CHaiDNN build error

[btwbtw01]

Hi everyone,
I try to build the hardware from makefile. I follow instructions from https://github.com/Xilinx/CHaiDNN. However I got this error.

I'm using VMware with ubuntu 16.04.3 and SDx 2018.2, and the memory is 5.7G.

By the way, I skip the first step and use zcu102 default when I face the error above. When I generate custom platform and run makefile, I face another error.

Can I skip the first step? Please help me solve these errors. Thanks a lot.
