Will libraries built on WinNT run on Win98? (MinGW)
by Reed Hedges 31 Mar '05

31 Mar '05

I know that Win98 is not really supported, but is there any chance that libraries (specifically thread and regex) that were build on WinNT using MinGW work on Win98 (in MinGW)? My guess is no, but has anyone tried it? thanks reed

Bug in lexical_cast<> with doubles
by Leon Raj 29 Jan '05

29 Jan '05

I think I've found a bug in the boost::lexical_cast<> library (v1.31.0) on WinXP SP1, MSVC 6.0 (sp5) and MSVC.NET 2003. --- Start code snippet --- #include <boost/lexical_cast.hpp> #include <iostream> int main( int argc, char* argv[] ) { double dMax = = std::numeric_limits< double >::max(); // On a Win32 x86 system, dMax is now 1.7976931348623157e+308 // This is successful and strMax is "1.797693134862316e+308" std::string strMax = boost::lexical_cast< std::string >( dMax ); try { double newDMax = boost::lexical_cast< double >( strMax ); std::cout << "Successfuly" << std::endl; } catch ( boost::bad_lexical_cast& ) { std::cout << "Failed to cast" << std::endl; } // On a Win32 x86 system, this always fails, // because (I think) strMax overflows a double, // because 1.7976931348623157e+308 is *rounded UP* // to 1.797693134862316e+308, which cannot be // represented by a double } --- End code snippet --- ----------------------------------------------------- Leon Raj Senior Engineer Invetech Pty.

Format Library - Asterisk Support
by Barak Simon 01 Dec '04

01 Dec '04

Hi, I have noticed that the format library does not support at present the printf asterisk for providing dynamic width as an extra parameter. Unfortunately my users need to use this widely and I would really hate to revert back to a non-typesafe solution. a. Are there any plans to support it in near future? b. If not, is there an easy way to add that to parsing.hpp, parse_printf_directive method, parse_width & parse_precision sections? currently the asterisk is ignored, and the library throws an exception thinking it has an extra parameter. c. Is there any workaround I miss which may give me the same expected result of providing say "%*s, width, charPtr" ? (I have 'width' and a non-null-terminated char pointer and need to construct the correct string from them without doing unnecessary copying...)

MPL Library
by Edward Diener 18 Nov '04

18 Nov '04

I have bit the bullet and am attempting to get my head around the MPL library. I realize there is a book out by Messieurs Abrahams and Gurtovoy, I believe, but I thought I would tackle the boost documentation first. A few questions: 1) Is the documentation up to date ? 2) There are three separate documents to study, it seems, all giving information about the MPL library, a white paper circa 2002, a reference, and a mini-tutorial. Is the information in these in sync with each other ? The reason I ask is that the white paper/mini-tutorial mentions if_<> and apply_if<> but the reference does not mention them at all.Are they just understood intrinsic metafunctions that need no reference, or what ? If the former, are there more of these intrinsic metafunctions and, if co, what are they and what do they do ? 3) A number of the topics in the reference documentation mentioned in generalized overviews of the various sections have no specific links. Does this mean that they were never implemented ? Seems dubious in a number of cases. I would seriously like to figure out how MPL works and play around with it, but I feel stymied with what is in the boost docs.

Boost::Regex - bug work-around...?
by Michael Starling 02 Nov '04

02 Nov '04

Hi there... I've been trying to implement some routines using the Boost library, primarily with the excellent RegEx library. Everything was working well enough in small tests, but when I tried running the routines on many patterns, my program would crash (it performs various pattern matching and search-and-replaces in multiple text files). I was able to determine that the crashes came on the calls to regex-related functions (though it tended to be a little unpredictable as to when, depending on the set of files I gave it). I tried changing my project settings (I use VC6, btw) to link with "debug" libraries instead of the standard ones (eg. "Debug Multithreaded"), and ran the program again, and everything worked perfectly. Unfortunately... I don't want to have my program running with all-debug libraries for performance and size reasons. However, is it possible to have my link-settings set to use standard libraries as before, but for the stuff that uses the regex library, to use a debug ".lib" file? Or... in the 'bjam' process, is it possible to say something to the effect of "when compiling the regex libraries, turn off compiler optimizations", so I can get a standard library that should work...? Hopefully that'll make sense... :P Thanks for your time, Mike.

uBLAS past, present, and future.
by Daniel L Elliott 02 Nov '04

02 Nov '04

Hello, I am trying to better understand the current status of the uBLAS library. Below I have listed a few questions. Of course, any responses are completely off the record. We just need to get a better idea of the current state of uBLAS. Thank you, in advance, for any information you provide. - What is the history of uBLAS? What is the eventual goal? - What is the current status of uBLAS? How complete is it currently? Anything left unimplemented (Sparse stuff)? Should a project which relies upon uBLAS heavily *expect* to encounter bugs within uBLAS? - Is uBLAS expected to become a part of the C++ standard? - What advantages/disadvantages do you feel uBLAS has when compared to FORTRAN. Could it replace FORTRAN? Thank you to everyone for your time and effort on all BOOST libraries and for your answers. Sincerely, Dan Elliott

I can do: class_<mine, boost::shared_ptr<mine>, bases<parent> , boost::noncopyable>("mine", no_init) However, this class has virtual functions. And while not strictly required, I tried to follow the recommendation that you create wrappers for all the functions, so that you can sub-class the C++ object in python. So I already have a class of: class mine_w : public mine { public: PyObject *self; mine_w(PyObject *_self) : self(_self) {} virtual bool func1(int a) { return call_method<bool>("func1", a); } } So right now, by definition looks like: class_<mine, mine_w, boost::noncopyable>("mine", no_init); If I changing mine_w to shared_ptr<mine> allows it to work. But trying to do: class_<mine, boost::shared_ptr<mine_w>, bases<parent> , boost::noncopyable>("mine", no_init); Again complains about no to-python converter for the given type. And trying to supply both, with: class_<mine, boost::shared_ptr<mine>, mine_w, bases<parent> , boost::noncopyable>("mine", no_init); Complains that I have too many template arguments. Also, what about the (hypothetical) situation where I might return shared_ptr<mine> from one function, but auto_ptr<mine> from another? Also, another "bug". If I create a pure-virtual class, then I should set the no_init field. However, if I try to sub-class this object in Python, the C++ constructor cannot be called, and so I can't pass this object to C++ functions. I'm trying to create some opaque interface classes (callbacks, etc). Without a wrapping class, it won't compile without no_init, since it tries to compile a function that would generate one. With a wrapping class I don't need no_init, and if I put it, then I can't properly subclass my object. Are these just known problems, and people live with it, or has it just not really come up?

shared_ptr<> w/ Boost::Python
by John Meinel 30 Oct '04

30 Oct '04

I realize this may not be the right list, but since I'm already subscribed... I've been using boost::python to wrap some C++ code for quite a while now, and I've been quite happy with it. However, I decided to get into boost more, and I've found that shared_ptr/shared_array are quite nice. So I've started changing my functions from returning a raw pointer to returning a shared_ptr. In the boost::python tutorial, they talk about when you return a raw reference or pointer, you need to wrap it to manage lifetime of the object. http://www.boost.org/libs/python/doc/tutorial/doc/call_policies.html In the beginning of that page, they talk about how smart pointers are better for defining the scope and lifetime of objects, but sometimes raw pointers are necessary. I've gotten pretty good about when to manage_new_object, or return_internal_reference, etc. However, now that I have changed my return functions to actually return a smart pointer, it doesn't seem like I should need to wrap the return value anymore. Only now, when I try to do a "get" it gives me the error: " No to_python (by-value) converter found for C++ type: class boost::shared_ptr<class mine> " I have a converter for "class mine". I actually thought that the lifetime managers were using a shared_ptr, so if I did it myself, it would just be transparent. Does anyone know what the proper way to export a shared_ptr into python is? I suppose I could define the shared_ptr<class mine>, and only expose the "get()" function. But that would certainly be less than optimal. (I also obviously cannot wrap my function in another function that returns get(), because that would cause the shared_ptr to have the wrong lifetime.) Thanks for any help, John =:->

While you "can" do this, you are asking for more pain than anyone should be forced to have. (it is not very compliant and has lots of template quirks. AND you get pages (and pages and pages and pages) of template warnings on valid code (making debugging compile time issues much more difficult) My *strong* suggestion to you is you install at least Visual Studio .net 2003 which comes with the vc++ 7.1 compiler. If you cannot purchase this product, the command line compiler is available for free download from: http://msdn.microsoft.com/visualc/vctoolkit2003/ Hope this helps (been there, done that, got the tee-shirt :) )

[Nat] We tell boost::python the smart pointer type we're using, like this: class_<DrawableInterface, DrawablePtr, boost::noncopyable> ("DrawableInterface", no_init) ; where DrawablePtr is a typedef for the smart pointer type.

uBLAS bindings
by Daniel L Elliott 30 Oct '04

30 Oct '04

Hello, I would like to post this to uBLAS-users, but I am not yet a member. If anyone knows how to fix this, I would appreciate your help. I am working on adding identity matrices (and perhaps some others) to the gesv method of the LAPACK bindings. I have a couple questions about the code. In the template <typename MatrA, typename MatrB, typename IVec> inline int gesv (MatrA& a, IVec& ipiv, MatrB& b) method the static asserts are checking for the matrix types allowed within the gesv type? Instead of using gesv to invert a very large matrix (which would require us to create a very large identity matrix), would it be advisable to simply triangularize matrix A (maybe using LU) and use the uBLAS solver and an identity_matrix? Also, any overview of how the bindings and traits work would be very helpful! Thank you, Dan Elliott

Hi, i am a rookie as far as boost is concerned and i am trying to make boost work but just cant...on the point of giving up on it...so please help asap.... i am trying to use a scripting language called lua with my c++ source code. FOr that I felt the need to use luabind library which is completely dependent on boost.(project specific reasons for selecting luabind) As a result i need to have boost on my system. For the past 3-4 days ever since i have been trying to make boost works i have been getting all sorts of compilation errors. mainly they are as follows: C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\memory(16) : error C2059: syntax error : 'string' C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\memory(17) : error C2091: function returns function C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\memory(17) : error C2809: 'operator new' has no formal parameters C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\memory(20) : error C2954: template definitions cannot nest C:\BOOST2\BOOST\boost/mpl/aux_/integral_wrapper.hpp(88) : fatal error C1506: unrecoverable block scoping error Error executing cl.exe. i did find some solutions of the various forums of boost recommending to build the latest version from cvs in order to get rid of the scoping issue. however, that hasnt solved my case. could anyone kindly suggest some fixes, i would really appreciate it, thanks and regards, rohit __________________________________ Do you Yahoo!?

cross compile (ARM target)
by Josiah Bryan 29 Oct '04

29 Oct '04

Greets Boost users - I've just begun to play with boost for usage in a making my own GUI for my PDA (SimPAD), using AGG to render the widgets and Boost for the toolkit-type libraries (in place of the nice-but-GPLed Qt from trolltech). My question for you guys is this: 1) Is it possible to specify an abritray cross compiler for boost? - my build machine: Mandrake Linux 10.0 - cross compiler: gcc version 2.95.2 19991024 (release) - installed in /opt/Embedix/tools/bin/arm-linux-* 2) Is there already a predefined cross-compiler "target" for jam? Or maybe somebody understands what i need to do to get it crosscompiled, and can answer the question even if im not *asking* the right questions. :-) Any help is welcome..

Doesn't freshmeat/sourceforge give you that automatically somehow? I remember seeing some sort of league table of the most 'active' projects on one of the two sites, taking that figure is something that could be automated, and so wouldn't go out of date, it might be a good start? If the code isn't on freshmeat/sourceforge maybe the same thing could be setup on the server where boost source is stored? Thinking about it, you could probably list the number of hackers on each project too, that would be a useful statistic. And what about bugs? Maybe the number of bugs in the bugzilla database (if there is one) could be shown too, that would go some way to indicating stability. And if there is an issuezilla (like openoffice.org has) then that might say something about completeness? The severity rating of each bug would be useful too ... Using all this stuff in a clever way, you could really come up with a groovy stats page for each project perhaps. Hope these ideas are helpful!
