added opengl3 sample, mix from @ocornut and @thelinked 2014-12-04 01:37:07 +08:00			`#`
Examples: Refactored opengl_example into a glfw specific file that can be copied and pasted. Other examples will follow. 2015-03-09 19:25:15 +08:00			`# Cross Platform Makefile`
add SDL GL3 makefile 2017-07-03 10:33:13 +08:00			`# Compatible with MSYS2/MINGW, Ubuntu 14.04.1 and Mac OS X`
added opengl3 sample, mix from @ocornut and @thelinked 2014-12-04 01:37:07 +08:00			`#`
Examples: Synced Makefile comments. Added build/ folder into git ignore list/ 2018-01-29 07:38:00 +08:00			`# You will need GLFW (http://www.glfw.org):`

Fix Clang warning with offsetof() macro? Added -Wall in OpenGL 3 example. 2014-12-07 17:58:45 +08:00			`#CXX = g++`
Examples: Makefile leave CXX alone, instead leave commented out options. (nb: codeship doesn't seem have clang++) 2018-01-29 07:55:16 +08:00			`#CXX = clang++`
added opengl3 sample, mix from @ocornut and @thelinked 2014-12-04 01:37:07 +08:00
Examples: Ignore list a little more friendly to Unix systems. 2015-08-28 23:03:05 +08:00			`EXE = opengl3_example`
Define SOURCES instead of OBJS in Makefiles. OBJS is still deduced from SOURCES, but this change gives better control over where the object files get actually written. 2016-10-22 19:26:39 +08:00			`SOURCES = main.cpp imgui_impl_glfw_gl3.cpp`
			`SOURCES += ../../imgui.cpp ../../imgui_demo.cpp ../../imgui_draw.cpp`

Examples: Fixed Makefile 2015-03-14 19:29:09 +08:00			CXXFLAGS = -I../../ -I../libs/gl3w `pkg-config --cflags glfw3`
Added printf attribute to printf like text formatting functions 2015-08-09 01:29:11 +08:00			`CXXFLAGS += -Wall -Wformat`
Examples: Speculative Makefile fix. I should get a Linux box instead on relying on Jenkins, this is pretty embarrassing. 2015-02-27 19:19:50 +08:00			`CFLAGS = $(CXXFLAGS)`

			`clean:`
Ensure `make clean` is idempotent. Prior to this, `make clean` would fail if the project was not already fully built, and a second invokation would always fail. 2016-10-22 19:02:58 +08:00			`rm -f $(EXE) $(OBJS)`
