It looks like a change to the latest GCC. I see this patch to Ruby trunk has addressed the issue?

The last 10 log lines are showing a warning, but not the errors.

Could you include the build errors in /var/folders/5y/csxbdjv156n4fl25975s1x4w0000gn/T/ruby-build.20160921163419.48224.log ?

Puzzling:

checking for clockid_t... no
checking for convertible type of clockid_t... INT

But clockid_t is clearly checked for in time.h:

AC_CHECK_TYPES([clockid_t], [], [], [@%:@ifdef HAVE_TIME_H
@%:@ include <time.h>
@%:@endif
@%:@ifdef HAVE_SYS_TIME_H
@%:@ include <sys/time.h>
@%:@endif])

And it's available in /usr/include/time.h:

typedef enum {
…
} clockid_t;

What the heck?

[jeremy]

Hm, I see the same config locally, but my compile goes through fine too.

[tylerjohnst]

Not seeing that typedef in /usr/include/time.h on a clean install of Sierra. For reference: https://gist.github.com/tylerjohnst/f45a53a9691301aafcdf6cfdb18a78b8

Fmm, I couldn't reproduce this with macOS Sierra and Xcode 8.0 release version.

[tylerjohnst]

I've figured out the issue:

Theres a bug with the App Store where Apple is pushing out updates to the Xcode7 version of the CLI tools that can update even if the Xcode8 version of the tooling is installed. This was causing the strange behavior in the header files.

Solution:
rm -rf /Library/Developer/CommandLineTools and reinstall the command line tools. Ruby builds correctly now.

[tylerjohnst]

For reference, this is what the App Store update looks like. It will go away after a few "refreshes" of the App Store. Hope this issue helps someone else out.

[jeremy]

Whew! Thanks for tracking that down @tylerjohnst.

[Zeldalink]

thanks 👍

Basically, it just didn't have write permission , use sudo rbenv install 2.3.1 and works fine

[igolden]

If it helps anyone, I fixed the error by running rm -rf /Library/Developer/CommandLineTools && xcode-select --install. That installs most recent Command Line Tools (8+) if you're running Sierra.

Great @tylerjohnst, you save my day!
