Mac version issue

[terrylai]

Hello,

I have successfully built Win version 32 & 64 bits of bitcoin v0.13.0.

Then I tried to build for Mac OS but there exists error when processing which is shown in the following:

/gbuild:21:in `system!': failed to run on-target setarch x86_64 bash -x < var/build-script > var/build.log 2>&1 (RuntimeError)

from ./bin/gbuild:149:in `build_one_configuration'
from ./bin/gbuild:285:in `block (2 levels) in <main>'
from ./bin/gbuild:280:in `each'
from ./bin/gbuild:280:in `block in <main>'
from ./bin/gbuild:278:in `each'
from ./bin/gbuild:278:in `<main>

Could someone help me how to solve it?

Thanks!

You need to check var/build.log (in your gitian-builder directory) to see what the error is.

I got this same error building Linux (with LXC and cached packages). I messed around with it (re-created apt-cacher-ng cache, upgraded it to a newer version from Debian testing, etc.) and think I got past this particular error that way.

Upgrading system, may take a while
./bin/gbuild:21:in `system!': failed to run on-target -u root bash < target-bin/upgrade-system.sh > var/install.log 2>&1 (RuntimeError)
        from ./bin/gbuild:105:in `build_one_configuration'
        from ./bin/gbuild:285:in `block (2 levels) in <main>'
        from ./bin/gbuild:280:in `each'
        from ./bin/gbuild:280:in `block in <main>'
        from ./bin/gbuild:278:in `each'
        from ./bin/gbuild:278:in `<main>'

Install.log didn't contain any additional information, by the way.

But then I ran into the same error that you pasted, but in copy-from-target.
I tried many things so I'm not sure what it was, but I think it's related to the way tar commands work.
I looked at closed bugs here and there was a bug about tar a while ago.
I injected some logging into the scripts (no idea whether I did it right) and got this:

tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

I don't know if this makes any sense and it's in another area, but it may be related.
Originally I used Debian 8.6 with testing repos added separately but I nuked the whole thing after having spent 8 hours trying to make it work, so I can't provide additional details.
