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。下载了SourceForge的Qt应用程序的源代码，并尝试构建并运行它。通过向.pro文件添加 QT + = 语句来解决一些类似的问题之后，我坚持这个：

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:

试图在Qt Creator中构建时，我收到错误

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，清理和重建，但是会出现此错误

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

错误：依赖'.. \ .. \ .. \..\..\..\..\..\..\..\..\Qt\Qt5.1.1\5.1.1\msvc2012_64\ include \ QtPrintSupport \ qtprintsupportglobal.h'不存在。

Error: dependent '..\..\..\..\..\..\..\..\..\..\..\Qt\Qt5.1.1\5.1.1\msvc2012_64\include\QtPrintSupport\qtprintsupportglobal.h' does not exist."

当我去 C时： \ Qt \ Qt5.1.1 \5.1.1 \msvc2012_64 \include \QtPrintSupport ，qtprintsupportglobal.h就在那里！

When I go to C:\Qt\Qt5.1.1\5.1.1\msvc2012_64\include\QtPrintSupport, qtprintsupportglobal.h IS THERE!

推荐答案

您必须添加QP rinter支持你的项目.pro文件：

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

QT += printsupport
