More Apache/PHP installation puzzles

This all started when I had trouble installing Apache/PHP (see earlier posts 
Re: Apache/PHP installation puzzle).  As this problem is a bit more general I 
thought I would start a new thread.
In a nutshell, the PHP part of the installation fails without any obvious 
errors.  In order to find out what's going on I decided to remove every vestige 
of Cygwin from the W2K box and re-install the minimum required to ivestigate 
this problem.

This is the story .....

1. Install Cygwin with nano, apache, and mod-php4.  NOTE.  Install Cygwin 1.5.3-
1 because there are issues with 1.5.4-1 that prevent processes being stopped 
2. Start the apache server ....

$ /usr/sbin/apachectl start
[Tue Sep 16 14:54:56 2003] [alert] httpd: Could not determine the server's fully
 qualified domain name, using for ServerName
/usr/sbin/apachectl start: httpd started

3.  Using the Windoze browser, visit http://localhost/.  See the expected 
default Apache installation page - so far, so good.
4.  Using the favourite nano editor, create the xyzzy.php script and put it 
in /var/www/htdocs.  The script contains the simple PHP function call <?phpinfo
()?> and nothing else.
5.  Visit http://localhost/xyzzy.php and the script is simply presented on the 
page - a clear indication that the PHP is not being translated.
6.  Check out /etc/apache/httpd.conf and there is no mention of php in here.  
What's needed are lines of the form:

LoadModule php4_module lib/apache/libphp4.dll
AddModule  mod_php4.c

Add these and try again ....
$ /usr/sbin/apachectrl start
Syntax error on line 236 of /etc/apache/httpd.conf:
Cannot load /usr/lib/apache/libphp4.dll into server: dlopen: Win32 error 126
/usr/sbin/apachectrl start: httpd could not be started

7. As error 126 is basically 'file not found', we'll check for the existance of 
the libphp4.dll.  

$ updatedb
$ locate libphp4

.... no trace of the DLL to be found!!!

8.  Now this is interesting!

$ cd /usr
$ ls
doc  etc  include  info  local  man  sbin  share  src  ssl  tmp  var

Note the lack of a lib directory.  However...

$ cd lib

Administrator@zebedee /usr/lib

...?Que!!?  How can one cd to a directory that doesn't exist. Not only that, but

$ ls
apache		libc.a		libhistory.a		libxm12.a


libbz2.dll.a	libgmon.a

And so /usr/lib exists but is partially invisible.  Interestingly, Windows 
can't see this directory either.  Hence one possible explanation of why the dll 
won't load.

9.  Progressing further ....

$ cd /usr/lib/apache
$ ls
libproxy.dll	mod_autoindex.dll	mod_imap.dll	mod_setenvif.dll


mod_auth_dbm.dll	mod_headers.dll	mod_rewrite.dll	new

$ ls new

Administrator@zebedee /usr/lib

No trace of the missing dll - a possible second reason why the Windows load 

10.  Seems that something must be going wrong in the post install script too!  
What we'll do is manually install the package and see what's going on.  Copy 
the .tar.bz2 file to / and then:

$ bunzip2 apache-php-4.3.0-2.tar.bz2

Administrator@zebedee /
$ tar -xvf apache-php-4.2.0-2.tar

Administrator@zebedee /

This unpacks everything and doesn't run the post install script.  Now we'll run 
the post install script and see what's going on:

Administrator@zebedee /etc/postinstall
$ cd /etc/postinstall/

Administrator@zebedee /etc/postinstall
$ ./
usage: rebase -b BaseAddress [-Vdv] [-o Offset] [-T FileList | -] Files...

Administrator@zebedee /etc/postinstall

So, it seems that either rebase is being called incorrectly or the argument 
list is invalid.

11. The check the argument list, add the following line 
to /etc/postinstall/ and re-execute it.


echo ${rebase_dlls} immediately following the line starting "rebase_dlls="$"

Re-running gives:

Administrator@zebedee /etc/postinstall
$ ./
/usr/lib/apache/libphp4.dll /usr/bin/cygbz21.0.dll /usr/bin/cygcrypto.dll /usr/b
in/cygintl-1.dll /usr/bin/pq.dll /usr/bin/cygxml2-2.dll /usr/bin/cygz.dll /usr/b
usage: rebase -b BaseAddress [-Vdv] [-o Offset] [-T FileList | -] Files...

Administrator@zebedee /etc/postinstall

Checking the list of file names we find that 
neither /usr/lib/apache/libphp4.dll nor 
/usr/bin/cygcrypto.dll exists.

Looking at I'm not sure that the call to rbase is right either - 
but I've got to too many errors now.

So there we have it - the story of trying to install Apache/PHP.

I hope that I've provided enough information for the developers/maintainers to 
quickly come to a solution as having PHP available in a mixed Linux/Window 2K 
box will be very useful for development purposes.
