Problem compiling Gemx

[huntoona]

Hello,

I am trying to compile gemx on a C4.4xlarge instance running the FPGA developer AMI.

When I try to run the provided run_app.sh, I get this error:

make: *** [out_host/gemx_api_gemm.exe] Error 1

It would be great if anyone had guidance on how to solve this error.

Thanks, Alex

Following the documentation in GEMM_API_UG.md I get the same errors, except when I run the hardware emulation command, where I get:

Makefile:122: *** Unknown GEMX_part vu9pf1.  Stop.

It seems that the Makefile has been updated and no longer supports f1. Does that mean I can't test Gemx on AWS F1 instances?

Please checkout 2017.4 branch, which still support GEMX on F1. Before running run.sh, please setup 2017.1 SDx environment via settings64.sh/.csh.
