Difference: the kernel-devel package only contains the kernel header file and makefile required for the kernel development environment, while the kernel-Souce contains all the kernelSource code.If you only want to develop your own modules, you only need to reference the corresponding kernel header file, so only the devel package is available. If you want to modify the existing kernel sourceCodeAnd re-compil
When compiling the kernel in ubuntu16.04, an error occurred using make menuconfig, saying that no ncurses-devel was installed.

Sending a script a few days ago is very slow. Using Time can only know the total time, but cannot confirm the reason. We found that devel: nytprof is a very good tool.
If you have the root permission, then:

If you do not have the root permission, then:
Create a folder in the home directory, such as/home/username/perl. Local.
