1.2 Wine环境

# 添加i386架构
sudo dpkg --add-architecture i386
# 安装64位wine
sudo apt install wine64
# 添加wineHQ签名密钥
wget -qO- https://dl.winehq.org/wine-builds/Release.key | sudo apt-key add -
# 添加存储库
sudo apt-add-repository 'deb http://dl.winehq.org/wine-builds/ubuntu/ artful main'

2 “安装”MDK

（1）将Win下安装的MDK文件，打包压缩，传送到Ubuntn；
（2）安装Pack，将MDK文件夹Pack中的.Download下载的pack文件离线安装；
（3）Ubuntu显示隐藏文件Ctrl+H；
（4）μVision⇒ Project⇒ Manage⇒ Pack Installer⇒ File⇒ Import⇒ Keil.STM32F1xx_DFP.1.0.5.pdsc；
（5）重启μVision即可新建工程；

3 问题

3.1 不能编译

--- Error: failed to execute '\home\xdq\install\MD\Kmdk514\core\ARM\ARMCC\Bin\ArmCC'

没有指定ARMCC
依次打开:
Project-->Manage-->Compoments,Books-->Folders/Extensions

图3.1 设置路径

3.2 编译错误

【Ubuntu源文件修改】
