[LLVMdev] How to compile this linux-driver like programme into .bc file?

[15102925731]

Dear Chen,
I tried the command you told me. It turns out that clang use -I option rather then -isystem.
But after I included the init.h file, it fired at me that "asm/processor.h" is not fount. Then I included that file
using -I option and some other files were said not found! It's like I opened a can of worms...

I can still continue to include the file that is said not found. But is it the right way ?

Thank you!


clang -O2 -DMODULE -D__KERNEL__ YOUR_MODULE.c \
>>  -W -Wall -Wstrict-prototypes -Wmissing-prototypes \
>>  -I /lib/modules/`uname -r`/build/include \
>>  -emit-llvm -o YOUR_MODULE.bc
