Error installing PHP7.1 with apache2 on debian 9

Question

Hello I installed the apache with debian's 9 installation. Then installed php7.0 with apt-get but I need to install php7.1, at first I do

# su
# apt-get purge php7.0 

so I downloaded from http://php.net/downloads.php php 7.1.10 and make this

# ./configure --with-mcrypt
# make
# make install

but phpinfo() get the php7.0, so I make

# su
# apt-get purge php7.0 
# apt-get autoremove php7.0

and know phpinfo() is not working. I sumed that now php is not installed.

Then downloaded from http://php.net/downloads.php php 7.1.11 (new today) and inside

# tar jxvf php-7.1.11.tar.bz2
# apt-get install build-essential
# apt-get install libxml2-dev libmcrypt-dev libjpeg-dev
# cd php-7.1.11
# ./configure --with-mcrypt --with-pdo-pgsql=/etc/postgresql/9.6/main --with-openssl=/usr/bin/openssl --with-zlib --with-apxs2=/usr/bin/apxs2

And between all the checks I get the next errors

Configuring SAPI modules

configure: error: Cannot find OpenSSL's <evp.h>

What's wrong with this?

Answer 1

use Sury repo for this (https://deb.sury.org/), this is a small script to add it to your repo list.

#!/bin/bash
# To add this repository please do:

if [ "$(whoami)" != "root" ]; then
    SUDO=sudo
fi

${SUDO} apt-get install apt-transport-https lsb-release ca-certificates
${SUDO} wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
${SUDO} sh -c 'echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list'
${SUDO} apt-get update

• Source: https://packages.sury.org/php/README.txt

It is far a better option to use Debian repo to install SW rather than to go manual, it will avoid you a lot of headaches :)

You may be missing SSL dev. Try this...

apt-get install libssl-dev

Likely this will solve your problem.

Tip: Anytime you're missing a file, use apt-get to find it's package...

apt-file search /evp.h | egrep '/evp.h$'
