Mac OSX build OpenGL Super Treasure 5 (Lan Baoshu) development environment (run the first triangle program)

1. Download the resources of the OpenGL Super Treasure 5 (Lan Baoshu), the link is as follows: Http://pan.baidu.com/s/1c02PtYC, extract SB5 folder, there are books of course source code and Gltools Library.

2. Tap Xcode-->preferences-->locations-->sources Trees, then click the "+" button to add Name:gltools_include, Display Name: Gltools include folder, Path: ~/desktop/sb5/src/gltools/include (i unzipped the SB5 folder on the desktop, readers can add according to their own situation).

Create a new cocoa project under 3.Xcode, name Triangle, delete appdelegate.* two files and main.m files under project.

4. Click on the item-->targets-->build settings-->header Search Paths, add $ (gltools_include), then click on the Item-->targets-- >build Phases-->link Binary with Libraries, click "+" to add, Glut.framework,opengl.framework, click Add Other to add the desktop/sb5/src/ GLTOOLS/LIBGLTOOLS.A file

5. Right-click the project-->new file-->c++ file, add a Triangle.cpp (no header file required), copy the following code:

6.cmd + R runs, you can see:

OK, the first triangle successfully appeared (PS: I first write a blog, cough cough, a lot of imperfect, forgive me oh).
