[Buildroot] Buildroot fail to build when configure for dev managment: dynamically with udev

[Martin Peevski]

     Hi,

     I tryed to build Buildroot with only rootfs, I have already built 
Kernel image. Use external toolchain for the building. I configure 
Buildroot for dynamically /dev managment with udev but during udev 
building I got the following errors:

src/udev-builtin-input_id.c: In function 'test_key':
src/udev-builtin-input_id.c:165: error: 'BTN_TRIGGER_HAPPY' undeclared 
(first use in this function)
src/udev-builtin-input_id.c:165: error: (Each undeclared identifier is 
reported only once
src/udev-builtin-input_id.c:165: error: for each function it appears in.)
make[4]: *** [src/udevadm-udev-builtin-input_id.o] Error 1
make[4]: *** Waiting for unfinished jobs....
make[3]: *** [all-recursive] Error 1
make[2]: *** [all] Error 2
make[1]: *** 
[/home/martin/Desktop/sam9x5-linux-sources/rootfs/build/udev-182/.stamp_built] 
Error 2
make: *** [all] Error 2

      Can you, please, give me some advices?

Hi Martin,

what version of kernel headers the toolchain uses? Most likely to 
problem will be around the kernel header version...

Hi,

yes, in this case it comes from the toolchain itself, sou you have to 
check it in the toolchain.

Hi,

depends on the toolchain... just look around in the toolchain's directory.

PS,
let's try to stay on the maillist, maybe others are interested as well...

If Martin is using the external toolchain backend, then he cannot check
anything related to the kernel headers version in the menuconfig.
External toolchains are pre-built toolchains, so Buildroot just uses
them as-is, you have no way of changing the Buildroot version.

Martin: your external toolchain is using too old kernel headers to
build udev. So your options are:

 *) Use a more recent external toolchain that will have more recent
    kernel headers.

 *) Add a patch to udev that defines BTN_TRIGGER_HAPPY to the correct
    value when it is not already defined by kernel headers.

BTW, which external toolchain are you using?

Thanks,

Thomas

Thanks, Thomas! I use arm-oe-gnueabi- toolchain. Can you explain how to 
add a patch to udev to correct the problem?

I'm afraid of using another toolchain because I compile the Kernel and 
the rootfs separately.
