STM32MP157D-DK1 Qt程序交叉编译与运行测试 - 谷动谷力

上篇文章介绍了STM32MP157D-DK1开发板Qt镜像的构建，通过在Ubuntu中重新编译带有Qt功能的系统来实现。

本篇在上篇的基础上，继续搭建Qt的交叉编译环境，实现Qt程序在Ubuntu中编译，在STM32MP157板子中运行。

bitbake st-example-image-qtwayland -c populate_sdk

复制代码

中途如果报do_fetch失败的错误，可参考上篇编译镜像时的do_fetch失败的解决方法。

执行sdk中的脚本，来安装SDK到指定目录，我的是安装到Developer-Package/SDK目录

./tmp-glibc/deploy/sdk/st-example-image-qtwayland-openstlinux-weston-stm32mp1-x86_64-toolchain-4.2.1-snapshot.sh -y -d /home/xxpcb/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Developer-Package/SDK

复制代码

SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
$ . /home/xxpcb/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
xxpcb@xxpcb-ubuntu20:~/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Distribution-Package/build-openstlinuxweston-stm32mp1$

复制代码

在刚才指定安装SDK的目录中，自带了许多Qt的例子，可以使用交叉编译器来编译一个Qt程序试一下，比如：

cd
~/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Developer-Package/SDK/sysroots/cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi/usr/share/examples/gui
. ~/myTest/STM32MP157/STM32MPU-Ecosystem-v5.0.0/Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
qmake && make

复制代码

最后编译出analogclock可执行文件，可以用file指令看下文件类型。

将analogclock文件拷贝到了STM32MP157D-DK1开发板中，运行程序，可以看到一个时钟的显示效果，如下图：

本篇介绍了STM32MP157D-DK1开发板Qt程序交叉编译环境的搭建过程，并通过一个实际的Qt程序，编译后在板子中实际运行测试，验证Qt编译环境的可用性。
