include/prereq.mk: add RequireCHeader helper

2023-01-09T20:25:06Z

Add RequireCHeader helper that will try to compile a fake c program with the requested header included. This is useful to check if a specific header is present in the system without checking for the specific path. This is a generilized version of the current ncurses test.

treewide: drop use of which

2022-01-17T08:14:26Z

Ubuntu started to flag which as deprecated and it seems which is not really standard and may vary across Distro. Drop the use of which and use the standard 'command -v' for this simple task. Which is still present in the prereq if some package/script still use which. A utility script called command_all.sh is implemented that will just mimic the output of which -a.

Revert "build: replace which with Bash command built-in"

2021-03-03T21:51:39Z

This reverts commit c7aec47e5e3a3ff7b5fdaa11cd1e62cae6746acb. The original commit replaces 'which' with 'command'. Sadly most of them are not equivalent and for 'which -a', there is no easy replacements that would not reimplement PATH parsing logic. Hence revert. Keeping a dependency on which is absolutely fine.

build: replace which with Bash command built-in

2021-01-04T18:32:25Z

`which` utility is not shipped by default for example on recent Arch Linux and then any steps relying on its presence fails, like for example following Python3 prereq build check: $ python3 --version Python 3.9.1 $ make /bin/sh: line 1: which: command not found /bin/sh: line 1: which: command not found /bin/sh: line 1: which: command not found ... Checking 'python3'... failed. ... Fix this by switching to Bash builtin `command` which should provide same functionality. Fixes: FS#3525 Signed-off-by: Petr Štetiar

build: cleanup possibly dangling Python 2 host symlink

2019-07-26T06:09:16Z

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.

include: extend SetupHostCommand macro to accept more arguments

2018-04-05T11:58:15Z

Commit d6d3db0543 added more gcc version probes, exceeding the argument limit of the SetupHostCommand macro, leading to failing GCC/LLVM tests on OS X. Extend the handled number of arguments to restore proper functionality. Fixes FS#1470 Fixes d6d3db0543 ("build: Improve GCC version detection") Signed-off-by: Jo-Philipp Wich

build: do not overwrite already existing host commands

2015-09-16T12:38:16Z

This prevents a later prereq check from overwriting the installed tar binary. Signed-off-by: Felix Fietkau SVN-Revision: 46982
