I build the hw failed. So I tried cpu_emu. make run_cpu_em SDA_FLOW=sw_em GEMX_ddrWidth=32 GEMX_argInstrWide=1 GEMX_gemmMBlocks=8 GEMX_gemmKBlocks=8 GEMX_gemmNBlocks=8 GEMX_numKernels=4 GEMX_runGemv=0 GEMX_runTransp=0 GEMX_runGemm=1 GEMX_part=ku115 GEMX_kernelHlsFreq=250 GEMX_kernelVivadoFreq=300 GEMX_useURAM=1 GEMX_vivadoFlow=EXP XILINX_SDX=/opt/Xilinx/SDx/2017.2

And here is the error info in linking.

BTW, the platform is ku115 with 2017.2
