undefined symbol: glNamedBufferData when running test code

[kalyo-zjl]

Hi, when I run the tests/square_test.py. It said,
undefined symbol: glNamedBufferData when running test code

the result of $ ldd dirt/librasterise.so is as below.

There might be something wrong with my GL or EGL library, but I don't know hot to solve it, could you give me some advice?

Yes, the problem is with your GL and EGL libraries. A version from mesa is being used, which will not work with the nvidia gpu driver.

The nvidia driver package includes its own GL and EGL libraries, but where these are installed depends on your particular system. Running find /usr/lib -name '*GL*' | grep nvidia should give a list; they would all typically be in one folder, e.g. /usr/lib/nvidia-367. When building/installing dirt, set CMAKE_LIBRARY_PATH environment variable to point at that folder.

Afterwards, running ldd as before should not show mesa in the libEGL and libGL paths, but something containing nvidia.

我也遇到了这个问题
把csrc文件夹下的CMakeLists.txt里set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -ffast-math")这句话后面加上一句add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0)再重新编译就好了

I think I got a similar error. The building went fine but got the follwoing error while making

aslab@aslab-Serval-WS:~/experiments/dirt/build$ make

Any leads for fixing this error ?

Fixed it by downloading GL/gl.h and GL/glext.h files,

Thanks

I have not nvidia-*** folder in /usr/lib/
I install OpenGL by: sudo apt install freeglut3-dev
and how can I install OpenGL correctly?

[pmh47]

@wkailiu You need the version of OpenGL that comes with the nvidia driver -- not the one shown from freeglut/mesa. I don't know where the nvidia one is installed on your system; it should have shown up in that find command. Have you tried reinstalling the nvidia driver?
