将库添加到xcode中的项目 - 未找到符号

我正在尝试在xcode中使用pjsip制作iphone应用程序。问题是我不知道如何链接库。这是我第一次使用其他库，所以可能我做错了什么，我只是不知道。 :(将库添加到xcode中的项目 - 未找到符号

我的库的ARM版此文件夹中的Mac OS X中 /用户/ kudorgyozo/pjsip_iphone

在Xcode中：我已指定这样的库和头搜索路径：

为包括：

/用户/ kudorgyozo/pjsip_iphone/pjlib /包括/用户/ kudorgyozo/pjsip_iphone/pjlib-util的/包括/用户/ kudorgyozo/pjsip_iphone/pjmedia /包括/用户/ kudorgyozo/pjsip_iphone/pjnath/include/Users/kudorgyozo/pjsip_iphone/pjsip/include

图书馆：

/用户/ kudorgyozo/pjsip_iphone/pjlib/LIB /用户/ kudorgyozo/pjsip_iphone/pjlib-util的/ lib中/用户/ kudorgyozo/pjsip_iphone/pjmedia/LIB /用户/ kudorgyozo/pjsip_iphone/pjnath/lib目录/用户/ kudorgyozo/pjsip_iphone/PJSIP/lib目录

，然后使用 “其他连接标志”：

-lpj臂，苹果darwin9 -lpjlib-UTIL-ARM-苹果darwin9 - lpjmedia-arm-apple-darwin9 -lpjmedia-audiodev-arm-apple-darwin9 -lpjmedia-codec-arm-apple-darwin9 -lpjsdp-arm-apple-darwin9 -lpjnath-arm-apple-darwin9 -lpjsip-arm-apple- darwin9 -lpjsip-simple-arm-apple-darwin9 -l pjsip-ua-arm-apple-darwin9 -lpjsua-arm-apple-darwin9

这样的行业吗？因为它给了我符号（s）找不到错误。我认为从“包含”库中找不到符号。我不知道什么是错，我刚开始了解如何构建一个应用程序在基于Linux的系统下工作，我之前只使用C＃编程。

有没有人建造PJSIP为iPhone创建和使用一个新的项目？

什么符号丢失？这些符号来自哪个库？你链接提供这些符号的库吗？ – 2010-06-01 12:34:38

我正在链接来自pjsip项目的库。所有缺失的符号都来自这些库。 – 2010-06-01 13:07:25

看起来你缺少（至少）一些库。从符号，我会说：

您可能忘了添加CoreAudio框架。需要解析符号，如AudioUnitRender
应该有一个来自pjsip的RTP库，其中包含pjrtp。如果有，则将其添加到其他链接标志。这将修复_srtp_XXX缺失的符号。
应该有一个来自pjsip的GSM库，其中包含gsm。如果有，则将其添加到其他链接标志。这将修复_srtp_XXX缺失的符号。
应该有一个来自pjsip的Speex库，其中包含speex。如果有，则将其添加到其他链接标志。这将修复_srtp_XXX缺失的符号。

当遇到没有的符号，以寻求最佳的方式，他们都是：

看的符号名。好的图书馆总是在他们的符号前面加上，所以从名字上你可以猜出哪个图书馆拥有它。
如果你有一个静态库，并且你想知道导出的符号，那么你可以使用otool -Sv mystaticlib.a命令。它将显示静态库的内容表。

2010-06-02 06:21:01

嗯..谢谢，我不知道如何/在哪里得到那些你提到的其他图书馆。我曾尝试添加coreaudio，但我看到有53个错误，所以我删除它。我从来没有确认哪些符号添加后虽然失踪。 – 2010-06-02 06:38:53

添加CoreAudio不能解决缺失的AudioUnitRender ...奇怪的 – 2010-06-02 06:48:46

如何添加CoreAudio？它是一个框架，因此将其作为框架添加到项目中应该设置正确的标志。如果您有一个包含所有pjsip库的文件夹，只需运行otool命令（请参阅我的答案）以查看是否可以找到符号。如果符号不存在，那么你应该检查pjsip端如何获取RTP，GSM和Speex库。 – 2010-06-02 07:38:06

看来我很愚蠢，没有观察到名为第三方的文件夹。有缺失的库。在文档中他们没有被提及，所以我甚至不打扰在其他文件夹中查找。我仍然缺少符号但更少（我认为）。我还包括CoreAudio，我不认为它有帮助。我修改我的项目：

添加到其他连接器选项：

 
-lg7221codec-arm-apple-darwin9 -lgsmcodec-arm-apple-darwin9 -lilbccodec-arm-apple-darwin9 -lmilenage-arm-apple-darwin9 -lresample-arm-apple-darwin9 -lspeex-arm-apple-darwin9 -lsrtp-arm-apple-darwin9

而到了库搜索路径：

 
/Users/kudorgyozo/pjsip_iphone/third_party/lib

我没有修改头搜索路径的或者包括我认为新的标题。

这里现在缺什么：
