Thanks Kota! 

I copy the libJerasure.so to /usr/lib/x86_64-linux-gnu, and then 'startmain' works!

Thanks again!

Hi, Hao

Did you already do the setting for where shared jerasure library located?
The log message looks that Linux system doesn't have a seach path for that.

- Add /usr/local/lib path (if you installed libJerasure.so in another location, you should set the path here) into /etc/ld.so.conf
- sudo ldconfig

That helps Linux system to search shared object library.
Details is described in here. [1]
