merge mk/

copy trunk/freewrt r3264 into a new branch for making the nfo system
because upgrading the old adk branch would be a hell more work

part Ⅱ – simplify busybox config, ok wbx@
from now on, you can select a smaller and a fuller busybox, like mksh;
if you want fewer applets, hand-edit the config, we won't prevent you,
but shan't support it in the ADK any more; if you want more applets,
please talk to me and I'll see if they can be included in the list

we still have a problem regarding duplicate binaries (ip, free, tar, …)
which could be solved with dpkg diversions if ipkg supports them;
for now just consider busybox a non-upgradable package if you have any
of these installed

if mkdir fails here, we have a dangling symlink; working
symlinks don't fail, so revert the last change again

grml…

I like to fix things I have no ideas of… (sarcasm included)
this should fix wbx' allmodconfig target, retaining the choice
which target to use (maybe it keeps more from old .config tho)

• base-files: fix .ipk file name
• build.mk: if FWRT_PACKAGE_BASE_FILES=y also create build_mipsel/root
  (for chroot build_i386/root/)

add experimental support for nokernel targets (mips and i386 for now)
requested by wbx@

if something doesn't work right or you want to build packages for other
arches (say, arm) just tell me and I'll add them.

• 1.0 -> scripts/param.h, paxmirabilis: MFC the new version from trunk
• both 1.0 and trunk: implement “make targz”, “make tarbz2”
  (I like the gzip(1)d versions better though)
• 1.0 -> package/config/Makefile: quieten the “clean” target to be consistent

the treebreaker ☺

overhaul the fetch'n'checksum system to be more bsd-like
• make fetch, make checksum supported
• future expansion possibilities already prepared:
  – more distfiles than just one
  – check sizes of downloaded files (size matters!!!!!111)
  – more hashes than just MD5
  – recursive fetch/checksum targets
  – PERMIT_{SOURCES,DISTFILES}=Yes/«reason» – licence issues
• download.pl dies

quirks:
• GNU make only has a poor excuse for a .for loop
• some things (esp. toolchain and target/linux) now have
  a ${WRKDIR} where they didn't have it before
• ${WRKDIR}/.checksum_done – no comment… it was necessary
  because otherwise everything will get rebuilt every time
  (did I mention that GNU make sucks?)
• I had troubles tracking the dependency problems down
  because GNU make, unlike BSD make, doesn't have good debugging
• DISTFILES -> FULLDISTFILES
• DL_DIR -> DISTDIR
• PKG_SOURCE -> DISTFILES
• PKG_SOURCE_URL -> MASTER_SITES
• no @SF and @GNU any more, use BSD network.template syntax
  (feel free to add more master sites)
• GNU make doesn't really strip whitespaces from variables…
  (did I mention how much better BSD make is?)
• echo 'LOCAL_DISTFILES=/path/to/distfiles' >>${TOPDIR}/prefs.mk
  will save the need to download 'em, Closes: #102
• MASTER_SITES now *must* have the trailing slashes (there may be
  a few that don't and a few with double ones, please fix them)

I've tested that a normal build (unchanged .config from the default) works
on GNU/Linux. There's definitively room for improvement, but most of that
will come with the NFO system only. Fixes appreciated.

fix allmodconfig

I consider it useful to create a directory before using it.
Oops.

shaddap

optimise

hack to make new “make wconfig”, developer-only, to generate Config.default
feel free to improve

remove target_clean, it can't do what it appears to do since it removes the di-
rectory where all the compiled IPKs are stored, and it's not documented anyway

after menuconfig, if certain options have changed, advise the user to
run make clean; ok wbx@ tha@

order error, my bad, oops

run some more scripts with ${MBSH}

by request of wbx@:

sort out the mess we had in ${TOPDIR}/staging_dir_${ARCH} and introduce
some new variables:
• ${STAGING_DIR} stays the same, but has a different location now
• ${STAGING_TOOLS} is where executables for the host system go
• ${STAGING_PARENT} is ${TOPDIR}/cross_${ARCH} and has three (at
  the moment) subdirectories: host (i.e. STAGING_TOOLS), target
  (i.e. STAGING_DIR) and pkg (used by package.mk, pkg-bottom.mk)
  but is an internal-use-only variable - please don't use it.

this builds through with a non-default config; more testing will follow

*tada*
complete rework of the kernel and kernel module build process.
more modular, very fast and simple (perl free implementation TM)

 * only choosen drivers are compiled in the ADK, significant faster
   compiles (just 10 minutes for a basic image on my X40 notebook for
   a WL500gp)
 * if the user changes something in the ADK, thats not a problem, new
   drivers are automatically compiled on next make run
 * only one simple "kernelconfig" for every board-kernel combination
 * two kind of configuration symbols:
   - FWRT_KERNEL prefix, for kernel features without packages
   - FWRT_KPACKAGE_KMOD prefix for kernel features or drivers with packages
 * very simple to add new drivers to the ADK, just add stuff to 
   target/linux/config/Config.in.* and mk/modules.mk
 * rebuild of firmware images without make clean if you change model/board
   (nearly, one bug with base-files still exist)
 * autogenerated ipkg control files  
 * first cleanup of special netfilter/iptables scripts (netfilter.mk is
  obsolete)
 * New menuconfig point ADK (for ccache, toolchain stuff, prefix,...)
 * package collection is disabled for now, it seems unmaintained. it is better
   to only have this in WIB, in my point of view
   
What is missing:
 * pcmcia support and tests on Linksys WRT54G3G
 * ip6tables 2.4/2.6
 * ebtables for 2.6
 * iptables package 
 * dependencies for shorewall/fwfirewall/iptables package
 * documentation for the developer handbook

Please test and report bugs!
 

this can use mksh too, but the speedup is almost none – most of the time,
it's spent on md5sum or tar

time to break trunk. 

* update to OpenWrt brcm-2.4 patch, wl driver and diag driver
* fix failsafe mode to use new hotplug method
* rework of mk/kernel-build.mk to use .config instead of stampfiles
* simplify mk/kernel*.mk to use $(FS) instead ifeq/else crap

a lot of small stuff.

tested and verified to boot at least on 
- Netgear WG634u
- Linksys WRT54GS v1.0
- Asus WL500gP

Only basic lan and wlan stuff (none encryption, wep) are tested.

PLEASE update only on NON-PRODUCTIVE routers with serial access.
HELP to test the new backend code for BRCM-2.4!

why were we still using the python ipkg-make-index even if we
already had a shell one and weren't scan-tools.sh'ing for python
existence any more? right, because it had bugs…

while here, remove the executable bit from the script and call
it with the proper shell, convert to bash, fix output to be
about the same as from the python script

errors from the python script aren't fatal

for allmodconfig and snapshotconfig:
* reset runtime options and ccache to defaults, too
* run "oldconfig" after the restore script

note: Config.defaults is out of date, please regenerate!

be a little more verbose, agreed wbx@

portability fix

add “oldconfig” target, thanks to nbd@openwrt for the hint
(untested)

if FWRT_PACKAGE_BASE_FILES=m we have allmodconfig; don't even
try to build an image in that case

mv package/config to tools, where it belongs to, because a host tool

toolchain and tools do, ironically, not depend on the .cfg/ dir
to prevent e.g. make prereq to invoke it (unsure about make cleandir);
if we should ever build different toolchain (e.g. compiler)
depending on config options, user *must* do make cleandir
(no change to current behaviour!)

merged from branches/common-adk 1310:1685

the following packages are not converted yet:
* alsa

additionally, freeradius doesn't compile.

happy fixing :P

activate snapshotconfig

missing restore by target snapshotconfig

Introduced a new make target `snapshotconfig'.

This target is quite equal to the well-known `allmodconfig', 
with the extension that all possible target devices are selected
at the same time. This leads to also enabling packages which depend
on certain target devices, what is useful for snapshot builds.

Finished the "allmodconfig" target. As `conf' is quite stupid, with flag
"-m" it selects just everything, also every Busybox feature. This leads
to at least one broken package, so I wrote a little script replacing
config symbols by pattern, taking the default from .defconfig (which I
updated using `rm .config; make menuconfig (just save); mv .config
.defconfig`).
Also corrected a mistake regarding Fuse (sneaked back in with the last
update).

Enabled the well-known "allmodconfig" target.
The idea is merely to build something that fits everywhere,
but rather for testing builds including everything. (This
way one can deselect senseless packages, like e.g. busybox
which is totally useless with everything enabled.)

Also synced Config.in.collections with the one from 1.0.

new target: allnoconfig - creates a config with everything disabled

apparently dead code - .config.cmd does nothing
might fix PR #118 and open different can of worms

remove autobuild and snapshot targets. snapshots and releases will be done with ib.sh

PR #86

revert the bad idea, if ncurses.h is missing you do not see the problem otherwise

merge wbx-target-cleanup to trunk.
- mk directory for some top level makefiles (build.mk,vars.mk)
- add a separate configfs partition to all models, 128 kb big
- add model and platform specific startup files and kernel configs
- delete target/linux/package, add all addon kernel packages to packages
- simplify target/linux/brcm-2.4/Makefile, abstraction to mk/ comes later
- add target/image directory, place where the different images are created
- default off for all extra packages, be sure that you enable all packages
  you need to get a dsl-capable router. snapshots will be created by a specific config which contains all needed stuff (iptables, pppoe, pptp, haserl, webif)

change build.mk to mk/

change build.mk to mk/

make a branch for cleaning up the target dir to a more clear and simple state

realizes autobuild target, non-interactive

add autobuild, still busybox need to be excluded in any good way. no idea for that at the moment. remove unused stuff.

by request of wbx@ add a "licence boilerplate" which can (or should,
or ought to) be added to (almost) any file in the repository, to pre-
vent companies who only check out part of the sources from thinking
it's unlicenced, public domain or whatever.

Please use the template as shown in build.mk or here:

----- cutting here may damage your screen surface -----
# $FreeWRT$
#-
# This file is part of the FreeWRT project. FreeWRT is copyrighted
# material, please see the LICENCE file in the top-level directory
# or at http://www.freewrt.org/license for details.

----- cutting here may damage your screen surface -----

at the top of the file (after a shebang line, if required).

Both this "boilerplate" and the according change to the website
have been okay'd by wbx@ as well as this textual change itself.

hide some warnings and output

we need install-lbin before .config exists, too

as discussed with wbx@ some 2-3 weeks ago, change
the BR2_ prefix to FWRT_

tested with a standard build (only the squashfs
image since the jffs2 didn't get built)

add a by-package prerequisite check

idea by wbx@, code by me

move tools like sed, trx, lzma, which does not belong to the toolchain (gcc,binutils,gdb,libc) to a separate directory, all stuff is compiled with the host compiler

add a short notice after configuring the system, suggestion by rob on the way to stuttgart, hacking in the train ;)

- add hardware profiles, you can choose between different
 hardware models
- add some alsa patches
- remove default stuff

* instead of using a $(VARS_TO_PASS) write the variables into a
  *.mk include file, so that people can cd to some package direc-
  tory and invoke gmake directly
* fake OpenBSD as uname for MirBSD, so that we get a little further
  in the build process there (stops at linux requiring bash now)

Tested with a full build (standard config) on Linux.
Invoking gmake in a subdirectory *not* tested, but
that didn't work before at all, so it's not a problem.

uClibc is not part of the toolchain, even if it's
contained in the toolchain/ directory, so it doesn't
build with CC=$(HOSTCC), change that and don't pass
it the variables (even if CC=$(TARGET_CC) is passed,
it doesn't build - but then, uClibc's build system
is so broken in other regards...)

Full build (make v) succeeded on GNU/Linux:
-rw-r--r--    1 tg freewrt 4706440 Jun 13 14:32 make.log

Didn't attach the build log because of its sheer size ;)

Bug catched by wbx@

provide sensible defaults (-O2) for systems with no default CFLAGS
tested on lunox

note: this also, as a not unwelcome side effect, changes the
default flags used for builds from "-g -O2" to "-O2" on the
standard GNU installation (and "-O2 -pipe" on OpenBSD, I
think). More flags (e.g. debugging) can and will be added
later.

Correctly determine HOSTCC and HOSTCFLAGS (from host make)
and pass them as CC/CFLAGS to the toolchain as well.

Now this at least goes as far as I suspected the first
breakage would be (on MirBSD) - autotools.

Detecting works by invoking $(MAKE) with a BSD-specific
makefile and just using $(HOSTCFLAGS) if that fails.
This works better on OpenBSD too, FWIW.

cosmetic changes to Makefile/build.mk
remove configtest.pl
cosmetic changes in freewrt/toolchain/sed/Makefile, add md5sum

change target distclean to also remove the download area
(distclean = "as clean as if we were making a distfile")

new target cleandir removes everything removed by distclean
except the configuration and downloaded distfiles
(cleandir = clean + toolchain directories)

removed target dirclean, replaced by ordinary clean target
(clean = clean packages, bindir, builddir)

ok wbx@

Initial cut at supporting FreeWRT builds under other operating
systems (MirOS BSD, OpenBSD, probably the other BSDs as well;
Mac OSX and Cygwin to come)

The basic idea is:
* the old GNU make "Makefile" is renamed to "build.mk"
* a wrapper Makefile which uses neither GNU nor BSD make
  features calls GNU make with -f build.mk
* the wrapper Makefile also checks for prerequisite
  tools (as of now: existence of gmake and md5sum)
  and their versions (not yet, but that's why it's
  being used on GNU/Linux as well)
* scripts/md5sum.bsd uses BSD cksum(1) to generate
  GNU md5sum compatible output (only when the arguments
  are files; no options are supported)
* GNU make is symlinked into ./lbin/; md5sum.bsd is
  copied there if needed; ./lbin/ is prepended to
  $PATH for gmake -f build.mk invocations
* make distclean removes prerequisites (and lbin)

change description title

make clean removes bindir

disable toolchain options, dangerous settings, some OpenWrt -> FreeWRT conversion, remove some error messages about .defconfig

add OpenWrt trunk revision 3830.
