XCode6 编译opencore-amr

注：近几天需要将amr转换为wav,从搜到了好些编译opencore-amr教程，然后看到了这个帖子《编译opencore-amr for iOS》,但是该贴子中的方法xcode6中行不通，原因是xcode6的sdk路径变化了，然后修改了其路径，i386编译成功其他就失败提示GCC编译出错，然后无果。后来又搜到了下面的这个帖子《XCode6编译opencore 》，帖子中提示“如果出现编译错误，要下载最新的command line tools”，才知道要安装command line tools（命令行工具）。安装后编译成功了。 

编译前准备：

    1、要安装command line tools。安装方法：打开终端，输入命令：xcode-select --install 。参见：http://blog.csdn.net/sqc3375177/article/details/23662755。

      2、下载opencore-amr-0.1.3.tar.gz并解压。官网： http://sourceforge.net/projects/opencore-amr/

编译步骤（转自《XCode6编译opencore》）

将下面脚本拷贝并到build.sh文件中保存到opencore-amr库根目录下，修改build.sh文件权限为可执行，运行./build.sh则可以编译出支持xcode6下模拟器及真机执行库。

其生成的头和库文件在桌面opencore-amr-lib-store目录下. 希望对要移植的朋友有帮助.

然后修改为有可运行chmod 777 build.sh

如果出现编译错误，要下载最新的command line tools
