[maplab-users] problem using preview in MapEdit

[Paul Spencer]

Matt,

if you have got everything set up right, you should have a temporary 
directory that is used for map and image files.  This directory is also 
accessible through your web server.  At DM Solutions, we typically set 
this up to be /tmp/ms_tmp/ with an alias for /tmp/ in the apache 
httpd.conf file.  The reasons are somewhat historical but basically stem 
from a linux background.  On your system, this would probably translate 
to d:\tmp\ms_tmp\.

The tutorial.map file is configured for this setup.  A MAP file has a 
web object that defines both the physical path to the temporary 
directory and a web-accessible path to the same directory.  The 
tutorial.map file comes with these settings configured for the DM 
Solutions default settings /tmp/ms_tmp/ and /tmp/.

The error message appears to be indicating that the /tmp/ms_tmp/ 
directory doesn't exist, so you will need to either change the MAP file 
or your system.  On Windows, you can (or should) specify a drive letter 
as well (i.e. d:/tmp/ms_tmp/), but it should default to the same drive 
as everything is installed on.

You will also have to make sure that MapLab is configured for the same 
paths as you decide to use in your MAP files.

Cheers,

Paul
