Trying to reproduce. You don't happen to have a poudriere log?

Created attachment 183432 [details]
poudriere log for rust on FreeBSD 12.0

poudriere log for rust on FreeBSD 12.0

(In reply to Thomas Zander from comment #3)

Log uploaded. How to reproduce:

1) Have FreeBSD 12.0-HEAD/CURRENT
2) compile object base files
3) create poudriere jail:

poudriere jail -c -v 12.0-CURRENT -a amd64 -j f12 -m src=/usr/src

4) Build:

poudriere testport -i -j f12 -o lang/rust

Comment 6 Thomas Zander 2017-06-13 05:38:35 UTC

Build should work again on HEAD. Could you double check whether this problem still exists after r443485 of the ports tree?

updated to r443487. I see rust bumped to 1.18.0. It's build successful on FreeBSD 11.0, but on 12-current still broken.

@dumbbell: Could you take a look at this? I am AFK for a couple of days, unfortunately.

Comment 9 Jean-Sébastien Pédron 2017-06-14 06:43:52 UTC

Hi!

Yes, this is a known issue with Python 2 which is the version required by the Rust build system. Python 2's tarfile module doesn't support sparse file entries in tar archives, but BSD tar tends to use them. And we use tar(1) to recreate the rust-std bootstrap on 12-CURRENT after the ino64 project commit.

The solution is either to use GNU tar which doesn't produce sparse file entries in my tests, or better, pass --format=ustar to BSD tar as suggested by Tim Kientzle.

I need to update my (growing) patch to lang/rust, especially that it conflicts with the 1.18.0 update now :) But I'm still under mentorship so I won't commit it before approval.

Comment 10 Jean-Sébastien Pédron 2017-06-15 06:22:36 UTC

The fix is now part of the following larger patch:

A commit references this bug:

Author: dumbbell

New revision: 443777
URL: https://svnweb.freebsd.org/changeset/ports/443777

Log:
  lang/rust: Enable on FreeBSD/aarch64 + various fixes

  This port now uses an unofficial bootstrap of Rust 1.17.0 and Cargo
  0.18.0 for FreeBSD/aarch64. Here are my notes to create this boostrap:
  https://gist.github.com/dumbbell/b587da50ef014078da9e732a4331ebad

  The port's Makefile was changed to:
      - allow to override the versions and directories of the bootstrap
        archives;
      - patch the bootstrap script and manifest with those
        versions/directories.

  Beside changes to support FreeBSD/aarch64, the port received the
  following fixes:
      - Pass python path to the configure script.
      - Fix and simplify the extraction of rust-std bootstrap by re-using
        existing variables.
      - Make sure tar(1) doesn't produce sparse file entries when it
        recreates the rust-std bootstrap because Python 2's tarfile module
        doesn't support them (PR 219842).

The problem with sparse file entries should be fixed with the commit mentionned above.

If you still see failures, please re-open this report!
