WhyCan Forum(哇酷开发者社区)

我我现在用的是根问系统是buildroot下面的那个target  我在终端窗口去查找这个analogclock  的时候 发现没有这个
然后执行上面./analogclock  -platform linuxfb 就会没有找到

qt.qpa.plugin: Could not load the Qt platform plugin "linuxfb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: linuxfb, minimal, offscreen, vnc.

里面有这个文件我特定查看了

最近编辑记录 无情一刀 (2019-04-17 14:45:30)

我刚才放了没有动过的文件系统没有问题 ，可能我以前为了删减一些东西 删掉了吧   晚上来对比下
晕哥 我现在想用荔枝派里面的那个电阻屏ns2009配置下触摸  我只要在内核中使能ns2009 
在内核中的dts中配置下的
&i2c0 {
        status = "okay";
        ns2009:ns2009@48{
                compatible = "nsiway,ns2009";
                reg = <0x48>;

        };
};

在dtsi中配置这个i2C的管脚
但是好像没有看到input这个输出

这ns2009肯定勾选了

这是 我配置了linux的dts和dtsi

是的 哈哈 大早上就是重新编译了下  可以跑起来了 然后QT里面放了一个工程也可以了
