Hi, I am trying to build the regex library with ICU (MSVC 6.0). I get the following error: Z:\dev\3rd\boost_1_33_0\boost/regex/icu.hpp(42) : error C2039: 'Locale' : is not a member of '`global namespace'' Any help would be greatly appreciated. Thanks Louis

[Pre-processing] String Litereal Comparison for Equality
by Hossein Haeri 17 Sep '05

17 Sep '05

Dear all, Is there anyway (say using a utility in BOOST_PP) at pre-processing phase to compare string literals for equality?

Build errors and crash with 1.33.0 under Mac OS X CodeWarrior
by Allen Cronce 17 Sep '05

17 Sep '05

Hi all, I just updated from boost 1.32.0 to 1.33.0 for a CodeWarrior MSL/carbon project under Mac OS X. There were several build errors stemming from the fact that "check" is already defined in /usr/include/AssertMacros.h. For now I dealt with this my modifying my copy of the boost libraries to substitute _check for check. This is of course an ugly solution, but I wanted to move forward. Unfortunately now I'm seeing crashes with code that worked fine with 1.32.0. Here's some test code that demonstrates the crash: _tprintf(_T("\nTest a vector of boost shared_ptr's:\n")); typedef boost::shared_ptr<std::string> SharedPtrString; typedef vector<SharedPtrString> StringContainer; typedef vector<SharedPtrString>::iterator StringContainerIterator; { SharedPtrString sharedPtrString1(new std::string("Hi there!")); SharedPtrString sharedPtrString2(new std::string("Hi there!")); _tprintf( _T(" sharedPtrString1->c_str() = \"%s\"\n"), sharedPtrString1->c_str() ); _tprintf( _T(" sharedPtrString2->c_str() = \"%s\"\n"), sharedPtrString2->c_str() ); } // We never get here because of an access error Basically when the SharedPtrString goes out of scope, I get an access error deep in the allocation code. Does anyone have suggestions for resolving these issues? Note that I could go back to 1.32.0, but I want to use the new Pointer Container Library. Best regards, -- Allen Cronce

[iostream]: Simple sinks result in runtime error
by Marius Renn 17 Sep '05

17 Sep '05

Hi all, This is my first post, so please let me know if I am doing anything wrong. I am having trouble using the new iostream headers in Boost 3.3. I cannot get simple Sinks to function correctly. Take the following code for example: namespace bio = boost::iostreams; int main() { typedef bio::stream<bio::null_sink> nullsink; nullsink out; out << "Ignore me"; } This code always results in a runtime assertion failure: /usr/local/include/boost/iostreams/detail/optional.hpp:54: failed assertion `initialized_' What am I doing wrong? Any help would be greatly appreciated. Cheers, Marius

compiling boost.signals without exception
by Martin Sarrazac 17 Sep '05

17 Sep '05

Hi, compiler: mingw gcc 3.4.4 I would like to compile boost.signals without exception handling, I read somewhere about the <exception-handling> feature so I tried: bjam --builddir=c:\temp -sTOOLS=mingw "-sBUILD=debug <exception-handling>off <runtime-link>dynamic <threading>single" --libdir=C:\boost\lib\noe --with-signals -d2 install without success, it compiles fine but not without exception handling. specifically the -fno-exception command line option should be passed to gcc and it's not. I had a look at tools/build/v1/gcc-tools.jam and I found this line for rtti support for instance: flags gcc C++FLAGS <rtti>off : -fno-rtti ; However there is nothing equivalent for exceptions... On a side note I don't know how to give a new tag to the 'no exception' version of the library, so I compiled it in an other directory (--libdir=C:\boost\lib\noe). However I would much prefer to give it a specific name. Is there somewhere information about all the -sBUILD flags can be found? Can't seem to locate it. Thanks for your help

Problems going from Serialization 1.32 to 1.33
by Stefan Arentz 17 Sep '05

17 Sep '05

Hello fellow Boost users, Consider the following program: #include <sstream> #include <string> #include <vector> #include <boost/archive/text_oarchive.hpp> #include <boost/serialization/base_object.hpp> #include <boost/serialization/string.hpp> #include <boost/serialization/vector.hpp> template <typename T> std::string archive(T thing) { std::ostringstream oss; boost::archive::text_oarchive oa(oss); oa << thing; return oss.str(); } typedef std::vector< std::string > parameters_t; int main() { parameters_t parameters; parameters.push_back("a"); parameters.push_back("b"); std::string s = archive<parameters_t>(parameters); return 0; } When I compile this with Boost 1.32 it compiles and works fine. However, with Boost.1.33 it fails with: /usr/local/include/boost/archive/detail/oserializer.hpp: In function `void boost::archive::save(Archive&, T&) [with Archive = boost::archive::text_oarchive, T = std::vector<std::string, std::allocator<std::string> >]': /usr/local/include/boost/archive/basic_text_oarchive.hpp:78: instantiated from `void boost::archive::basic_text_oarchive<Archive>::save_override(T&, int) [with T = std::vector<std::string, std::allocator<std::string> >, Archive = boost::archive::text_oarchive]' /usr/local/include/boost/archive/detail/interface_oarchive.hpp:85: instantiated from `Archive& boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) [with T = parameters_t, Archive = boost::archive::text_oarchive]' test.cpp:16: instantiated from `std::string archive(T) [with T = parameters_t]' test.cpp:28: instantiated from here /usr/local/include/boost/archive/detail/oserializer.hpp:566: error: incomplete type `boost::STATIC_ASSERTION_FAILURE<false>' does not have member `value' I'm not sure what to change. Is this correct behaviour? S.

[filesystem] function to determine available space
by Beman Dawes 16 Sep '05

16 Sep '05

I'm planning to add a filesystem function to determine available disk space. Perhaps something like: struct space_status { boost::uintmax_t available; // free space available to user boost::uintmax_t total; // total space on volume }; space_status filesystem_space( const path & p ); Comments? Better suggestions for the names? --Beman

I don't think you can insert/delete stuff like in a vector.

Help on Boost.MultiArray
by Adewole, Mike 16 Sep '05

16 Sep '05

Hi all, Does anyone know how to insert and delete a range of rows and/or columns in the multiarray class documented at http://www.boost.org/libs/multi_array/doc/ ? What performance guarantees can I expect for these operations ? I'm a little pressed for time and haven't been able to figure out how to do this on my own. The statement that "The number of elements will remain fixed for the duration of a multi_array's lifetime" on the documentation page suggests that these operations may not even be supported, but I'm not sure if I'm misunderstanding the statement or not. Thanks a lot. -------------------------------------------------------- Mike Adewole ACNielsen, Global Decision Support Services ph: 905-475-3344x2411 fx: 905-475-8357 mike.adewole(a)acnielsen.ca --------------------------------------------------------
