..." The problem is you wish to link in the linux kernel headers at "install" time. The problem I see is that the linux kernel headers are C source files, so how is that going to work? You need a C compiler to understand the Linux kernel headers.

Just out of curiosity, what would be the main benefit of this approach vs DKMS which is already widely used ?

Hi, First of all, I didn't study on compiler too much, I'm a Linux kernel developer, Now I have one idea about compile kernel module by using llvm framework. In Linux world, traditionally compile Linux kernel module only have one way: compile it to machine code directly, deploy to target machine, then run it in target machine. This have some problem from long term view, especially

Hi, Is it possible to link native codes generated by different compiler? the usecase could be: Linux kernel compiled by gcc want to load kernel module compiled by Clang (I know there have some problem to compile kernel by Clang currently, but ignore those problem in here) I just concern about the call conversion problem, and compatibility between gcc and clang. Thanks .jovi

I checked DKMS you mentioned, basically DKMS is just a ko and its sources management tool. It's not easy to deploy ko source into target machine, and it's more
