HP-UX 11.00
Binutils 2.12
GCC 3.0.4
GNU Make 3.79.1

mysql-3.23.49 (using GCC)
./configure --prefix=/opt/mysql

Have verified -lgcc being used in mysql build.

apache-2.0.35 (using GCC)
./configure --prefix=/opt/apache2

php-4.2.0 (using GCC)
./configure --prefix=/opt/php --enable-libgcc \
--with-apxs2=/opt/apache2/bin/apxs \
--with-mysql=/opt/mysql --enable-sockets

Start Apache:
/opt/apache2/bin/apachectl start

Error:
Syntax error on line 217 of /opt/apache2/conf/httpd.conf:
Cannot load /opt/apache2/modules/libphp4.so into server: Unresolved symbol: __umoddi3 (code)  from /opt/mysql/lib/mysql/libmysqlclient.sl.10
/opt/apache2/bin/apachectl start: httpd could not be started

Everything has been compiled with GCC.  Have used -enable-libgcc in PHP's compiling, but somehow I'm still having problems with this __umoddi3 not being resolvable.

The bug system is not the appropriate forum for asking support
questions. For a list of a range of more appropriate places to ask
for help using PHP, please visit http://www.php.net/support.php

This looks like a gcc problem. I've diagnosed problems
with Solaris+gcc where gcc will include libgcc symbols
in the object files but fails to tell the native linker
(/usr/ccs/bin/ld on solaris) how to resolve those
symbols. Therefore at runtime you get symbol resolution
failures.

Do you really have a shared version of libgcc? If so,
is it in your library path?

To link against libgcc.a statically, and as a minor
workaround (since this is partly gcc's fault), try this:

LDFLAGS="`gcc -print-libgcc-file-name`" ./configure --your-flags

If you are still having this problem, please open a bug
with mysql, as the unresolved symbol is coming from that
object. Thanks for using Apache and PHP.
