Intel HLS Examples not compiling for x86-64

I have successfully installed the Intel HLS compiler with Quartus Prime 18.1 Standard Edition. However when i run the following command...

make test-x86-64

...I get the following output

i++ counter.cpp   -march=x86-64 -o test-x86-64

HLS x86-64 compile FAILED.
Makefile:40: recipe for target 'test-x86-64' failed
make: *** [test-x86-64] Error 1

The compilation works for test-gcc option. Please tell me how to resolve the issue.

I am using Ubuntu 18.04.1 LTS.

    Are you using the design example?

    Try to change the value below and see if it works?

    i++ -march=5CSEMA5F31C6 --component Target00 Target00.cpp --simulator none --clock 10ns -o Target00

      Thank you for you response. Yes, I am indeed using the design example (specifically counter.cpp) that came preinstalled with the HLS Compiler.

      I ran your command and received the same output (error) as before. I have attached the screenshot.

      Command: i++ -march=5CSEMA5F31C6 --component counter counter.cpp --simulator none --clock 10ns -o counter.cpp

      Output

        In that case, it would be unsupported OS. try to use redhat as mention below.

      That's depressing. May I ask why is it not supported for Ubuntu?

    We are sorry to inform that. Some of the OS need time for Intel engineering to get ready to support. There will be a lot of testing on the environment before it gets support.
