[Chameleon] New User, Needs Help!

[David Bradshaw]

Dear Users,

I am VERY new to Chameleon and have a few questions.  First of all, I am
using this on a  Windows XP and Apache platform.  I am looking to
install MS4W and Chameleon 1.99beta.  I've downloaded from DM Solutions
the following zip files:
(1) http://www.maptools.org/dl/ms4w/ms4w_0.8.zip
(2) http://www.maptools.org/dl/ms4w/chameleon_ms4w-1.99beta1.zip

I have unzipped them to my hard drive. I have been following the
chameleon installation instructions on the Wiki site but seem to have
trouble with tmp folders and location/permissions:
http://www.maptools.org/chameleon/wiki/ChameleonInstallationInstructions


Question number 1.  Where should these be "installed?"  Is there a good
example of the file structure hierarchy? I've unzipped them to c:\ms4w
(I placed chameleon under the folder called apps) and was able to get
the localhost to open the demos but I get several broken links. For
example, in the http://localhost/chameleon/samples/ when I click on ROI
Widget Pack Sample using widgets from the ROI widget pack I get the
following error:

Fatal error: Call to undefined function: ms_newsymbolobj() in
C:\ms4w\apps\chameleon\htdocs\widgets\TrueNorth\TrueNorth.widget.php on
line 213

Again, for example, in the http://localhost/chameleon/samples/ when I
click on Enhanced Widget Pack's Sample using XML Theme Legend I get the
following message returned: 

Warning: [MapServer Error]: msSaveImage():
(../tmp/ms_tmp/108784539119681.png) in
C:\ms4w\apps\chameleon\htdocs\widgets\Scalebar\Scalebar.widget.php on
line 385

Fatal error: Failed writing image to ../tmp/ms_tmp/108784539119681.png
in C:\ms4w\apps\chameleon\htdocs\widgets\Scalebar\Scalebar.widget.php on
line 385 

I get a lot more error messages if I do not have the folder
"c:\tmp\ms_tmp."  I do have this same-named folder under c:\ms4w\ and
c:\ms4w\chameleon.

Would the failed to write to /tmp/ms_tmp be a apache permissions
problem?  It seems to access the tmp folders ok but fails to write to
them.  Is there anything special that needs to be done in apache other
then to create an alias in httpd.conf?

Below is my httpd_chameleon.conf

Alias /ms_tmp/ "../ms4w/tmp/ms_tmp/" 
<Directory "/tmp/ms_tmp"> 
   Options Indexes MultiViews 
   AllowOverride None
   Order allow,deny
   Allow from all 
</Directory>  

Alias /chameleon/admin "/ms4w/apps/chameleon/htdocs_admin" 
<Directory "/ms4w/apps/chameleon/htdocs_admin"> 
  AllowOverride None 
  Options Indexes FollowSymLinks Multiviews  
  Order allow,deny 
  Allow from all 
</Directory> 
 
Alias /chameleon/docs "/ms4w/apps/chameleon/docs/html" 
<Directory "/ms4w/apps/chameleon/docs/html"> 
  AllowOverride None 
  Options Indexes FollowSymLinks Multiviews  
  Order allow,deny 
  Allow from all 
</Directory> 
 
Alias /chameleon/samples "/ms4w/apps/chameleon/samples/htdocs" 
<Directory "/ms4w/apps/chameleon/samples/htdocs"> 
  AllowOverride None 
  Options Indexes FollowSymLinks Multiviews  
  Order allow,deny 
  Allow from all 
</Directory> 
 
Alias /chameleon "/ms4w/apps/chameleon/htdocs" 
<Directory "/ms4w/apps/chameleon/htdocs"> 
  AllowOverride None 
  Options Indexes FollowSymLinks Multiviews  
  Order allow,deny 
  Allow from all 
</Directory> 
 

I think this a great program with a lot of potential and I just need a
little help getting out of the starting blocks!


Thanks in advance,

David
