在ubuntu上开发好QT应用程序,并且交叉编译好,下到板子上,不能双击运行。命令行运行提示:QWSSocket::ConnectToLocalFile could not connect:: No such file or directory。 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。添加“qws”参数,这样运行后,界面上就会有两个鼠标。查网上的资料说是在framebuffer上运行。但板子上自带的qtdemo是可以双击运行的。我应该怎么设置才行?
