* Check for bash version 4 or higherQuentin Boswank2024-03-081-3/+3
| | | | | | We use bash 4 features in some scripts Signed-off-by: Quentin Boswank <qubos@outlook.de>
* Remove configure time check for rsyncChris Packham2023-12-181-4/+0
| | | | | | | Now that we're checking for rsync in Kconfig we can remove the check from ./configure. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* provide a workaround for a glibc and GNU make incompatibilityChris Packham2023-07-211-0/+7
| | | | | | | | | | | Versions of GNU make newer than 4.4 trigger a hang in versions of glibc older than 2.31. As distros update to the newer GNU make version we'll start seeing more and more reports of this hang. Fortunately we already carry GNU make as a comp tool so all we need to do is select the right version when needed. Fixes #1946, #1932, #1975 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* Revert "Update requirements: autoconf==2.71 and automake>=1.16"Thomas Petazzoni2023-07-211-7/+7
| | | | | | | | | | | | | This reverts commit 658f5e574f4025655da318fb0b688a394b6ff43f, which was made without any justification, and prevents using crosstool-ng even in decently recent distributions like Ubuntu 20.04 (which has autoconf 2.69). We have tested that ./bootstrap && ./configure --enable-local works fine on Ubuntu 18.04, which uses autoconf 2.69 and automake 1.15, so the existing requirements were enough.

* Switch AC_PROG_YACC to AX_PROG_BISONBryan Hundven2022-10-271-1/+1
| | | | | | | AC_PROG_YACC is kinda buggy. Switch to AX_PROG_BISON from autoconf-archive. Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>

* binutils: Add binutils 2.39Chris Packham2022-08-141-0/+7
| | | | | | | | | | | | | | | https://sourceware.org/pipermail/binutils/2022-August/122246.html Add binutils 2.39 and regenerate patches. 0008-binutils-2.38-vs.-ppc32-linux-kernel.patch is dropped as it has been applied upstream. Add a milestone for 2.39 which will be handy for Loongarch. Binutils now requires bison >= 3.0.4 to build gprofng for x86/aarch64 so we build our own bison when the host bison does not meet that requirement (which appears to be the case on macOS).

* configure.ac: AC_PROG_LEX set to noyywrapChris Packham2022-07-271-1/+1
| | | | | | | | | | | It appears that noyywrap is actually what is needed for kconfig. Particularly on arclinux where the default flex installation does not provide the yywrap function. Fixes #1790 Fixes 015d039e ("AC_PROG_LEX set to yywrap") Signed-off-by: Chris Packham <judge.packham@gmail.com>

| | | | | | | | As described in detail here: https://www.gnu.org/software/autoconf/manual/autoconf-2.70/html_node/Particular-Headers.html#index-AC_005fHEADER_005fSTDC-1 We no longer need AC_HEADER_STDC in configure.ac Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>
* AC_PROG_LEX set to yywrapBryan Hundven2022-06-261-1/+1
| | | | | | | | | | | With autoconf 2.70 and newer, you need to define either `yywrap` or `noyywrap` as an option to AC_PROG_LEX. https://www.gnu.org/software/autoconf/manual/autoconf-2.71/html_node/Particular-Programs.html#index-AC_005fPROG_005fLEX-1 `yywrap` is needed for kconfig.

* configure.ac: bison is required for kconfChris Packham2022-06-131-1/+1
| | | | | | | | | | Make the requirement for bison harder (but not strict). The system bison will be used to build kconf. If the system bison is not GNU bison 2.7 or later crosstool-ng will build GNU bison as a companion tool if necessary (for glibc 2.29 or newer). Fixes #1621 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* configure.ac: Check that patch supports --no-backup-if-mismatchChris Packham2022-01-101-0/+6
| | | | | | | | | BSD patch does not support --no-backup-if-mismatch. When we detect patch check that it supports the option we use. Fixes: #1577 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* linux: Add dependency on rsync for Linux >= 5.3Chris Packham2021-11-301-0/+4
| | | | | | | | | | | As of Linux v5.3 rsync is used as part of the build process. Add Linux 5.3 as a milestone, configure detection of rsync and a dependency on rsync for Linux 5.3 and newer. Add a comment in so that users can tell why they can't select a newer version. Fixes #1628 Signed-off-by: Chris Packham <judge.packham@gmail.com>

* CentOS6 cannot use newer GDB releasesAlexey Neyman2019-03-051-0/+3

* Meet our new companion tool, bisonAlexey Neyman2019-03-041-1/+6
| | | | | | | Which is here courtesy of CentOS6, which only has bison 2.4 - while new glibc requires 2.7. Signed-off-by: Alexey Neyman <stilor@att.net>
* Fix build of glibc 2.29 on systems with obsolete host programsAlexey Neyman2019-03-021-0/+22
| | | | | | | | | | | | - Force building make as a companion tool if host make is older than 4.0 (CentOS 7 currently has 3.82) - Disable 2.29 as a choice if host python is older than 3.4 (CentOS 7 has 2.6 unless python from EPEL is installed) - Python2 emits its version information to STDERR. Ugh. While there, also use the detected host Python for GDB configuration. Signed-off-by: Alexey Neyman <stilor@att.net>

* Add an override for bisonRoman Bolshakov2018-11-071-1/+1

* Cannot ignore 'make install' with automakeAlexey Neyman2018-04-071-17/+1
| | | | | | | | | | | | | | | | | | | | Automake does not allow us to place the hooks before its generated actions, and does not allow us to check MAKECMDGOALS, and does not support a mechanism for disabling make install (such as noinst_SUBDIRS, requested a few times on automake mailing list). The only way I could preserve the current behavior is to have a GNUmakefile wrapper that will convert MAKECMDGOAL into a variable unknown to automake - which seems too convoluted a solution for the problem being solved. Hence the approach is to not override anything for --enable-local. It is now fully handled by selecting different values for CT_xxx_DIR in ct-ng.in; but at the build-system level, all the variables remain the same. We just don't support 'make install' in that case anymore; but the ct-ng in the working copy can be used after a regular 'make' (or 'make all'). Help message for --enable-local updated accordingly.

* Remove special handling of dpkg-buildflagsAlexey Neyman2018-04-071-2/+0
| | | | | | | | Instead, just honor CFLAGS/CPPFLAGS/LDFLAGS as they're passed down from configure. This brings the build process in compliance with the recommended practices. Signed-off-by: Alexey Neyman <stilor@att.net>
* Get rid of sub{lib,doc}dirAlexey Neyman2018-04-071-7/+5
| | | | | | | | | They don't make sense - using same ct-ng won't work with different versions, so they cannot coexist in the same prefix. Also localize other configure variables so that their usage is easier to track. Signed-off-by: Alexey Neyman <stilor@att.net>
