Code:

rm -f /usr/lib64/libxml2.so.2

Fixed it.

Do this as well to avoid other problems:

Code:

ln -s /opt/xml2/lib/libxml2.so.2 /usr/lib64/libxml2.so.2

Changing the symlink works but with a gotcha. Sometimes a yum update/upgrade will force the system to rebuild the library links and when that happens, it will revert the symlink back to the original libxml2 library that came with the distro.

Overwrite the /usr/lib64/libxml2.so.2.6.26 file with the /usr/local/lib/libxml2.so.2.7.7 file. This will work for as long as the libxml rpm package is not updated.

Digging a little bit deeper on this, came cross http://www.eyrie.org/~eagle/notes/rpath.html

I think something wrong with RPATH built into the binary, it can be checked with

Code:

readelf -d lsphp5 | grep RPATH

If somehow /usr/lib(64) got into RPATH before /opt/xml/lib, it could cause wrong library loaded. there is a tool called "patchelf" which can update RPATH built into ELF binary.

The root cause might be the GNU build tool chain, autoconf, libtool, etc.
