Installation using distutils

Windows Installation and Demo

  1. Fetch
  2. Expand the archive into a directory of your choosing C:\ for example.
  3. Install the PyCXX files:
    1. C:> cd \pycxx-7.0.0
    2. C:\pycxx-7.0.0> python install
  4. Build and run the demo extensions:
    1. C:> cd \pycxx-7.0.0
    2. C:\pycxx-7.0.0> python win32 win32.mak 
    3. C:\pycxx-7.0.0> nmake -f win32.mak clean test

Unix Installation and Demo

  1. Fetch
  2. Login as root. root access is typically needed on Unix systems to install the PyCXX files into the Python directories.
  3. Expand the archive into a directory of your choosing ~\ for example.
  4. Install the PyCXX files:
    1. # cd ~/pycxx-7.0.0
    2. # python install
  5. Build and run the demo extensions:
    1. # cd ~/pycxx-7.0.0
    2. # python linux linux.mak
    3. # make -f linux.mak clean test

Revision History

Version 7.0.0 (15-Aug-2016)

Warning: This version fixes a number of problems that require source incompatible changes.

However by defining PYCXX_6_2_COMPATIBILITY the V6.2.x API is restored. This is not recommended for new code.

The first version of python3 that is supported is 3.3.

A special thanks goes to Benjamin Webb, working at the US Army Engineer Research and Development Center, who has contributed to the design and testing of this release. 7.0.0 is better for his work.

New source file needs to built: Src/cxx_exceptions.cxx. This file implements the new exception handling features.

Fix the type used for lengths and sequence indexes to use Py_ssize_t. This will require sources changes for users of PyCXX.

Implement smart handling of Exceptions between C++ and Python. You can now catch exceptions in C++ by type that are raised in C++ or Python.

All builtin exceptions are support and are user defined exceptions.

The base exception type is now BaseException not Exception. To upgrade source code replace all use of Exception with BaseException.

The documentation has been updated to describe the new exception features.

The supportSequence, supportMapping, supportNumber etc functions now take a bit mask that defines which specific callbacks are handled.

Version 6.2.8 (10-May-2016)

Fix crash when a member function is called via callMemberFunction() and that function raises an expection.

Found in comment on StackOverFlow. Fix memory size allocated for new objects. It used the wrong size calculation, but was big enough to avoid problems.

Version 6.2.7 (28-Apr-2016)

Fix missing ptr__Unicode_Type.

Fixes from make python2 also remember the m_module and add accessor functions.

Fix for indirection issues from Vivian De Smedt.

Update to work with latest Microsoft Visual C++ for python 2.7. All test run in Win32 and Win64.

PyCXX.html documention has been updated, especially with 2TO3 information.

Use delete[] for objects allocated with new[].

Version 6.2.6 (04-Jan-2015)

Fix build issue with GCC 4.2.1 on FreeBSD and Mac OS X (stop python defining isspace as a macro).

Remove support for python 3.1 (API's are unstable).

Add Python 3.3 support.

Patch from Michael Droettboom to fix compilation issues.

Patch from Michael Droettboom to add buffer interface for python3.

Version 6.2.4 (3-Mar-2012)

Fix memory leak in string encode and decode functions

Fix indirect python loading on windows - Bool_type was missing

Version 6.2.3 (11-Mar-2011)

Version 6.2.2 (26-Dec-2010)

Fix problem compiling against Python 3.1.3

Version 6.2.1 (3-May-2010)

Fix problems with new style classes

Replace all example makefile and project files with script.

Add APIs to make calling python functions easier. See TupleN(), callOnSelf(), self()

Version 6.1.1 (26-Sep-2009)

Supports Python 3 starting at Python 3.1 and Python 2

Code clean up to fix compiler warnings reported by gcc 4.2.1 on Mac OS X when building for Python 3.

Version 6.1.0 (19-Jul-2009)

Support Python 3 and Python 2
