I renamed it "individual" to not confuse it with the standalone shell. (Which
it isn't compatible with for obvious reasons.) Configure busybox (I did
make defconfig), then run scripts/individual and it'll build an individual
version of each applet in the "build" subdirectory.
Currently it builds 146 and fails to build 104 applets out of "make defconfig".
I haven't taught it about multi-file applets yet (like tar), or the ones where
two applets get built from the same source (for example, zcat is a trivial
variant of gunzip so there is no zcat.c). But here's a start.

the attached patch makes applet list in busybox.links

Currently, they don't appear because they are prefixed
with ENABLE_ in include/applets.h

The configure system's save function edited out sub-menus that wouldn't be
displayed in the current configuration, meaning config.h wouldn't have #udef
entries for those symbols, meaning bb_config.h would have the relevant
ENABLE_ missing instead of defined to 0. This broke the build.
So I fixed it, and then reorganized the applets.c and busybox.c to take
away the warnings this revealed (code that would be optimized out was making
calls to functions that hadn't been prototyped. So I added an #else case
to those #ifdefs to #define the relevant functions to empty macros to
placate the warnings.
I also reorganized the applets.c code to make adding such an #else case less
of a pain (and make the need for prototyping go away by moving the functions
up before they were used, and generally wind up with fewer #ifdefs in
the code by putting all the logic in one place). This resulted in a huge
seeming patch, when most if it just moves code from one place to another
without touching it...
Upside: make allyesconfig and make allnoconfig should both work now.

(I.E. any argv[0] that starts with "busybox" winds up in busybox_main().)
Added testing/busybox.tests which tests the following permutations:
./busybox
./busybox-suffix
./busybox cat
./busybox-suffix cat
./busybox --help
./busybox-suffix --help
./busybox --help cat
./busybox-suffix --help cat
./busybox --help unknown
./busybox-suffix --help unknown
./unknown
Also repair the test suite so ./runtest calls the ".tests" scripts properly.
Note: you can now go "busybox busybox busbox ls -l" and it'll take it. The
new code is pretty generic. I can block that if anybody can come up with a
good reason to...
|
|
Otherwise if you build busybox without a given applet you get the wrong error
message when you call it via a symlink to that applet.
(You also get the wrong behavior; it tries to use argv[1] as the command
name just like busybox does for _any_ unknown, and although I doubt
"echo rm -rf *" is common usage there's no upside and enough downside to
make me nervous.)
This fixes it.

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.
