I originally sent this to the MapServer mailing list, but no-one has
has responded. The references to documentation, etc. are to MapServer
docs. Perhaps someone here can help?
Thanks,
Ben

Subject: Mapscript and Python: no mapscriptc module.
I've been searching the docs and list archives, but haven't found much
on getting the Python Mapscript wrapper to work. I changed to the
mapscript/python directory, ran python, and tried to import
mapscript.py, but got the following error:
Python 1.5.2 (#1, Mar 3 2001, 01:35:43) [GCC 2.96 20000731 (Red Hat
Linux 7.1 2 on linux-i386

>>> import mapscript
Traceback (innermost last):
File "<stdin>", line 1, in ?
File "mapscript.py", line 2, in ?
import mapscriptc
ImportError: No module named mapscriptc
Here's the contents of the directory:
CVS
examples
mapscript.i
mapscript.py
mapscript.pyc
mapscript_wrap.c
As you can see, there is no mapscriptc.* . From the messages in the
list archives is appears that I need to compile mapscript_wrap.c into
mapscriptcmodule.so (since I have a mapscript_wrap.c, I'm assuming
that I don't need to run SWIG--if so I'll have to install it first).
I ran
gcc -c mapscript_wrap.c -I/usr/include/python1.5 -o mapscriptcmodule.o
without any errors. I then ran
ld -shared mapscriptcmodule.o -o mapscriptcmodule.so
also successful. However, now I get the same error as the OP:
Python 1.5.2 (#1, Mar 3 2001, 01:35:43) [GCC 2.96 20000731 (Red Hat

import mapscriptc
ImportError: ./mapscriptcmodule.so: undefined symbol: ms_error
Norman Vine responded to his post and attached a setup script to link
the module with the necessary mapscript libraries, but the list
archive software won't let me download it.
I tried
ld -o mapscriptcmodule.so mapscriptcmodule.o -shared ../../libmap.a
and it seemed to work, but now I get this error:
Python 1.5.2 (#1, Mar 3 2001, 01:35:43) [GCC 2.96 20000731 (Red Hat

import mapscriptc
ImportError: ./mapscriptcmodule.so: undefined symbol: gdImageCreate
I have a feeling this could go on for a while. As you can probably
tell, I don't know too much about building libraries. :) Can anyone
help me out? BTW, I'm using MapServer 3.5 and you can see my system
setup from the errors above.
Thanks,
Ben
