I tried to install the mongodb driver for PHP on Amazon Linux.
sudo pecl install mongo, I get the error message:
fatal error: openssl/evp.h: No such file or directory
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:
PHP’s guide: http://php.net/manual/en/mongo.installation.php
evp is high-level cryptographic functions.
Try to install development libraries:
sudo apt-get install libssl-dev
yum install openssl-devel
