You just don't have zlib.
thomasjo commentedon Oct 9, 2015
@nikolay Ensure that your Xcode (including Command Line Tools) is up to date. Latest version is v7.0.1.
nikolay commentedon Oct 9, 2015
I do have both, of course. zlib is installed via Homebrew and I have Xcode 7.1 beta and I haven't updated it since it worked last time, i.e. it's not the beta version of Xcode.
thomasjo commentedon Oct 9, 2015
Well, something is wrong with your environment, because it works perfectly fine on my (clean) OS X 10.11 (15A284) system with Xcode 7.0.1 (7A1001).

Same issue for me too, 3.4.x build correctly but not 3.5, Xcode is up to date
nikolay commentedon Oct 9, 2015
Well, I'm not sure what's wrong with my environment if 3.4.3 builds and 3.5.0 doesn't.
yyuu commentedon Oct 9, 2015
Hmm, sounds interesting.
For more investigation, could you create a gist from output of 'pyenv install -v 3.5'?

@nikolay I had the same issue, and was able to fix by updating command line tools on OSX. Just run
xcode-select --installOnce, that's finished, you should be able to install 3.5.0
nikolay commentedon Oct 20, 2015
@swarajban I've done this, of course. It's not that. It does not work. I tried once more. Same exact issue. 3.4.3 works, 3.5.0 fails miserably.
yyuu commentedon Oct 21, 2015
Umm. I've finished upgrading to El Capitan, but I couldn't reproduce the build failure of 3.5.0 on it....
VirtualWolf commentedon Oct 27, 2015
I was having the same problem. The fix for me, despite already having Xcode installed and up-to-date (7.1), was running
xcode-select --installand installing the command line tools.qtfkwk commentedon Oct 28, 2015
I also had this issue but it's fixed now via
xcode-select --install... I have XCode 7.1... Homebrew, etc, are working fine otherwise... no complaints about xcode-select, libraries missing, etc before trying to install Python 3.5.0. I will try to remember to runxcode-select --installfrom now on after upgrading XCode. Here's a copy of my session:yyuu commentedon Nov 13, 2015
