cross compiling boost libs
by Uwe Sander 12 Jan '04

12 Jan '04

Hi, I would like to compile the boost libs for the Win32 platform using mingw on Linux. I have the required stuff installed and I know how to do such a cross compilation if I have a 'configure' based project but I do not know how to tell bjam what I am trying to achieve. Any hint? Thanks Uwe

Boost Include headers
by jling＠cmmt.ubc.ca 12 Jan '04

12 Jan '04

I need to include the following line in my code. #include "boost/type_traits/object_traits.hpp" My source file is in the root directory of the boost package that I extracted. But, I get errors like: boost/type_traits/object_traits.hpp:19: boost/type_traits/ice.hpp: No such file or directory boost/type_traits/object_traits.hpp:22: boost/type_traits/fwd.hpp: No such file or directory boost/type_traits/object_traits.hpp:25: boost/type_traits/composite_traits.hpp: No such file or directory etc ... I noticed that in say "boost/type_traits/ice.hpp" it also has header files it refers to, that look in "boost/type_traits/" directory, but relative to that header file, ice.hpp, there is no such directory path ... only from the root where my source file is, does that path exist. How does this work and how to I get my code to compile? Thanks, John

Using Smart Assert Library with MSVC 7.0 and 7.1
by Ferentinos, Jerry 12 Jan '04

12 Jan '04

Hi All, I'm having some trouble getting John Torjo's Smart Assert library to work with MSVC 7.0 and 7.1. Here's the error I get when compiling the example in boost_root\libs\smart_assert\example\enforce.cpp on MSVC 7.0 (7.1 yields a similar error): --snip-- c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\vector(95) : error C2664: 'std::_Vector_val<_Ty,_Alloc>::_Vector_val(_Alloc)' : cannot convert parameter 1 from 'const std::_Vector_val<_Ty,_Alloc>::_Alty' to 'boost::smart_assert::Private::smart_assert_alloc<type>' with [ _Ty=boost::smart_assert::assert_context::val_and_str, _Alloc=boost::smart_assert::Private::smart_assert_alloc<boost::smart_assert: :assert_context::val_and_str> ] and [ _Ty=boost::smart_assert::assert_context::val_and_str, _Alloc=boost::smart_assert::Private::smart_assert_alloc<boost::smart_assert: :assert_context::val_and_str> ] and [ type=boost::smart_assert::assert_context::val_and_str ] No constructor could take the source type, or constructor overload resolution was ambiguous c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\vector(93) : while compiling class-template member function 'std::vector<_Ty,_Ax>::vector(const std::vector<_Ty,_Ax>::_Myt &)' with [ _Ty=boost::smart_assert::assert_context::val_and_str, _Ax=boost::smart_assert::Private::smart_assert_alloc<boost::smart_assert::as sert_context::val_and_str> ] c:\boost_1_30_0\boost\smart_assert\priv\fwd\smart_assert_context.hpp(155) : see reference to class template instantiation 'std::vector<_Ty,_Ax>' being compiled with [ _Ty=boost::smart_assert::assert_context::val_and_str, _Ax=boost::smart_assert::Private::smart_assert_alloc<boost::smart_assert::as sert_context::val_and_str> ] --snip-- I hand instantiated "const std::_Vector_val<_Ty,_Alloc>::_Alty" and I got "boost::smart_assert::Private::smart_assert_alloc<type>" (where _Ty, _Alloc, and type have been replaced by their actual parameter values) so why is MSVC reporting an error? Has anyone else come across this problem? If so, how did you solve it? I tried searching the archive and came up with nothing, mostly because clicking on a search result brings you to an altogether different message. Any clues?

Put it somewhere else and add the Boost directory to the include search path (on the command line this is usually done with a -I option).

globbing with regex??
by Rich Johnson 12 Jan '04

12 Jan '04

I'm new to regex and would like to use it to match filenames, but I'd like to stick with a csh/bash syntax. Is this advisable? If so, would anyone have a set of regex traits for this syntax? If not, could someone point me in the right direction? Thanks, --rich An sample usage is: namespace fs = boost::filesystem char * dirname; /*...glob_regex_traits definition */ boost::regex expr( "*.cpp" , /*...glob_regex_traits...*/ ); for( fs::directory_iterator iter( fs:path( dirname ) ) ; iter != fs::directory_iterator() ; ++iter ) { boost::cmatch match_data if( regex_match( iter->leaf().c_str(), match_data, expr ) ) { /*...do something...*/ } }

Weird freeze with boost::thread on Win2K
by Viktor Lundström 10 Jan '04

10 Jan '04

Hi! I'm using boost::thread on MSVC6/Win2k. When I start two processes which both use boost::thread, the second process waits for up to a minute or two before starting. The process doesn't bug, it just hangs there for a while and then starts. Is this a known problem? Regards, Viktor Lundström

NEWBIE QUESTIONS ABOUT BGL
by Hugues Joly 09 Jan '04

09 Jan '04

Hi, I've read most of the online documentation about the Boost Graph Library and I've tried a few examples but some questions remain unanswered: Properties: - Once we have a property map for vertices or edges, do we have to assign a value to each vertex (or edge) of the graph? (My preliminary tests tell me that we have to.) - Is the graph the only mean to iterate through all the elements of a property map that it owns? - What is the difference between a graph and a property graph: when would we choose to use a graph interface instead of a property graph? - How can I attach a local property to an element of a subgraph and still have the original property unchanged for the corresponding element on the parent graph? (At the time beeing it seems impossible to do so.) - How can I define a custom property within a specific namespace? PROBLEMS: It seems that there are compilers' limitations regarding the number of properties (and their value type) that can be attached to an adjacency_list (at least with CodeWarrior). Thanks in advance. __________________________________________________________ Lèche-vitrine ou lèche-écran ? magasinage.yahoo.ca

MAKING A SEARCHABLE ARCHIVE OF THE boost-users' MAILING LIST
by Hugues Joly 09 Jan '04

09 Jan '04

Hi, I think that a searchable archive would be a big help in providing newcomers with answers on basic topics. At least, a downloadable archive would do the job. Who could take care of that? __________________________________________________________ Lèche-vitrine ou lèche-écran ? magasinage.yahoo.ca
