +19,14 @@ ES1_LIBS = \ -L$(TOP)/$(LIB_DIR) -lEGL \ -L$(TOP)/$(LIB_DIR) -lGLESv1_CM $(LIBDRM_LIB) -lX11 +EGLUT_DIR = $(TOP)/progs/egl/eglut + +EGLUT_DEMOS = \ + tri + +EGLUT_X11_DEMOS := $(addsuffix _x11,$(EGLUT_DEMOS)) +EGLUT_SCREEN_DEMOS := $(addsuffix _screen,$(EGLUT_DEMOS)) + PROGRAMS = \ bindtex \ drawtex \ @@ -27,16 +35,15 @@ PROGRAMS = \ pbuffer \ render_tex \ torus \ - tri \ two_win .c.o: - $(CC) -c $(INCLUDE_DIRS) $(CFLAGS) $< -o $@ + $(CC) -c $(INCLUDE_DIRS) -I$(EGLUT_DIR) $(CFLAGS) $< -o $@ -default: $(PROGRAMS) +default: $(PROGRAMS) $(EGLUT_X11_DEMOS) $(EGLUT_SCREEN_DEMOS) @@ -72,11 +79,23 @@ two_win: two_win.o $(ES1_LIB_DEPS) $(CC) $(CFLAGS) two_win.o $(ES1_LIBS) -o $@ -tri: tri.o $(ES1_LIB_DEPS) - $(CC) $(CFLAGS) tri.o $(ES1_LIBS) -o $@ +$(EGLUT_DIR)/libeglut-x11.a $(EGLUT_DIR)/libeglut-screen.a: + @$(MAKE) -C $(EGLUT_DIR) +# define the rules for EGLUT demos +define eglut-demo-rule +$(1)_x11 $(1)_screen: $(1)_%: $(1).o $(EGLUT_DIR)/libeglut-%.a $(ES1_LIB_DEPS) +endef +$(foreach demo, $(EGLUT_DEMOS), $(eval $(call eglut-demo-rule,$(demo)))) + +# build EGLUT demos +$(EGLUT_X11_DEMOS): + $(CC) $(CFLAGS) $(LDFLAGS) -o $@ $< $(ES1_LIBS) -L$(EGLUT_DIR) -leglut-$* -lX11 +$(EGLUT_SCREEN_DEMOS): + $(CC) $(CFLAGS) $(LDFLAGS) -o $@ $< $(ES1_LIBS) -L$(EGLUT_DIR) -leglut-$* -clean: - rm -f *.o *~ - rm -f $(PROGRAMS) +clean: + -rm -f *.o *~ + -rm -f $(PROGRAMS) $(EGLUT_X11_DEMOS) $(EGLUT_SCREEN_DEMOS) + @$(MAKE) -C $(EGLUT_DIR) clean diff --git a/progs/egl/opengles1/screen/Makefile b/progs/egl/opengles1/screen/Makefile index 5b2a59c..0c3c136 100644 --- a/progs/egl/opengles1/screen/Makefile +++ b/progs/egl/opengles1/screen/Makefile @@ -13,8 +13,7 @@ ES1_LIB_DEPS = \ WINSYS_OBJS = winsys.o PROGRAMS = \ - gears \ - tri + gears .c.o: $(CC) -c $(ES1_CFLAGS) $(CFLAGS) $< -o $@ @@ -24,9 +23,6 @@ default: $(PROGRAMS) gears: gears.o $(WINSYS_OBJS) $(ES1_LIB_DEPS) $(CC) $(CFLAGS) -o $@ $@.o $(WINSYS_OBJS) $(ES1_LIBS) -tri: tri.o $(WINSYS_OBJS) $(ES1_LIB_DEPS) - $(CC) $(CFLAGS) -o $@ $@.o $(WINSYS_OBJS) $(ES1_LIBS) - clean: -rm -f *.o *~ -rm -f $(PROGRAMS) diff --git a/progs/egl/opengles1/screen/tri.c b/progs/egl/opengles1/screen/tri.c deleted file mode 100644 index bab9499..0000000 --- a/progs/egl/opengles1/screen/tri.c +++ /dev/null @@ -1,129 +0,0 @@ -/* - * Copyright (C) 2009 Chia-I Wu - * - * Based on egltri by - * 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.
