Masahiro Yamada eef8eb4033 kconfig: display recursive dependency resolution hint just once
Commit 1c199f2878f6 ("kbuild: document recursive dependency limitation
/ resolution") probably intended to show a hint along with "recursive
dependency detected!" error, but it missed to add {...} guard, and the
hint is displayed in every loop of the dep_stack traverse, annoyingly.

This error was detected by GCC's -Wmisleading-indentation when switching
to build-time generation of lexer/parser.

scripts/kconfig/symbol.c: In function ‘sym_check_print_recursive’:
scripts/kconfig/symbol.c:1150:3: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation]
   if (stack->sym == last_sym)
   ^~
scripts/kconfig/symbol.c:1153:4: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’
    fprintf(stderr, "For a resolution refer to Documentation/kbuild/kconfig-language.txt\n");
    ^~~~~~~

I could simply add {...} to surround the three fprintf(), but I rather
chose to move the hint after the loop to make the whole message readable.

- Update .gitignore, do not place .gitignore into directories installed

- Remove executable permissions and shebangs from the scripts that are
supposed to be invoked only via ct-ng frontent; prepend them with $(bash).
Despite what showSamples.sh said, it already has some bashisms.
- Remove --with autotools-dev and override dh_update_autotools_config
to avoid having config.{sub,guess} clobbered with older versions
- Install bash completion where Debian (now) expects it
- Update man page to use .\" as the comment delimiter, instead of
undefined macro (."); also, minor text edits.
- Install kconfig.mk without execute permission.
- Remove shell wrappers from 170-localedef-fix-trampoline.patch, we
do not use that for applying patches
- Revoke execute permissions on 210-expat.sh

This reverts commit 7bcf18bfab.
7 years ago
Alexey Neyman 7bcf18bfab Determine whether -E/-r option selects extended regexp
... and then use the right option. See the note in scripts/functions
on where we should use ${foo} and where just 'foo'; this boils down to
whether we can expect the build tools override to be in effect (e.g. in
the actual build scripts) or not (i.e. outside of scripts/build).
While running in scripts/functions, or in scripts/crosstool-NG.sh the
build tools override directory (.build/tools/bin) may have not been
set up (yet, or at all).

Also, modify the installed scripts (populate, xldd) accordingly.

Bryan Hundven 6c49a232a8 configure: Correctly search for tinfo for kconfig
I previously thought that tinfo could only be a link to libncurses in
modern ncurses installations. I was wrong.

Now we check for ncurses, then check for tinfo. If tinfo is a link to
ncurses, it is then not required to link against. But if libtinfo is
providing tgetent, and not libncurses, then we must add it to LIBS as
well.

Also, kconfig shouldn't hardcode -lncurses, it should use what is in
$(LIBS).

Alexey Neyman 5844514e74 Fix samples using GMP 4.3.2.
Some older versions of configure (including the one in GMP 4.3.2)
interpret the $ECHO environment variable as the `echo' utility to
use. CT-NG sets the variable to `:' and exports it if V=0 or V=1
is supplied, breaking the samples using such configure. This currently
includes bfin-unknown-linux-uclibc and powerpc-unknown-linux-uclibc.

Also, correct the description of the V= variable - V=0 is *not* the
default; in fact, default does not correspond to any of the V=[012]
values.

Jason T. Masker 10e1579799 scripts/crosstool-NG.sh.in: patch regex to work with BSD grep
BSD grep does not interpret a null alteration. It complains about an
empty sub-expression, e.g.:

$ grep --version && grep -E '^(# |)CT_' .config
grep (BSD grep) 2.5.1-FreeBSD
grep: empty (sub)expression

This patch replaces the null alteration with a zero or once quantifier
which works with both BSD & GNU grep.

$ grep --version && grep -E '^(# )?CT_' .config
grep (BSD grep) 2.5.1-FreeBSD

Ray Donnelly d2bc2be8db configure: Add --with-gperf option
On OS X, Apple supply an old gperf (3.0.3) with xcode and
xcode commandline tools which causes build failures:

./zconf.hash.c:183:17: error: expected expression
{offsetof(struct kconf_id_strings_t, kconf_id_strings_str2),

.. upgrading to gperf 3.0.4 was sufficient to fix this,
so this option allows the user to specify the gperf
program that they wish to use.

To install gperf 3.0.4 from homebrew, I did:

    brew tap homebrew/dupes
    brew install homebrew/dupes/gperf

.. then passed --with-gperf=$BREWFIX/Cellar/gperf/3.0.4/bin/gperf
to configure

What 'defconfig' really does is save the current .config to a defconfig,
