篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了opencv4.5.5+qt5.15.2+vtk9.1+mingw81_64编译记录相关的知识,希望对你有一定的参考价值。

目录

一  VTK编译

二  无opencv_contrib编译记录

三  有opencv_contrib编译记录

四  参考链接


mingw编译器针对很多仓库代码没有编译错误,适配mingw是个好选择。

编译结果文件:

链接:https://pan.baidu.com/s/11pgNAwn_o-saygo1blJz4A 
提取码:w5so 


一  VTK编译

cd C:\\Users\\pgjgg\\Desktop\\CODE\\VTK

mkdir build

cd build

cmake -DCMAKE_BUILD_TYPE="Release"  -G "MinGW Makefiles" -DCMAKE_PREFIX_PATH="C:/Qt/5.15.2/mingw81_64/lib/cmake/Qt5"  ../

mingw32-make -j48

mingw32-make install

中间存在编译错误,继续使用编译指令:

mingw32-make -j48

或者在cmake-gui手动取消一些build。

类似这样:

 

最后管理员运行cmd.exe后,执行:

mingw32-make install

二  无opencv_contrib编译记录

git clone https://gitcode.net/opencv/opencv

cd C:\\Users\\pgjgg\\Desktop\\CODE\\opencv

mkdir build

cd build

cmake -DCMAKE_BUILD_TYPE="Release"  -G “MinGW Makefiles” -DQT_QMAKE_EXECUTABLE="C:/Qt/Tools/mingw810_64/bin/qmake.exe" -DQt5_DIR="C:/Qt/5.15.2/mingw81_64/lib/cmake/Qt5" -DCMAKE_PREFIX_PATH="C:/Program Files (x86)/VTK/lib/cmake/vtk-9.1"  ../

mingw32-make -j64

mingw32-make install

这样是没有适配QT的,需要手动在cmake-gui添加QT。

配置如下:

试了我一个通宵,遇到过一些问题。

比如编译完没有highgui模块。

这个是因为VTK没有带上QT编译。

还有sfm模块编译不了,取消build这个模块即可。
