建筑物portmidi

Question

我一直在努力在OSX 10.8.2上构建portmidi http://sourceforge.net/apps/trac/portmedia/wiki/Installing%20portmidi%20on%20Mac

无论如何，自述文件告诉我首先使用以下命令：

 make -f pm_mac/Makefile.osx

但是bash返回以下错误消息：

 [~/Desktop/portmedia/portmidi]

我没想到会轻松构建，但是这些错误对我来说似乎很陌生。 谁能解释发生了什么事？

我正在尝试为简单的C程序呈现库文件。 （.a或.la）
