Hi There,
I am new to stackless. I am have a project for work that i wanted to
experiment with using stackless, and it requires several libraries
that are not part of the python core, including:
numpy
scipy
PIL
pyPdf
matplotlib
PythonMagick
pythonMySQL
I am building it on a VM running Ubuntu 12.04 server. I built
stackless from the v2.7 source tar.bz2 found on
http://www.stackless.com/wiki/Download. The build was successful, and
i was also successful in building/installing numpy, scipy, and PIL,
but i have gotten stuck on pyPdf. I am able to build and install it,
but when i import it in stackless python, i get:
ImportError: no module named System
with a stack trace that goes: from pdf import PdfFileReader,
PdfFileWriter --> import filters --> import System
I dont't know if this error has anything to do with Stackless but i
didnt get this installing it in regular python 2.7. Any help would be
greatly appreciated. Also, are there any known issues with using any
of the other libraries i posted above in stackless?
I had a look at the code, filters.py and saw it:
In line 44, zlib is imported, and this seems to be not built into stackless.
After installing zlib, it should work.
I found it so quickly, because there is no "System" module in cpython.
In line 52, the bad assumption is made that if zlib is not there, it must
be IronPython, which has a System module from .net .
So, that's it. Download zlib, rooted at the same level where the stackless
source was unpacked and build stackless again.
