我正在尝试在xcode中制作使用pjsip的iphone应用。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是什么。 ：（
我在mac os x中的这个文件夹中有ARM版本的库。 /用户/ kudorgyozo / pjsip_iphone
在Xcode中： 我已经指定了库和标题搜索路径，如下所示：
for includes：
/ Users / kudorgyozo / pjsip_iphone / pjlib / include / Users / kudorgyozo / pjsip_iphone / pjlib-util / include / Users / kudorgyozo / pjsip_iphone / pjmedia / include / Users / kudorgyozo / pjsip_iphone / pjnath / include / Users / kudorgyozo / pjsip_iphone / PJSIP /包括
对于图书馆：
/ Users / kudorgyozo / pjsip_iphone / pjlib / lib / Users / kudorgyozo / pjsip_iphone / pjlib-util / lib / Users / kudorgyozo / pjsip_iphone / pjmedia / lib / Users / kudorgyozo / pjsip_iphone / pjnath / lib / Users / kudorgyozo / pjsip_iphone / PJSIP / lib中
然后使用“其他链接器标志”：
-lpj-arm-apple-darwin9 -lpjlib-util-arm-apple-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 -lpjsip-ua-arm-apple-darwin9 -lpjsua-arm-apple- darwin9
这是好的吗？因为它给了我没有发现错误的符号。我认为“包含”库中没有找到符号。我不知道有什么问题我刚刚开始理解如何在基于Linux的系统下构建一个应用程序，我之前只用C＃编程。编辑：这是缺少的符号列表：

有没有人为iphone构建pjsip并使用它创建了一个新项目？
答案 0 :(得分：8)
您似乎缺少（至少）某些库。从符号中，我会说：
AudioUnitRender pjrtp。如果有，则将其添加到Other Link Flags。这将修复_srtp_XXX缺少的符号。 gsm。如果有，则将其添加到Other Link Flags。这将修复_srtp_XXX缺少的符号。 speex。如果有，则将其添加到Other Link Flags。这将修复_srtp_XXX缺少的符号。 遇到缺失的符号时，找到它们的最佳方法是：
otool -Sv mystaticlib.a命令。它将显示静态库的内容表。答案 1 :(得分：3)
看起来我很傻，并没有观察到一个名为第三方的文件夹。有缺少的库。在文档中没有提及他们，所以我甚至没有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，我认为它没有帮助。我修改了我的项目：
添加到其他链接器标志：
-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
到图书馆搜索路径：
/Users/kudorgyozo/pjsip_iphone/third_party/lib
我不必修改标题搜索路径或包含新标题我认为。

在我看来，所有人都来自这个文件libpjmedia-audiodev-arm-apple-darwin9.a，但我已将其包含在lib搜索路径中的链接器标记中。
我能够成功构建它。缺少的框架是AudioToolbox。谷歌搜索AudioSessionSetProperty，这就是我发现的方式。谢谢你的帮助。
答案 2 :(得分：0)
将每个静态库添加到xcode项目中，该项目是在构建Pjsip库期间构建的。然后添加与Audio和Core框架相关的每个框架。
