Enable IMAP PHP module on OSX Snow Leopard Server 10.6

You can safely delete all the extension lines that end with .dll because those are for Windows.

Remove the semi-colon (;) from your extension line referencing imap.so and restart. The semi-colon character makes the line a comment (i.e., ignore this line).

Hi.

Nice guide but it didn't work fully for me. My main goal was to enable IMAP-SSL to enable my PHP scripts to connect to GMail using IMAP. I have a Core 2 Duo Mac Mini with MAMP installed.

Problem 1.
In Step 6 when trying to build the imap extension I got the following error:
/usr/include/php/ext/pcre/php_pcre.h:29:18: error: pcre.h: No such file or directory

Solution
Copy the pcre.h file from the downloaded PHP source to your /usr/include dir:
sudo cp ../pcre/pcrelib/pcre.h /usr/include/php/ext/pcre/

Problem 2
When starting the Apache server again I got the following error in the PHP log:
[18-Jan-2011 22:11:31] PHP Warning: PHP Startup: Unable to load dynamic library '/Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-20090626/imap.so' - dlopen(/Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-20090626/imap.so, 9): no suitable image found. Did find:
/Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-20090626/imap.so: mach-o, but wrong architecture in Unknown on line 0

Why?
After hours of searching I figured out that the compiled binary imap.so only contained binary for the x86_64 architecture. My MacMini has a 64-bit CPU so the problem isn't there. The problem is that the php binary shipped with MAMP is only built for the i386 architecture, making them incompatible.

How:
If you run the command 'lipo -info <filename>' you will see which architectures the binary supports. Try running it on file php-5.3.1/ext/imap/modules/imap.so and compare the output with the php binary located in /Applications/MAMP/bin/php5.3/bin/

Solution:
Rebuild the imap extension, this time targeted for both i386 and x86_64 architectures. We have to rerun step 5 with some modifications:
cd php-5.3.1/ext/imap
make clean
phpize
MACOSX_DEPLOYMENT_TARGET=10.6 \
CFLAGS="-arch i386 -arch x86_64 -g -Os -pipe -no-cpp-precomp" \
CCFLAGS="-arch i386 -arch x86_64 -g -Os -pipe" \
CXXFLAGS="-arch i386 -arch x86_64 -g -Os -pipe" \
LDFLAGS="-arch i386 -arch x86_64 -bind_at_load" \
./configure --with-imap=/usr/local/imap-2007 --with-kerberos --with-imap-ssl=/usr/

Then continue with step 6.

It took me about 15 painstaking hours to figure this out. Hope I can help someone out there so you don't have to go through the same frustrating process I had to go through.

[sigh]

I'm getting the following errors attempting to make the module in OS X 10.6.8. If anyone could assist I would appreciate it.

My Snow Leopard Server is running 5.3.4 according to info.php. Is it important that the versions match exactly when following these instructions or do I have to find 5.3.0?

And just to clarify, you're saying 5.3.0 is required for the imap module and not to have 5.3.0 running on the server?
