remove the now unneeded NOTPARALLEL clause
|
|
|
|
|
|
|
|
a) include/usage.h is changed, and
b) after "make clean".
|
|
Rename to CROSS_COMPILE and move its configuration to .config.mak. (Shaun Jackman)
|
|
Experimental.
|
|
- make sure that bbconfig isn't too stupid
|
|
|
|
- move the link flags to cmd_link* so they are printed when requesting verbose output
|
|
- we already depend on sed, so do away with tr. Avoids pulling in yet another
dependency.
|
|
|
|
|
|
- rename check_gcc to check_cc and pass the CC to use as arg#1; peruse check_cc for HOSTCFLAGS
- add and use check_strip
- add checks for {,no-}whole-archive and {start,end}-group LD flags
|
|
- flag .depend as .NOTPARALLEL to workaround bug in make-3.80 and make-3.81
Some more details on the second workaround (i.e. kludge):
make-3.80 silently fails, while make-3.81 is at least self-conscious enough to
admit:
include/usage_compressed.h: .config scripts/usage
# Implicit rule search has not been done.
# File does not exist.
# File has not been updated.
# Dependencies commands running (THIS IS A BUG).
# commands to execute (from `/home/cow/src/bb2/Makefile', line 430):
$(Q)$(SHELL) $(top_srcdir)/scripts/usage_compressed "$(top_builddir)/scripts" > $@
I'm giving up on trying to run the rest of the prerequisites of .depend in
parallel and just (try to) indicate that the prerequisites of .depend are
not to be run in parallel.
While this makes `make distclean defconfig;make -j´ work for me, it is not a
real -- longterm -- solution; FIXME

Development:
bloatcheck - show size difference between busybox_unstripped
/bin/sh: -c: line 0: unexpected EOF while looking for matching `''
/bin/sh: -c: line 1: syntax error: unexpected end of file
make[1]: *** [help] Error 2

busybox_unstripped to busybox_old, build a new version, and "make bloatcheck"
to see a detailed breakdown of the size difference.
|
|
tree doesn't change that.

Currently we have these errors:
./modutils/Config.in: No helptext for 'CONFIG_FEATURE_QUERY_MODULE_INTERFACE'
./networking/Config.in: No helptext for 'CONFIG_IPADDR'
./networking/Config.in: No helptext for 'CONFIG_IPLINK'

* Rules.mak: Ditto.

I encountered a little typo in 'make help' : the prefix was
noted "$prefix" instead of "$(PREFIX)".

defconfig first), and group busybox administrative settings into a sub-menu.

lots of finds doing individual -exec rm.

version of make (3.71.1).
|
|
- no order-only prerequisites; incomplete workaround (see comment in diff)
- no internal variable MAKEFILE_LIST; workaround
- define bar\nfoo:=<long-list> doesn't work; workaround
also:
- reinstate clean, distclean as noconfig_target.
- unconditionally clean libbusybox.so*

landley, that one broke your tar-testing (see below).
To see the issue i was talking about in the comment to rev. 14431, remove the
'P' from ARFLAGS in Rules.mak, then recompile.
You will see undefined references to these symbols:
iplink_main
iproute_main
iptunnel_main
login_main
run_parts_main
These are due to the fact that these applets (named e.g. login.o) clash with
libbb/login.o, for example. So ar sees that we're going to add login.o
(the applet!) and does so. Later on, we add libbb/login.o (just the basename
is used, so login.o). and this libbb/login.o *replaces* the login.o (the
applet!).
I therefor want (you) to rename abovementioned files from libbb to have
a prefix bb_ (e.g. svn mv libbb/login.c libbb/bb_login.c) to avoid these
clashed.
ok?
TIA,
