I have ISPConfig 3.1 on Debian wheezy with php 5.4 and php 5.3. I am trying to install php 7.1 on the same server according to this manual for Debian Jessie: https://www.howtoforge.com/tutorial/how-to-install-php-7-on-debian/ and of course it does not work. In the step "make" it says: "No targets specified and no makefile found. Stop."
I also found this instruction: https://www.cyberciti.biz/faq/installing-php-7-on-debian-linux-8-jessie-wheezy-using-apt-get/, however I cannot use it because I need php5.4 and PHP 5.3 on my server as well.
Is it feasible?
If someone else (like me) still needs to install php 7.1 or newer on Debian 7.X (wheezy), please be informed that I followed this instruction (just scroll down to
Configuration for Debian 7.x “Wheezy”section) and it worked for me like a charm!
