Problems discovering my Graphics Card..

Hello, First of all thanks for your work :)

I tried to compile your project on aarch64. I downloaded the ARM Compute Library( the compiled version.. )

then I linked against the libOpencl.so in 'linux-arm64-v8a-neon-cl' This is my configure line:

CFLAGS="-Os -Wall -march=armv8-a+simd+crypto+crc -mtune=cortex-a53 -std=gnu99" CPPFLAGS="-Os -Wall -march=armv8-a+simd+crypto+crc -mtune=cortex-a53 -std=gnu99" LDFLAGS="-L/opt/ARMcompute/lib/linux-arm64-v8a-neon-cl" ./configure --disable-adl --disable-adl-checks

The End Result:

------------------------------------------------------------------------
sgminer 5.5.6-ARM-RC1
------------------------------------------------------------------------

Configuration Options Summary:

  Use git version......: yes
  libcurl(GBT+getwork).: Enabled: -lcurl
  curses.TUI...........: FOUND: -lncurses
  OpenCL...............: FOUND. GPU mining support enabled
  ADL..................: Detection overrided. GPU monitoring support DISABLED

Compilation............: make (or gmake)
  CPPFLAGS.............: -Os -Wall -march=armv8-a+simd+crypto+crc -mtune=cortex-a53 -std=gnu99
  CFLAGS...............: -Os -Wall -march=armv8-a+simd+crypto+crc -mtune=cortex-a53 -std=gnu99
  LDFLAGS..............: -L/opt/ARMcompute/lib/linux-arm64-v8a-neon-cl -lpthread
  LDADD................: -ldl -lcurl submodules/jansson/src/.libs/libjansson.a -lpthread -lOpenCL    -lm -lrt

Installation...........: make install (as root if needed, with 'su' or 'sudo')
  prefix...............: /usr/local

I got some "fatal messages" when compiling, I don't know if they are important, but in the end of compilation: but 'echo $?' returns zero..

This is the relevant part of it:

/opt/sgminer-arm# make

When I check if Graphics card is detected, I got:

/opt/sgminer-arm# ./sgminer -n

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ERROR: clGetPlatformIDs from stub libOpenCL.so library called! This library can be used to resolve OpenCL symbols at compile time but must *not* be in your runtime path (You need to use a real OpenCL implementation, this one is empty)
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[00:09:42] Error -5: clGetPlatformsIDs failed (no OpenCL SDK installed?)                    
[00:09:42] clDevicesNum returned error, no GPUs usable                    
[00:09:42] 0 GPU devices max detected

I have the PAth of 'libOpenCL.so' in Dynamic Linker config '/etc/ld.so.conf', and cache remake again..

What could be triggering this problems? I have this GPU:

GPU:
    ARM Mali-T720 MP2
    Featuring 2 unified shader cores
    Complies with OpenGL ES 3.0, OpenCL 1.2

I would like to make it work, and also port a algo for it.. :)

Thanks in Advance, Regards
