0.26.1 compilation fails at Arch Linux

[anatol]

Trying to build 0.2.6.1 package in a clear build chroot environment at Arch Linux and I get following failure:

Almost definitely a duplicate of #6624
My apologies :(

[bararchy]

@bcardiff @RX14 this is the official build package for Arch Linux, as long as @anatol fails to build Arch users won't get a new release.

[bararchy]

@anatol it seems a fix landed in Master, @Timbus asked if you could retest using master branch (or @Timbus can you offer specific commit point?)

I guess we won't get an official 0.26.1 but at least we might get 0.26.2

[anatol]

I prefer to test a fix commit alone rather than master with many changes. If the fix is going to work then I can release 0.26.1 package to Arch repos.

[Timbus]

I guess the fix commit is here: b697de0

You could possibly apply that as a patch, or check it out at that commit. Would recommend you try building master first and making sure it has been fixed.

[anatol]

Thanks for the pointer.

master branch builds fine, and 0.26.1 release with the patch above also builds fine. I just pushed 0.26.1 package to Arch [testing] repo. @bararchy please verify that it works as expected.

[bararchy]

@anatol The testing package works great for me and the team, we tested on 6 different systems and compiled 9 internal + external projects.

FWIW, I'm seeing the same result:

Unhandled exception: fcntl() failed: Bad file descriptor (Errno)
from ???
from ???
from __crystal_main
...etc...

When I tried to build crystal 0.26.1 on macOS 10.11.6 (El Capitan) using homebrew. I have not tried with the fix. (I had not noticed this PR until about 10 minutes ago...).
