Is is possible to place multi_arrays in maps???
by Ramon F. Herrera 01 Mar '11

I need a set of multi_arrays, and so far it seems that I can only have one of them (with the same name) at a time. What I need is a loop where the original multi_array is resized, filled and the current copy saved in a map. Is that possible? TIA, -RFH

boost::range : comparison operators
by er 01 Mar '11

01 Mar '11

Hello, I'm interested in make_iterator_range( container ); defined in http://svn.boost.org/svn/boost/trunk/boost/range/iterator_range_core.hpp in order to adapt container to have comparison operators. While, template< class IteratorT, class ForwardRange > inline bool operator<( const ForwardRange& l, const iterator_range<IteratorT>& r ) is defined, operator>, for example, isn't. Is there a functionality that provides all operators? Thanks.

Boost + ICU in Windows with MinGW
by Jose Mondefo 01 Mar '11

Hi mates, I have a question about boost compiled with icu support for using it in another library (freeling). All this work is in windows using mingw32, the icu 4.2.1 library and boost 1_40. I compile boost with the following bjam line $ bjam toolset=gcc variant=release threading=multi threadapi=win32 link=shared runtime-link=shared --prefix=$PREFIX --user-config=tools/build/v2/user-config.jam -j 2 --with-filesystem --with-program_options --with-regex define=U_STATIC_IMPLEMENTATION=1 -sHAVE_ICU=1 -sNO_BZIP2=1 -sNO_ZLIB=1 --layout=tagged -a --build-type=complete stage I applied the following patch before compilation, without it I don't get the boost_regex-mt.lib and boost_regex_mt.dll, but the libboost_regex-mt.lib. https://build.opensuse.org/package/view_file?file=boost-regexdll.patch&pack… This compilation works great, and also the compilation of the freeling library, which generates an exe. But after that, If I try to run the generated exe (with the boost dlls ) I get this error terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error> > what(): Could not initialize ICU resources Could anyone help me undersanding this error? I suppose it has something to do with some missing ICU files, and I'm sure i make some mistake in the compilation process but I didn't get where is it. I also tried building boost with link=static runtime-link=static, but of course if I do that I don't get the boost_regex-mt.lib but the libbost_regex-mt.lib (and i need the dynamic library for compilation of the freeling library). I now this is not the ICU forum, but if it helps for catching the problem ICU was compiled this way a) apply some diffs from this patch http://devs.openttd.org/~terkhen/libicu/libicu_4_6_mingw32.diff (reference link http://wiki.openttd.org/Compiling_on_MinGW#Compiling_libicu), to make it compile in MinGW (not all cause there are some difference between icu 4.2.1 and 4.6). b) After that run $ ./configure --prefix=/mingw/ --disable-strict --disable-threads $ make install This compilation doesn't generate any dll, only the libs for making boost compile. Thanks in advance and best regards, and sorry if this mails is a mess, I only try to give all the information I think is useful.

Re: [Boost-users] boost::asio from C++ Forms App in VS 2010

Hi all, Thanks for your all your replies. I went for managed C++ because I wanted to create a GUI very quickly - Windows Forms are ideal for this and they only work with managed code. Since then I have been busy re-writing the GUI in unmanaged, proper C++ in a new VS project using the Win32API (in the same VS2010 on the same machine). I'm happy to say that I am not experiencing the problems I had before and everything works as it should.

Re: [Boost-users] Compilation error using boost::filtered_graph when trying to access graph properties via boost::graph_bundle
by Tony Cook 01 Mar '11

Hi Jeremiah ** Confirmed fixed :) Thanks ** You might want to look at reverse_graph.hpp as it worked around the problem using: typename boost::graph_property_type<base_type>::type& operator[](graph_bundle_t) { return get_property(*this); } typename boost::graph_property_type<base_type>::type const& operator[](graph_bundle_t) const { return get_property(*this); } I adapted this fix approach for my local copy of filtered_graph.hpp like so: typename Graph::graph_bundled& operator[](graph_bundle_t) { return const_cast<Graph&>(this->m_g)[boost::graph_bundle]; } typename Graph::graph_bundled const& operator[](graph_bundle_t) const { return this->m_g[boost::graph_bundle]; } But your fix is general so the code in reverse_graph.hpp is most likely redundant now - I've chucked my local patch away. Thanks again, Tony > Could you please see if this problem still appears in r69404 of the Boost trunk (just committed)?
