In the cargo.eclass in cargo_src_install, line 181 there is [ -d "${S}/man" ] && doman "${S}/man" || return 0 However, invoking doman on a directory returns an error, and the ebuild fails. Instead, it should be [ -d "${S}/man" ] && doman "${S}/man/*" || return 0 An example where this is an issue is https://github.com/orhun/kmon Note that this fix does not cover the edge case of directories within the man directory - why anyone would do this is beyond me, but I'm not to judge Regards, Jannik
Indeed it's wrong. I currently use a workaround and move man directoy and call doman explicitly later in install phase, but it should be fixed.
Would it be possible to entirely remove this? Man pages are generally not handled by Cargo, so cargo.eclass trying to install them is rather surprising.
yes, it needs to go. it's a historical thing that assumes that such directory structure is standard, which turned out not quite the fact. I'll all in favor for removing it, but first I'll need to find all ebuilds that actually rely on it, and replace with proper doman calls. Can't just make a eclass change that affects results of installation. if you happen to know such ebuilds - let me know =) Otherwise I'll have to emerge all cargo.eclass's cargo_src_install() consumers and check file lists.

I only have a few Rust-based packages installed, but maybe this fish shell script helps: ❯ for inherit in /var/db/pkg/*/*/INHERITED grep -q cargo $inherit || continue set -l package (string replace /var/db/pkg/ '' (dirname $inherit)) set -l contents (dirname $inherit)/CONTENTS grep -q '^dir /usr/share/man$' $contents && echo $package end app-benchmarks/hyperfine-1.11.0 app-misc/skim-0.9.3 dev-vcs/mercurial-5.7 gui-libs/greetd-0.7.0 sys-apps/bat-0.17.1-r1 sys-apps/exa-0.9.0-r1 sys-apps/fd-8.2.1 sys-apps/ripgrep-12.1.1 sys-apps/zram-generator-0.3.2 x11-terms/alacritty-0.7.2 I also briefly checked whether https://www.portagefilelist.de could be of help, but they index only files, not directories, and the paths to those files are not searchable.
