Default mfakto error while running

Hello,

I am attempting to use mfakto with my GPU (MSI R5770 Hawk Radeon HD 5770). I downloaded the files and installed OpenCL via

Code:
sudo apt install ocl-icd-opencl-dev
and then ran mfakto via

Code:
./mfakto-x64
I get the following output

Code:
Runtime options
  Inifile                   mfakto.ini
  Verbosity                 1
  SieveOnGPU                yes
  MoreClasses               yes
  GPUSievePrimes            82486
  GPUSieveProcessSize       24Ki bits
  GPUSieveSize              96Mi bits
  FlushInterval             8

  StopAfterFactor           class
  PrintMode                 compact

  ComputerID                none
  TimeStampInResults        yes
  VectorSize                4
  GPUType                   AUTO
  SmallExp                  no
  UseBinfile                mfakto_Kernels.elf
Compiletime options
Select device - Error -1001 (Unknown errorcode (not an OpenCL error)): clGetPlatformIDs(num)
ERROR: init_CL(3, 0) failed
How can I resolve this?

Try confirming the opencl is active, such as with an appropriate utility from the middle list of http://www.mersenneforum.org/showpos...4&postcount=31. No device found is sometimes a result of no installation or install failed or isn't loaded yet. (No experience with ubuntu myself so can't help you with specifics.)

Check your hardware is supported, such as at one of the links given at
https://stackoverflow.com/questions/...pliant-cpu-gpu

Good luck ;)
