Linux内核运行稀疏失败-/bin/sh:1:稀疏:找不到 [英] Linux Kernel run sparse failed - /bin/sh: 1: sparse: not found

问题描述

我在linux内核上运行稀疏.

I run sparse on linux kernel.

但是它会引发以下错误:

But it throws the following error:

有人可以提供一些线索吗?

Could anyone give some clue?

非常感谢您！

推荐答案

更简单的方法:

首先，从官方渠道在主机上下载并安装 sparse .

Easier method :

First, download and Install sparse on your host-PC from the official channel.

例如，在Ubuntu上运行，
$ sudo apt-get install sparse

For example, on Ubuntu run,
$ sudo apt-get install sparse

或者，如果您尝试从源代码构建sparse，那么我们需要确保在运行make install命令后，sparse二进制文件位于/usr/bin/sparse.

Alternately if you are attempting to build sparse from its sources, then we need to ensure that after running the make install command the sparse binary is present at /usr/bin/sparse.

这可以通过打开新终端并在其中运行which sparse命令来确认.它应该输出类似于以下内容:

This can be confirmed by opening a new terminal and running the which sparse command in it. It should output similar to the following :

$ which sparse
/usr/bin/sparse

在同一终端中，导航到Linux内核源目录，然后尝试make C=2在Linux内核源上运行sparse.

In the same terminal, navigate to the Linux kernel source directory and attempt make C=2 to run sparse on the Linux kernel source.

注意:从您的日志看来，sparse已安装到/home/lovegcy/bin/中.确保已添加路径/home/lovegcy/bin/您的$PATH环境变量.否则，系统将无法找到sparse二进制文件.

Note : From your logs it appears that sparse is being installed into /home/lovegcy/bin/. Ensure that you have added the path /home/lovegcy/bin/ your $PATH environment variable. Otherwise the system will NOT be able to find the sparse binary.

在Ubuntu上(运行bash shell)，可以通过在.bashrc文件中添加以下行，从而自动为每个新终端添加此代码，如下所示:

On Ubuntu (running the bash shell), this can be automated for each new terminal by adding the following line in the .bashrc file as follows :

$ echo "export PATH=\$PATH:/home/lovegcy/bin/" >> ~/.bashrc
