error when running make

[csukuangfj]

I am following the build instructions in README.md.

However, I am getting the following error

You seem to have the current working directory in your
LD_LIBRARY_PATH environment variable. This doesn't work.

The error log is not informative and I have no idea where to start debugging.

It seems it is your build environment problem. You can unset LD_LIBRARY_PATH and try again.

[csukuangfj]

I was using Ubuntu 18.04.

After switching to Ubuntu 22.04, everything works as expected.

[andyhu-stf]

The SDK support the ubuntu18.04, I think it is still your build environment problem
