asm/types.h Header file wont get generated while building uImage ?

asm/types.h Header file wont get generated while building uImage ?

[Prabhakar Lad]

Hi,

Usually for building uImage I follow this steps,
1: do a clean distclean
2: make ARCH=arm CROSS_COMPILE=xxx   xxxdefconfig
3: make ARCH=arm CROSS_COMPILE=xxx  uImage

This used to work until 3.8, for 3.9 I see the following error:

  HOSTCC  scripts/genksyms/parse.tab.o
In file included from include/linux/types.h:5:0,
                 from include/linux/mod_devicetable.h:11,
                 from scripts/mod/devicetable-offsets.c:2:
include/uapi/linux/types.h:4:23: fatal error: asm/types.h: No such
file or directory
compilation terminated.

Well this get fixed if do  make ARCH=arm
CROSS_COMPILE=arm-none-linux-gnueabi- headers_install
and the build the uImage.

Is it the same way now its going to be followed or is it I am missing
something ?
(For  reference I have used da8xx_omapl_defconfig config when I faced
this issue)

Does that help?

It's rather difficult to be certain as I've only seen it in our daily
automated builds but I forced the failure on my local PC by adding
'sleep 2' to the rules in scripts/Makefile.asm-generic and doing a build
with -j4. Then after applying the below fix I couldn't reproduce the
failure. I'll add the fix to the trees our automated builds use and
report if I see any other issues but I don't anticipate any.

Thanks for looking at this.

[PATCH] kbuild: generate generic headers before recursing into scripts

[Andreas Schwab]

The headers are now needed inside scripts/mod since 6543bec
("mod/file2alias: make modalias generation safe for cross compiling").

I think it has sufficiently been tested by now.

Thanks a lot, I added it to kbuild.git#rc-fixes.
