关于Buildroot
buildroot使用介绍
The Buildroot user manual
通过buildroot+qemu搭建ARM-Linux虚拟开发环境
目标
简单描述:
1.buildroot的下载编译过程
2.支持QT的配置说明及步骤
模拟环境
在开始编译之前, 查询了一些资料, 对模拟器的支持如下:
ubuntu下使用qemu-system-arm模拟arm环境
Buildroot and QEMU – the quickest receipe for your own Linux
$ sudo apt-get install qemu-system-arm $ qemu-system-arm --version QEMU emulator version 4.2.1 (Debian 1:4.2-3ubuntu6.14) Copyright (c) 2003-2019 Fabrice Bellard and the QEMU Project developers
而在成功编译完成后, 生成了output/images/start-qemu.sh, 并且可以直接运行
上面的步骤是否可以省略?

如何支持 Qt
前面编译出来的系统, 并没有对QT的支持, 仅仅用于验证开发环境的一些尝试
make menuconfig
默认的模拟配置并不支持勾选QT选项
*** Qt5 needs host g++ >= 5.0, and a toolchain w/ gcc >= 5.0, wchar, NPTL, C++, dynam ***
估计是问题有些太低级, 所以, 不管GOOGLE还是BAIDU,
没有文章可以给出很好的答案来说明, 如何让QT选项可以勾选.
解决:
修改Toolchain后, 终于可以用QT的选项了:
重新编译
# 清除, 不清除编译会有报错 $ make clean # 重新编译 $ make
编译完成后, 可以找到qmake

如何在Buildroot中编译Qt请参考:

尝试执行qmake生成Makefile文件时报错:
失败的尝试 1

解决: 打开QT中gui->widgets配置
重新编译
# 清除, 不清除编译会有报错 $ make clean # 重新编译 $ make
编译完成后, analogclock已经编译好了

尝试删除 analogclock Makefile .moc .obj .pch, 再执行qmake, 可以正常生成Makefile
执行make, 生成analogclock
