[Build] boost.jam usage examples
by Chris Morley 08 Dec '05

08 Dec '05

Hi, I'm after some more bjam project examples. Have been looking at the ones in the example directory, and wouldn't mind some more just to drill the usage into my head. I'm looking to use this for building our inhouse libaries, seems pretty sweet. Thanks in advance, Chris

iteration from pure abstract classes
by Hugh Hoover 08 Dec '05

08 Dec '05

I have a need to provide STL compliant iterators from an abstract class A, that is, without knowing the runtime type of the actual "collection" being iterated.. As near as I can tell, these things don't mix well. My best so far is to create an abstract "iterator_assister" which provides dereference, (in|de)crement and is_equal, and use a boost::iterator_adaptor derived class to provide the iterator the client code uses, and allocate the iterator_assister derived class from the implementation class (derived from A) that's being iterated over. This solution has obvious downsides. I can't imagine that this is a unique problem. Certainly, people significantly smarter than me have figured out a good solution to this? In my reading and browsing, though, I've never seen the problem presented, never mind solved. In my early C++ days, we used allocated iterators rather than the current STL style. Can anyone provide pointers to what I SHOULD be reading for a good solution? I believe I NEED to use abstract classes here rather than meta- programming with known types at runtime - the client code will need to iterate over classes loaded from dynamic libraries that are not known to the client code (except by abstract interface). Thanks Hugh Hoover Enumclaw Software

Re: [Boost-users] how to disable autolink feature?
by Marco Azimonti 07 Dec '05

07 Dec '05

Hello Andre, >so what to do? is there a flag to disable autolink? you can modify the file boost/config/user.hpp (http://www.boost.org/libs/config/config.htm) Quote.. /// BOOST_WHATEVER_NO_LIB Tells the config system not to automatically select which library to link against for library "whatever", replace WHATEVER in the macro name with the name of the library; for example BOOST_DATE_TIME_NO_LIB or BOOST_REGEX_NO_LIB. Normally if a compiler supports #pragma lib, then the correct library build variant will be automatically selected and linked against, simply by the act of including one of that library's headers. This macro turns that feature off. ///// Marco

how to disable autolink feature?
by Andre Krause 07 Dec '05

07 Dec '05

dear boost-users, could someone explain me how to disable the autolink feature of boost? why? 1. no hassle with configurations ( i become independent from the compile mode, i.e. debug/release/multithreaded etc) 2. i do NOT like to be forced to any naming conventions for the libs 3. i do not want to build the full boost lib, just want to include the .cpp files from the few libs of boost i'm using. just including the cpp files works, but the project does not link because visual c++ stops linking because it does not find the libs automagically and unwanted inserted into my project by autolink somewhere.. sadly there even is no simple way to disable the #pragma comment(lib, "autolinkwantstogivealongnametoiostreams.lib"). so what to do? is there a flag to disable autolink?

Hello Rene, thank you for your prompt answer and the suggestion. >I think you also have to follow all the docs for vc-7_1-stlport. I.e. >set the various STLPORT* options. Although maybe you already had that >since you where already using it? Various ways to make sure: use the >"-d+2" to see what the commands executed are and if they reference >STlport, add "-sBUILD=<stlport-version>5.0" or such to force it to use >the STLport you have. Effectively, I just copy and modify a little bit my configuration for vc_71-stlport. Unfortunately, it does not work The compilation of all the file is failing as in this case... zlib.cpp K:\coding\src\boost_1_33_1/boost/detail/sp_counted_base_w32.hpp(68): error: namespace "stlpd_std" has no member "type_info" virtual void * get_deleter( std::type_info const & ti ) = 0; compilation aborted for K:\coding\src\boost_1_33_1\libs\iostreams\build\..\src\zlib.cpp (code 4) It seems to me that it is not accepting the -stlport (and the stlport options).

Thread Library and Borland Builder 6
by Hibbeler, Jens 07 Dec '05

07 Dec '05

Hello I have sucessfully compiled the Boost Library, but I can`t use it. I get a error an the programm chrashes. I have testes it with the files in the example folder. Perhaps anyone can give me a hint, how I get ahead or where my error lies? Which I did: 0) Executed Borland builder Patch No. 4 1) Downloaded Spirit 1.6.3, set environment variable SPIRIT_ROOT on the Spirit listing 2) Set environment variable BCCROOT on c:\programme\borland\cbuilder6 3) Dowloaded the Boost LIBRARY (tried one after the other from 1_32-1_33 beta, all versions), and set the BOOST_ROOT environment variable to the listing in which I boost unpacked. 4) At the Boost tools\build\listing\build.bat executed (compiles correctly for Boland) 5) Executed tools\build\jam_src\bin.ntx86\bjam.exe "- sTOOLS=borland" install (compiled also, but with few warnings) 6) At the listing, in which I unpacked Boost, I started the libs\thread\example file once.cpp 7) I made a Porjekt to compile the file 8) I set atthe project settings the include path on C:\Boost\include\boost-1_32 9) I set atthe project attitudes the LIBRARY path on C:\Boost\lib \ 10) The program compiled and linked 11) When starting the project it crhases immediately and started the monitor, which indicates the storage addresses to me. Where does my error lie? Do I have to adjust something special in the Porjekt still? Many greetings from Hamburg, Jens

[Boost.Filesystem] Missing inline keywords in I18N branch
by Marc Viala 07 Dec '05

07 Dec '05

Hi, I'm not really sure but I think there are some missing inline declarations in "convenience.hpp" and "fstream.hpp" of Boost.fileystem for the I18N branch. I've joined the patched files Could you confirm these observations? Marc Viala www.acticm.com <http://www.acticm.com> mailto:mviala@acticm.com <mailto:mviala@acticm.com>
