I'm a newbie trying to install PHP 5. I used apt to install libxml2, but when I try to configure PHP, it returns the following error...

checking whether to enable LIBXML support... yes
checking libxml2 install dir... no
configure: error: xml2-config not found. Please check your libxml2 installation.

When I run locate libxml2, I can see the following...
/var/cache/apt/archives/libxml2-dev_2.4.19-4woody1_i386.deb
/var/cache/apt/archives/libxml2_2.4.19-4woody1_i386.deb
/var/lib/dpkg/info/libxml2.list
/var/lib/dpkg/info/libxml2.postrm

If anyone else has the same problem, you can download a libxml2 from gnome.org, then just extract it as normal and reconfigure php...

ftp://ftp.ussg.iu.edu/pub/gnome/sources/libxml2/
More mirrors - http://ftp.gnome.org/pub/GNOME/MIRRORS.html

tar -zxvf libxml2-x.x.x.tar.gz
cd libxml2-x.x.x
./configure
make
make install

cd php-x.x.x
./configure (--help)

This Post was useful. I got the same problem with php-5.0.0RC2 on Debian SID. I just needed to download and install libxml2 with standard configuration: (./configure) and it worked !

Thanks !

Hi,
A simpler solution is to install a libxml2-devel rpm package.

do i need to re-./configure php5 after i ./configure libxml2-devel ?

Mine's not working unfortunately...

pentium:~/download/libxml2-2.6.5# ./configure
<ETC>
pentium:~/download/libxml2-2.6.5# make
-bash: make: command not found
pentium:~/download/libxml2-2.6.5# make test
-bash: make: command not found
pentium:~/download/libxml2-2.6.5# make install
-bash: make: command not found
pentium:~/download/libxml2-2.6.5#

I got this error while doing installation of libxml2

./configure
make

Very useful thread... I give 10 out of 10. Sammy22, that was the first thing i did..to download the rpm and install it but that doesn't work. You have to get .tar.gz and install it i guess.... Thanks ridertech.

Try to install libxml2 developement packages.
With Debian:
apt-get install libxml2-dev

i get the package in http://developer.bluesystems.com.br and compile using Debian 4.0 and run ....

i can open the link you gave. so i google around and found this

but thanks for this great thread, i encountered the same problem

Hi there... with debian/ubuntu, simply install build-essential and libxml2-dev

Hope this helps...

"sudo apt-get install libxml2-dev" will fix this dependency issue on Debian/Ubuntu derivatives...

Tank you very much, just that i need.
Very good place to know about linux.

Hi,
In ubuntu you should use the libxml2-devel bundle to be install, after that the configuraiton goes ok.

Thanks a lot
George
