Installing Mongodb with Lamp On Ubuntu ( Linux )

Question

I followed the following steps to install mongo's php drivers with lampp.

http://abstract2paradox.wordpress.com/2012/01/26/adding-mongo-db-driver-to-xampp/

When I start lampp its gives the following error

Warning: PHP Startup: Unable to load dynamic library '/opt/lampp/lib/php/extensions/no-debug-non-zts-20090626/mongo.so' - /opt/lampp/lib/php/extensions/no-debug-non-zts-20090626/mongo.so: wrong ELF class: ELFCLASS64 in Unknown on line 0

Any ideas?

Thanking you

This means that your PHP is compiled in 32-bit mode, but the mongo extension as 64-bit mode. I believe Apple's compiled PHP is in 32-bit mode as well, you can verify that with:

php -r 'echo PHP_INT_MAX, "\n";'

If that shows

9223372036854775807

you're on a 64-bit platform.

Now, in your case you will need to make sure that you compile the MongoDB extension with a 32-bit architecture. From http://artur.ejsmont.org/blog/content/how-to-build-mongodb-pecl-extension-in-32bit-for-php-52-on-macosx-snow-leaopard I believe you can do that with:

pecl download mongo
tar -xvzf mongo-1.2.7.tgz
cd mongo-1.2.7

CFLAGS="-m32"

phpize
./configure
make
make install

-thanx, but I am on linux ( Ubuntu ) – Imran Omar Bukhsh – Imran Omar Bukhsh Feb 22 '12 at 14:57
running php -r 'echo PHP_INT_MAX, "\n";' gives me 2147483647 – Imran Omar Bukhsh Feb 22 '12 at 15:48
do I need to type 'make install' at the end? – Imran Omar Bukhsh Feb 22 '12 at 15:50
Uh, yes, you need make install – Derick Feb 22 '12 at 16:05
well the problem still persists – Imran Omar Bukhsh Feb 23 '12 at 09:22
There can be a few reasons: You've used the wrong phpize (check whether you have more than one, I think Apple ships PHP (+ phpize) as well, and you need to use the one for lampp. It's also possible that ./configure picked up the wrong php-config binary, again, you need to use the one provided with LAMPP, and you can specify that with
```
./configure --with-php-config=PATH
```

indeed it was using the wrong php and specifying the path sovled the php bit of the problem....it still give the same error though...whilst compiling it says : checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu – Imran Omar Bukhsh Feb 27 '12 at 14:06
'which phpsize' says : /opt/lampp/bin/phpize – Imran Omar Bukhsh Feb 27 '12 at 14:09
command i used for configure : sudo ./configure --with-php-config=/opt/lampp/bin/php-config – Imran Omar Bukhsh Feb 27 '12 at 14:09

The problem was as is outlined by Derick above. Although the way the problem got solved was download a 32 bit version of the ubuntu os and running it as a virtual machine on my pc using vmware. Later followed the 'Manual Installation section' on this page for the php driver installation and it all worked. Got the php drivers from github as mentioned in the page.

Later i copied the file mongo.so from the php file extensions directory running on my virtual machine to my parent os and it all works now!
