[英]Qt4 won't compile with CMake
I'm now under Linux with KDevelop for C++ and I want to compile a Qt4 application, but when I do, it gives me the following error : 我现在使用KDevelop for C ++在Linux下,我想编译一个Qt4应用程序,但是当我这样做时,它会给我以下错误:
I compile with: 我编译:
cmake -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE=Debug /home/myname/projects/First Qt projet/
Those are the errors: 这些是错误:
-- Configuring incomplete, errors occurred!
CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97 (MESSAGE):
Could NOT find Qt4 (missing: QT_QMAKE_EXECUTABLE QT_MOC_EXECUTABLE
QT_RCC_EXECUTABLE QT_UIC_EXECUTABLE QT_INCLUDE_DIR QT_LIBRARY_DIR
QT_QTCORE_LIBRARY)
Call Stack (most recent call first):
/usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:288 (_FPHSA_FAILURE_MESSAGE)
/usr/share/cmake-2.8/Modules/FindQt4.cmake:1200 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
CMakeLists.txt:3 (find_package)
What should I do ? 我该怎么办 ?
sudo apt-get install libqt4-core libqt4-dev libqt4-gui qt4-dev-tools
This should install qt4 for you in: /usr/lib64/qt... from there cmake
should be able to pick up the location of qt for you. 这应该为你安装qt4:/ usr / lib64 / qt ...从那里cmake
应该能够为你拿起qt的位置。
You can also use that Ubuntu package manager thingy if command line isn't your style. 如果命令行不是你的风格,你也可以使用那个Ubuntu包管理器。
Not sure if this will help anyone, but for Fedora, i had the following issue: 不确定这是否会对任何人有所帮助,但对于Fedora,我有以下问题:
CMake Error at /usr/share/cmake/Modules/FindQt4.cmake:1386 (message): Found unsuitable Qt version "" from NOTFOUND, this code requires Qt 4.x Call Stack (most recent call first): bgrive/CMakeLists.txt:3 (find_package) /usr/share/cmake/Modules/FindQt4.cmake:1386中的CMake错误(消息):从NOTFOUND发现不合适的Qt版本“”,此代码需要Qt 4.x调用堆栈(最近一次调用):bgrive / CMakeLists。 txt:3(find_package)
After stepping through FindQt4.cmake i found this: 在通过FindQt4.cmake后,我发现了这个:
if (NOT QT_VERSION_MAJOR EQUAL 4)
set(VERSION_MSG "Found unsuitable Qt version \"${QTVERSION}\" from ${QT_QMAKE_EXECUTABLE}")
set(QT4_FOUND FALSE)
if(Qt4_FIND_REQUIRED)
message( FATAL_ERROR "${VERSION_MSG}, this code requires Qt 4.x")
else()
if(NOT Qt4_FIND_QUIETLY)
message( STATUS "${VERSION_MSG}")
endif()
endif()
else()
FIND_PACKAGE_HANDLE_STANDARD_ARGS(Qt4 FOUND_VAR Qt4_FOUND
REQUIRED_VARS ${_QT4_FOUND_REQUIRED_VARS}
VERSION_VAR QTVERSION
)
endif()
I know i have qt 4I solved this by simply doing: 我知道我有qt 4I通过简单地解决了这个问题:
sudo yum install qt-devel
