Build error on macOS 10.12.6

[killkrt]

Hi,

Compiling with rust 1.25.0 (on macOS 10.12.6) I got this error:

error: unexpected close delimiter: `]`
    --> /Users/killkrt/Developer/coreaudio-sys/target/debug/build/coreaudio-sys-d982877313451e0c/out/coreaudio.rs:2164:33
     |

     |                                 ^

What does xcode-select -p say?

[killkrt]

Here it is the output: /Library/Developer/CommandLineTools

[Rhuagh]

That's one weird location.

[Rhuagh]

@killkrt Could you try out #11 ?

[killkrt]

Sadly it hasn't solved my issue. Now I have this error:

hmm, and you cloned my branch? what does defaults read loginwindow SystemVersionStampAsString give you ?

[killkrt]

Sorry, my bad, I was on the master branch, now I switched to fix/older-versions and I get the same error I got in the first post:

error: unexpected close delimiter: `]`
    --> /Users/killkrt/Developer/coreaudio-sys/target/debug/build/coreaudio-sys-f8869d8ef70218e2/out/coreaudio.rs:2164:33

error: aborting due to previous error

error: Could not compile `coreaudio-sys`.

To learn more, run the command again with --verbose.
Kills-iMac:coreaudio-sys killkrt$ git branch

[killkrt]

Ups, sorry, I forgot to post the output of command that you asked me:

Kills-iMac:coreaudio-sys killkrt$ defaults read loginwindow SystemVersionStampAsString
10.12.6

[Rhuagh]

That looks like bindgen producing broken code.

What xcode version are you running?

[Rhuagh]

xcodebuild -version

[killkrt]

Umh, that's weird:

Kills-iMac:~ killkrt$ xcodebuild -version
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

I fixed it using:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

So now it is returning:

Xcode 9.2
Build version 9C40b

Then I restarted the Terminal application made a cargo clean && cargo build, but I'm still experiencing the same problem (unexpected close delimeter...)

[Rhuagh]

Super weird, I don't know what else to consider here. I can't reproduce it using Xcode 9.2 on Travis either.

[Rhuagh]

Try reinstalling Xcode maybe?

[killkrt]

I found the issue! It was rustfmt, updating it made the trick! You can close the issue!

Thank you for the support!

[Rhuagh]

AH, np! Good that you found it! :)
