IOS教程之ios编译libfreetype，并顺应armv7,armv7s,arm64仓酷云

照着书上的例子，一个一个做下来，只要不是文盲，就都会的呀，没有体现我的一点点个人价值。所以我决定了，不能再这样下去在github里看到大家网公布的一个CCHtmlLabel的RichText控件，能够显现庞大的html布局的富文本，设置好以后发明在摹拟器下面能顺遂跑起来，但在真机上却编译失利。
看errorlog的意义是指没有armv7s的slice，再看了一下CCHtmlLabel所用的libfreetype库，是2011年编译的，有点旧，事先iphone4s才刚出呢，固然没有armv7s了。
因而到SourceForge下载了freetype的源代码，编译成lib后再交换本来的libfreetype.a，再次用Xcode编译全部游戏项目，发明仍是有个linker的毛病：undefinedreferenceto`BZ2_bzDecompressInit。
这个复杂，在xcode里增加对libbz2.1.0.dylib的援用便可。
有必要的请到这里下载：http://download.csdn.net/detail/visualcatsharp/7076545
上面再纪录一下编译的历程
