Can't compile for OpenCL 1.2 about katago HOT 3 OPEN

Hi, I am trying to give you some advice. For your igpu like Ryzen 5700G, the graphic core arch is still same as Vega dgpu so you can try to install driver from gpu like Radeon Vii, reference the guide Radeon™ Software for Linux® Installation.

Do you know where the lib and include dirs are for your OpenCL installation? If so, it may work to specify -DOpenCL_LIBRARY=... -DOpenCL_INCLUDE_DIR=... but replacing the ... with the appropriate paths to those directories when running cmake.

Hi David, thanks for your answer. I installed pocl via apt (sudo apt install pocl-opencl-icd), so I guess no source code was installed this way - but I'm not a dev. So I got the source for the project (git clone https://github.com/pocl/pocl.git), and tried as you said... but then I get
:~/KataGo/cpp$ cmake . -DUSE_BACKEND=OPENCL -DOpenCL_LIBRARY=~/Downloads/pocl/lib -DOpenCL_INCLUDE_DIR=~/Downloads/pocl/include -- Building 'katago' executable for GTP engine and other tools. -- -DUSE_BACKEND=OPENCL, using OpenCL backend. -- Including Git revision in the compiled executable, specify -DNO_GIT_REVISION=1 to disable -- Found OpenCL: /home/werner/Downloads/pocl/lib -- Setting up build for GNU or Clang. -- Enabling GNU-specific build options. -- Configuring done WARNING: Target "katago" requests linking to directory "/home/werner/Downloads/pocl/lib". Targets may link only to libraries. CMake is dropping the item. -- Generating done -- Build files have been written to: /home/werner/KataGo/cpp

And then when I try "make" anyway, I get a trillion errors like
/usr/bin/ld: /home/werner/KataGo/cpp/neuralnet/openclbackend.cpp:3204: undefined reference to clReleaseMemObject'
/usr/bin/ld: /home/werner/KataGo/cpp/neuralnet/openclbackend.cpp:3205: undefined reference to clReleaseMemObject' /usr/bin/ld: /home/werner/KataGo/cpp/neuralnet/openclbackend.cpp:3206: undefined reference to clReleaseMemObject'

/usr/bin/ld: /home/werner/KataGo/cpp/neuralnet/openclbackend.cpp:3152: undefined reference to clReleaseMemObject' /

which is probably due to the "lib" error in the first step. Is that fixable easily? Sorry, no dev here :)
