Bug 645466 – dev-lang/rust-1.23 mv: cannot stat '/tmp/portage/dev-lang/rust-1.23.0/image//usr/share/doc/rust/*': No such file or directory

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Oleg 2018-01-23 18:06:23 UTC]

When I builds =dev-lang/rust-1.23.0 with "doc" enabled I gets error:

< Rustc { stage: 2, target: "x86_64-unknown-linux-gnu", host: "x86_64-unknown-linux-gnu" }
Build completed successfully in 0:04:28
mv: cannot stat '/tmp/portage/dev-lang/rust-1.23.0/image//usr/share/doc/rust/*': No such file or directory

As I see the documentation is already placed in ${D}/usr/share/doc/rust-1.23.0/ so it shouldn't be moved. I deleted lines from ebuild and dev-lang/rust-1.23.0 installed correctly.

Thanks for the report!

What lines did you remove, exactly? If you can provide a unified diff, that would be helpful.

I removed next lines from src_install:

        if use doc ; then
                dodir "/usr/share/doc/rust-${PV}/"
                mv "${D}/usr/share/doc/rust"/* "${D}/usr/share/doc/rust-${PV}/" || die
                rmdir "${D}/usr/share/doc/rust/" || die
        fi

I have the same issue.

usr/lib64/rustlib/install.log written by Rust build system

[Comment 6 Marien Zwart 2018-01-25 11:12:59 UTC]

Same here :)

After the build has failed, image/usr/share/doc/rust-1.23.0 contains a few README/LICENSE/COPYRIGHT files and an "html" directory containing 123M of documentation. So it looks like Rust's build system already put the documentation where we want it, and comment #2 has it right (that part of src_install breaks everyone with USE=doc set).

I suspect this happens because src_configure adds the following lines to config.toml:

		docs = $(toml_usex doc)

		docdir = "share/doc/${P}"

...and those are all we need to install documentation to the correct directory and make USE=doc work.

Also note the docdir looks new to this ebuild (rust-1.19.0.ebuild set a different one).

I confirm that removing these lines resolves the problem

I've removed the offending lines from rust-1.23.0-r1, thanks!
