QOpenGLExtraFunctions缺少成员函数

Question

我正在VirtualBox中运行Ubuntu 18.04。我要构建项目后，立即收到此错误消息

error: ‘class QOpenGLExtraFunctions’ has no member named ‘glTexBuffer’; did you mean ‘glReadBuffer’?
             MBGL.glTexBuffer(GL_TEXTURE_BUFFER, GL_RGBA32F, m_buildingColorBuffer);

因此，我认为OpenGL版本不正确。我更新了所有内容， “ glxInfo”给我这些信息

OpenGL renderer string: llvmpipe (LLVM 6.0, 256 bits)
OpenGL core profile version string: 3.3 (Core Profile) Mesa 18.1.5
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.1 Mesa 18.1.5
OpenGL shading language version string: 1.40
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 18.1.5
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00

这似乎很好，因为3.x支持glTexBuffer

还有其他我可以做的事情吗，或者glTexBuffer（）的替代方法
