Cargo build log file

[ryandesign (Ryan Carsten Schmidt)]

It is a bug that cargo is trying to do any fetching at all outside of the fetch phase. See #56195. Fixing that bug is all we need to do to solve this problem.

[raimue (Rainer Müller)]

No, this is a different problem. Yes, #56195 will solve it for the cargo port, but this is still a bug in cargo itself. Remember cargo can be used for development and not only for building ports. That this bug triggers in a port build is just a coincidence.

cargo includes a bundled copy of libgit2. Therefore this problem could be the same as in this upstream issue: ​https://github.com/libgit2/libgit2/issues/4350

I recommend to report the problem to cargo upstream.

Same issue on 10.12.6:

:info:build error: failed to load source for a dependency on `atty`

Not sure if this helps, but it helped me:

1. backed up the list of all ports
2. port -f uninstall installed
3. installedmacports 2.4.3 freshly from source
4. re-installed all previously installed ports

-> cargo built on two machines now

[cgilles (HumanDynamo)]

Confirmed. To re-init whole Port installation and to rebuild all from scratch fix the problem. Now Cargo build when installing ffmpeg work as expected :

So, this file can be closed now...

Replying to raimue:

That libgit2 issue has been closed presumed fixed, though without mentioning what the fix was or in what version of libgit2 the fix was released. Given the above comments that the problem no longer appears in MacPorts cargo, I will presume that this is fixed for us too.
