I've tried to follow the instructions, with mixed success for the
individual steps, and no luck getting mapscript to load. Please see my
results interspersed with the instructions, below, and anyone with insight
into the problems I'm having please let me know.
Are there tools to help understand better what is/is not working when PHP
tries to load a DLL? There's got to be something more than "it worked" or
"it didn't"...?
Thanks,
Chris

Hi Chris,
it took me many hours to get cartoweb running under IIS, just to find
out that some plugin (I think it was the pdf export) did not work under
our IIS configuration. Finally, I switched back to Apache.
Anyway, I install PHP, mapserver and cartoweb the following way:
1. Get PHP running under IIS or Apache. There is a documentation on
php.net that works. If you are working with virtual directories
you *must* either set or not set or not set doc_root in php.ini. I
can not remember which one is correct - try. If I am not mistaken
it is the opposite of what some documentation said.
Done - PHP 5.2.3 installed and running under IIS 5.1 (I'm trying this on my
laptop with Windows XP for now) - doc_root is not set.
2. Setup error logging if it is not in php.ini. I usually log to a
file, i.e. "log_errors = On" and error_log = "{SOME_PATH}\php.log".
Tried everything - can't get any actual errors to be logged. Created the
file, set both NTFS and IIS permissions to allow anyone to write to it, set
the error_log to this file in PHP.ini (phpinfo() confirms that it's set),
ran various error-throwing codes but get no entries in the logfile - don't
know if logging is working or not, but I suspect not. Is this critical for
mapscript to work, or just a useful debugging tool?
3. Get a ms4w package from http://www.maptools.org/ms4w/. Make sure
it fits your PHP version. If you have 5.2.x the current ms4w 2.2.4
should work. Decompress it into some temp folder.
Done - downloaded and unzipped 2.2.4
4. Create a folder "Mapserver" somewhere and add it to the Windows
PATH variable. This way you do not need to put the dlls required
by mapserver into the Windows system path. Now log out an in again
or reboot if possible, so Windows rereads the system variables and
the new PATH is recognized.
Done - created C:\mapserver and put it in the Environment Variables->System
Variables PATH variable - confirmed by seeing it listed in phpinfo()
5. Now get Dependency Walker from http://www.dependencywalker.com/
and extract it somewhere. You will need it in step 8.
Done.
6. Get php_mapscript.dll from the ms4w package. It is located unter
{MS4W_TEMP_PATH}\Apache\php\ext. Copy it to the ext folder of your
PHP installation. I usually rename it to something like
php_mapscript_4.10.2.dll, so I know which version is currently
installed. Load the extension in the php.ini, e.g.
"extension=php_mapscript_4.10.2.dll". Make sure, that
extension_dir is correctly set in php.ini.
Done - but how can one know the version of the php_mapscript.dll - the file
itself has no version info, nor could I find other docs in the ms4w tree
that indicates which version of mascript is being used. I just left it as
php_mapscript.dll for now.
7. Copy the proj folder from ms4w and its content to C:\.
Done.
8. Finally, the libraries required by php_mapscript.dll have to be
copied to the folder created in step 4. In order to do this run
depends.exe and open php_mapscript.dll. It will tell you which
dlls are missing. Copy them from {MS4W_TEMP_PATH}\Apache\cgi-bin
to the folder created in step 4. Refresh the view in Dependency
Walker after copying, because there might be additional
requirements. Repeat this until no more missing dependencies are
reported. You may savely ignore dlls that show the timer, e.g
DWMAPI.dll, SHLWAPI.DLL.
Done. However, I get this warning for MPR.dll - I think from what I read on
the web that I can ignore this warning?
"Warning: At least one module has an unresolved import due to a missing
export function in a delay-load dependent module."
Now, php should be able to load the Mapscript extension. Check it with
the phpinfo() function.
Nope :( phpinfo() doesn't show anything about "mapscript", and the info()
function provided with cartoweb (which just tries to load mapscript and
then calls phpinfo) also gives warning that mapscript is not loaded.
The only 2 things that appeared anomalous when following the instructions
were my inability to get PHP error logging to work and the warning about
MPR.dll in the dependency walker - are either of those likely candidates
for why mapscript isn't loading?
If it does not, I have no idea why, could be a
version conflict or a wrong dll. It's difficult to determine without
seeing the actual system.
If mapscript is loaded, you should be able to install Cartoweb according
to the documentation.
I hope this helps a bit.

Dirk

I've been asked to work on an existing Mapserver site, including
redeploying it as a Cartoweb project. I have solid if not extensive
experience with web application development (PHP, MySQL, Mapserver,
ASP, ASP.NET), but not much experience with server setup and
maintenance. After a full 2 days of reading and experimenting, I still
cannot get a basic Cartoweb demo to run... hope I can get some
pointers to get setup.
The existing configuration is Windows Server 2003, IIS 6.0, Mapserver
4.6.0, PHP 5.1.2. There is a functioning Mapserver website running.
My first goal is to install Cartoweb and run the demos.
I downloaded cartoweb-withdemo-3.3.0.zip and unzipped it in it's own
new directory.
First of all, I cannot get the "prerequisites" going. I have copied
php_mapscript.dll to the PHP extensions directory, I have made sure
that cgi.force_redirect=0. When I go to cartoweb3 info.php I get the
error message "WARNING: can't load mapscript library".
Nonetheless, after wrestling with that problem for too long, I tried
to continue with the cartoweb install, hoping that maybe I'd gain some
more insight or ideas in the process. I executed the basic setup command:
php cw3setup.php --install --base-url
http://umaacorn.provost.ads.umass.edu/acorncw/cartoweb3/htdocs
but I get blank windows when I go to client.php or demoCW3.php... they
load but there's no HTML content.
I have tried dozens of other things - messing around with the IIS
configuration (currently it seems to be using php5isapi.dll, so I've
tried php-cgi.exe with no luck, but maybe I didn't set it up right).
I would love to have a step-by-step or a checklist to go by... but
will settle for help of any kind! Hope someone out there with similar
setup and/or experience will lend a hand, and I'll be glad to return
favors in the future!
Cheers,
Chris
