[Solved]makepkg can't find bash

i'm trying to build the esp-open-sdk but it says my bash is outdated:

checking for bash >= 3.1... no
configure: error: could not find bash >= 3.1
make[1]: *** [../Makefile:143: _ct-ng] Error 1
make[1]: Leaving directory '/home/badbob/esp8266/esp-open-sdk-git/src/esp-open-sdk/crosstool-NG'
make: *** [Makefile:139: crosstool-NG/ct-ng] Error 2
==> ERROR: A failure occurred in build().
    Aborting...

obviously i have bash and is newer that 3.1:

100% 12:44 ~ > which bash
/usr/bin/bash
100% 12:45 ~ > bash --version
GNU bash, version 5.0.0(1)-release (x86_64-pc-linux-gnu)

i've done this before on this same computer running arch without this problem... i'm stumped

Welcome to the arch linux forums badbob.  What is the contents of config.log probably in /home/badbob/esp8266/esp-open-sdk-git/src/esp-open-sdk/crosstool-NG ?

Re: [Solved]makepkg can't find bash

thanks for having me.  can't remeber the last time i posted on the internet; i can always find someone else asking the same question i have.

anyway it's working now . i simply added the 5 to this line in configure.ac:

[[_BASH_ver=$($ac_path__BASH --version 2>&1 \
                     |$EGREP '^GNU bash, version (3\.[1-9]|4)')

thanks a bunch!

Please consider leaving a message on the AUR package page about the issue and reporting it upstream at https://github.com/pfalcon/esp-open-sdk/issues

Re: [Solved]makepkg can't find bash

The crosstool-ng project's configure.ac will try to search for bash "at least 3.1" using the following rule:

bash --version | egrep '^GNU bash, version (3\.[1-9]|4)'

This inaccurate heuristic match misses bash 5. It was recently (14 days ago) amended to match "5" as well: https://github.com/jcmvbkbc/crosstool-NG/pull/56

The package you are trying to build, includes a submodule for crosstool-ng that is from 2017.

I'll leave you to draw your own conclusions on where the problem lies, and also about how reliable this package is.

I'm nevertheless baffled why crosstool-ng does not use pkg-config instead of grep. Or even do proper arithmetic:

BVER="$(bash -c 'echo "${BASH_VERSION%%.*}"')"
[ "${BVER%%.*" -gt 3 ]
