2018-07-10kconfig: display recursive dependency resolution hint just onceMasahiro Yamada1-2/+6
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.

2017-02-14Determine whether -E/-r option selects extended regexpAlexey Neyman1-1/+1
... 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. Signed-off-by: Alexey Neyman <stilor@att.net>

2015-11-15configure: Correctly search for tinfo for kconfigBryan Hundven1-1/+1
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). Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>

2015-10-30Fix samples using GMP 4.3.2.Alexey Neyman1-5/+5
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. Signed-off-by: Alexey Neyman <stilor@att.net>

2013-09-14configure: Add --with-gperf optionRay Donnelly1-1/+1
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.

The kconfig frontends are currently instaleld as source files. This is a remnant of the early times, when I wanted a single installation of crosstool-NG to be shared across multiple machines, potentially of different architectures.
