Problems upgrading to PHP 5
I have installed PHP5 on our server (Red Hat Enterprise AS 3). I modified my httpd.conf file to load the PHP5 module. When I attempt to start Apache, I receive the following error:
"Cannot load /usr/lib/httpd/modules/libphp5.so into server: /usr/lib/httpd/modules/libphp5.so: undefined symbol: xmlXIncludeProcessFlags"
I tried doing a few searches on the error but couldn't find anything. Does anyone have any suggestions?
Thanks!

How did you install PHP5? What version of Apache are you using? If you installed PHP5 from source, please post the configure command you typed so we can see how it's setup.
Peace...

Yeah I installed it from source. I ran the following configure command:
./configure --with-apxs2=/usr/sbin/apxs --with-mysql
The server is running Apache 2.0.46

I found that symbol on this site, which looks like PHP5 is looking for a libxml2 library, of some sort. Do you have libxml2 installed on your system? I would do this to see:
$ su
# find / -name "*xml2*"
and post the results here.
Peace... |

You're probably onto something here. When I initially tried running the configure command for the php install, I received an error that the version of libxml that was installed was too old. So I installed/upgraded to libxml2 2.6.24 and the configure command ran just fine... so I assumed all was OK.
Here's the results from the command you gave me:

Thanks for posting that. I believe here is a possible source of conflict:
Quote:
/usr/bin/xml2-config
/usr/include/libxml2
/usr/lib/libxml2.a
/usr/lib/libxml2.la
/usr/lib/libxml2.so
/usr/lib/libxml2.so.2
/usr/lib/libxml2.so.2.5.10
/usr/lib/python2.2/site-packages/drv_libxml2.py
/usr/lib/python2.2/site-packages/libxml2.py
/usr/lib/python2.2/site-packages/libxml2mod.a
/usr/lib/python2.2/site-packages/libxml2mod.la
/usr/lib/python2.2/site-packages/libxml2mod.so
/usr/lib/xml2Conf.sh
/usr/local/bin/xml2-config
/usr/local/include/libxml2
/usr/local/lib/libxml2.so.2.6.24
/usr/local/lib/libxml2.so.2
/usr/local/lib/libxml2.so
/usr/local/lib/libxml2.la
/usr/local/lib/libxml2.a
/usr/local/lib/xml2Conf.sh
|
Both /usr/lib and /usr/local/lib can be used to find shared libraries at runtime. You have two different libxml2 installations when you only want one. Since /usr/local/lib/libxml2.so.2.6.24 is newer than the 2.5 version in /usr/lib, you will need to find a way to remove the libxml2 installation in /usr (meaning, the files in /usr/lib, /usr/include, and so on) will neeed to be removed. See if you can use RedHat's package manager to uninstall libxml2 in /usr.
Peace... |

Hello again.
I ran the following prm command to uninstall libxml2:
rpm -e libxml2 --nodeps
I then ran a query to make sure it had been removed:
rpm -q libxml2
...which confirmed that the libxml2 rpm was no longer installed
I reran the find command, and it still showed (some but not all) libxml files in /usr/lib and I am still getting the same error as before when I try to start Apache with the php5 module loaded. I am a bit of a php noob, and am unsure of the next step... should I remove files manually? Perhaps it would have been a lot easier if I installed the update as a prm instead of a tar... but too late for that.
Also, here was the result of the latest find command:

Ok, I would do this:
$ su
# cd /usr/bin
# rm xml2-config
# cd ../include
# rm -fR libxml2
# cd ../lib
# rm -fR libxml2*
# rm xml2Conf.sh
# /sbin/ldconfig
# exit
$
Make sure /usr/local/bin is in your path.
Then I would try it again.
Peace...

I followed your instructions and removed the files. When I tried to start Apache, I recieved an error that libxml2.so.2 could not be found. I then decided to copy the newer libxml files to the older version's directories. After doing this, Apache actually started successfully (even loading the php5 module). However when I viewed php files on the site, the page is completely blank. I commented out the load module for php 5, and it works as usual. So I dunno.....

So, is everything working now or are you having PHP issues?
It looks like Apache was built against libxml2 in /usr, which is why Apache complained. Sorry about that.

To be on the safe side, I would recompile and install PHP5 just to make sure it links against the libxml2 files now in /usr.

Still no luck loading the PHP 5 module. Is there an easy way for me to install libxml2 into the /usr instead of /usr/local?

Can you post the errors you're getting now?
You should be able to move the libxml2 files in /usr/local out of the way, re-run ldconfig, and then rebuild PHP5 as an Apache DSO to make sure it links against libxml2 in /usr.
Peace...

When I load the php 5 module, all PHP pages show up completely blank.
When I run ldconfig it reports: /usr/lib/libxml2.so.2 is not a symbolic link
