Re: Embedded Boost.Python Enum
On 10/18/07, Cory [EMAIL PROTECTED] wrote:
Hi,
I have a hopefully quick question about how to use Boost.Python to
export an Enum.
I am embedding python in C++ and am currently exporting my classes in
the following way:
nameSpace[OBJECT] = class_OBJECT(OBJECT)
.def(getType, OBJECT::getType)
.def(setSprite, OBJECT::setSprite);
So following this, I assumed that when exporting an enum the following
should work:
nameSpace[OBJECT_TYPE] = enum_OBJECT_TYPE(OBJECT_TYPE)
.value(GENERIC_OBJECT,GENERIC_OBJECT)
.value(MAP_OBJECT,MAP_OBJECT)
.value(TOTAL_OBJECT_TYPES,TOTAL_OBJECT_TYPES)
.export_values();
while the above compiles, it causes the following run time exception:
AttributeError: 'NoneType' object has no attribute 'OBJECT_TYPE'
I took a look at the documentation and the only explanation I found
for enum appeared to be for extending python with modules. using the
following form:
BOOST_PYTHON_MODULE(enums)
{
enum_color(color)
.value(red, red)
.value(green, green)
.export_values()
.value(blue, blue)
;
}
I think you should read next documentation:
http://boost.org/libs/python/doc/v2/scope.html
I COULD do the above, I would prefer the first method if possible. I
however do not know how to import the module if it is statically
linked because doing a simple import does not work and I am not
familiar enough with the boost.python library, Python C API, or Python
itself to know how to set it up. So My question is this:
How can I either make the first method of adding an enum work and not
throw the exception, OR once I create the BOOST_PYTHON_MODULE in an
embedded python c++ program how to I then import that module into my
embedded python?

You can define function that first argument is a reference to the instance

Then you can register it as usual function.

Few comments:
1. It is better to ask Boost.Python related questions on its mailing list:
http://mail.python.org/mailman/listinfo/c++-sig/
2. If you just start with Boost.Python, try Py++
( http://language-binding.net/pyplusplus/pyplusplus.html )
Boost.Pythoncode generator
It has nice GUI ( no need to learn any API ):

[ANN]Py++-0.8.2
I'm glad to announce the new version of Py++. Download page: http://language-binding.net/pyplusplus/download.html What is it? Py++ is an object-oriented framework for creating a code generator for Boost.Python library. Project home page: http://language-binding.net/pyplusplus/pyplusplus.html The new version introduces quite few improvements: * performance, in some case x10 * fully automatic algorithm for exposing C++ get\set functions as Python properties. * treatment for previously generated, but no more in use, source files * convenience API for translating user defined exception to Python one * generated code - improved formatting * better understanding of call policies: - default_call_policies should not be generated any more - return_value_policy return_opaque_pointer , Py++ will create specialization for type_id function, as required by the library * documentation, new chapters were written, all source code in documentation is highlighted using pykleur package.

Boost.Python is the only tool that provides complete functionality( extending and embedding ). Also I think cgkit is dealing with the problem too. But for this to work, the python code needs to know the Player class, is it right? Right. Does that mean I need to build a python wrapper class for Player and import Player in the python code? But because this application is built on top of a game engine, Player class inherits many classes from there, I cannot possibly wrapping them all, right? It depends on how much functionality you want to export. Also, some global objects are probably needed in this code of adding players, how can the python code access them? Boost.Python provides the functionality you need. Btw, if you can point me to any source code of non-trivial projects utilizing SWIG/Boost.Python, that would be very helpful.

Looks like it's glibc linker inflexibility: http://hathawaymix.org/Weblog/2004-12-30 There is no provision for modifying the library search path once your program has started. Thanks, well small script around my program will make the trick. I think I have no other choise. Python does update enviromental variables if you change os.environ or call os.putenv, but the linker ignores the changes.

Re: LD_LIBRARY_PATH - how to set?
Thanks for help. But it is not exactly solution I am looking for. I would like to do it from python script. For example update_env() #- this function will change LD_LIBRARY_PATH import extension_that_depends_on_shared_library Roman On Mar 31, 2005 9:35 AM, John Abel [EMAIL PROTECTED] wrote: With Solaris 8+ you would use the command crle, with Linux (RedHat/SuSE/Mandrake) you need to add the relevant directories /etc/ld.so.conf and run ldconfig. I've not got a Debian box to hand, so I can't say if it matches, but that should give you a pointer. I think I should have permissions to do it. (more over users of my scripts should have permissions ) HTH J Roman Yakovenko wrote: On Mar 31, 2005 9:20 AM, John Abel [EMAIL PROTECTED] wrote: What OS? Linux? Solaris? Does it matter?

I need to load extension module that depends on shared library. Before actually importing module I tried to edit os.environ or to call directly to os.putenv without any success - shared library was not found. I tried to search the Internet for the answer. The only approach I saw was to set LD_LIBRARY_PATH before invoking python script. I don't like this solution.
