I try to install Solr PHP extension to my webserver. I already have an XAMPP server and I'm using PECL to install solr

$ cd /opt/lampp/bin

$ sudo ./pecl install solr-1.0.1

But I got the following error:

checking libxml2 install dir... /usr/lib
checking for xml2-config path...
configure: error: xml2-config not found. Please check your libxml2 installation.
ERROR: `/tmp/pear/temp/solr/configure --enable-solr=yes --enable-solr-debug=no --with-curl=
/usr --with-libxml-dir=/usr/lib' failed
During the installation it prompts me to input a path:

libxml2 install prefix [/usr] :

I have tried with enter and the /usr/lib

What shall I input there to not get an error? Or how shall I install to not get an error?

UPDATE:

I have now installed libxml2 through $ sudo yum install libxml2-devel

But I got some new errors when I try to install using PECL:
