* build: prereq detect Python 3.10 for `python3` binaryPaul Spooren2021-10-101-2/+2
| | | | | | | | | | While the binary `python3.10` is correctly detected by the build system the default `python3` binary is currently not detected if pointing to a Python 3.10 installation. Fix this by extending the grep regex. Signed-off-by: Paul Spooren <mail@aparcar.org>

* prereq-build: require python3-distutilsAndre Heider2021-08-211-0/+4
| | | | | | | | | | | | | | | | | | | | | | | Debian and Ubuntu ship a python3-minimal package which does not include the distutils module. This is not supported by upstream and can be considered a broken python distribution. In practice, many scripts depend on said module, and this is a reoccuring pain point for building various OpenWrt packages. Require and check for said module, enough time has been wasted on this.

* Extend checks on build prerequisites for building OpenWRT coreBas Mevissen2021-05-081-1/+12
| | | | | | | | | | | | | OpenWRT requires a number of Perl modules to be installed. It wasn't checking on all of them. This patch adds checks for Perl FindBin, File::Copy, File::Compare and Thread::Queue modules. Failing to install these, will have the build break at some point. By adding these to the prereq-build.mk script, they are checked on forehand. Tested on a Fedora 33 and 34 (beta) that was freshly installed. Fedora appears to break up Perl modules into small packages that need to be installed for the build to succeed. Signed-off-by: Bas Mevissen <abuse@basmevissen.nl>
* build: add GNU install to prerequisitesKevin Darbyshire-Bryant2021-03-241-0/+4
| | | | | | | | | | | | | | | | The recent removal of usbutils from core and replacement by hwdata in packages has exposed hwdata's requirement for certain GNU options on 'install' (-T) Other packages (sqm-scripts) have openwrt specific makefile sections to avoid GNU options but I suspect this is going to get harder in the future. Add GNU install as a prerequisite and link into $STAGING_DIR/host/etc/bin as per similar GNU utils This resolves an issue building under MacOS which would otherwise use a non-GNU options aware version of 'install' Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
* build: prereq: drop support for Python 3.5Andre Heider2021-03-151-6/+4
| | | | | | | | | | | | | | | | | | | | The final Python 3.5 release was 3.5.10 in September 2020 [0]. This release series is now End-of-Life (EOL). The only LTS distribution that still only ships Python 3.5 is Ubuntu 16.04, which will be EOL in April 2021 [1]. The meson build system bumped their python requirement to 3.6 for the 0.57.0 release. This patch ensures that OpenWrt can update meson while still relying on the host python.

* build/prereq: require make 4.1 or laterPaul Spooren2021-02-151-2/+2
| | | | | | | | | | | | FS#2086 "IS_TTY in the makefile is broken" reports flawed detection of stdout piping to a file. The issue describes how e.g. terminal color codes and up in log files if running make like `make > log.txt`. The proposed solution uses the make variable "MAKE_TERMOUT", which was introduced in make 4.1. All major distributions seem to updated to 4.1 or later, so this ideally dosen't break anything.

* build: prereq: tidy gcc version checksKevin Darbyshire-Bryant2020-03-241-16/+0
| | | | | | | | | | | | | | | | | There is a restriction in the number of parameters(10) that may be passed to the SetupHostCommand macro so continually adding explicit gcc'n' version checks ends up breaking the compiler check for the later versions and oddballs like Darwin as was done in 835d1c68a0 which added gcc10. Drop all the explicitly specified gcc version checks. If a suitable gcc compiler is not found, it may be specified at the dependency checking stage after which that version will be symlinked into the build staging host directory. eg.

* build: simplify gnu-getopt searchKevin Darbyshire-Bryant2020-03-021-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | getopt is the only command where /usr/local/bin is specified explicitly. All other commands are assumed to exist in the PATH in one form or another. Remove this exception and require gnugetopt/getopt to be in the user's PATH. In the case of macos Homebrew, getopt is 'keg only' hence not linked into /usr/local/bin whilst other commands are linked and likely found by virtue of /usr/local/bin being in PATH. Since 2019 Homebrew is very reluctant to install links that have potential to override default OS behaviour, eg: following instructions on our current 'how to build on macos' wiki page: $ brew ln gnu-getopt --force Warning: Refusing to link macOS-provided software: gnu-getopt If you need to have gnu-getopt first in your PATH run: echo 'export PATH="/usr/local/opt/gnu-getopt/bin:$PATH"' >> ~/.zshrc A better option for macos is to link getopt as 'gnugetopt' in /usr/local/bin, thus the build system will find 'gnugetopt' but other applications looking for just 'getopt' will find the original macos binary. Ultimately it makes sense that 'GNU' dependencies are placed in /usr/local/bin and /usr/local/bin is included in the user's PATH. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
* build: add xargs as prerequisiteKevin Darbyshire-Bryant2020-02-291-0/+5
| | | | | | | | | | | | | Build system needs an 'xargs' that supports '-r' which darwin doesn't. Homebrew installs a 'gxargs' with the findutils package so look for 'gxargs' as well as 'xargs' This is a bit of a 'fun' corner case anyway. xargs is only required by the build if 'CONFIG_AUTOREMOVE' is set and after the build system has built 'tools/findutils' we have a fully working xargs for host anyway. Until that time we have to rely on the host's xargs implementation. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>

| | | | | | | | | | | | When bumping buildroot to Python 3, we need to assure, that Python symlink in staging bin directory points to Python >= 3.5 as well. We can't rely completly just on SetupHostCommand as its executed only in cases when the $(STAGING_DIR_HOST)/bin/python doesn't already exist, so we need to remove it before running SetupHostCommand.

* build: switch to Python 3Petr Štetiar2019-07-261-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch switches Python used in buildroot to Python 3 as Python 2.x series is going to be EOL relatively soon[1]. "Being the last of the Python 2.x series, 2.7 will have an extended period of maintenance. Specifically, 2.7 will receive bugfix support until January 1, 2020. After the last release, 2.7 will receive no support." It seems like Python 3 is going to be needed in order to support Meson build system which has gained some traction recently. Build tested on following targets: ath79/generic imx6/generic ipq40xx/generic lantiq/xway layerscape/armv7 (broken) layerscape/armv8_32b (broken) layerscape/armv8_64b (broken) mvebu/cortexa72 ramips/mt7621 ramips/mt7620 sunxi/cortexa7 x86/64 Layerscape targets are unfortunately left broken as their ls-rcw firmware package uses Python 2 and converting it to Python 3 would take more then reasoanble amount of time (I've tried to fix it already) and would be better fixed by someone who can even run test it. Run tested on ath79 (Archer C7 v5), ipq40xx (nbg6617) and x86_64 (QEMU and apu2). 1. https://www.python.org/dev/peps/pep-0373/ Ref: PR#1937 Cc: Yangbo Lu <yangbo.lu@nxp.com> Cc: Mathew McBride <matt@traverse.com.au> Acked-by: Yousong Zhou <yszhou4tech@gmail.com> Signed-off-by: Petr Štetiar <ynezz@true.cz>

| | | | | | | | | | | | | | Busybox time supports the GNU time '-f' syntax used by the build time logging implemented in ff6e62b288c, however the prerequisite check added only works with GNU time installed as `time` or `gtime`. As busybox is a multicall binary, the name of the symlink setup by SetupHostCommand also must be changed from `gtime` to `time` to fix the value of argv[0]. This causes a number of shells (including bash) to use their builtin impelementation of time, so the sole invocation has been changed to use `env time` to use the value found on the $PATH.
