Macでphpenv + php-buildによる環境構築した際にハマった時のメモ（OpenSSLとか）

Mac(10.11, El Capitan)でphpenv+php-buildを使ってPHP環境を整えようとした時に地味にハマったので書き残しておく。

エラー内容

phpenvとphp-buildは既に入っているとして、PHP5.5.27をインストールしようとしたら以下のエラーが出た。

$ phpenv install 5.5.27
[Info]: Loaded extension plugin
[Info]: Loaded apc Plugin.
[Info]: Loaded composer Plugin.

Here are the last 10 lines from the log:

-----------------------------------------
configure: error: Cannot find OpenSSL's <evp.h>
-----------------------------------------

The full Log is available at '/tmp/php-build.5.5.27.20151014105208.log'.
[Warn]: Aborting build.

opensslを入れてみるが"installed"とのこと。

$ brew install openssl
Warning: openssl already installed

多分バージョン変えたほうが良さそう。

opensslのバージョンを変える

$ brew search openssl
homebrew/versions/openssl098				      openssl (installed)
homebrew/versions/openssl101

brew install homebrew/versions/openssl101

openssl101はkeg-onlyとのことなので自分でbrew linkする。

$ brew link --force homebrew/versions/openssl101

PHPインストールしたらまたエラー
