Hi Chunbo,
after installing and first starting GW package into a separate directory, I got following error message:
Error: libnice.so.10: cannot open shared object file: No such file or directory
It seems that that library is not shipping with GW package, although its part of the MCU package. After manually copying to the lib directory at GW all seems to work fine.
Is this a knwon feature/error or I am doing something wrong?
