Now I have solved that compile error, before that, I did not use the source code compiled engine but from launcher installed, I follow the wiki guide A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums and compiled successfully, but has another problem, I created a project use the thirdpersoexample template, I start the server, and then start a client, from the client console command , use open 127.0.0.1 to connect the local host server, when connected, the client’s camera will move to another position , and the character can’t be controlled by the input, what’s the matter?
controlled result with mouse and keyboard just as the bellow pic:
