would you pls tell me the details, :)
You added V=1 to the kernel build flags which causes the build system to show the commands it is executing.
Then you find the specific command you want to see the pre-processed output for; copy it, add -E and run it by hand.
That's it!

hi all,
i'm porting the mali driver on the latest linux kernel. but it cannot work. firstly, i thought maybe i should check that the preprocessor output be the same under different linux kernel verison.
as gcc could use the -E options to get the preprocess output. after reading in the Document/kbuild/kbuild.txt, modules.txt. KCPPFLAGS=-E was set in the KDIR/Makefile, but the preprocessors output couldn't get in the *.o.
is that right? or is there any quick way to get the preprocessor output.
I do it the very dumb way!
I build with V=1 and then copy the resulting line, slap on a -E and run it outside of make.
