Linux内核运行稀疏失败 - /bin/sh:1:稀疏:未找到

Question

我在linux内核上运行稀疏.

但它会引发以下错误:

在linux上运行稀疏:
lovegcy @ knltest-VirtualBox:〜/ git_root/linux $ make C = 2
make [1]:对于'all'没什么可做的.
HOSTCC arch/x86/tools/relocs_32.o

/ bin/sh:1:稀疏:未找到
make [2]:*[scripts/mod/empty.o]错误127
make [1]:[scripts/mod]错误2

这是稀疏安装日志:

更多:内核已经编译完毕.

任何人都可以提供一些线索吗？

非常感谢你!

更简单的方法:

首先,sparse从官方渠道下载并安装在主机PC上.

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

从源头构建:

或者,如果您尝试sparse从其源代码构建,那么我们需要确保在运行make install命令后sparse二进制文件存在于/usr/bin/sparse.

这可以通过打开一个新终端并which sparse在其中运行命令来确认.它应该输出类似于以下内容:

$ which sparse
/usr/bin/sparse

在同一终端中,导航到Linux内核源目录并尝试在Linux内核源上make C=2运行sparse.

注意:从您的日志中可以看到sparse正在安装的日志/home/lovegcy/bin/.请确保您添加的路径/home/lovegcy/bin/的$PATH环境变量.否则系统将无法找到sparse二进制文件.

在Ubuntu(运行bash shell)上,可以通过在.bashrc文件中添加以下行来为每个新终端自动执行此操作,如下所示:

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