Question

我正在尝试从源代码编译OpenCV 3.4.0，但我遇到了QT和OpenGL之间存在冲突的声明问题。从QT4升级到QT5解决了一些问题，但并非全部。看起来GLsizeiptr和GLintptr都在OpenGL标头和QT标头中声明。

我试图替换

#include <GL/glx.h>

带

#include <GLES3/gl3.h>

在window_QT.cpp中

但是只创建了更多的声明问题。

关于如何解决这个问题的任何想法？

（我的机器是运行Ubuntu 16.04.3 LTS的armv7l（Odroid XU4））

我正在运行的cmake命令：

cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local -DWITH_QT=5 -DWITH_OPENGLES=ON -DWITH_V4L=ON -DWITH_TBB=ON -DBUILD_TBB=ON -DENABLE_VFPV3=ON -DENABLE_NEON=ON ..

make -j8

我得到的错误：

[ 62%] Built target opencv_videoio
[ 63%] Built target opencv_superres
[ 63%] Building CXX object

感谢您的帮助！

问题解决了：我刚尝试使用最新版本的opencv直接从github克隆进行全新安装，安装完美无缺。
