我在这个特定文件的Stack Overflow上没有看到任何内容。我从http://www.ftdichip.com/Drivers/D2XX.htm为OS X 10.7下载并安装了FTDI serial-usb适配器的驱动程序。现在，我试图从名为＆＃34; Simple＆＃34;的文件夹中获取示例代码。在包含的样本内。我创建了一个新的XCODE（4.5）项目并导入了必要的项目。
我收到以下编译错误：

makefile不是xCode项目的一部分。它是原始示例代码的一部分。我不知道如何解决这个问题。我很感激任何帮助！
main.c中：
/*
Simple example to open a maximum of 4 devices - write some data then read it back.
Shows one method of using list devices also.
Assumes the devices have a loopback connector on them and they also have a serial number
To build use the following gcc statement
(assuming you have the d2xx library in the /usr/local/lib directory).
