cross compile error
when i run ninja to cross compile the project,it show : /spa/plugins/avb/avb-pcm.c: In function ‘setup_socket’: ../spa/plugins/avb/avb-pcm.c:560:22: error: storage size of ‘txtime_cfg’ isn’t known struct sock_txtime txtime_cfg; ^~~~~~~~~~ ../spa/plugins/avb/avb-pcm.c:572:36: error: ‘SO_TXTIME’ undeclared (first use in this function); did you mean ‘SI_TIMER’? res = setsockopt(fd, SOL_SOCKET, SO_TXTIME, &txtime_cfg, ^~~~~~~~~ SI_TIMER ../spa/plugins/avb/avb-pcm.c:572:36: note: each undeclared identifier is reported only once for each function it appears in
so how to fix the problem?
