Can't compile on El Capitan

[alanorth]

Using current master as of 2015-09-27 on El Capitan 10.11.1 beta. Assuming latest pyenv should bootstrap its own OpenSSL and readline:

$ pyenv install 3.4.3

I'm using pkgsrc instead of homebrew, so I tried to add relevant flags:

$ CFLAGS="-I$(xcrun --show-sdk-path)/usr/include -I/opt/pkg/include" LDFLAGS="-L/opt/pkg/lib" pyenv install 3.4.3

Ok, I just tried in an environment without pkgsrc paths (/opt/pkg) and this worked:

$ pyenv install 3.4.3
Installing openssl-1.0.1p...
Installed openssl-1.0.1p to /Users/aorth/.pyenv/versions/3.4.3

Installing readline-6.3...
Installed readline-6.3 to /Users/aorth/.pyenv/versions/3.4.3

Installing Python-3.4.3...
Installed Python-3.4.3 to /Users/aorth/.pyenv/versions/3.4.3

I guess this is a problem with my environment mixing libs, headers, PATHs, etc. I'll close this now.

[case]

Fwiw, this did the trick for me:

CFLAGS="-I$(brew --prefix openssl)/include -I$(xcrun --show-sdk-path)/usr/include" \
LDFLAGS="-L$(brew --prefix openssl)/lib" \
pyenv install -v 3.4.3

The above solution did not work in my case (an upgrade of a relatively fresh Yosemite to El Capitan). This worked for me:

xcode-select --install

brew install openssl
brew install readline
brew install pyenv --HEAD

export PYENV_ROOT=/usr/local/var/pyenv
pyenv install 2.7.10
pyenv install 3.4.3

[intentionally-left-nil]

FWIW, these are the settings I had to use (specifically note that including the --show-sdk-path did NOT work for me)

brew install readline
brew install openssl
brew install pyenv
brew install sqlite3
export CFLAGS="-I$(brew --prefix openssl)/include"
export LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix sqlite3)/lib"
export CPPFLAGS="-I$(brew --prefix sqlite3)/include"
pyenv install 2.7.10

$ xcode-select --install did it for me

oh, and

$ brew list | egrep '(openssl|readline)'
openssl
readline

[living4life]

this works for me:

$ brew link --force openssl
$ xcode-select --install 
$ pyenv install 3.3.5
$ pyenv global 3.3.5

[toearth]

This works for me:
brew install openssl
brew install pyenv
brew install sqlite3
export CFLAGS="-I$(brew --prefix openssl)/include"
export LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix sqlite3)/lib"
export CPPFLAGS="-I$(brew --prefix sqlite3)/include"
pyenv install 3.5.1

If the version you need is missing, try upgrading pyenv:

brew update && brew upgrade pyenv

A few things to look at:

Besides pyenv I also could not install ruby versions via rbenv. At this point I started looking at the system. I'd recently upgraded and used the migration assistant to move to a new machine.

1. go to Applications and run Xcode. I had additional packages install
2. run brew doctor. if any files in /usr/local/include show up you have 2 options. Either rename the directory to something else like include_old or remove the offending entries. I chose the first.

sudo mv /usr/local/include /usr/local/include_old
sudo mkdir /usr/local/include
sudo chown $YOU_USERNAME:admin /usr/local/include

afterward, I was able to install ruby and python versions
