Tip : building Apache modules under Compaq Tru-64 Unix (formerly Digital Unix / OSF1)
> Guys,
>
> Those of us with Tru-64 often run into some interesting problems
> when buiilding Open Source software, particularly software which does not
> come with a configure script. The recent upgrade to v5.0 of Tru-64 caught
> out a lot of the configure scripts, but this tip is for those who have to
> 'wing it' completely.
>
> Current Apache releases contain the facility to build your httpd
> executable with support for dynamically linked modules (DSO). This means
> that your httpd executable no longer gets bigger with each successive
> module added to it. This is accomplished via the 'apxs' tool.
>
> PyApache is a module designed to speed up the execution of Python
> CGI scripts running under the Apache webserver. It comes with a single
> README containing a line which shows you how the suggested APXS command.
> Because of the nature of the Tru-64 compilation/linking environment, the
> supplied script will *not* work properly.
>
> To build PyApache under Tru-64, save this in a script called
> 'apxs.sh' or similar :
>
> #!/bin/ksh
> PYTHON="/usr/local/python-1.5.2"
> PYVER="python1.5"
> PYTHONLIB=$PYTHON/lib/$PYVER
> PYINC=${PYTHON}/include
> APACHEBIN=/usr/local/pyapache/bin
>
> echo "Building ${MODULE}"
> $APACHEBIN/apxs \
> -c \
> -Wl,"-shared -expect_unresolved '*'" \ #
> essential for Tru-64
> -I${PYINC} \
> -L${PYTHONLIB} \
> -L${PYTHONLIB}/config \
> -lpython1.5 \
> -lm \
> -lpthread \
> ${MODULE}.c
>
> if [ $? -eq 0 ]; then
> echo "Installing ${MODULE}"
> $APACHEBIN/apxs \
> -i \
> -a \
> ${MODULE}.so
> fi
>
> The net payoff for this effort was an increase from 15
> requests/second to over 58 requests/sec on our Alpha. Definitely worth it
> ! Note that the script above should work for most Apache modules which
> support DSO - you'll just need to change the include and library paths.
> Other options such as threading may or may not suit your environment. Your
> version of Python may differ, and so may the location of your Apache
> executables. Some installs have apxs in apache/sbin instead of apache/bin,
> but thats purely personal choice. If the build works, you should see apxs
> output indicating that httpd.conf is being updated. Please consult the
> apxs manpage (under apache/man) for further details re the options you
> need to pass apxs. The above script uses Korn shell syntax - it may need
> to be modified if you prefer another shell. Don't forget to read the
> INSTALL and README files to ensure that all necessary configuration is
> done before restarting Apache. Finally, my apologies for the size of this
> post !
