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 >----------<>----------<>----------<

degrees and radians.
by Jim Richardson Sept. 8, 2016

Sept. 8, 2016

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am trying to get the math module to deal with degrees rather than radians. (that it deals with radians for the angular functions like sin() isn't mentioned in the docs, which was sort of an eyeopener :) I can't find any info on doing this. I can convert from-to degrees in the code calling the function, but that's a bit clunky. Any pointers to an FM to R? :) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE804+jd90bcYOAWPYRAt9KAKCuqeC4ozuXSaKZ5xY27Wv+k04QuQCcCrCZ WyichPnKgXo+GaDdAebsaeU= =h+vc -----END PGP SIGNATURE----- -- Jim Richardson Anarchist, pagan and proud of it http://www.eskimo.com/~warlock Linux, from watches to supercomputers, for grandmas and geeks.

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.

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

New B question -- Need help with win32net.NetGroupAddUser. I used Mark Hammond sample code to create a new user from his book Python Programming on Win32. I then added one line to add the newuser to a group. def CreateUserAndShare(userName, fullName): homeDir = "%s\\%s" % (serverName, userName) # Create user data in information level 3 (PyUSER_INFO_3) format. userData = {} userData['name'] = userName userData['full_name'] = fullName userData['password'] = userName userData['flags'] = win32netcon.UF_NORMAL_ACCOUNT | win32netcon.UF_SCRIPT userData['priv'] = win32netcon.USER_PRIV_USER userData['home_dir'] = homeDir userData['home_dir_drive'] = "P:" userData['primary_group_id'] = ntsecuritycon.DOMAIN_GROUP_RID_USERS userData['password_expired'] = 1 # User must change password next logon. # Create the user win32net.NetUserAdd(serverName, 3, userData) win32net.NetGroupAddUser(serverName, "Administrator", userName) This is my error: pywintypes.api_error: (2220, 'NetGroupAddUser', 'The group name could not be found.') What should I be using for the groupname parameter, I've tried them all, Administrator, Guests, Users ext.... Any help will be greatly appreciated. Thanks, kc

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-
