* include/prereq.mk: add RequireCHeader helperChristian Marangi2023-01-091-0/+12
| | | | | | | | | | | | 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 whichAnsuel Smith2022-01-171-2/+2
| | | | | | | | | | | | | | 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. Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com>
* Revert "build: replace which with Bash command built-in"Clemens Fruhwirth2021-03-031-2/+2
| | | | | | | | | | | 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-inPetr Štetiar2021-01-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | `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 <ynezz@true.cz>
* build: cleanup possibly dangling Python 2 host symlinkPetr Štetiar2019-07-261-0/+12
| | | | | | | | | | | | 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 argumentsJo-Philipp Wich2018-04-051-1/+2
| | | | | | | | | | | | | 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 <jo@mein.io>
