为Qt编译OpenCV时出错 [英] Error when compiling OpenCV for Qt
问题描述
为了在Qt中使用OpenCV，我必须通过cmake用MinGW对其进行编译.
In order to use OpenCV in Qt, I have to compile it with MinGW by cmake.
软件如下:
- Qt 5.4.0
- Opencv 2.4.11
- CMake 3.2.2
- MinGW版本未知，GCC 4.8.1
我制作文件时发生致命错误，根本不知道如何解决.
A fatal error occurred when I make file and I have no idea how to solve it at all.
[ 29%] Automatic moc for target opencv_highgui
Generating moc_window_QT.cpp
Exit code 0xc000007b
AUTOGEN: error: process for C:/opencvbuild/modules/highgui/moc_window_QT.cpp failed:
Exit code 0xc000007b
moc failed...

mingw32-make[2]: *** [modules/highgui/CMakeFiles/opencv_highgui_automoc] Error 1
CMakeFiles\Makefile2:2066: recipe for target 'modules/highgui/CMakeFiles/opencv_highgui_automoc.dir/all' failed

Makefile:145: recipe for target 'all' failed
mingw32-make: *** [all] Error 2
这些消息以cmd显示.
These messages are shown in cmd.
然后我修改了CMakeLists.txt，SET(CMAKE_AUTOMOC OFF)
Then I revised CMakeLists.txt, SET(CMAKE_AUTOMOC OFF)
modules\highgui\CMakeFiles\opencv_highgui_automoc.dir\build.make:64: recipe for target 'modules/highgui/qrc_window_QT.cpp' failed
有人知道解决方案吗?
推荐答案
2个项目可以尝试.
2 items to try.
-
尝试将
make与VERBOSE=1一起运行以增加makefile上的输出.那应该使您对哪里出了问题有了更好的了解.
Try running
makewithVERBOSE=1to increase the output on the makefile. That should give you a better idea of what is wrong.
尝试使用cmake-gui运行，然后打开高级模式以检查针对不同Qt5依赖项找到的CMake.在Mac上，我将最新的Qt安装到我的主目录中，这导致我不得不手动设置变量.这就是我的样子.
Try running with cmake-gui, then turn on advanced mode to check out what CMake found for the different Qt5 dependencies. On Mac, I install the latest Qt to my home directory, causing me to have to manually set variables. This is what it looks like for me.
希望这提供了一些有用的信息.
Hopefully this provides some useful information.
