苹果Mach-O的链接器错误（20） - 适用于建筑的ARMv7未定义的符号 [英] Apple Mach-O Linker Errors (20) - Undefined symbols for architecture armv7

问题描述

后，我在其它链接器标记添加-all_load打造设定一次，我补充说：libPusher-combined.a和它的头文件，我收到这些错误。我跟着<一个href=\"https://github.com/lukeredpath/libPusher/wiki/Adding-libPusher-to-your-project\">instructions正是达打字的-all_load（在添加到您的iOS项目，但我最终得到20 Mach-O的连接错误的部分使用pre-编译静态库中：/任何人都可以请帮我这个？

I received these errors after I added " -all_load " in the "Other Linker Flags" build setting once I added "libPusher-combined.a" and its header files. I followed the instructions exactly up to the part of typing in "-all_load" (under "Using a pre-compiled static library" in the "Adding to your iOS Project", but I ended up getting 20 Mach-O Linker errors. :/ Could anyone please help me with this?

下面是错误的：

如果您需要了解更多信息，只问。我希望我不会给太多的麻烦。先谢谢了。

If you need more information, just ask. I hope that I'm not giving too much trouble. Thanks in advance.

推荐答案

你可以看看你的靶子>构建阶段。是否有存在与否这些文件？如果你正在运行的模拟器那么首先您需要构建该库无论我猜你正在使用SRWebSocket库的模拟器。只需打开该项目，只是做一个建立模拟器和文件从build文件夹复制，然后添加到您的项目，并执行相同的设备，如果你在设备上运行你的应用程序。

Can you check out in your target->Build Phase. whether these files exist there or not ? and if you are running for simulator then first you need to make a build for simulator of that library whatever i guess you are using SRWebSocket library. Just open that project and just make a build for simulator and copy the files from build folder and then add to your project and do the same for the device if you are running your app on device.
