pywps on mac osx

HI

Apologize me for this mail if it is off topic here...

i'm new to python,
i've just a little experience about this wonderfull language


i'm tring to configure a python web processing server
"pywps" on my mbp

http://pywps.wald.i
ntevation.org/

it is an open project to port python environment on the web
to use it in on-line  mapping application like web-gis

i'm tring to configure it on mac osx but it don't works as
aspected,
i tried to resolve the problem with the developpers of pywps
but they  
haven't a mac machine to try it :-(

pywps is designed to use application like
R
or
GRASS
installed on a server
and use this application with local data trought the web , 
with  
local data.

to configure and try it,  a Grass installation is needed,
have any experience about?

i'v grass installed from source and i followed the
instruction to  
install pywps,
but i've an error to import the "subprocess" 
routine
(colling it from pyshall :
- import subprocess
  it works )

the error that i've is :

./wps.py
"service=WPS&version=0.4.0&request=getcapabilit
ies"
Traceback (most recent call last):
   File "./wps.py", line 74, in ?
     raise ServerError(e)
   File
"/Library/WebServer/CGI-Executables/pywps-2.0.0-rc3/pyw
ps/Wps/ 
wpsexceptions.py", line 105, in __init__
     raise NoApplicableCode(value)
pywps.Wps.wpsexceptions.NoApplicableCodePyWPS
NoApplicableCode: No  
module named subprocess
Content-type: text/xml

to configure it this is what i done :


cp /pywps-2.0.0-rc4   
/Library/WebServer/CGI-Executables/pywps-2.0.0- 
rc4/
cd /Library/WebServer/CGI-Executables/pywps-2.0.0-rc4/
python setup.py install
ln -s
/Library/WebServer/CGI-Executables/pywps-2.0.0-rc4/wps.py /

Library/WebServer/CGI-Executables/wps.py



i'm very happy if anyone mac python expert, woulėd give me
an help to  
figure out 

if you wont try it, i can post the instruction
needed to have a mac grass installation.
(it have a .app  make file to build a binary installation
to solve the grass dependancies a really nice frameworks are
avaible  
on :
http://ww
w.kyngchaos.com/software/unixport/ )


thanks for any suggestion about!

Massimo.

"No module named subprocess"
seems rather clear to me, even if that normally rises an
ImportError.

I guess you run Python 2.3?
AFAIR subprocess is a core library since 2.4, before you
could  
install it separately.

I haven't used GRASS, but Barry Rowlingson just presented at
FOSS4G about an 
integrated system called "Arlat" using Quantum GIS
(available for Mac OS X) for 
desktop mapping and R as a statistics engine, connected with
Python.

http://www.foss4g2007.org/presentations/view.php
?abstract_id=135

He is planning on posting details to the R-SIG-Geo list 
(https
://stat.ethz.ch/mailman/listinfo/r-sig-geo), but there
is a paper 
describing the implementation here:
http://www.bepress.com/cgi/viewcon
tent.cgi?article=1103&context=jhubiostat

I'm looking into this for use with MapServer:
http://mapserver.gis.um
n.edu/

William Kyngesburye has Mac OS X binaries of MapServer at
his kyngchaos site, 
although I don't recall if they use Apple's Apache 1.3 or
permit you to install 
your own Apache 2.

This doesn't solve your immediate problem, but if you want
to serve up spatial 
data via a web interface, I think you'll find MapServer much
easier to use than 
rolling your own.

building stuff on OS-X is often a bit different than other
*nix systems. 
I'd recommend that you try using these packages:

http://www
.kyngchaos.com/software/unixport

And also use the Framework Python 2.5 from:

htt
p://pythonmac.org/packages/py25-fat/index.html

That's a good source of other assorted packages that you may
need, also.

Good luck!

-Chris

Hi,

thanks for the suggestion,

already i've installed on my mac

grass, qgis, R, ossim, ossimplanet, mapserver + kamap
all works fine 
thanks to william and to all mac comunity (really great
people !)

i'll try to explain why a wps :

i need pywps beacouse my targhet is to have a web-processing
server  
(not a simple web gis)

i.e.  use the function of grass and R (installed on a
server) through  
the web, by a web-gis interface
called from a kml file  loaded into ossimplanet.

something like "embrio" or "openlayer +
pywps" :  http:// 
pywps.ominiverdi.org/

i need this solution to try the integration of ossimplanet
too

ossimplanet is able to load kml file and wms map


i done a script to produce kml , elevation-data and  wms map
 from  
grass data,

using pywps  i can integrate this  script in ossimplanet
using the  
"kml" as connection point


apologize me for my englesh and   for the bad explanation of
what i  
want try to do :-/


let me know if anyone wont help me toinstall pywps 

thanks for any suggestion!

Massimo.

You need to tell us what you've done so far, and what the
errors are. IN
any case:

1) install the Framework build of either python2.4 or 2.5
(whichever one
the pywps folks are using)

2) What python external modules does pywps require? Are they
in the
repository at pythonmac.org/packages

3) Does pywps have any compiled components? If so, try
building them
with "setup.py build". If that doesn't work, what
errors do you get?

etc....
