Core dumped when executing

[Ruiz__Mariano]

I am trying to execute the FPGA_tutorial__Compile_Flow. I have followed the instructions to install OneAPI Base Toolkit and the Intel-FPGA Add-on for Base Kit in a Linux Environment with Ubuntu 18.04. I don't  have the acceleration card installed but I have executed the aocl install (with an error in the final step because the HW is not present). I can generate the project using Eclipse but when I execute the application using the FPGA_EMULATOR it generates a "core dumped".

Debugging the application in Eclipse the error is raised in the execution of the call to deviceQueue.reset

try {
 -->   deviceQueue.reset( new queue(device_selector, async_handler{}) );
  }

Any advice of what could be the problem?

Can I run this example with the FPGA EMULATOR without the hardware installed?

When I compile the example for  CPU (make compile_flow.cpu_host) I also get a "core dumped"

Hi Mariano,

Yes, you can run with FPGA Emulator. we tried to reproduce the same issue on ubuntu 18.04 and oneAPI base kit version 2021.1-beta02, and it is working fine for both FPGA Emulator and CPU without any “core dumped”.

Can you provide details about oneAPI toolkit version that you are using, so that we can investigate more on it?

Hi Goutham:

Thanks you for your help.

Bellow are the steps followed to install the software and generate the examples.

Hope this helps to find the problem.
