Question

在升级到ubuntu 18.04后，我无法再编译我的应用程序。我正在使用mbed-cli和st核板。这是命令mbed compile

的输出

Answer 1

这是Ubuntu 18.04的特定问题。它已经被提出here

解决方法是从PPA安装arm-none-eabi-gcc。以下是说明：

删除已安装的一个：
```
sudo apt remove gcc-arm-none-eabi
```

从PPA安装一个：

sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
sudo apt-get update
sudo apt-get install gcc-arm-embedded

Answer 2

不幸的是，我无法评论OlivierM的回答，但有重要的补充。

如OlivierM之前所述，您应该删除已安装的软件并从嵌入式存储库中安装新的软件，但是如果您从主代表安装了gcc-arm-none-eabi，它还将安装binutils-arm-none-eabi，这将与gcc-arm嵌入冲突。

所以您应该删除gcc-arm-none-eabi和binutils-arm-none-eabi：

sudo apt-get remove binutils-arm-none-eabi
sudo apt-get remove gcc-arm-none-eabi

现在从PPA安装：

sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
sudo apt-get update
sudo apt-get install gcc-arm-embedded
