scripts/config from distclean to clean) with a sed consolidation that's
been in my tree for a bit, and switching the GPL boilerplate to just point
at LICENSE.
obvious (and less side-effect prone in strange build environments) BB_CONFIG_H.
Yeah, I know Erik ripped it out of our copy of menuconfig (which is a good
thing), but that doesn't fix people whose headers have it inherited from
linux-kernel headers or old versions of uclibc, and Erik's fix could easily
get forgotten and reverted the next time we update menuconfig anyway...
infrastructure, the compiler isn't smart enough to replace const static
int with the constant, and allocates space for each set of them,
bloating the executable something fierce. Oops.
So now, we #define ENABLE_XXX to 0 or 1 for each CONFIG_XXX (which
is still there so the 1000+ #ifdef/#ifndef tests don't have to be
replaced wholesale). Changed the test instance in networking/ifconfig.c
to use this.
Rob Landley, and others.
Currently CONFIG options are defined or undefined, so we chop out code with
#ifdefs, ala:
#ifdef CONFIG_THING
stuff();
#endif
This creates a new header file, bb_config.h, which sets the CONFIG entry to 1
or 0, and lets us do:
if(CONFIG_THING) stuff();
And let the compiler do dead code elimination to get rid of it. (Note: #ifdef
will still work because for the 1 case it's a static const int, not a #define.)

ahem. It looks like i'm slightly late with it but... Here's a little
addition to make 'make O=/some/where PREFIX=/some/where/else install'
work. Sorry for delay :(

Hi!
I've created a patch to busybox' build system to allow building it in
separate tree in a manner similar to kbuild from kernel version 2.6.
That is, one runs command like
'make O=/build/some/where/for/specific/target/and/options'
and everything is built in this exact directory, provided that it exists.
I understand that applyingc such invasive changes during 'release
candidates' stage of development is at best unwise. So, i'm currently
asking for comments about this patch, starting from whether such thing
is needed at all to whether it coded properly.
'make check' should work now, and one make creates Makefile in build
directory, so one can run 'make' in build directory after that.
One possible caveat is that if we build in some directory other than
source one, the source directory should be 'distclean'ed first.

* Changed so that not only links but /bin/busybox might be deleted.
* When double quoted PREFIX is defined by `.config' is used,
`make uninstall' does not work correctly.
When default PREFIX `pwd`/_install defined by Rules.mak is used,
similarly it does not work correctly.
Changed $$PREFIX into $(PREFIX) in order to fix this.
Patch by Hideki IWAMOTO
modified Kbuild system I put into uClibc. With this, there should be no more
need to modify Rules.mak since I've moved all the interesting options into the
config system. I think I've got everything updated, but you never know, I may
have made some mistakes, so watch closely.

#49: I found one memory overflow and memory leak in "ln" applet.
Last patch reduced also 54 bytes. ;)
#50: I found bug in loginutils/Makefile.in.
New patch have also new function to libbb and
aplied this to applets and other cosmetic changes.
- Made a new dir loginutils
- Moved all applets from pwd_grp to loginutils
- Added new applets su.c login.c to loginutils
- Made a new dir libpwdgrp
- Moved everything from pwd_grp/libpwd_grp there
- Added shadow.c to libpwdgrp
- Removed dir pwd_grp
- Added usage strings for login and su to usage.h
- Changed main Makefile to reflect the dir rearrangements
[Parts of this patch may overlap with my other two patches]
the busybox development tree. This eliminates the use of recursive make, and
once again allows us to run 'make' in a subdirectory with the expected result.
And things are now much faster too. Greatly improved IMHO...

bug with chroot. I've had the package uploaded but perms set to
000, so I am going to re-tag things and re-cut the release. Folks
who pulled from CVS in the last 30 minutes with just have to cope.
