尝试portaudio示例，但获取“ld：symbol（s）not found for architecture x86_64”

Question

我正在尝试在Mac OS 10.10上使用portaudio，但在尝试编译示例程序时遇到错误。 这就是我所做的：

-./configure&& make。 没问题。

- 将示例文件“pa_devs.c”，libportaudio.a和portaudio.h复制到名为Test1的单独目录中

- 编译它

gcc -o Test1 pa_devs.c libportaudio.a -lm

- 这个错误：

我得到的印象是我没有正确地连接东西。 有什么建议？

Answer 1

您需要包含Apple框架：

• CoreServices.framework
• CoreFoundation.framework
• AudioUnit.framework
• AudioToolbox.framework
• CoreAudio.framework

而你已经做了libportaudio.a

Answer 2

谢谢凯文！ 为了获得NetBeans用户的时间，我在Mac OS X 10.12 sierra，Netbeans 8.2上安装了portaudio（ http://macappstore.org/portaudio/ ）

• 项目必须#include "portaudio.h"
• 右键单击项目>属性
• 构建>链接
• 附加选项，添加：

-v /usr/local/lib/libportaudio.a -framework CoreServices -framework 
CoreFoundation -framework AudioUnit -framework AudioToolbox -framework CoreAudio

现在它有效。 这对于像我这样的新手来说很详细。
