未找到命令 cc，导致错误 127

我正在尝试在 Ubuntu 18.04 上安装 shc

wget http://www.datsi.fi.upm.es/~frosal/sources/shc-3.8.9b.tgz
tar xvfz shc-3.8.9.tgz
cd shc-3.8.9
make

但收到以下错误：

cc -Wall  shc.c -o shc
make: cc: Command not found
makefile:31: recipe for target 'shc' failed
make: *** [shc] Error 127

生成文件：

clean:
    rm -f *.o *~ *.x.c

cleanall: clean
    rm -f shc *.x

我不知道如何修复此错误。有人可以帮忙吗？

答案1

cc 是 GNU C 编译器 (gcc) 的别名。您可以按如下方式安装它：

 sudo apt install gcc

如果由于某种原因，gcc 编译器已经安装，但是/usr/bin/cc缺少符号链接，您也可以执行以下操作：

 make CC=gcc

答案2

sudo apt install build-essential

这将安装一个 C 编译器（提供命令cc）以及从源代码构建软件可能需要的其他工具。
