(1)TRDqt程序交叉编译,结果:
(2)helloworld qt程序+nfs文件系统,结果:
libdbus-1
(3)helloworld qt程序+sd文件系统,结果:
Could not open display
sh: line 1: 2362 Aborted DISPLAY=':0.0' /home/root/helloworld
Application finished with exit code 134.之后sunny@sunny-VirtualBox:/nfsroot/lib$ ssh -X root@192.168.22.108
root@192.168.22.108's password:
xauth: file /home/root/.Xauthority does not exist
root@plnx_aarch64:~# ./helloworld

xcb是图形库,eglfs很麻烦
