php 5.04 with apache 2.0.54

[one2001boy@yahoo.com]

Hello,

I can build php 5.04 with apache 1.33 statically
with the apache configuration option: --activate-module=src/modules/php5

How can I build php 5.04 with apache 2.0.54 statically?
It seems that the information I have only shows how to build php as a
dynamical module of apache.

Thanks.

I don't know the answer to your question, but why would you want to
build PHP statically?

the performance will be better with static link. shared module is not so
good in performance.

This is the first time I hear a thing like that. There is a bit of an
overhead when apache starts up, as each of the httpd processes has to
load module by invoking dlopen and then resolving each symbol by
performing dlsym, but after that all the functions are defined and
addressable, just as if they were loaded in the same code segment.
$APACHE_HOME/modules/libphp5.so is loaded in a separate segment which
is mapped into the httpd process address space. You might have a choice
of how to link PHP5 but you don't have that choice when it comes to many
other shared libraries. Here is what the address of space of apache httpd
process looks like on FC3:
# ps -fp 5233

nobody 5233 5221 0 20:52 ? 00:00:00 /opt/apache/bin/httpd -k start

So, what would you gain by linking just one of those libraries statically?
Is you statement based on experience, measurement or something else? There
are many ways to achieve better performance, like disabling .htaccess for
instance or saving sessions to memory (MM module). In other words, even
if you manage to do what you want to do, all that you will save is a few
milliseconds upon Apache startup and nothing else. The price to pay will
be a highly non-standard installation which is hard to extend and
difficult to handle. Hardly worth the effort.
