移植QT 5.11.3 linuxfb文件系统（STM32MP157）

发现最近随便转载的很多啊，未经授权禁止转载！抄袭！！否则转载者死全家！！另外这是我的笔记，不是教程，难免会有错误，不具有很高的参考性，望周知。

步骤

解压qt-everywhere-src-5.11.3.tar.xz到/opt目录下：

1
sudo tar -xvf qt-everywhere-src-5.11.3.tar.xz -C /opt

进入/opt/qt-everywhere-src-5.11.3目录：

1
cd /opt/qt-everywhere-src-5.11.3

安装依赖（参考野火）：

sudo apt install python -y
sudo apt install g++ make qt3d5-dev-tools -y
sudo apt install qml-module-qtquick-xmllistmodel -y
sudo apt install qml-module-qtquick-virtualkeyboard qml-module-qtquick-privatewidgets qml-module-qtquick-dialogs qml -y
sudo apt install libqt53dquickscene2d5 libqt53dquickrender5 libqt53dquickinput5 libqt53dquickextras5 libqt53dquickanimation5 libqt53dquick5 -y
sudo apt install qtdeclarative5-dev qml-module-qtwebengine qml-module-qtwebchannel qml-module-qtmultimedia qml-module-qtaudioengine -y

修改qmake.conf配置文件：

1
vi qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf

修改如下（主要修改交叉编译器路径）：

load(qt_config)

查看特征列表：

1
./configure -list-features

这里时间比较长，耐心等一下，大概两分钟。

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/opt/qt-armhf-5.11.3'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

无报错，开始编译：

1
make -j4

漫长的过程，等啊等啊等啊等。。。。。我的电脑编译了近40分钟。

编译完成后没有成功的提示，只要日志没有错误信息就可以了。

然后安装：

1
sudo make install

安装完成后，进入/opt/qt-armhf-5.11.3目录会看到QT的文件。

在开发板上使用QT时，需要将这些文件拷贝到开发板相同的目录中才可以。

拷贝到nfs_rootfs目录：

1
sudo cp -r qt-armhf-5.11.3 ~/nfs_rootfs/opt

设置环境变量：

1
vi ~/.bashrc

添加如下内容：

1

5
export QTDIR=/opt/qt-armhf-5.11.3
export QT_QPA_PLATFORM_PLUGIN_PATH=$QTDIR/plugins
export LD_LIBRARY_PATH=$QTDIR/lib:$QTDIR/plugins/platforms
export QT_QPA_FONTDIR=$QTDIR/lib/fonts
export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0

建立字体存放文件夹：

1
sudo mkdir ~/nfs_rootfs/opt/qt-armhf-5.11.3/lib/fonts

下载文泉驿正黑字体：

1
sudo apt install fonts-wqy-zenhei

复制字体：

1
sudo cp /usr/share/fonts/truetype/wqy/wqy-zenhei.ttc ~/nfs_rootfs/opt/qt-armhf-5.11.3/lib/fonts/

运行时需要添加参数：

1
-platform linuxfb

完成！
