Building Qt Xcode Projects From the Command Line
提问by Ankur Sethi
I've been playing around with Qt for a few hours now. I found that qmake produces Xcode project files on Mac OS X instead of good ol' makefiles. I don't want to launch Xcode every time I want to build "Hello, world".
我已经玩 Qt 几个小时了。我发现 qmake 在 Mac OS X 上生成 Xcode 项目文件，而不是好的 ol'makefile。我不想每次想构建“Hello, world”时都启动 Xcode。
How do I make qmake generate regular makefiles or, if that's something that cannot be done on the Mac, how do I compile .xcodeprojfiles from the command line?
我如何让 qmake 生成常规的 makefile，或者，如果这在 Mac 上无法完成，我如何.xcodeproj从命令行编译文件？
I tried xcodebuild -project myProject -alltargets. I get a lot of output followed by Abort trap.
我试过了xcodebuild -project myProject -alltargets。我得到很多输出，然后是Abort trap.

The open-source Qt binary installers for OS X from Trolltech default to creating .xcodeproj files when you run qmake. I don't use XCode for editing so it is a pain to open it to compile the project.
当您运行 qmake 时，Trolltech 的 OS X 开源 Qt 二进制安装程序默认创建 .xcodeproj 文件。我不使用 XCode 进行编辑，所以打开它来编译项目很痛苦。
To compile your projects from Terminal.app, just set an environment variable of QMAKESPEC to macx-g++
要从 Terminal.app 编译您的项目，只需将 QMAKSPEC 的环境变量设置为 macx-g++
If you want to just compile a certain project from the terminal, go into that directory and run
如果您只想从终端编译某个项目，请进入该目录并运行
qmake -spec macx-g++
When you run qmake, this will create a Makefile which you can use by running make.
当您运行 qmake 时，这将创建一个 Makefile，您可以通过运行 make 来使用它。

$ man xcodebuild
So a typical command might be something like:
所以一个典型的命令可能是这样的：
$ xcodebuild -project myProject.xcodeproj -alltargets

Try the following way. It has to work.
试试下面的方法。它必须工作。
xcodebuild -project myProject.xcodeproj -alltargets
I have used this method in most of my projects.
我在我的大部分项目中都使用过这种方法。

Looking at this part of your back trace:
查看您的回溯的这一部分：
# 2008-12-18 20:40:52.333 xcodebuild[1070:613] [MT] ASSERTION FAILURE in /SourceCache/DevToolsBase/DevToolsBase-921/pbxcore/FileTypes/PBXCFBundleWrapperFileType.m:174 # Details: path should be a non-empty string, but it's an empty string # Object: # Method: -subpathForWrapperPart:ofPath:withExtraFileProperties: # Thread: {name = (null), num = 1}
# 2008-12-18 20:40:52.333 xcodebuild[1070:613] [MT] /SourceCache/DevToolsBase/DevToolsBase-921/pbxcore/FileTypes/PBXCFBundleWrapperFileType.m 中的断言失败：路径应该是非-174 #空字符串，但它是一个空字符串 # Object: # Method: -subpathForWrapperPart:ofPath:withExtraFileProperties: # Thread: {name = (null), num = 1}
This implies that something, maybe one of your configuration variables, is blank when it needs to refer to a file. What I'm wondering is if maybe you have an extra target in your project that doesn't work, so that building with -alltargets is what's causing your problem.
这意味着某些东西（可能是您的配置变量之一）在需要引用文件时是空白的。我想知道的是，您的项目中是否有一个额外的目标不起作用，因此使用 -alltargets 进行构建是导致您出现问题的原因。
I tested xcodebuild without any arguments on one of my projects just now - it did a default build of my project without errors. What happens if you try it without arguments?
我刚刚在我的一个项目上测试了没有任何参数的 xcodebuild - 它没有错误地对我的项目进行了默认构建。如果你在没有参数的情况下尝试会发生什么？
