[LLVMdev] HELP: Clang options needed in command to compile device driver into linux module.
Wow that's to much output information. Maybe I can put it in this way. Could you tell me the clang option that can include the linux kernel headers??? Something like "clang -O3 -isystem /lib/modules/`uname -r`/build/include -emit-llvm hellomodule.c -c -o hellomodule.bc" Thank you! -- 祝好! 甄凯 ------------------------------------------------------------------------------------------------------ 2012-04-12 ------------------------------------------------------------------------------------------------------ Name: 甄凯(ZhenKai) Homepage:http://www.renren.com/262729393 Email: zhenkaixd at 126.com or 846227103 at qq.com TEL: 15810729006(Beijing) Address: Room I-406, Central Building, Tsinghua University, Beijing, China. 100084.

[LLVMdev] HELP: Clang options needed in command to compile device driver into linux module.
BTW, the Makefile is as folllow, CC := gcc obj-m := hellomodule.o KERNELDIR := /lib/modules/`uname -r`/build PWD := $(shell pwd) modules: $(MAKE) -C $(KERNELDIR) M=$(PWD) modules Can I use an option of clang to specify the KERNELDIR ,etc?
