This looks like a packaging issue with libgit2, have you reported this to FreeBSD?

This looks like a packaging issue with libgit2

FreeBSD libgit2 package didn't change since 2019-03-31 while old Nightly snapshots with current libgit2 work fine:

• 20190811 affected
• 20190806 affected
• 20190723 works fine
• 20190711 works fine

Bisecting cargo led to rust-lang/cargo#7018 but I'm still puzzled given FreeBSD libgit2 package is at 0.28.1.

[jbeich]

Updating libgit2 to 0.28.2 doesn't help.

I have the same problem with upcoming stable 1.38.0 on OpenBSD, when built with libgit2-0.28.1

[semarie]

@jbeich I took your patch for OpenBSD. Thanks for have restored the compatibility

This has hit Alpine Linux too.

Can this issue be closed after meta-rust/meta-rust#279 ?
