重复符号Apple Mach-O链接器错误
重复符号Apple Mach-O链接器错误
提问于 2015-06-04 22:44:45
我试图在一个iOS Swift项目中使用Google。
我用Python创建了Hello项目，并将其设置在AppEngine / https://cloud.google.com/appengine/docs/python/endpoints/上
我按照下面的说明在我的项目上设置它：project，我也在使用Google+ API。
我被困在上面的第三步。为了方便起见，我在这里重新键入：
您的项目需要包括您以前运行的从foo_Sources.m生成的foo.h & ServiceGenerator文件，其中foo是您的API名称。这些文件不需要禁用ARC。
在XCode中，我将添加文件，并添加.h和.m文件。我还修改我的桥接头文件，并编辑我的构建设置头搜索路径，以包括正确的路径。
当我试图构建时，我会得到以下错误：

ld: 9 duplicate symbols for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)我的观察：
看起来，.m文件中的导入语句引起了问题。我正在为他们的SDK跟踪Google的文档，所以我想知道这是否是Swift/Objective的限制。我确实看到有人能在吉特布上设置它，不过：https://github.com/soundTricker/swift-cloud-endpoint-sample。
这里是我的问题：
- 为什么上面写着“架构armv7的9个重复符号”？我正在计算8条“重复符号”错误信息..。
- 在哪里添加"-v“以查看调用？
- 这些.o文件是什么？我需要修复的9个重复符号到底是什么？
- 我正在考虑一种解决这个问题的方法，就是用我的文件创建一个框架。这样，我只能将.h文件包含在我的项目中。这主意不好吗？
FYI:为了排除我的代码中的任何问题，我正在使用Google的代码，完全是从他们的Github存储库中克隆出来的。即使在一个干净的项目上，我也会遇到同样的问题。我正在使用Xcode v.6.3.1。

我解决了我的问题。Google生成一系列文件、实现和头文件，这些文件由Google声明添加到您的项目中。不幸的是，它还生成一个具有冲突导入语句的_Sources.m文件。我从我的iOS项目中删除了这个文件，并成功地构建了这个项目。
