So the question then is, what is this resolving to? checking for bash... /gnu/store/whkq7f2d702hqnrdd2cqskqxdx267283-profile/bin/bash
It needs to be bash >= 4.4.0, and we have a check which is supposed to enforce this: https://git.archlinux.org/pacman.git/tree/configure.ac?h=v5.2.1#n201 What version is your bash program, and why might it be refusing to recognize this bash syntax?
The bash version is 5.0.7 $ /gnu/store/whkq7f2d702hqnrdd2cqskqxdx267283-profile/bin/bash --version GNU bash, version 5.0.7(1)-release (x86_64-unknown-linux-gnu)
Why is this happening so often:
/gnu/store/whkq7f2d702hqnrdd2cqskqxdx267283-profile/include/stdlib.h:257:4: warning: ISO C does not support the ‘_Float64x’ type [-Wpedantic]
--pedantic is a GCC flag which causes every non-standard C to raise an error, even though it may be an available extension in GCC. And, -Wpedantic will warn about these deviations from the standard. Despite the errors and warnings, it appears that I have a working pacman. Thanks a lot, Eli. $ pacman --version .--. Pacman v5.2.1 - libalpm v12.0.1 / _.-' .-. .-. .-.
