When config php source, there is an error:
xml2-config not found. Please check your libxml2 installation
In Synaptic, there is only libxml2 installed, while libxml2-dev is not installed. Just install libxml2-dev.
Or we can intall libxml2 using source code, like below:
sudo wget ftp://xmlsoft.org/libxml2/libxml2-2.6.28.tar.gz sudo tar -zxvf libxml2-2.6.28.tar.gz cd libxml2-2.6.28/ ./configure make sudo make install
