在 xcode 中向项目添加库 - 未找到符号
我正在尝试在 xcode 中制作一个使用 pjsip 的 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，我只是不知道是什么。 :(
我在 mac os x 的这个文件夹中有 ARM 版本的库。 /Users/kudorgyozo/pjsip_iphone
在 Xcode 中： 我已指定这样的库和标头搜索路径：
对于包含：
/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/include
对于库：
/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
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
这样可以吗？因为它给了我符号未找到错误。我认为从“包含的”库中找不到任何符号。我不知道出了什么问题，我刚刚开始了解如何在基于 Linux 的系统下构建应用程序，我以前只用 C# 进行过编程。

有人为 iphone 构建 pjsip 并使用它创建了一个新项目吗？
I am trying to make an iphone app in xcode that uses pjsip. The problem is I don't know how to link the libraries. This is the first time i am using other libraries so probably i am doing something wrong i just don't know what. :(
I have the ARM version of the libraries in this folder in mac os x.
/Users/kudorgyozo/pjsip_iphone
In Xcode:
I have specified the library and header search paths like this:
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/include
for libraries:
/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
and then using the "Other linker flags" :
-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
Is this OK like this? Because it gives me symbol(s) not found errors. I think no symbol is found from the "included" libraries. I don't know what is wrong i'm just beginning to understand how building an app works under linux based systems i've only done programming in C# before.

Did anybody build pjsip for iphone and created a new project using it?

看来您缺少（至少）一些库。从符号来看，我想说：
AudioUnitRender这样的符号。pjrtp。如果有，则将其添加到“其他链接标志”中。这将修复_srtp_XXX丢失的符号。gsm。如果有，则将其添加到“其他链接标志”中。这将修复_srtp_XXX丢失的符号。speex。如果有，则将其添加到“其他链接标志”中。这将修复_srtp_XXX丢失的符号。当遇到丢失的符号时，找到它们所在位置的最佳方法是：
It seems that you are missing (at least) some libraries. From the symbols, I would say that:
AudioUnitRenderpjrtp. If there is one, then add it to the Other Link Flags. That will fix the_srtp_XXXmissing symbols.gsm. If there is one, then add it to the Other Link Flags. That will fix the_srtp_XXXmissing symbols.speex. If there is one, then add it to the Other Link Flags. That will fix the_srtp_XXXmissing symbols.When encountering missing symbols, the best way to find where they are is:
otool -Sv mystaticlib.acommand. It will displays the table of content for the static library.看来我很愚蠢，没有观察到一个名为第三方的文件夹。有缺失的库。在文档中没有提到它们，所以我什至没有费心去查看其他文件夹。我仍然缺少符号，但更少（我认为）。我还包括了 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：
以及库搜索路径：
我不必修改标头搜索路径或包含我认为的新标头。
现在缺少的内容是：
在我看来，所有内容都来自此文件 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志中。
我能够成功地构建它。缺少的框架是 AudioToolbox。谷歌搜索了 AudioSessionSetProperty，这就是我发现的。感谢您的帮助。
It seems I was stupid and didn't observe a folder called third-party. There are the missing libraries. In the docs theye were NOT mentioned so I didn't even bother looking in the other folders. I still have missing symbols but fewer (I think). I also included CoreAudio, I don't think it helped. I modified my project:
Added to the other linker flags:
And to the library search paths:
I don't have to modify the header search path's or include new headers i THINK.
Here's what is missing now:
It seems to me all are from this file libpjmedia-audiodev-arm-apple-darwin9.a but i have included it in the linker flags an in the lib search paths.
I was able to build it successfully. The missing framework was AudioToolbox. Did a google search for AudioSessionSetProperty and that is how i found out. Thanks for help.
将每个静态库添加到您的 xcode 项目中，该项目是在构建 Pjsip 库期间构建的。然后添加与音频和核心框架相关的每个框架。
Add every static library to your xcode project which has been built during build of Pjsip libraries. Then add every framework related with Audio and Core frameworks.
