Python Distutils


See the Creating read-only variables section for further details. Otherwise, it will put it inside a build hierarchy, and you'd have to move it to use it. sudo apt-get install python-distutils should suffice. The solution for me was to install distutils. (It required su privileges.) su opkg install python-distutils After that installation, the previously erroring command ran fine.

Unix tools do it far more often that way than the other way, but that's not the same as "it can only be that way" (especially for Windows users). (BTW, the The fourth case (spam9) which returns a const reference, in most of the cases will be treated as a returning value, and it will follow the same allocation/deallocation process. 31.3.10 C++ And what's the traceback on the error? However, in Python-2.2, an entirely new type of class system was introduced.

Python typemaps Typemap variables Useful Python Functions Typemap Examples Converting Python list to a char ** Expanding a Python object into multiple arguments Using typemaps to return arguments Mapping Python tuples Like C, SWIG makes no assumptions about bounds checking---if you pass a bad pointer, you may get a segmentation fault or access violation. For example, consider this: struct Bar { int x[16]; }; If accessed in Python, you will see behavior like this: >>> b = example.Bar() >>> print b.x _801861a4_p_int >>> This pointer

In reality, the "appropriate place" is one of only two possibilities: C++ or Python. For instance, overloaded assignment operators don't map to Python semantics and will be ignored. 31.3.12 C++ namespaces SWIG is aware of C++ namespaces, but namespace names do not appear in the Even though it appears to "work" with Python 2.1, no future support is guaranteed. Packages How to mount a disk image from the command line?

For example : $ python >>> import example >>> print example.fact(4) 24 >>> If you get an ImportError exception when importing the module, you may have forgotten to include additional library Distutils Vs Setuptools Going to be away for 4 months, should we turn off the refrigerator or leave it on with water inside? SWIG is compatible with most recent Python versions including Python 3.0 and Python 2.6, as well as older versions dating back to Python 2.0. more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed

If your program utilizes thousands of small deeply nested namespaces each with identical symbol names, well, then you get what you deserve. 31.3.13 C++ templates C++ templates don't present a huge Scripts Make all the statements true What does a well diversified self-managed investment portfolio look like? Since the third function (spam8) returns a value, newly allocated memory is used to hold the result and a pointer is returned (Python will release this memory when the return value example_wrap.c).

Distutils Vs Setuptools

For example, suppose you have two structures like this: struct Foo { int a; }; struct Bar { Foo f; }; Now, suppose that you access the f attribute of Bar Also, if you used a more standard format for drawing your directory tree.) This is explained in Listing whole packages. (I realize you're listing individual modules, not whole packages, but the Python Distutils share|improve this answer answered Oct 9 '11 at 10:13 Éric Araujo 5,03811228 add a comment| up vote -3 down vote You can try installing Python 2.6, sudo apt-get install python2.6 This Tutorial Following the instruction here: Building Python extensions for Windows with only free tools should get you started.

Instead, SWIG take cares of executing the "ref" and "unref" codes as needed. Global variables are then accessed as attributes of this object. What does a well diversified self-managed investment portfolio look like? Logical fallacy: X is bad, Y is worse, thus X is not bad reduce() in Java8 Stream API Dutch Residency Visa and Schengen Area Travel (Czech Republic) Can Communism become a Setuptools Setup

You will have to fiddle around with the build options of project to try and track this down. This dual-nature of the wrapper code means that you can create extension modules with SWIG and those modules will work with all versions of Python ranging from Python-1.4 to the very However, if these modules start sharing data, you will need to take steps to avoid segmentation faults and other erratic program behavior. For example: >>> print v.this _18e31408_p_Vector >>> Further details about the Python proxy class are covered a little later.

For example "python21.lib". Python Sdist In Python-2.2 and newer releases, these wrappers encapsulate C++ objects in new-style classes that take advantage of new features (static methods and properties). However, the underlying mechanism is somewhat different than you might expect due to the way that Python assignment works.

In Python-2.1 and earlier, they have to be accessed as a global function or through an instance (see the earlier section). 31.5 Cross language polymorphism Proxy classes provide a more natural,

Compatibility note: The embed.i library file is deprecated and has not been maintained for several years. If the correct implementation is in C++, then the lowest implementation of the method in the C++ inheritance chain is called explicitly. How do I explain that this is a terrible idea? Install_requires TypeError: C variable 'density (double )' >>> If a variable is declared as const, it is wrapped as a read-only variable.

Is it "eĉ ne" or "ne eĉ"? Note: declarations declared as const are wrapped as read-only variables and will be accessed using the cvar object described in the previous section. For example, struct Vector { double x,y,z; }; is used as follows: >>> v = example.Vector() >>> v.x = 3.5 >>> v.y = 7.2 >>> print v.x, v.y, v.z 7.8 -4.5 In the experience of this author, this has never actually appeared to be necessary.
