Missing x_hls_utils.h file when building GEMX

[vladimir.eremin]

Hi,

I am trying to build GEMX (https://github.com/Xilinx/gemx/tree/2018.2) in SDx 2018.3 but there is a missing file: hls/utils/x_hls_utils.h

Is there a way to build this library for SDx 2018.3?

Can I download this header file somewhere?

Thanks,

Vladimir

I see this file is in /home/brucey/Xilinx/Vivado/2018.3/include/utils/x_hls_utils.h.

Probably you need to set some compilation options accordingly, or set some environment variable accordingly.

Hi brucey,

thanks for pointing to the file. I had to replace #include "hls/utils/x_hls_utils.h" with #include "utils/x_hls_utils.h".

All the env variables are set:

XILINX_VIVADO=/apps/tools/FPGA/Xilinx/Vivado/2018.3
XILINX_SDX=/apps/tools/FPGA/Xilinx/SDx/2018.3

Still having problems building the library:

/tmp/ccZ9zsA7.o: In function `boost::compute::command_queue::command_queue(boost::compute::context const&, boost::compute::device const&, unsigned long)':
/home/common/ven_veremin/SDx/gemx-2018.2/gemx/../boost/boost/compute/command_queue.hpp:145: undefined reference to `clCreateCommandQueueWithProperties'

Finally, I have managed to build and run the gemm example. 

Some paths in the Makefile had to be fixed to be used with SDAccel 2018.3.

There was also a problem with OpenCL library version, so I had to add this to gemx_fpga.h:

#undef CL_VERSION_2_0
#undef CL_VERSION_2_1
