rust: Failed to destroot rust

[Dave-Allured (Dave Allured)]

I am attempting a private build of Macports in my home directory, without root privileges. Starting from a clean build of Macports 2.5.3, port -v install rust completes 44 ports, ending with llvm-6.0 @6.0.1_0. Next, rust @1.27.2 builds successfully, then fails on a copy in install/destroot with "no such file or directory". In the copy arguments, the source directory exists, but the destination directory does not exist. See the specific paths in the code box below.

Port clean followed by a second port install failed in the same way.

MacOS version 10.13.6, High Sierra. Xcode version 9.4.

Here are brief excerpts near the end of console output. Also attached is the full main.log from the rust work directory.

running: "sh" "/Volumes/User/dallured/macports/var/macports/build/" <snip>
install: creating uninstall script at <snip>

    Rust is ready to roll.

main.log from rust work directory

[Dave-Allured (Dave Allured)]

rust@1.29.0 fails in the same way, "Failed to destroot rust" due to missing directory. Attaching main.log from "port install" of rust@1.29.0.

main.log from "port install" of rust@1.29.0

[Dave-Allured (Dave Allured)]

A workaround is to manually create the single missing directory before running "port install rust". This caused my private install of rust@1.29.0 to complete successfully.

[Dave-Allured (Dave Allured)]

If I am not mistaken, there are two mkdir commands missing from the rust@1.29.0 portfile. Maintainer, if you agree, please add these commands in Portfile, just in front of the two matching "file copy" commands.

file mkdir ${destroot}${prefix}/lib/rustlib/${rust_platform}/analysis
...
file mkdir ${destroot}-${arch}${prefix}/lib/rustlib/${rust_platform}/analysis

I think I forgot to CC port maintainer. @g5pw, doing it now.

[Dave-Allured (Dave Allured)]

Rust @1.29.1 fails in the same way on macports 2.5.4.

[Dave-Allured (Dave Allured)]

This issue resolved itself by magic several months ago, around the time when Macports base went from 2.5.4 to 2.6.2.

I do not know what changed. I can build rust now without hacking. It is okay to close this ticket.

Ok, thanks for reporting it! Closing.
