What is your full configur eline fro PHP 4 ?

These are all the options used to configure PHP/4.1.0. It's an excerpt from a script used in an RPM build.

./configure \
	--prefix=/usr \
\
	--with-apxs="`rpm -ql xalkina-apache | grep bin/apxs`" \

You need to compile MySQL support in with this switch:
--enable-mysql=/path/to/mysql

The bundled libraries conflict with the libraries mod_php3 uses.

Not a bug > bogus

Solves the problem, but should I notice that it happened even without php3...

Is there any documentation on this kind of problems? Even now that I know the solution, I cannot find anything in the search.

After ./configure has finished it prints this:

+--------------------------------------------------------------------+
|                        *** WARNING ***                             |

| You chose to compile PHP with the built-in MySQL support.  If you  |

| mod_perl) you must NOT rely on PHP's built-in MySQL support, and   |
| instead build it with your local MySQL support files, by adding    |
| --with-mysql=/path/to/mysql to your configure line.                |
+--------------------------------------------------------------------+

I think that's clear enough :)

Mind you, but this has nothing to do with it!

First of all, the server crashes even when the only module using MySQL loaded is php4. mod_roaming isn't using MySQL, mod_dav isn't using MySQL, and none of the default Apache modules is using MySQL.

Second, it was never compiled with the bundled MySQL files, it was always, repeat: ALWAYS, compiled --with-mysql=/usr.

Third, the notice does not suggest using the --enable-WHATEVER way :-)

BTW, the change I notice in the new module, is this: it does not link with libmysqlclient.so & libpthread.so anymore. (Same thing happens with PHP/3 that worked correctly). I originally though it had something to do with threads, that's why I added the --without-tsrm-whatever options to configure.

Similar thing happened when trying to include OCI8 support with php4. This time, apache SIGSEGVd.

After doing some search on Google, got to this page http://phpora.sourceforge.net/scenario_401-816.php, suggesting that Apache should be linked with pthread.

Rebuilding apache with -lpthread and than using --with-mysql & --with-oci8 as described in PHP documentation to build php4, everything works just fine!
