1126运行Qt demo程序报错
本帖最后由 2765961790 于 2022-3-2 18:31 编辑使用设备：firefly RV1126开发板，firefly10寸屏
固件版本：.repo/manifests/rv1126_rv1109_linux_release.xml -> rv1126_rv1109_linux/rv1126_rv1109_linux_20220125.xml
QT配置及交叉编译方法按照firefly的Buildroot教程 https://wiki.t-firefly.com/zh_CN/Firefly-Linux-Guide/development_buildroot.html
使用的是32位的arm包，解压此包到开发板/usr/lib目录
编译mainwindow程序为arm架构的程序
mainwindow: ELF 32-bit LSB executable, ARM, EABI5 version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 4.4.0, not stripped
在开发板上运行此demo时报错
./mainwindow: error while loading shared libraries: libmali.so.1: cannot open shared object file: No such file or directory于是官方的firefly-qt-5.12.2-arm/host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib下的文件拷贝到开发板的/usr/lib目录下，运行程序，不再有之前的报错，但是有新的报错，部分报错信息如下：
# ./mainwindow
./mainwindow: /lib/libstdc++.so.6: no version information available (required by ./mainwindow)
./mainwindow: /lib/libstdc++.so.6: no version information available (required by ./mainwindow)

./mainwindow: /lib/libm.so.6: version `GLIBC_2.29' not found (required by /usr/lib/libQt5Gui.so.5)
用 ./mainwindow和./mainwindow -platform eglfs或者./mainwindow -platform wayland都是这种错误
希望官方能给个解决方法，或者指导下RV1126怎么运行Qt程序
1126 没有 GPU 默认没有装 wayland 所以 eglfs 和 wayland 都不能用，试一下指定 linuxfb
export QT_QPA_FB_DRM=1
export QT_QPA_PLATFORM=linuxfb:rotation=0 板蓝根 发表于 2022-3-3 17:37

还是一样的报错信息啊{:4_96:} 板蓝根 发表于 2022-3-3 17:37

环境变量加在/etc/profile里也是这样 2765961790 发表于 2022-3-4 09:58

默认的SDK编译已经将QT编译进buildroot系统了。尝试使用buildroot系统的qmake工具进行编译。
cd 你的QT工程
path-to-sdk/buildroot/output/firefly_rv1126_rv1109/host/bin/qmake ./你的QT工程
make将编译好的程序通过adb推送到板子上。
根据上面export设置QT环境变量。然后执行。

是库的引导问题，我替换了报错的库就没有那些报错了，现在是这些问题
# export QT_QPA_FB_DRM=1
# export QT_QPA_PLATFORM=linuxfb:rotation=0
# ./mainwindow
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: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland.
这个是哪方面的问题？ 用的firefly最新的SDK固件，屏幕也是firefly的10寸mipi屏，但是系统里却没fb设备，屏幕也不亮
