嵌入Qt的qws參數不起作用

Question

我為嵌入式Qt創建了一個基本的Qt應用程序，但是當我使用-qws參數在目標平台上執行該應用程序時，總是會出現錯誤消息，請參見下文，

#./test_app -qws
QWSSocket::connectToLocalFile could not connect:: Connection refused QWSSocket::connectToLocalFile could not connect:: Connection refused QWSSocket::connectToLocalFile could not connect:: Connection refused QWSSocket::connectToLocalFile could not connect:: Connection refused QWSSocket::connectToLocalFile could not connect:: Connection refused QWSSocket::connectToLocalFile could not connect:: Connection refused
No Qt for Embedded Linux server appears to be running. If you want to run this program as a server, add the "-qws" command-line option. terminate called without an active exception Aborted

請指教。

謝謝。

Answer 1

• 是否再次將“ test_app”鏈接/嵌入？
• 什么打印“ strace ./test_app”
• 你玩過LD_DEBUG-environmnt變量嗎？
