Sorry for the long post. Just trying to give all info.

[psychocrypt]

could you please run ldd libxmrstak_opencl_backend.so

[derjohn]

+1 Same Issue here.

$ find bin/
bin/
bin/libxmr-stak-c.a
bin/libxmrstak_cuda_backend.so
bin/xmr-stak
bin/libxmr-stak-backend.a

There is no such file ....

First I tried to compile without cuda libs, then the error is slightly different.

I use the following GPU libs:

• AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.tar.bz2
• cuda-repo-ubuntu1604-9-1-local_9.1.85-1_amd64.deb

rgds, derjohn

Same problem. Ubuntu 14.04 due to fglrx drivers... (no fglrx on 16.04 and I have old GPU) GPU: 2 x HD6970

I found a workaround: Use the V2.9.1 AMD SDK: AMD-APP-SDK-linux-v2.9-1.599.381-GA-x64.tar.bz2 instead of 3.x ..... then I compiles. (And forget to rm/mv /opt/AMDAPPSDK-3.0 as make seems to look for the /opt dir no matter what's in /etc/profile.d/AMDAPPSDK.sh )

[psychocrypt]

you linked against a other library during the build /opt/AMDAPPSDK-3.0/lib/x86_64/libOpenCL.so Set the LD_LIBRARY_PATH to the lib folder of the the amd app sdk or remove the opencl from your distribution fully.

[derjohn]

@psychocrypt It it supposed to run with AMD SDK 3.0 ?

[psychocrypt]

If you use the amd app sdk to compile the miner than you need to use this opencl version @ runtime. You need also a opencl version which knows how to create binary code for your gpu. E.g. Intel OpenCl not kbows how to create amd code therefore you need to use the vendor opencl.

[derjohn]

@psychocrypt Did you get that it doesnt work with AMD SDK 3.0, but it works with 2.9 ? The question was, if it is supposed with the 3.0 version?

[psychocrypt]

It should run with the 3.0 version. There is no reason why not.

[derjohn]

@psychocrypt As I mentioned in my comments above: The compile run fails with V 3.0 and works with V 2.9. I didnt try $now, but I think the versions are still the same.

[karpa13a]

please check the documentation of the latest release.

I have SDK 3.0 installed, but I'm receiving the same error as mentioned above, in roughly the same environment, Ubuntu 14.04.5, amd app sdk 3.0 installed, for reference, mining with an r9 270x

In some cases there are two opencl libraries installed on the system. It looks like during the compile an other library is used as that from the run. Please check if you have two linraries installed.

[baldpope]

Upon closer inspection of the error, and your follow-up comment, you're correct. On this system there was an older version of the OpenCL library and the AMD 3.0 in an alternate directory. I replaced the sym-link from the system one to point to the amd app sdk 3.0 instance.

For future reference, how can we ensure the libOpenCL is pointing to the correct 3.0 version, something in the build/compile time option? Can it be statically linked in stead of dynamic?

[psychocrypt]

There is no static opencl library available therefore it is not possible. It is hard to avoid such mistakes because each system differ and if it is an older installation the installation of the second library can be old thus the user will not remember that he/she installed it. An entry in the faq section of the documentaion can help but nobody is reading our docs ;-)

[baldpope]

I read the guide on installation/compiling. There were some additional steps I had to take with installing/building under the old platform and older hardware. Going to let the gpu sit for 24hrs to compare it against it's windows counterpart.

thank you @psychocrypt

[Orsontrius]

@baldpope What were those additional steps for building? I am getting the error originially quoted in this issue

Im on ubuntu 14.04 with HD5770s and catalyst 14.12 drivers with AMD APP SDK 3.0 and in the sdk notes I am not able to find additional steps.

[psychocrypt]

If you not disable opencl it will be build automaticaly. Check your antivir the dll is blocked from the protection software.

[Spudz76]

You don't even need any SDK at all I use headers from Khronos and point it to the OpenCL lib that comes with the drivers you want to run. For amdgpu-pro flavors it's /opt/amdgpu-pro/lib/x86_64-linux-gnu/libOpenCL.so.1 For fglrx do updatedb then locate OpenCL.so and pick the result that looks like fglrx not generic/intel/nvidia/MesaClover/etc

I will fire up my dusty HD5770 rig for testing, I have not tried it in 6mo
