Question

我试图在Mac OS 10.10上使用portaudio，但我在尝试编译示例程序时遇到错误。这就是我所做的：

- ./ configure＆amp;＆amp;使。没问题。

- 将示例文件＆＃34; pa_devs.c＆＃34;，libportaudio.a和portaudio.h复制到一个名为Test1的单独目录中

试图编译它

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

-got this error：

我得到的印象是我没有正确地链接事物。有什么建议吗？

Answer 1

您需要包含Apple框架：

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

正如你已经做过libportaudio.a

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"
右键点击项目＆gt;特性
构建与GT;链接器
其他选项，添加此项：

-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。

尝试使用portaudio示例，但是找不到架构x86_64＆＃34;的＆＃34; ld：符号。
