而我'；我正在尝试gcc制作linux头文件--`uname-r`I'；我出错了

我正在尝试安装droidcam Linux客户端。当我运行命令时

gcc make linux-headers-`uname -r`

我得到以下错误：

gcc: error: make: No such file or directory
gcc: error: linux-headers-5.4.0-42-generic: No such file or directory
gcc: fatal error: no input files
compilation terminated.

我试过了

sudo apt-get install linux-headers-`uname -r`

这告诉我它已经存在了

我刚刚运行了这个命令
