From: George Sapountzis Date: Thu, 5 Apr 2007 15:59:42 +0000 (+0300) Subject: Move glcontextmodes.c to glx. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=885111518eeb60664b2ac708512dc8b599060280;p=mesa.git Move glcontextmodes.c to glx. It is no longer linked with DRI drivers, libGL passes function pointers through the DRI interface. --- diff --git a/src/glx/mini/Makefile b/src/glx/mini/Makefile index 217b8a76ec5..72943105c25 100644 --- a/src/glx/mini/Makefile +++ b/src/glx/mini/Makefile @@ -11,7 +11,7 @@ C_SOURCES = \ $(TOP)/src/mesa/main/dispatch.c \ $(TOP)/src/mesa/glapi/glapi.c \ $(TOP)/src/mesa/glapi/glthread.c \ - $(TOP)/src/mesa/drivers/dri/common/glcontextmodes.c \ + $(TOP)/src/glx/x11/glcontextmodes.c \ miniglx.c \ miniglx_events.c @@ -27,10 +27,7 @@ INCLUDE_DIRS = \ -I$(TOP)/src/mesa \ -I$(TOP)/src/mesa/main \ -I$(TOP)/src/mesa/glapi \ - -I$(TOP)/src/mesa/math \ - -I$(TOP)/src/mesa/transform \ - -I$(TOP)/src/mesa/swrast \ - -I$(TOP)/src/mesa/swrast_setup \ + -I$(TOP)/src/glx/x11 \ -I$(TOP)/src/mesa/drivers/dri/common \ `pkg-config --cflags libdrm` diff --git a/src/glx/x11/Makefile b/src/glx/x11/Makefile index c509d4e0851..fd83c6fc94d 100644 --- a/src/glx/x11/Makefile +++ b/src/glx/x11/Makefile @@ -46,7 +46,6 @@ INCLUDES = -I. \ -I$(TOP)/include/GL/internal \ -I$(TOP)/src/mesa/main \ -I$(TOP)/src/mesa/glapi \ - -I$(TOP)/src/mesa/drivers/dri/common \ $(LIBDRM_CFLAGS) \ $(X11_INCLUDES) @@ -63,9 +62,6 @@ INCLUDES = -I. \ default: depend $(TOP)/$(LIB_DIR)/$(GL_LIB_NAME) -glcontextmodes.c: - ln -s $(TOP)/src/mesa/drivers/dri/common/glcontextmodes.c . - # Make libGL $(TOP)/$(LIB_DIR)/$(GL_LIB_NAME): $(OBJECTS) Makefile $(TOP)/bin/mklib -o $(GL_LIB) -linker '$(CC)' \ diff --git a/src/glx/x11/glcontextmodes.c b/src/glx/x11/glcontextmodes.c new file mode 100644 index 00000000000..edb04463f61 --- /dev/null +++ b/src/glx/x11/glcontextmodes.c @@ -0,0 +1,533 @@ +/* + * (C) Copyright IBM Corporation 2003 + * 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 + * on the rights to use, copy, modify, merge, publish, distribute, sub + * license, 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 (including the next + * paragraph) 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 NON-INFRINGEMENT.
