I am fairly new to Linux (just getting set up using the Mint 16 distro), and I got everything working correctly with my Apache 2.4.9 with MySQL and PHP5.5, but I am using this for local Web development, and my host only has PHP5.3 installed. In order to make sure I don't use features that won't work in production, I want to install the older version instead of 5.5.

I downloaded the PHP-5.3.28 source tarball, but when I ran the configure script, it says:

configure: error: xml2-config not found. Please check your libxml2 installation.

Executing dpkg -l *xml* returns:

As you can see, libxml2:amd64 (I have a 64-bit system) is installed.

Could you direct me as to 1. what is wrong that it isn't recognizing it/finding the needed config file and 2. Whether proceeding with a make/make install of this standalone package will work without breaking the php functionality.

I had some trouble getting it set up this far (mainly because I'm in a steep learning curve for Linux right now), and I really don't want to have to go through that again, so I would rather leave it at 5.5 if it is too risky. :)

All you need to do is to install package libxml2-dev via:

sudo apt-get install libxml2-dev

See: How to fix error with xml2-config not found when installing PHP from sources?

In case of problems, update the list first by:

sudo apt-get update

  • Just required, sudo apt-get update first.

  • Installing the dev package doesn't help. I have both libxml2 and libxml2-dev installed band the xml2-config is still missing.
