make headers_install for out-of-tree modules

[Daniel.]

Hi all,

I'm trying  to install headers from out-of-tree module. I've writed
this[1] Makefile. I have Kbuild files with header-y tokens poiting for
propper folders and files. When I run "make headers_install" I got
this[2] error message,

[1] http://pastebin.com/9f3kYT8k
[2] http://pastebin.com/yfi69nUi

Any idea?

Best regards,

Uhh, as I see from docs, this isn't supported,

--- 2.3 Targets

When building an external module, only a subset of the "make"
targets are available.
>From https://www.kernel.org/doc/Documentation/kbuild/modules.txt

So, how can I export ioctl calls defined by an out-of-tree module?

I had the same expectation and it was a sad day when I found myself
having to do it manually in the out of tree makefile, having to handle
__user annotations in particular, as it wasn't possible to call
scripts/headers_install.sh as scripts/unifdef.c wasn't compiled and
available in the various kernel build environment provided by
distribution packages.

PS: please, don't top post reply, thanks.

You get your out-of-tree module merged into the tree and it's
automatically solved for you :)

make headers_install for out-of-tree modules

Hi,

thanks for the replies

Well, I'm using out-of-tree for development, I use it in one tree
while working and on another at home, so I keep my module out-of-tree
at only one repository, and compile against too trees. This is my
header[1], it doesn't have anything special, only ioctl definitions. I
read that this header processing is mainly because of libc and
syscalls integration. Since I don't mess with syscalls and libc stuff
do I need to process them too? When and why this header processing
applies?
