| | Answer : | This is an example that works for us. It may not work for you but its a start.
Before reinstalling PHP you need the libxml librarys.
wget ftp://ftp.gnome.org/pub/GNOME/sources/libxml2/2.4/libxml2-2.4.28.tar.gz
tar -pxzf libxml2-2.4.28.tar.gz
cd libxml2-2.4.28
./configure --with-zlib
make
make install
Check /etc/ld.so.conf for the line /usr/lib if its there don't worry about the next step, if its not then add it.
Then run ldconfig
Then create a symlink so PHP knows where to find the librarys :-
ln -s /usr/local/include/libxml2/libxml /usr/local/include/libxml
Before we added this line we were getting the following error on the PHP cofigure :-
checking for DOM in default path... not found
configure: error: Please reinstall the libxml >= 2.2.7 distribution
A search of google found nothing so we went hunting in the configure source.
The basic check does the following, if a directory is supplied int he configure line for the DOM librarys it looks for :-
DIR/include/libxml/tree.h (DIR being the path you supplied)
If it can't find it or its not supplied it then goes to /usr and /usr/local it then runs through adding /include/libxml/tree.h to each one looking for the librarys.
The symlink basically means that :-
/usr/local/include/libxml/tree.h exists and points to /usr/local/include/libxml2/libxml/tree.h
We also had to create one more symlink
ln -s /usr/lib/libxml2.a /usr/lib/libxml.a
This had the desired effect of allowing PHP to configure and build.
Update
We just tried the above install for php4.2.2 we got the following error :-
checking for libxml version... configure: error: libxml version 2.4.2 or greater required.
Removing the directory :-
/usr/local/include/libxml
and re-running
ln -s /usr/local/include/libxml2/libxml /usr/local/include/libxml
Fixed the error
