Re: embedded python in c++ packaging
Sorry for long delay,
I've tried below code (Setting pythonpath environment variable)
and then initialize python interpreter but the embedded python interpreter
did not get the newly assigned PYTHONPATH.
I ve looked at the sys.path in python code (that is run by the embedded
interpreter) and it behaved according to older pythonpath.
Setting environment variable seemed to be correct.
Does py_initialize run in another thread so it starts before setting the
environment var?
// add custom plib.zip archive to pythonpath
if(!::getenv("PYTHONPATH"))
{
::putenv("PYTHONPATH=.;.\\plib.zip");
}
else ::putenv("PYTHONPATH=%PYTHONPATH%;.\\plib.zip");
std::cout << "PYTHONPath Set to: " << ::getenv("PYTHONPATH") << std::endl <<
"And Again: ";
system("echo %PYTHONPATH%");
Py_Initialize();
Regards,

Almost. Some imports (site, warnings, os...) are done when Py_Initialize
is executed, before there is a chance of modifying sys.path. You'll have
to modify the environment (PYTHONPATH var) or look at how py2exe does
that. Or use the name pythonXX.zip, which is already in sys.path (see PEP
273 http://www.python.org/dev/peps/pep-0273/ )

RE: embedded python in c++ packaging
I've done this the rather old-fashioned way.
Basically, what I do is:
Step 1:
Embed Python:
if(!::getenv("PYTHONHOME"))
{
::putenv("PYTHONHOME=");
}
if(!::getenv("PYTHONPATH"))
{
::putenv("PYTHONPATH=.");
}
Py_SetProgramName("leaktester");
Py_InitializeEx(0);
init_memoryhoginterface(); // This initializes your SWIG module
PyRun_SimpleString("print 'HELLO FROM PYTHON'"); //<--- OR you can do
something else here like run a file
Step 2:
Extend python to talk back to your C++ code.
I use one giant SWIG module (see init function above)
SWIG allows you to finely control what you expose to python, so you don't wind
up exposing the whole C++ API.

Using py2exe has an additional advantage, it recursively scans all
modules
looking for dependencies.
Once you know the required set of modules, you can bundle them in a .zip
file and add its full path into sys.path (the absolute path including
filename and .zip extension). Python does look into the .zip searching
for
modules.

Re: embedded python in c++ packaging
The Python byte-code files are already pretty dense, so compressing them further is unlikely to work if you try to put them in a zip.

embedded python in c++ packaging
Hello, I have been developing an application in C++ that embeds Python interpreter. It takes advantage of too many modules from Python. When I want to package this application, I need to add too many files (.pyc) from Python/lib folder together with Python25.dll. Is there a way to pack these .pyc files to a zip file and redirect Python25.dll to that zip file? Thanks in advance. -- Furkan Kuru -- http://mail.python.org/mailman/listinfo/python-list
