我正在尝试从源代码编译 OpenCV 3.4.0，但我遇到了 QT 和 OpenGL 之间冲突的声明问题。从 QT4 升级到 QT5 解决了一些问题，但不是全部。看起来 GLsizeiptr 和 GLintptr 在 OpenGL 头文件和 QT 头文件中都声明了。

我试图更换

#include <GL/glx.h>

和

#include <GLES3/gl3.h>

在 window_QT.cpp 中，但这只会产生更多的声明问题。

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

问题已解决：我刚刚尝试使用直接从 github 克隆的最新版本的 opencv 进行全新安装，并且安装过程完美无缺。
