datePosted on 12:46, February 25th, 2011 by Many Ayromlou


Yep it’s that time of the year again. Mark February 26 & 27 in your calendars…..PODCAMP TORONTO 2011 IS COMING TO TOWN. PodCamp Toronto 2011 is a FREE “unconference” bringing together professionals and hobbyists from Toronto and the surrounding area to explore the cutting edge of new and social media. If you are an online content creator – hobbyist and professionals – who are building communities online in a variety of ways, then PodCamp Toronto 2011 is for you. Share ideas, discuss theories and learn lessons from an audience of experts.

We’ll be at Ryerson University’s flagship centre for studies in converging communications and interactive media — Rogers Communications Centre. In operation for almost twenty years, the Rogers Communications Centre has grown to become Canada’s premier facility for education in digital media communications.

The Rogers Communications Centre is about design and research in a community employing both current and advancing communications technology. These five themes have placed the Rogers Communications Centre among the best educational communication and design facilities internationally.

Just steps away from Yonge Street and the heart of Toronto, the Centre is located at the core of Canada’s electronic media and digital communications culture.

So have you reserved your seat yet? Why the hell not? :-).

Adding mcrypt support to builtin php5 on OSX Leopard….

datePosted on 17:51, February 4th, 2011 by Many Ayromlou

I got a request to add mcrypt support to our Leopard server today and here is a brief step-by-step installation instruction. This works well under the current 10.5.8 server installation. It should also work for 10.6 (snow leopard), but I have not tried it. Before you start here are the requirements:

  • Backup your system
  • Install (and update) the latest XCode (I’ve got version 3)
  • Install X11 client stuff from your server install DVD
  • install X11 SDK stuff from your server install DVD
  • Ensure you have server 10.5.8 (latest update as of Feb.04.2011)
  • Make sure you have not tried to install mcrypt using another method. We need a “virgin” 10.5.8 install (as far as homebrew/local installs)
  • BACKUP

Please note that this will add mcrypt support to php. This is NOT the same as compiling mcrypt.

Okay, so now that we have all the requirements, you need to get a command line window opened and get a root shell (sudo -i). The rest of this document assumes you’re typing the commands in a root shell.

There is one dependency that we need to clear before we actually get down and dirty and that is libmcrypt. Follow the instructions below to get this installed:

mkdir /SourceCache
cd /SourceCache
curl http://sourceforge.net/projects/mcrypt/files/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.bz2/download -o libmcrypt-2.5.8.tar.bz2 -L

This is the latest version as of this writing (Feb.04.2011).

NOTE: If you’re compiling on a G5 machine you’ll need to tell the compiler that you want to build/configure for a ppc64 target so instead of the below configure command you need to use this:

MACOSX_DEPLOYMENT_TARGET=10.5 CFLAGS=" -arch ppc64 -g -Os -pipe -no-cpp-precomp" CCFLAGS=" -arch ppc64 -g -Os -pipe" CXXFLAGS="-arch ppc64 -g -Os -pipe" LDFLAGS="-arch ppc64 -bind_at_load" ./configure --enable-shared
tar -xjvf libmcrypt-2.5.8.tar.bz2
cd libmcrypt-2.5.8/
./configure
make
make -n install

The last command will simulate the installation process. Make sure the stuff is getting installed in /usr/local/lib

make install

At this point you should have a working installation of libmcrypt. This next command prints out the current version of your php engine. In my case under 10.5.8 it’s php 5.2.14.

server:libmcrypt-2.5.8 root# php -v
PHP 5.2.14 (cli) (built: Oct  6 2010 16:57:10)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies

Grab the appropriate php-5.2.XX.tar.bz2 file from php.net. I just grabbed the stock PHP 5.2.14, since I wanted a perfect match between my php engine and the extension. I transferred the file using sftp to the /SourceCache folder on the server.

NOTE: If you’re compiling on a G5 machine you’ll need to tell the compiler that you want to build/configure for a ppc64 target so instead of the below configure command you need to use this:

MACOSX_DEPLOYMENT_TARGET=10.5 CFLAGS=" -arch ppc64 -g -Os -pipe -no-cpp-precomp" CCFLAGS=" -arch ppc64 -g -Os -pipe" CXXFLAGS="-arch ppc64  -g -Os -pipe" LDFLAGS=" -arch ppc64  -bind_at_load" ./configure --with-php-config=/Developer/SDKs/MacOSX10.5.sdk/usr/bin/php-config
cd /SourceCache
tar xjvf php-5.2.14.tar.bz2
cd /SourceCache/php-5.2.14/ext/mcrypt
phpize
./configure --with-php-config=/Developer/SDKs/MacOSX10.5.sdk/usr/bin/php-config
make
make test
make -n install

The last command will simulate the installation process. Make sure the stuff is getting installed in /usr/lib/php/extensions/no-debug-non-zts-20060613

make install

Now we need to modify our php.ini file and tell the php5 engine of the availability of this new module. To do this you need to copy php.ini.default to php.ini (in /etc directory). For details of why have a look at this article.

cd /etc
cp php.ini.default php.ini

Edit the newly created/copied php.ini using your favourite editor. Add the following line to the appropriate location (read the comments in the file to find the location):

extension=mcrypt.so

Still in the same file find the variable “extension_dir” and change it’s value to “/usr/lib/php/extensions/no-debug-non-zts-20060613” path instead of “./”. Save the php.ini and use the following command to see if mcrypt extensions are available:

server:etc root# php -i |grep mcrypt
mcrypt
mcrypt support => enabled
mcrypt.algorithms_dir => no value => no value
mcrypt.modes_dir => no value => no value

Done. Restart Apache service from the server manager (just for the sake of completeness).

Adding GD support to builtin php5 on OSX Leopard….

datePosted on 15:17, February 4th, 2011 by Many Ayromlou

I got a request to add GD support to our Leopard server today and here is a brief step-by-step installation instruction. This works well under the current 10.5.8 server installation. It should also work for 10.6 (snow leopard), but I have not tried it. Before you start here are the requirements:

  • Make sure you have not tried to install GD using another method. We need a “virgin” 10.5.8 install (as far as homebrew/local installs)
  • BACKUP

Please note that this will add GD support to php. This is NOT the same as compiling the GD graphics library (libgd).

Okay, so now that we have all the requirements, you need to get a command line window opened and get a root shell (sudo -i). The rest of this document assumes you’re typing the commands in a root shell.

There is one dependency that we need to clear before we actually get down and dirty and that is libjpeg (known as jpegsrc). Follow the instructions below to get this installed:

mkdir /SourceCache
cd /SourceCache
curl -O http://www.ijg.org/files/jpegsrc.v8c.tar.gz

This is the latest version as of this writing (Feb.04.2011).

NOTE: If you’re compiling on a G5 machine you’ll need to tell the compiler that you want to build/configure for a ppc64 target so instead of the below configure command you need to use this:

MACOSX_DEPLOYMENT_TARGET=10.5 CFLAGS=" -arch ppc64 -g -Os -pipe -no-cpp-precomp" CCFLAGS=" -arch ppc64 -g -Os -pipe" CXXFLAGS="-arch ppc64 -g -Os -pipe" LDFLAGS="-arch ppc64 -bind_at_load" ./configure --enable-shared
tar -zxvlf jpegsrc.v8c.tar.gz
cd jpeg-8c/
./configure
make
make test
make -n install

The last command will simulate the installation process. Make sure the stuff is getting installed in /usr/local/lib

make install

At this point you should have a working installation of libjpeg. Now we double check our php version.

server:jpeg-8c root# php -v
PHP 5.2.14 (cli) (built: Oct  6 2010 16:57:10)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies

Notice in the output that I have php 5.2.14 installed on the machine (again the latest update as of Feb.04.2011). Apple does not provide source code for this exact version of PHP. On top of that The numbering scheme that they use is weird. On my machine it is “apache_mod_php-44.6”, you can find yours using the following:

server:jpeg-8c root# php -i |more
phpinfo()
PHP Version => 5.2.14

The thing you’re looking for (“apache_mod_php-44.6”) is under Configure Command. If you go to the following URL (http://www.opensource.apple.com/source/apache_mod_php/) in your browser (safari, firefox) you’ll soon discover these weird directory names with numbers that don’t match the php versions. Again, as of this writing (Feb.04.2011), I can’t find apache_mod_php-44.6 folder in the listing so I grabbed the nearest numbers apache_mod_php-44.2 which is php 5.2.8…….close enough. It seems to work. Follow the steps below to get the file and compile the GD portion of it. Remember we’re not recompiling the entire php, just the GD plugin portion.

UPDATE: You CAN install the exact version of your PHP’s GD extension. Instead of grabbing the file from Apple, figure out the version of your PHP using “php -v” and grab the appropriate file from php.net instead. I just recompiled the GD portion of PHP 5.2.14, since I wanted a perfect match between my php engine and the extension. The instructions below (except curl which needs to be modified) work.

NOTE: If you’re compiling on a G5 machine you’ll need to tell the compiler that you want to build/configure for a ppc64 target so instead of the below configure command you need to use this:

MACOSX_DEPLOYMENT_TARGET=10.5 CFLAGS=" -arch ppc64 -g -Os -pipe -no-cpp-precomp" CCFLAGS=" -arch ppc64 -g -Os -pipe" CXXFLAGS="-arch ppc64  -g -Os -pipe" LDFLAGS=" -arch ppc64  -bind_at_load" ./configure --with-zlib-dir=/usr --with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/X11R6 --with-freetype-dir=/usr/X11R6 --with-xpm-dir=/usr/X11R6
cd /SourceCache
curl -O http://www.opensource.apple.com/source/apache_mod_php/apache_mod_php-44.2/php-5.2.8.tar.bz2
tar xjvf php-5.2.8.tar.bz2
cd /SourceCache/php-5.2.8/ext/gd
phpize
./configure --with-zlib-dir=/usr --with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/X11R6 --with-freetype- dir=/usr/X11R6 --with-xpm-dir=/usr/X11R6
make
make test
make -n install

The last command will simulate the installation process. Make sure the stuff is getting installed in /usr/lib/php/extensions/no-debug-non-zts-20060613

make install

Now we need to modify our php.ini file and tell the php5 engine of the availability of this new module. To do this you need to copy php.ini.default to php.ini (in /etc directory). For details of why have a look at this article.

cd /etc
cp php.ini.default php.ini

Edit the newly created/copied php.ini using your favourite editor. Add the following line to the appropriate location (read the comments in the file to find the location):

extension=gd.so

Still in the same file find the variable “extension_dir” and change it’s value to “/usr/lib/php/extensions/no-debug-non-zts-20060613” path instead of “./”. Save the php.ini and use the following command to see if GD extensions are available:

server:etc root# php -i |grep GD
GD Support => enabled
GD Version => bundled (2.0.34 compatible)

Done. Restart Apache service from the server manager (just for the sake of completeness).
