如何使 Qt 5.9.1 附带的 QtLinguist 工作? [英] How to make QtLinguist shipped with Qt 5.9.1 work?

问题描述

目标:使用 lupdate 生成/更新 Qt 小部件应用的 *.ts 文件.

Goal: Generate/update the *.ts files of a Qt widgets app using lupdate.

设置:

• Windows 7 Pro 64(也在 Windows 10 Home 上尝试过)
• 适用于 msvc2017 64 位的 Qt 5.9.1 Prebult 组件，
• Visual Studio 社区 2017.

问题:我已经从 QtCreator 运行了 lupdate，也从控制台手动运行，但在这两种情况下都无法正常工作.消息是:

The problem: I have run lupdate from the QtCreator, as well as manually from the console, but in neither case it is working. The message is:

启动外部工具C:\Qt\Qt5.9.1\5.9.1\msvc2017_64\bin\lupdate.exe"C:/Documents/Projects/untitled1/untitled1.pro 警告:项目错误:无法运行编译器cl".也许你忘记设置环境了?

Starting external tool "C:\Qt\Qt5.9.1\5.9.1\msvc2017_64\bin\lupdate.exe" C:/Documents/Projects/untitled1/untitled1.pro WARNING: Project ERROR: Cannot run compiler 'cl'. Maybe you forgot to setup the environment?

C:\Qt\Qt5.9.1\5.9.1\msvc2017_64\bin\lupdate.exe"完成

"C:\Qt\Qt5.9.1\5.9.1\msvc2017_64\bin\lupdate.exe" finished

否则项目编译、运行和调试都没有问题，套件:Desktop Qt 5.9.1 MSVC2017 64bit(默认)，这就是我认为环境设置正确的原因

Otherwise the project is compiled, run and debugged without problems with the kit: Desktop Qt 5.9.1 MSVC2017 64bit (default), which is the reason I think the environment is properly set up.

我找不到有关此问题的任何信息.任何想法如何使 lupdate 工作?

I can't find any information regarding this issue. Any ideas how to make lupdate work?

我正在添加当前设置(由 Qt 安装程序制作)的屏幕截图，试图阐明为什么我认为环境设置正确:

解决方案

根据 nm 在问题下的评论中提供的信息和建议，这是我找到的解决方案(相当 hack-ish，但不是太多):

Here is the solution I've found (rather hack-ish, but not too much), based on the info and advices kindly provided by n.m. in the comments under the question:

1. 使用以下单行内容创建一个 translate.bat:

"%programfiles(x86)%\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvars64.bat" &lupdate.exe %1

"%programfiles(x86)%\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvars64.bat" & lupdate.exe %1

并将其放在 %{CurrentProject:QT_INSTALL_BINS} 下(在我的例子中是 C:\Qt\Qt5.9.1\5.9.1\msvc2017_64\bin).确保 translate.bat 包含您机器上 vcvars64.bat 的正确路径.如果需要，您也可以放置另一个版本的 vcvars.

and put it under %{CurrentProject:QT_INSTALL_BINS} (in my case C:\Qt\Qt5.9.1\5.9.1\msvc2017_64\bin). Make sure that the translate.bat contains the correct path to vcvars64.bat on your machine. You may as well put another version of vcvars if you need.

1. 在 Qt Creator 中选择 Tools/Options/Environment/External Tools，然后在 Linguist 下选择 Add Toolem> 类别.将其命名为创建/更新 TS 文件.设置此条目的字段如下:

1. In Qt Creator select Tools/Options/Environment/External Tools and then Add Tool under Linguist category. Name it something like Create/Update TS files. Setup the fields for this entry as follows:

• 可执行文件:%{CurrentProject:QT_INSTALL_BINS}\translate.bat,

参数:%{CurrentProject:FilePath},

工作目录:%{CurrentProject:QT_INSTALL_BINS},

如下所示:外部工具，然后应用更改并关闭选项窗口.

as shown here: External Tools, then apply the changes and close the Options window.

1. 转到工具/外部/语言学家，选择创建/更新 TS 文件，现在它应该像往常一样完成工作了.

1. Go to Tools/External/Linguist, select Create/Update TS files and now it should do the job as usual.

背景

这里又是 link，由 nm 在评论中提供，作为此解决方案的基础.这也是 n.m. 的解释:

Here is once again the link, provided by n.m. in the comments, which served as a base for this solution. Here is also n.m.'s explaination:

从控制台运行 lupdate 绝对需要您运行vcbars*.bat 如我给您的链接中所述.那是因为lupdate 想要运行编译器，但它不知道在哪里可以找到它.vcbars*.bat 调整您的 PATH 和其他环境变量.在理论上 GUI 应该为您设置环境，但实际上可能没有.

Running lupdate from the console most definitely requires that you run vcbars*.bat as described in the link I gave you. That's because lupdate wants to run the compiler and it has no idea where to find it. vcbars*.bat tweaks your PATH and other environment variables. In theory the GUI should set up the environment for you, but in practice it probably doesn't.
