SWIG+Distutils - no harmony?
by m.bless＠gmx.de July 7, 2018

July 7, 2018

Getting courageous I try building 'example.pyd' from the SWIG 'Simple Example' using SWIG and the Distutils. Looks promising but doesn't succeed. I didn't modify 'example.c' and 'example.i'. Problems/questions: (1) Is 'setup.py' ok? (2) BEWARE: What's really shocking: After see (unsuccessful) python setup.py build -cmingw32 the original 'example.c' is GONE AND AWAY - replaced by the wrapper. (3) What's going wrong? Martin Sources und logs following: >----------<>----------<>----------< # setup.py # mb: Is this ok? import distutils from distutils.core import setup, Extension #from distutils.extension import Extension setup(name = "Example 'Simple' from the SWIG examples", version = "2.2", ext_modules = [Extension("example", ["example.i"])]) >----------<>----------<>----------< /* File : example.i */ %module example extern int gcd(int x, int y); extern double Foo; >----------<>----------<>----------< /* File : example.c */ /* A global variable */ double Foo = 3.0; /* Compute the greatest common divisor of positive integers */ int gcd(int x, int y) { int g; g = y; while (x > 0) { g = x; x = y % x; y = g; } return g; } >----------<>----------<>----------< C:\python Python 2.2 (#28, Dec 21 2001, 12:21:22) [MSC 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> >----------<>----------<>----------< swig -version SWIG Version 1.3.10u-20011211-2004 Copyright (c) 1995-1998 University of Utah and the Regents of the University of California Copyright (c) 1998-2001 University of Chicago Compiled with CC >----------<>----------<>----------< >python setup.py build -cmingw32 running build running build_ext building 'example' extension swigging example.i to example.c c:\pyext\swig\swig.exe -python -dnone -ISWIG -o example.c example.i c:\mingw\bin\gcc.exe -mno-cygwin -mdll -O -Wall -IC:\PYTHON22\include -c example.c -o build\temp.win32-2.2\Release\example.o writing build\temp.win32-2.2\Release\example.def c:\mingw\bin\gcc.exe -mno-cygwin -mdll -static -s build\temp.win32-2.2\Release\example.o build\temp.win32-2.2\Release\example.def -LC:\PYTHON22\libs -lpython22 -o build\lib.win32-2.2\example.pyd swig: Warning. -dnone option deprecated. example.c: In function `SWIG_UnpackData': example.c:363: warning: `uu' might be used uninitialized in this function example.c: In function `SWIG_ConvertPtr': example.c:429: warning: suggest explicit braces to avoid ambiguous `else' example.c:432: warning: suggest explicit braces to avoid ambiguous `else' example.c:438: warning: suggest explicit braces to avoid ambiguous `else' example.c: At top level: example.c:154: warning: `SWIG_TypeQuery' defined but not used example.c:385: warning: `SWIG_ConvertPtr' defined but not used example.c:468: warning: `SWIG_ConvertPacked' defined but not used example.c:537: warning: `SWIG_MakeShadow' defined but not used build\temp.win32-2.2\Release\example.o(.text+0xbda):example.c: undefined reference to `gcd' build\temp.win32-2.2\Release\example.o(.text+0xc35):example.c: undefined reference to `Foo' build\temp.win32-2.2\Release\example.o(.text+0xc6b):example.c: undefined reference to `Foo' build\temp.win32-2.2\Release\example.o(.text+0xc71):example.c: undefined reference to `Foo' error: command 'gcc' failed with exit status 1 >----------<>----------<>----------<

Einstein's Riddle
by Steve Graham Sept. 17, 2015

Sept. 17, 2015

Who would be interested in using his/her brain (and his computer) to solve the following? Steve Graham === Einstein's Riddle Albert Einstein wrote this riddle this century [ed. 20th century]. He said 98% of the world could not solve it. There are 5 houses in 5 different colors. In each house lives a person with a different nationality. The 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar or drink the same beverage. The question is: "Who owns the fish?" Hints: The Brit lives in the red house. The Sweed keeps dogs as pets. The Dane drinks tea. The green house is on the left of the white house. The green house's owner drinks coffee. The person who smokes Pall Mall rears birds. The owner of the yellow house smokes Dunhill. The man living in the center house drinks milk. The Norwegian lives in the first house. The man who smokes Blends lives next to the one who keeps cats. The man who keeps the horse lives next to the man who smokes Dunhill. The owner who smokes Bluemasters drinks beer. The German smokes Prince. The Norwegian lives next to the blue house. The man who smokes Blends has a neighbor who drinks water.

Python to C++ in a pickle
by Larry Whitley April 2, 2015

April 2, 2015

I'd like to pickle an object in python and unpickle it in C++. The object in question is a python dictionary so it will have to go into a C++ map. Has someone done this and is willing to share? Or, is the cPickle source available on the web somewhere? Larry

Python OPC -wrapper for data collection, anyone seen it ?
by pekka niiranen March 24, 2014

March 24, 2014

Has anybody seen OPC -wrapper done in python ? In industry OPC -servers are breaking thru. It is a microsoft based technoloqy to gather process information. Many Control System manufacturers have their own OPC -servers. There exists a visual basic wrapper -library so that one write VB - programs to enquire data from OPC -server.Wrapper done to python would be cool. Mark Hammond was not interested, but I am not giving up yet... -pekka-

mutlifile inheritance problem
by maurelius01＠hotmail.com Sept. 21, 2013

Sept. 21, 2013

I have classes defined in different files and would like to inherit from a class in file A.py for a class in file B.py but am running into problems. I'm using Python 1.5.2 on Windows NT Here's a specific example: ************************ file cbase01.py: class CBase: def __init__(self): self.cclass = None print "cbase" class CImStream(CBase): def __init(self): CBase.__init__(self) print "CImStream" ************************* in file wrappers_A01.py: import cbase01 reload(cbase01) class ImStream_SavedBitmaps(cbase01.CImStream): def __init__(self): cbase.CImStream.__init__(self) print "SavedBitmaps" ************************** in file sequencer01.py import cbase01 # the offending lines, program works reload(cbase01) # if I comment these out. class Sequencer: def Append(self, item): pass ***************************** in test02.py import wrappers_A01 reload(wrappers_A01) import sequencer01 reload(sequencer01) x0 = wrappers_A01.ImStream_SavedBitmaps() *************************************************************** If I run test02 I get the traceback Traceback (innermost last): File "<string>", line 1, in ? File "D:\PythonCode\pna\eyeTracking\tests\test02.py", line 15, in ? x0 = wrappers_A01.ImStream_SavedBitmaps() File "D:\PythonCode\pna\eyeTracking\tests\wrappers_A01.py", line 21, in __init__ cbase.CImStream.__init__(self) TypeError: unbound method must be called with class instance 1st argument Any ideas what I am doing wrong? Thanks, Marc

AIX installation can't find zlib
by Larry Whitley Nov. 3, 2011

Nov. 3, 2011

I've just installed the 1.5.2 source distribution on an AIX system and when I say "import zlib" it responds: >>> import zlib Traceback (innermost last): File "<stdin>", line 1, in ? ImportError: No module named zlib >>> I'm not sure where zlib is supposed to be. It's not in the Lib subdirectory of Python-1.5.2. In the Modules subdirectory I find zlibmodule.c. Nothing germaine in the Objects subdirectory. Looked at config.log and config.status, no mention of zlib. Looking at the sys.path I see: .../ldw/Python-1.5.2> python Python 1.5.2 (#1, Jul 26 2000, 14:21:56) [C] on aix4 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam >>> import sys >>> sys.path ['', '/.../rchland.ibm.com/fs/u1/ldw/Projects/Programs/wtCache', '/.../rchland.ibm.com/fs/u1/ldw/Python-1.5.2/Lib/', '/.../rchland.ibm.com/fs/u1/ldw/Python-1.5.2/Lib/plat-aix4', '/.../rchland.ibm.com/fs/u1/ldw/Python-1.5.2/Lib/lib-tk', '/.../rchland.ibm.com/fs/u1/ldw/Python-1.5.2/Modules'] >>> Any suggestions?
