tuple problems
by programmer blabla 14 Jan '04

14 Jan '04

Dear Booster's I have a problem compiling a tuple containing an enum in a namespace. For example: namespace TestTuple { enum ETestTuple { eTestTuple0 = 0, eTestTuple1 = 1 }; } void Testtuple5() { typedef boost::tuple<TestTuple::ETestTuple> Tuple; Tuple tpl; } does not compile. I am using MSVC 2003.net (7.1 version), just native code. Is this a M$ problem or is tuple broken? Also I get problem with the combination of boost::bind and tuple, for example: int i; boost::tuple<int> data; i = data.get<0>(); //ok i = boost::tuples::get<0>(data); //ok i = boost::bind(&boost::tuples::get<0>, _1)(data); //error Has anyone a clue? Btw searching lists.boost.org is very hard, because google is out of sync with the list. With kind regards, Me.

int64_t in boost/cstdint.h with GCC -std=c++98 or -ansi
by Aaron W. LaFramboise 14 Jan '04

14 Jan '04

Hi, I noticed that boost/cstdint.h does not define int64_t when GCC is in strict mode (-ansi or -std=c++98) on MinGW, Cygwin, and probably other major platforms. This seems to be because boost/cstdint.h refuses to define the type if ULLONG_MAX (or ULONG_LONG_MAX or ULONGLONG_MAX) is not defined, even if BOOST_HAS_LONG_LONG is defined. GCC, quite correctly, will not define these macros in strict mode. However, the library still probably should be defining this type. Ideally, there would be a GCC-specific work-around to prevent warnings on the use of long long in strict mode. In particular, I am using the date_time library which depends on int64_t. It would be very unfortunate and a little silly if I could not use date_time in GCC's strict mode. How would it be best to fix this? Aaron

Seeking permission to include Boost with book CD
by Matthew Wilson 13 Jan '04

13 Jan '04

Hi chaps / chappettes I am interested in including the latest released copy of Boost with the CD for my forthcoming book, Imperfect C++, to be published by Addison-Wesley this year. I have two questions: 1. Is Boost redistributable in this form? If so, from whom do I get written permission to do so? 2. What is the likely latest version of Boost that will be available around the end of Feb / beginning of March? Thanks in advance -- Matthew Wilson Director, Synesis Software (www.synesis.com.au) STLSoft moderator (http://www.stlsoft.org) Contributing editor, C/C++ Users Journal (www.synesis.com.au/articles.html#columns) -----------------------------------------------------

re: API documentation ?
by Vikram Anantha 13 Jan '04

Is there any place where I can look at the complete API documentation for the boost libraries. Something generated by doxygen or doc++ or something like that. Thanks Vik

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...*/ } }
