Hi Roman, sorry if you get this twice. first mail did not show up.
I have been working on integrating lkc with kbuild.
Here is the result.
Rules.make
- Added infrastructure to support host-ccprogs, in other words
support tools written (partly) in c++.
scripts/lkc/Makefile*
- As kbuild does not distingush between individual objects,
used for a given target, but (try to) build them all, I have
found a solution where I create one Makefile for each executable.
I could not see a clean way to integrate this in kbuild, and finally
decided that in this special case a number of Makefiles did not
hurt too much.
flex/bison
- Prepared for "_shipped" files.
Rename lex.zconf.c to lex.zconf.c_shipped etc. in the version
reday to go in the kernel.
