doc/BUILD.changes hat geschrieben:Configuration options:
--[enable|disable]-flashrules (replaces
--with-targetruleset=[standard|flash]). As opposed to previous versions,
building yadds and building flash images do not exclude
one another. Using --enable-flashrules targets for creating flash
images are included in the generated Makefile, otherwise not. By
default they are enabled. If enabled, all compilation is
using
the flash-optimized compilation flags (no debugging info, stripped,
compiled with -Os (optimize for size). Other than that,
--enable-flashrules has no disadvantages, and can normally be left
on. Using --with-targetrulset now gives a warning error; in the future it
should be completely eliminated.
--with-rootpartitionsize=SIZE gives the possibility to build (cramfs-,
squashfs-) images with non-default root partition size. The size of
the var-partition is automatically computed to use all remaining
flash space, i.e. everything not used by the other partitions. Default is
0x660000 (as before). This number should be a multiple of the erase
size, presently 0x20000. Ignored (while meaningless) by jffs2-images.
--with-serversupport=DIR: New option. Build template files for
/etc/dhcpd.conf, /etc/fstab, /etc/hosts, and /etc/xinetd.d/tftp for
a Linux server.
--with-logosdir=DIR: New option. Picks logo files from this directory,
if found.
--with-ucodesdir=DIR: New option. Installs ucodes from this directory, if
found. (An image containing Betaresearch ucodes may not legally be
distributed.)
--enable-maintainer-mode still exists, but does nothing explicit. (It
is passed on to invoked configure's, and enables automatic
re-invocation of configure if necessary, so it makes sense.)
--with-checkImage=[none,rename,warn] How/if to invoke checkImage. If
`none', do nothing. If `rename' created images are checked by by
checkImage, and if checkImage complains about the file (which may or
may not mean that the image will not run), it is renamed to
*_bad. If `warn', a zerosize *_bad-file is created, to warn the
user. Requested by dietmarw.
--with-updatehttpprefix=URL optional URL containing the URL of a
directory with update images.
Removed configuration option:
--with-hostruleset=[standard,cygwin]. This was not working, and is not
the right method. configure should take care of this. (Don't confuse
this with "removing support for Cygwin"! Building with Cygwin should
preferably be supported, but --with-hostruleset is not the way!)
--[enable|disable]-libcrypto has been eliminated. libcrypto is not
built by default; no reason to treat it differently from other
optional libraries.
Removed program:
fakeroot has been eliminated.
FILENAMES:
Naming system: A file system image is generally named
[root,var]-[neutrino,enigma].[cramfs,squashfs,jffs2]. Full images have
names like [neutrino,enigma]-[cramfs,squashfs,jffs2].img[1x,2x]. The
semantics is hopefully obvious.
The previous version of this work used the notation "jff2fs". It has
been replaced by "jffs2" ("journalled flash file system 2").
Makefile[.am]:
Restructuring to make more target-driven (but still not
perfect).
Customization-hooks: Many rules calls customization script, if present.
Now builds root/.version file that can be parsed by neutrino.
For neutrino, installs plugins tuxmail, tuxtext, tuxcom, vncviewer and
fx2/*. For enigma, also installs enigma/*.
The partitioning table file linux/drivers/mtd/maps/dbox2-flash.c is now
generated from an m4-file, for all the different configurations.
Changed targets:
all: different semantics
busybox: replaced by $(targetprefix)/bin/busybox (for yadd) and
$(flashprefix)/root/bin/busybox (for flashing). For this, configuration
files busybox.config and busybox-flash.config merged to
busybox.config.m4.
New (public) targets (see doc):
serversupport, everything, yadd-[all,none,neutrino,enigma,lcars],
dboxflasher, bare-os.
Cleaning targets:
New and/or changed cleaning targets: flash-clean,
flash-semiclean, flash-mostlyclean, clean, mostlyclean. Cleaning
targets like clean and mostlyclean now works sensibly.
POSSIBLE PROBLEMS:
-- Due to the new dependencies, sometimes rebuilds too much. (Should
be fixed now)
-- Neutrino contains ($(appsdir)/tuxbox/neutrino/src/gui/update.cpp)
stuff like #ifdef SQUASHFS. (FIXED)
TODO:
-- Support kernel 2.6. Can this be
without building the kernel
version into the CDK environment?
-- Neutrino and Enigma should be installed (in flash) with something like
$(MAKE) -C $(appsdir)/tuxbox/neutrino install prefix=$(flashprefix)/root/...
(DONE)
-- Possibly restructure Makefile.am, with non-essential stuff in
included files,...? (DONE)
-- Merge all the u-boot-*.dbox2.h files (or at least the ones we are
using) into an m4-file. (Like I did with the busybox.) (DONE)
-- Ditto for rcS[.insmod] (DONE),
-- and possibly also for the kernel .config? (Only for 2.6.)
-- Check dependencies carefully, to minimize unnecessary rebuilds. (DONE)
-- teach neutrino's flash function to recognize my file extensions
(DONE)
-- Some rules (e.g. %/lib/ld.so.1) still look awful (DONE, basically.)
-- Sensible clean-targets (DONE).
-- Move all fonts to $(fontdir) (new variable).
NICE THINGS TO HAVE:
-- download/build mkcramfs, mksquashfs, mkjffs2, mkfs.jffs2 (DONE)
-- Really fix the "Kein System"-problem (that checkImage is scratching
on). (HARD)
-- At least optionally, it should be possible to build an absolutely
minimal system. (DONE, see target bare-os and yadd-neutrino-micro)
-- Generate md5-checksums (DONE)
-- configure should be picky on program versions (DONE)
-- yadd (!= cdk) targets. "Images" for disk based systems.
-- smarter font handling.
DISADVANTAGES in comparison to old version:
-- Needs more space to build,
-- May rebuild more (while "oldmake" often "cheats").
-- No support for images with more than one GUIs.
(or even just "flash-lcars-jffs2-2x" would be nice !)
