# HP-UX specific installation notes

This section contains notes and hints specific to installing PHP on HP-UX systems. (Contributed by paul_mckay at clearwater-it dot co dot uk).

> Note: These tips were written for PHP 4.0.4 and Apache 1.3.9.

1. You need gzip, download a binary distribution from `http://hpux.connect.org.uk/ftp/hpux/Gnu/gzip-1.2.4a/gzip-1.2.4a-sd-10.20.depot.Z` uncompress the file and install using swinstall.

2. You need gcc, download a binary distribution from `http://gatekeep.cs.utah.edu/ftp/hpux/Gnu/gcc-2.95.2/gcc-2.95.2-sd-10.20.depot.gz`. uncompress this file and install gcc using swinstall.

3. You need the GNU binutils, you can download a binary distribution from `http://hpux.connect.org.uk/ftp/hpux/Gnu/binutils-2.9.1/binutils-2.9.1-sd-10.20.depot.gz`. uncompress this file and install binutils using swinstall.

4. You now need bison, you can download a binary distribution from `http://hpux.connect.org.uk/ftp/hpux/Gnu/bison-1.28/bison-1.28-sd-10.20.depot.gz`, install as above.

5. You now need flex, you need to download the source from one of the http://www.gnu.org mirrors. It is in the non-gnu directory of the ftp site. Download the file, gunzip, then tar -xvf it. Go into the newly created flex directory and run ./configure, followed by make, and then make install.

   If you have errors here, it's probably because gcc etc. are not in your PATH so add them to your PATH.

6. Download the PHP and apache sources.

7. gunzip and tar -xvf them. We need to hack a couple of files so that they can compile OK.

8. Firstly the configure file needs to be hacked because it seems to lose track of the fact that you are a hpux machine, there will be a better way of doing this but a cheap and cheerful hack is to put lt_target=hpux10.20 on line 47286 of the configure script.

9. Next, the Apache GuessOS file needs to be hacked. Under `apache_1.3.9/src/helpers` change line 89 from echo "hp${HPUXMACH}-hpux${HPUXVER}"; exit 0 to: echo "hp${HPUXMACH}-hp-hpux${HPUXVER}"; exit 0

10. You cannot install PHP as a shared object under HP-UX so you must compile it as a static, just follow the instructions at the Apache page.

11. PHP and Apache should have compiled OK, but Apache won't start. you need to create a new user for Apache, e.g. www, or apache. You then change lines 252 and 253 of the `conf/httpd.conf` in Apache so that instead of

        User nobody
        Group nogroup

    you have something like

        User www
        Group sys

    This is because you can't run Apache as nobody under hp-ux. Apache and PHP should then work.
