Trying to install Io using homebrew on Mountain Lion (OSX 10.8).

While doing the "make" step of the install of Io itself, the build seems to hang while running the command:

../../_build/binaries/io_static /tmp/homebrew-io-2011.09.12-fHKY/stevedekorte-io-23afbcc/addons/ /tmp/homebrew-io-2011.09.12-fHKY/stevedekorte-io-23afbcc/addons AsyncRequest

The full ps listing is:

I have the same issue trying to build io on 10.8. The build hangs on the AsyncRequest step.

I managed to get io to build on Mountain Lion by first installing gcc:

brew install

and then installing Io using the --use-gcc flag:

brew install --use-gcc io

Same problem here. @HelgeG suggestion worked for me.


Same problem here. @HelgeG suggestion worked as well.

I encountered the same problem, and i did not want to install complete gcc (that too not the latest 4.7)


For me the compilation finished successfully by using llvm


@sarvex Worked for me.. Thank you! :)


Same issue for OS X 10.7, and --use-llvm did work.

io fails_with :clang #14951


I added a fails_with :clang to the formula Homebrew/legacy-homebrew#14951

Using llvm worked perfectly for me, else make was hanging


To clarify, else make with --use-llvm or else make with --use-clang?


Works for me on:

  • OS X 10.8.4
  • XCode 4.6.3



Anyone still having problems?

@zeckalpha zeckalpha io fails_with :clang
make never completes. see: stevedekorte/io#223

I've never put in a fails_with before, so this could be wrong.

Closes #14951.

Now I'm having problems again. I'll look into them tomorrow. If they're related, I'll add them here, but if they are different, I'll open a new issue and I vote we close this one.


It seems to be a different issue. Can we close this one?
