Description D. Marlin 2016-10-12 16:56:32 UTC
Description of problem:

cargo fails to build from source for Fedora EPEL7 on RHELSA-7.2.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.  On a RHELSA-7.2 host:
    mock rebuild cargo-0.13.0-2.el7.2.src.rpm

Actual results:

Error: No Package found for cargo
Error: No Package found for rust

Expected results:

Additional info:

The bootstrap version (cargo-0.12.0-3.el7.1) also fails to build due to dependencies (rust), and it does not include support for AArch64.

In Fedora, it appears that AArch64 was bootstrapped in cargo-0.13.0-2.

Would it be possible to either 1) move to the newer version of cargo (with AArch64 support) in EPEL7, or 2) backport AArch64 support to cargo-0.12.0 for EPEL7?

Comment 1 Josh Stone 2016-10-12 17:40:05 UTC
Once Rust is built, I expect Cargo should be easy.  We can stick to whatever version corresponds to the Rust release we get.  (1.11 + 0.12 or 1.12 + 0.13)
((it's slightly annoying that the minor versions are off by one...))

enable cargo for epel7 aarch64

This cargo.spec patch should hopefully be all that's necessary to bootstrap aarch64.  Assuming you can get rust working, I would appreciate if you could also try this build in your environment.  Thanks!

Comment 3 D. Marlin 2016-10-14 19:35:51 UTC
Using the patched version of rust in the buildroot, and above patch to cargo, I get the following error:

Comment 4 Josh Stone 2016-10-14 20:35:04 UTC
Ah, right, I changed how that was done in the next release.  For now, to keep this minimal, it probably just needs another small addition:

Comment 5 D. Marlin 2016-10-14 21:58:35 UTC
With that additional change, cargo-0.12.0-3.el7.2 successfully builds.
