Error while installing mongo driver for PHP on amazon linux

Question

I tried to install the mongodb driver for PHP on Amazon Linux. While running sudo pecl install mongo, I get the error message:

fatal error: openssl/evp.h: No such file or directory
 #include <openssl/evp.h>
                         ^
compilation terminated.
make: *** [io_stream.lo] Error 1
ERROR: `make' failed

PEAR Version: 1.9.5 PHP Version: 5.3.29

I installed gcc which helped me progress further with the install till this error.

The best Guide I was able to find was here: http://jonathanhui.com/install-mongodb-amazon-linux PHP's guide: http://php.net/manual/en/mongo.installation.php

Answer 1

evp is high-level cryptographic functions.

Try to install development libraries:

Ubuntu: sudo apt-get install libssl-dev

CentOS: yum install openssl-devel

Answer 2

The right package to install is not libssl-dev but

sudo apt-get install pkg-config

and now you can execute

sudo pecl install mongodb

Don't forget to add extension=mongodb.so to your php.ini file.

To know which php.ini file is loaded you can create and simple php file on vps

<?php
   php_info()
?>

Example directory php.ini in phpinfo()
