I could't get the location infomation of which cause this error.

Who can give me some advice:  which report/log shuold read,  which part of code is dubious ？

How to reproduce the issue?

[chonhuang]

command line：XCL_EMULATION_MODE=sw_emu ./host xclbin/matrix_inverse_adjugate_method.sw_emu.xilinx_u250_xdma_201830_1.xclbin

all source code in attachment。

build command same to SDAccel Example in github

There may be some errors in the xclbin. 

Better to debug the Makefile carefully or try to build the .xo/hw_emu by step to check the Makefile and kernel API.

Can you attach the log file for the provided test case? 

For the original error you posted (looks to be based on a different design)

Loading: 'QEX.hw.xilinx_u250_xdma_201830_1.xclbin'

ERROR: dlopen of /home/sdx_worspace/QEX/bin/.run/pid/sw_emu/device0/binary_0/dltmp is failed Please check undefined symbols in the kernel

It looks to me the .xclbin generated when TARGET is set to 'hw' is loaded rather than 'sw_emu'.
