error: --remap-path-prefix must contain '=' between FROM and TO because path contains spaces about rust HOT 7 OPEN

wow, how did you even find that?

Once you mentioned that the error happened while compiling paru (I originally assumed that you were using paru to build something else and hit an error there), I saw the installation instructions mention makepkg. I then went to the pacman repo (which contains makepkg) and searched around a bit until searching for the literal string remap-path-prefix got a match at the linked location.

Are you using RUSTFLAGS to set --remap-path-prefix? If so, you are actually passing two separate args --remap-path-prefix=/home/stereomato/Documents/Software and Development/Repositories/AUR/paru/src=/usr/src/debug/paru as RUSTFLAGS splits on whitespace. Try using CARGO_ENCODED_RUSTFLAGS instead which instead splits the arguments by the 0x1f (ASCII Unit Separator) character.

I'm on arch linux. I don't modify anything, I just try to install paru, but fail with that error. My /etc/makepkg.conf doesn't have that flag on RUSTFLAGS. I wonder what could it be...

The package you are trying to build may be setting RUSTFLAGS to pass `--remap-path-prefix. Which package did you try to build?

Looks like it originates from https://gitlab.archlinux.org/pacman/pacman/-/blob/d55b47e5512808b67bc944feb20c2bcc6c1a4c45/scripts/libmakepkg/buildenv/rust.sh.in#L34, which indeed doesn't handle spaces inside the source path. Disabling the "debug" option may help. I have no clue how to though. Never used makepkg myself.

wow, how did you even find that? 🤔 I guess suggesting the change you mentioned would be a good idea right?
