Compile PHP 5.5.14 on upgrade from MAMP Pro 5.5.10 php -i /configure

This will require the use of Brew.

sudo brew install gettext

//create symbolic link to lib location, needed for php compilation

//this will also fix any linking errors that might occur related to libintl.h 

ln -s /usr/local/Cellar/gettext/0.18.3.2/lib/libintl.* /usr/local/lib/

sudo brew install t1lib

The php that comes with MAMP Pro is compiled with the following ./configure command. To verify that this is the case you can issue php -i command in the location of your php executable, usually in /Applications/MAMP/bin/php/phpxxxxxx/bin/.

./configure  --with-mysql=/Applications/MAMP/Library --with-gd --with-jpeg-dir=/Applications/MAMP/Library --with-png-dir=/Applications/MAMP/Library --with-zlib --with-zlib-dir=/Applications/MAMP/Library --with-freetype-dir=/Applications/MAMP/Library  --enable-ftp --enable-gd-native-ttf --with-bz2=/usr --with-ldap --with-mysqli=/Applications/MAMP/Library/bin/mysql_config --with-t1lib=/Applications/MAMP/Library --enable-mbstring=all --with-curl=/Applications/MAMP/Library --enable-sockets --enable-bcmath --with-imap=shared,/Applications/MAMP/Library/lib/imap-2007f --enable-soap --with-kerberos --enable-calendar --with-pgsql=shared,/Applications/MAMP/Library/pg --enable-exif --with-libxml-dir=/Applications/MAMP/Library --with-gettext=shared,/Applications/MAMP/Library --with-xsl=/Applications/MAMP/Library --with-pdo-mysql=shared,/Applications/MAMP/Library --with-pdo-pgsql=shared,/Applications/MAMP/Library/pg --with-mcrypt=shared,/Applications/MAMP/Library --with-openssl --enable-zip --with-iconv=/Applications/MAMP/Library --enable-opcache --enable-cgi --enable-intl --with-icu-dir=/Applications/MAMP/Library --with-tidy=shared
