Qt 无法打开包含文件:'QPrinter' [英] Qt Cannot open include file: 'QPrinter'

问题描述

我是 Qt 的新手.下载 SourceForge 的 Qt 应用程序的源代码，并尝试构建和运行它.通过将 QT += 语句添加到 .pro 文件解决了一些类似问题后，我被困在这个问题上:

I am new to Qt. Downloaded source code for a Qt application of SourceForge, and tried to build and run it. After working through a few similar problems by adding QT += statements to .pro files, I am stuck on this one:

在尝试构建 Qt Creator 时，我收到错误提示

On attempting to build in Qt Creator, I get errors saying

错误:C1083:无法打开包含文件:'QPrinter':没有这样的文件或目录

error: C1083: Cannot open include file: 'QPrinter': No such file or directory

我尝试将 QT += printsupport 添加到 .pro 文件中，进行清理和重建，但出现此错误

I tried adding QT += printsupport to the .pro file, cleaning, and rebuilding, but that gives this error

错误:依赖 '......................QtQt5.1.15.1.1msvc2012_64includeQtPrintSupportqtprintsupportglobal.h' 不存在."

Error: dependent '......................QtQt5.1.15.1.1msvc2012_64includeQtPrintSupportqtprintsupportglobal.h' does not exist."

当我转到 C:QtQt5.1.15.1.1msvc2012_64includeQtPrintSupport 时，qtprintsupportglobal.h 就在那里！

When I go to C:QtQt5.1.15.1.1msvc2012_64includeQtPrintSupport, qtprintsupportglobal.h IS THERE!

推荐答案

您必须在项目的 .pro 文件中添加 QPrinter Support:

You have to add QPrinter Support to your project's .pro file:

QT += printsupport
