Issues running Hello World openCL example missing libaltera_a10_ref_mmd.so

[JGoer1]

I'm trying to compile the hello_world openCL example. At first I was having an issue where it couldn't load the openCL platform. I got past that error by coping the $INTELFPGAOCLSDKROOT/Intel_FPGA_SSG_Emulator.icd file to /etc/OpenCL/vendors directory. Now when I go to run the host application, I get the following error:

bin/host: error while loading shared libraries: libaltera_a10_ref_mmd.so: cannot open shared object file: No such file or directory

I have updated my path to include $INTELFPGAOCLSDKROOT/bin, and set $LD_LIBRARY_PATH to $INTELFPGAOCLSDKROOT/host/linux64/lib.

Thanks for the help!

Hi,

May I know the information as below:

1. OS used
2. Quartus Version and Edition
3. FPGA used

There is an document with information that may help to you:

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/opencl-sdk/aocl_getting_started.pdf

Thanks

Hi there,

I am using Ubuntu, with Quartus 19.3 Pro, and right now I'm just trying to use the emulator and the a10_ref board.

[MEIYAN_L_Intel]

Hi,

It seems you have issues with PATH enviroment.

Can you ensure that you have set the PATH environment variable correctly. It can be something as below:

export PATH=$PATH:$INTELFPGAOCLSDKROOT/bin:$QUARTUS_DIR/bin

Please tell me as well if the problem still persists.

Thanks

[JGoer1]

Hi there,

I updated my path, and attempted to recompile for the emulator, but I'm still getting "error while loading shared libraries: libaltera_a10_ref_mmd.so: cannot open shared object file: No such file or directory" when I attempt to run the host executable.

Thanks again for your help!

Just wanted to follow up and see if there is anything else I could try? I have followed the pdf you have linked several times, but the result is always the same. It seems like I'm missing a pre-requisite piece of software, but going through the requirements section I think I have installed everything? The only other thing I can think of is that my library is in a non-standard place, and my LD_LIBRARY_PATH is wrong.

[MEIYAN_L_Intel]

Hi,

I had found some command that may help you as below:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ALTERAOCLSDKROOT/host/linux64/lib:$AOCL_BOARD_PACKAGE_ROOT/linux64/lib

Please tell me as well if the problem still persist.

Thanks

Hi there,

Thank you for the reply! We are getting closer!

The next issue I have is I'm getting the following output:

$ bin/host -emulator Querying platform for info: ========================== CL_PLATFORM_NAME = Intel(R) FPGA SDK for OpenCL(TM) CL_PLATFORM_VENDOR = Intel(R) Corporation CL_PLATFORM_VERSION = OpenCL 1.0 Intel(R) FPGA SDK for OpenCL(TM), Version 19.3   ERROR: CL_DEVICE_NOT_FOUND Location: ../common/src/AOCLUtils/opencl.cpp:356 Query for number of devices failed

I have run the following commands to set up the number of devices:

$ export CL_CONFIG_CPU_EMULATE_DEVICES=1 host $ bin/host -emulator

I found this thread (https://forums.intel.com/s/question/0D50P00003yyS6sSAE/compile-and-run-issues-of-hello-world?language=en_US) talking about needing to set the CL_CONTEXT_EMULATOR_DEVICE_ALTERA variable, however I can't find anything in the install pdf about that variable (other than it's been renamed to CL_CONTEXT_EMULATOR_DEVICE_INTELFPGA for rebranding purposes). Should I set that? if so, what should I set it to?

Thanks again for your time! I really appreciate it!

[JGoer1]

Apologies, I see that is mentioned in the hello_world example docs. I am now getting the following issue:

[MEIYAN_L_Intel]

Hi,

According to https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/opencl-sdk/aocl_getting_started.pdf for Quartus Prime Pro 19.3, there is an updated as stated: "Changed CL_CONTEXT_EMULATOR_DEVICE_INTELFPGA to CL_CONFIG_CPU_EMULATE_DEVICES."

You can refer to Chapter 2.6.4 as link mentioned above for emulating your OpenCL Kernel.

Thanks

[JGoer1]

Hi there,

I set CL_CONFIG_CPU_EMULATE_DEVICES, and I still get the following output.

Just to confirm, here is what I have CL_CONFIG_CPU_EMULATE_DEVICES set to:

$ echo $CL_CONFIG_CPU_EMULATE_DEVICES 1 bin/host

[MEIYAN_L_Intel]

Hi,

Can you try the command as below:

CL_CONFIG_CPU_EMULATE_DEVICES=1 bin/host

If the problem still persist, please tell me as well.

Thanks

Hi Mylee,

Apologies for the delayed response. I realized I was on an incompatible version of ubuntu, and have since install 16.04.

However, after following the getting started pdf, I get a coredump from the hello world example

I just attempted to sanity check something, and recompiled both the aocx and the host binary, and I'm now getting the following output.

Hello,

I'm having the exact same issue. Where you able to fix this?

Thanks,

Esteban VAlverde

[JGoer1]

The issue I had was I was on the wrong version of ubuntu. the fpga opencl sdk only support 16.04 and 14.04. The installation went smoothly after that, and now I'm getting a core dump in a hello world example.

[MEIYAN_L_Intel]

Hi,

I would like to confirm the latest problem is regarding to the ERROR: CL_INVALID_BINARY or Aborted (core dumped)?

Thanks

[JGoer1]

Hi there,

Yes, my current issue is the ERROR: CL_INVALID_BINARY error.

Thanks!

[JGoer1]

And just want to confirm the versions I'm using:

Ubuntu: 16.04

Intel FPGA OpenCL SDK: 19.3

[JGoer1]

I have also run aocl diagnose complains about not having a board installed, but that shouldn't be an issue for the emulator right?

[MEIYAN_L_Intel]

Hi,

Just to confirm with you that do you have setup the Intel Arria 10GX Development KIt as the document https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an807.pdf ?

Thanks
