I've fixed the problem, here's my solution in case anyone else needs it: The problem didn't have to do with the Platform SDK in the end. The configuration that I'm using is MSVC6 SP3 on Windows 2000. The fix was to add : flags msvc-stlport DEFINES : _NTOS_=1 ; to the "special flags for STLport 4.0" block in tools\build\msvc-stlport-tools.jam (line 117, for example). I have a question for jam experts: How can I set this define (_NTOS_=1) from the command line?

Exposing static members using boost.python
by sashan 06 Sep '02

06 Sep '02

Hi Is the correct way to expose static members by writing a wrapper function for them? For example void wrap_fn() { Class::fn(); } . . . this_module.def(wrap_fn, "fn"); Thanks in advance Sashan

array.hpp problem with msvc7 and stlport
by li_lirong 06 Sep '02

06 Sep '02

I got many errors with boost\array.hpp after I chaged to use stlport instead of the one from msvc7. one of these errors is: d:\cpplibs\boost\boost\array.hpp(61) : error C2039: '_Ptrit' : is not a member of '_STL' I have tried to config stlport with STLP_NO_OWN_NAMESPACE and _STLP_DONT_RENAME_STD but the errors still exist. Is it a bug in array.hpp or stlport? Regards, Lirong

ref. to object functions from threads
by Luis De la Parra 06 Sep '02

06 Sep '02

hi all, is there a way to get a reference to the function object used by a boost::thread object?? when you create a new thread and feed it a function object it copies it and then starts a new thread of execution on this object.. well, I would like to send messages to the object in which the thread is running but I don't know how to do it with boos.threads... is there a way to tell boost:thread not to copy the function object but to use it directly?, or to ask the thread object to give a reference to the object? I am now doing a dirty hack which consists of the object putting itself (a pointer) in a static chained list during construction and remove itself in the destructor, this way I can call a static member function which returns this list to get a hold of the object. There is also a static mutex protecting this list to make sure no other objects are created / destructed while one of them is inserting or removing itself from the list. it is working, but I don't think this is a very "clean" approach.. does anyone have any ideas how it could be done better?? thank you. regards, luis.

n-ary ordered tree template in boost ??
by Marc Cromme 06 Sep '02

06 Sep '02

Dear Boost Members I was wondering if there is an n-ary ordered tree template in boost, something like template <size_t N, class Type, class Alloc = allocator<Type > > class NTree which is a standard container, and a reversible container, ordered by level. That is, first element is root, next series of elements are childs of roots, next series are grandchilds of root , and so on. This way one could parse level by level like a reversible container. There should be the obvious member functions for inserting/deleting child nodes and subtrees. As far as I can see, there is not such a template in boost, but the question is then: 1) can it be emulated using the grah library ?? or 2) is there already an proposal/prototype for such a thing ?? or 3) would it be interesting to include such a thing in boost ?? your's sincierely, Marc Cromme

[BGL] 2D/3D layout algorithms
by Andrew Cunningham 06 Sep '02

Has anyone adapted any 2D and/or 3D graph layout algorithms to work with Boost ( i.e. minimum crossing etc...). Seems an obvious question, but I did not find anything via searching... Andrew

Newbie boost::mem_fn problem
by Mark Snelling 05 Sep '02

05 Sep '02

Hello, My problem I think is very simple, I just can't seem to find the solution I have an STL list of object pointers and I want to call a member function on each of the pointers in the list usigng the STL for_each algorithm. This would seem easy if the list contained the actual objects rather than pointers to them, but because they are pointers I can't find a way of doing this. class Block { public: void update(int x); }; void main() { list<Block*> blocks; for_each(blocks.begin(), blocks.end(), *****); // Call update on each item in list } what should I replace the ***** with? Any help appreciated! Mark.

Is it possible to retrieve blank strings with boost::tokenizer?
by Sean Shubin 05 Sep '02

05 Sep '02

For example, using the code: string line = "\taaa\t\tbbb\t"; typedef tokenizer<char_separator<char> > tok; char_separator<char> sep("\t"); tok tokens(line, sep); for(tok::iterator i = tokens.begin();i!=tokens.end();++i) { cout << "\t\"" << *i << "\"" << endl; } I get this output: "aaa" "bbb" I want to get this output: "" "aaa" "" "bbb" ""
