I'm building multiplayer ping pong. So far the movement of the players are good. I am now focusing on the ball movement. So I add tick function which ticks the ball.
The error line is inside main.cpp: (3rd line)(The other 2 are working fine)
client_network_thread_sendto = thread(sendto_network_loop, &running, &me);
client_network_thread_recvfrom = thread(recvfrom_network_loop, &running, &opponent);
client_tick_thread = thread(tick_loop, &me, &opponent, &ball);
The linker:
make
clang++-5.0 -Wall -std=c++11 -Iinclude -g -c src/network.cpp -o build/network.o
clang++-5.0 -Wall -std=c++11 -Iinclude -g -c src/server.cpp -o build/server.o

}
I tried to clean and rebuild, searching the same question on the internet, and asking friends.
