Using the ubuntu image on the downloads page for the ROC-RK3399-PC

Running the command “clinfo” should show the OpenCL information about the Mali GPU, however, it shows
Number of platforms 0

How can OpenCL support be enabled?

  1. git clone https://github.com/simleb/clinfo.git
  2. apt install opencl-headers
  3. cd clinfo;make;make install
  4. cd /usr/lib/aarch64-linux-gnu/ ; ln -sf libOpenCL.so libMali.so.7.0
  5. ./clinfo

Thanks for getting back to me.

I have done the above, but now it gives a segmentation fault.

Just a print bug

  •           buffer_size += (dims[i] > 0 ? lrint(log10(dims[i])) + 1 : 1) + 2;

  •           buffer_size += (dims[i] > 0 ? lrint(log10(dims[i])) + 2 : 1) * ndims + 2;

Tried it but got make error

If I run clinfo iget
clinfo: Cannot get the number of OpenCL platforms available.
