当我试图用Project ERROR: Unknown module(s) in QT: positioning构建依赖于QT5的项目时,出现了错误的qmake,我怀疑以前安装的旧QT4安装中可能会出现问题。
qmake -version
QMake version 3.0
Using Qt version 5.2.1 in /usr/lib/x86_64-linux-gnu
所以我的问题是:
1.如何解决这一错误?
2.如何完全删除Qt4 (并可能重新安装QT5?)?
更新:
which qmake
/usr/bin/qmake
ls -l /usr/bin/qmake
lrwxrwxrw
我想在capybara-webkit上使用qt5的QtWebKit。
brew uninstall qt
Uninstalling /usr/local/Cellar/qt/4.8.4...
brew install qt5
This formula is keg-only: so it was not symlinked into /usr/local.
/usr/local/Cellar/qt5/5.0.2: 3103 files, 140M, built in 60.9 minutes
如果强制brew为qt5创建符号链接,则可以为capybara-webkit构建本机扩展。

我想要创建一个项目使用VSCode+CMake+VCPKG(VTK+Qt5),我仍然想与队友分享我的VCPKG依赖。所以我出口VCPKG。
当我尝试find_package(Qt5 COMPONENTS Core REQUIRED)时,问题发生了

我刚刚在Arch中安装了Qt5,但是只有qtconfig不能工作:
%> qtconfig
qtconfig: could not exec '/usr/lib/qt/bin/qtconfig': No such file or directory
是的,没有这样的文件,甚至连/usr/lib/qt5/bin/qtconfig都没有
有什么办法找到它吗?我需要调整smplayer的字体,它现在链接到Qt5库。
我是一名学生,正在写一个项目。我已经创建了一个程序(这里是SVN:https://mysvn.ru/Ilya_Antonov/antonov_sem_prj的链接)。我使用CMake构建它并生成.sln项目。但在Visual Studio中运行时,会出现一些错误:编译器无法打开文件"drumswindow.h“和"mainwindow.h”(致命错误C1083)。请看一下我的CMakeLists.txt: cmake_minimum_required(VERSION 3.1.0)
