boost python and smart pointers
by Martin Strubel 01 Feb '02

01 Feb '02

Hello, I've lately experimented with Boost.Python and found it pretty useful. Though I've run into one thing which I couldn't figure out by the documentation, I hope someone can give me a hint there: I have a function returning a pointer to an 'owned' structure, i.e. its container takes care of creation and deletion. In Python, I want to wrap this pointer into a direct reference to the struct, i.e. no copying. To guard the access and make sure the object can't be accessed after the deletion, I want to wrap the smart pointer AS a python object. for example, a C++ function returning an 'owned' face from a mesh: FaceSmartPtr Mesh::addFace() { .. } should be wrapped for access in Python like: f = mesh.addFace() with subsequent calls for face manipulation like: f.addVertex((0.0, 0.0, 0.0)) where this should again call something like if (f_sptr.isValid()) f_sptr->addVertex(...); else throw_pyException_ptrInvalid(); Does Boost support this automatically ? Or do I have to wrap all these functions myself ?

RE: [Boost-Users] Suggestion -- Boost Building

In my case (the most recent how-can-I-build-this question) I'm trying (unsuccessfully) to use the regex library, which requires compiling.... I used to be able to build this, but since the boost.build stuff came along, I've been completely unable to build anything at all. The documentation is worse than useless because it's so self-contradictory.... -------------------------- John Wismar mailto:jwismar@alldata.com > -----Original Message----- > From: Duane Murphy [mailto:duanemurphy@mac.com] > Sent: Saturday, January 26, 2002 12:15 AM > To: Boost Users > Subject: [Boost-Users] Suggestion -- Boost Building > > > It seems a lot of questions come up on the list about > "building" the boost libraries. > > I wonder how many of these people realize that most of the > functionality of the Boost "libraries" is completely > encapsulated in the header files?

Cannot find regular expression symbols in Solaris debug
by phlasnicek 31 Jan '02

31 Jan '02

Hi, I am using Solaris Workshop 5.0 and I am using boost libraries for regular expressions. Everything builds fine and runs ok except when I try to attach to the process and run the debugger. I get the following error: warning: cannot demangle '__1c9uX__unnamed_6ofsRKVdR8zYNQre_get_error_str6FI_pkc_' Anyone have any suggestions, I would appreciate it very much. Thanks Paul

RE: [Boost-Users] Re: boost::pool + shared memory
by Tom Matelich 30 Jan '02

I've been using the ACE_Malloc framework from ACE (http://cs.wustl.edu/~schmidt/ACE.html) to solve a similar problem (sharing statics between DLL's). It takes a little while to figure out because the documentation is a little slim, but once you do it pays off pretty quickly. Doxygen documentation for ACE_Malloc is at: http://doc.ece.uci.edu/Doxygen/Current/html/ace/classACE__Malloc__T.html and the shared_mem memory pool is at: http://doc.ece.uci.edu/Doxygen/Current/html/ace/classACE__Shared__Memory__Po ol.html I ended up not having to write an STL allocator using ACE_Malloc, but I don't think it would be too difficult. If you get it right, a lot of ACE users would be your friend :) Tom Matelich > -----Original Message----- > From: xpav_2000 [mailto:alex@pavloff.net] > Sent: Tuesday, January 29, 2002 6:01 PM > To: Boost-Users(a)yahoogroups.com > Subject: [Boost-Users] Re: boost::pool + shared memory > > > --- In Boost-Users@y..., Tom Matelich <tmatelich@z...> wrote: > > Looks like pool may not be what I need, darn.

Hi John, that's what I'm doing now. I just want to fully understand the new jam way of building/using boost, and eg to see what is neccessary to use the 'new way'. Will the 'old way' be deprecated someday? Does/will the new way support static libs? > >And how to link the boost thread stuff? > >Is it supported for statically linked apps at all? > Build threadmon.cpp into a dll, and the rest of the source into a static > lib with the options you want. Okay, thanks, I will try this combination. bye, Bruno
