symbol (switched on to remove now: test your apps to make sure they _don't_
do this, because as some point we should just yank it), fixup head/tail/fold.
Also tweak "make allyesconfig" so anything starting with CONFIG_DEBUG gets
left switched off. Possibly other things we want to put in the debug menu?
Very unreliable as e.g the ld check will see the flags supported by each emulation, not just the active one.
good enough for now..
Fix would be to crate one or more dummy .c files and accually try if a flag
works.
the attached patch makes applet list in busybox.links
correctly include tr and watchdog.
Currently, they don't appear because they are prefixed
with ENABLE_ in include/applets.h
it's going to be used. (I'm guessing it doesn't work with newlib.)
The other one is from me: allyesconfig shouldn't enable devfs because that
changes all sorts of unrelated stuff (like /dev/loop0->dev/loop/0), which
can come as a bit of a surprise. (It's still there, but you have to go into
menuconfig and select it manually.)
- add some filesystem operation wrapper variables for use in the makefiles and
pull them in early in the toplevel makefile
- use the cross-toolchain for "make sizes"
to test, checkout the source (let's assume /scratch/src/busybox), then
mkdir /tmp/bb ; cd /tmp/bb
make top_srcdir=/scratch/src/busybox O="$(pwd)" -f /scratch/src/busybox/Makefile allyesconfig check
- default to O=$(pwd) if no O was specified. Now you can just specify
the top_srcdir (without O=/somewhere) to create the obj-tree in pwd.
- make "make configtarget buildtarget" work. Previously this didn't
work due to how HAVE_DOT_CONFIG was evaluated. Two separate steps were
needed before, e.g. make config ; make busybox.
- remove some unneeded variables from Rules.mak (BB_SRC_DIR from Mr.
ldoolitt@recycle.lbl) which suggest that the stuff fixed above
didn't work before.
- move selinux libraries to where they belong (from Makefile to Rules.mak)
- update the docs to mention svn instead of cvs and provide an example
for building out-of-tree in INSTALL.
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.)
