Does anyone use the latest code with PERL Mapscript? If shp2img works
with my mapfile, is there anything else I can do to understand why my
new call for the mapObj fails?

I have verified that shp2img constructs an image that derives form my
mapfile. This part looks good. My mapscript code was written for
4.4.2, but the one function that is failing does not appear to have
significantly changed. I am not getting past construction of the
basic mapObj from the mapfile. Specifically, the call to :
my $map = new mapscript::mapObj( $mapfile ) or carp "Could not create
mapscript object from mapfile: $mapfile";
produces the error message. I also went into mapscript.pm and added
debug code there to be sure I was using the correct module. The low
level call is producing an unusable result.

Hi Joe,
A couple of things.
1) what version does you existing code work on?
2) There are probably two areas that you will need to change
a) the mapfile
b) the perl
I would start with using shp2img to make sure you mapfile can load.
It will at least print errors that you can read.
shp2img -m /path/to/file.map -o junk.png ...
Once you can get an image then you will probably have more luck
tracking down the various mapscript changes. These will depend on
what version of mapscript your code was written for.

Greetings Listers,
It has been a while since I deployed a new Mapserver application.
I have been leaning on old source on an old box to get the work
done. I have been given a new server to set up for our Air Force
project and have had some issues with getting my code to work.
First of all I am using Mapscript ala PERL. I recognize that the
PERL interface has not been updated due to a lack of user interest,
but I am still partial to using it if it can still be done (mostly
since I will not have to rewrite my routing path functionality).
My problem is getting the actual mapObj to construct from my
mapfile. I have not been able to get any debug information our by
checking /tmp/mserrors, which used to work nicely in such cases.
All I get is an undefined reference. My code for construction is
simple:
my $map = new mapscript::mapObj( $mapfile ) or carp "Could not
create mapscript object from mapfile: $mapfile";
in my httpd.conf I define
MS_ERRORFILE /tmp/mserrors.txt
My mapfile exists and is very simple.
I am running:
CentOS release 4.3
AMD64, dual core machine
Apache/2.0.52
mapserver-4.8.3.tar.gz
perl, v5.8.5 built for x86_64-linux-thread-multi
Thank you for your time.
