致命错误：GLES2/gl2.h：没有此文件或目录

我正在尝试在 RPi 3 上安装 Urho3D。（GPU = 768 MB）

我安装了所有必需的依赖项。所有步骤都顺利进行。直到在最后的 make 步骤中出现此错误：

[ 56%] Building CXX object Source/Urho3D/CMakeFiles/Urho3D.dir/Graphics/Skybox.cpp.o

有什么建议吗？我该怎么办！？

答案1

我在编译其他项目时也遇到了类似的错误。按照@steeldriver 的建议，我通过安装库解决了这个问题：

sudo apt-get install libgles2-mesa-dev
