C 尝试portaudio示例，但得到；ld：未找到架构x86“U 64”的符号；

我试图在MacOS10.10上使用portaudio，但在尝试编译示例程序时出错。以下是我所做的：

-/配置和制作。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

-试图编译它

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

-出现以下错误：

我的印象是我没有把事情正确地联系起来。有什么建议吗？

您需要包括Apple框架：

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

---

正如你已经做的那样，libportaudio.a

谢谢凯文！为了给NetBeans用户争取时间，下面是我在安装了portaudio的Mac OS X 10.12 sierra、NetBeans 8.2（）

• 项目必须

  #包括“portaudio.h”

• 右键单击项目>属性
• 构建>链接器
• 附加选项，添加以下内容：

---

现在它开始工作了。这对于像我这样的新手来说是非常详细的。

为了便于参考，还可以包含实际的

gcc

命令。在从源代码构建了

portaudio

之后，我发现以下几点对我有用：

gcc-o设备\u测试示例/pa\u devs.c/usr/local/lib/libportaudio.a-框架核心服务-框架核心基础-框架音频单元-框架音频工具箱-框架核心音频

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