How to reduce the boost library size
by Jianhong Wang 24 Jan '06

24 Jan '06

Hi I compiled version 1.33.1 under a Windows XP machine with MingW (gcc 3.4.2). The compiling is very smoothing. However the size of directory "boost" is around 1.27 GB. I believe there is some command to clean the building lib, but I could not find it. Any suggestion? thanks!

Tokenizer usage, combining escaped_list_ and char_?
by Jeremy Tudisco 24 Jan '06

24 Jan '06

I'm attempting to process a scripting language from a file through tokenizer (only recently found out about Spirit, more on that later), and am having difficulties, namely, in processing input like this: "[ ExampleRoutine input; switch( input.messageNumber ) { 1: "Number 1"; 2: "Stand. On one foot (and jump around)"; 3: ! a comment to be ignored input.messageNumber = 1; break; } ];" The ending quotes mark the input as a string literal, the internal are part of the file. The problem comes from the fact that I need to process certain separators as tokens, such as braces, parentheses, periods, end lines, etc, but also allow escape characters in the case of the quotes, which should be treated as one returned token. My current method of processing this is: typedef char_separator<char> CharSep; typedef tokenizer<CharSep> CharTokenizer; typedef CharTokenizer::iterator CTokenIter; const CharSep g_RoutineSep(" \t\n,", "\"';[]{}()<>.!"); #define S_QUOTE "\"" ... // meanwhile, inside a function body CharTokenizer tok( getRoutineFromFile(), g_RoutineSep ); CTokenIter curTok( tok.begin() ); for(; ( curTok != tok.end() ) && ( *curTok != S_CBRACKET ); ++curTok ) { string curWord; if( ( *curTok == S_QUOTE ) { for(++curTok; ( *curTok != S_QUOTE ) && ( curTok != tok.end() ); ++curTok) { curWord += *curTok + ' '; // sure, we could check to see if *curTok is a punctation mark, and if so // not include that last space, but a better way must exist! } } else { // assume it's a command word, and process it here } } Of course, this is prone to gross misinterpretation, as "switch( input.messageNumber )" would be handled in each iteration as "switch", "(", "input", ".", "messageNumber", ")". Yet, this same functionality breaks the string literal into unnatural spacings, as the above code would turn it into "Stand . On one foot ( and jump around ) ", which isn't desired. However, as it stands, escape_list_separator doesn't return the separators, it just acts upon them, so all that fancy operator parsing isn't possible out of the box, requiring breaking things like "switch(" and "input.messageNumber" into separate things. Possible, yes, but extra work. So, the question. Could my needs be satisfied by defining my own TokenizerFunction, and if so, is there a simpler/more exhaustive reference besides the page? Or, conversely, is it time to look into Spirit? - Veni, Vidi, Vemaili. I came, I saw, I replied. -- Jeremy Tudisco, circa now.

Re: [Boost-users] How to reduce the boost library size
by Merrill Cornish 24 Jan '06

Jianhong, If you did a simple Boost build without restricting the output, then your Boost output directory will have many variants of each library. For example, you will have static and dynamic libraries; libraries with and without debug information, libraries with and without threading. And, for each of the above, you will have a two copies of the library named with and without the Boost version number (e.g., -1_31_1) as a suffix. If you decided what combination of debug/threading/static/version you want, you can delete the others, or at least move them elsewhere. Merrill

boost thread does not honour BOOST_ALL_DYN_LINK
by Inge Norum 24 Jan '06

24 Jan '06

The boost thread library does not honour the BOOST_ALL_DYN_LINK setting in config/user.hpp. Thread used to be only available as a dynamically linked library in version 1.31, and I see a note about this in the comment for BOOST_ALL_DYN_LINK. I guess that it now ought to honour this general setting, to avoid defaulting to static linkage even when this is defined? Regards, Inge Norum thread/detail/config.hpp: #if defined(BOOST_THREAD_BUILD_DLL) //Build dll #elif defined(BOOST_THREAD_BUILD_LIB) //Build lib #elif defined(BOOST_THREAD_USE_DLL) //Use dll #elif defined(BOOST_THREAD_USE_LIB) //Use lib #else //Use default # if defined(BOOST_HAS_WINTHREADS) # if defined(BOOST_MSVC) || defined(BOOST_INTEL_WIN) //For compilers supporting auto-tss cleanup //with Boost.Threads lib, use Boost.Threads lib # define BOOST_THREAD_USE_LIB # else //For compilers not yet supporting auto-tss cleanup //with Boost.Threads lib, use Boost.Threads dll # define BOOST_THREAD_USE_DLL # endif # else # define BOOST_THREAD_USE_LIB # endif #endif

Re: [Boost-users] Multi-Index compound key synthesis via MPL
by Joaquín Mª López Muñoz 24 Jan '06

[Luke, this message from you shows up at Google Groups frontend, but somehow it hasn't really made it to the users list. Responding to the list in the hope that at least this answer gets properly processed.] Luke Meyers ha escrito: > The indexed_by construct for a multi_index_container can be replaced by > an mpl::vector, so that the list can be synthesized. I would like to > do the same thing with compound_key, to synthesize such a key based on > a list of types. Can I do this? Alas there's no version of composite_key accepting an MPL sequence instead of the direct enumeration of the constituent key extractors. But with a little MPL and preprocessor stuff, however, you can do what you want, see the attached snippet. HTH, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

[Boost][Bind] How to bind template function member
by Marc Viala 24 Jan '06

24 Jan '06

Hi, I would like to know how I can use boost::bind with template function member? To explain my problem, you will find hereafter an example code that demonstrates it. In this code, when we try to bind the function member X::g the compiler failed with tons of error message. Am I doing something wrong? Best regards, Marc Viala mailto:mviala@acticm.com ----------------------------------- Platform: VC++ 7.1 Boost 1.33.1 ----------------------------------- #include <boost/bind.hpp> #include <boost/function.hpp> struct X { template<typename A, typename B> void g(A& a, B& b) { std::cout << a << " " << b << '\n' ; } void f(int& i) { std::cout << i << '\n'; } } ; template<typename A, typename B> void e(A& a, B& b) { std::cout << a << " " << b << '\n' ; } int main(int argc, char* argv[]) { int a = 10, b = 11 ; X x ; boost::function<void (void)> pe = boost::bind(&e<int,int>, a, b) ; // <- OK pe() ; boost::function<void (void)> pg = boost::bind(&X::g<int,int>, &x, a, b) ; // <- Don't compile? pg() ; boost::function<void (void)> pf = boost::bind(&X::f, &x, a) ; // <- OK pf() ; }

beginners problems linking serialization library
by Michael Shapiro 24 Jan '06

24 Jan '06

I am having problems linking a program using the serialization library. I have made a small program, considerably simpler than the demo.cpp listed at http://www.boost.org/libs/serialization/doc/tutorial.html and I have also tried linking demo.cpp itself. My hpp files are in /home/mshapiro.local/boost/include/boost-1_32/boost/ My libraries are in /home/mshapiro.local/boost/lib/ I have tried linking this code with gcc 3.4.5 on a linux machine using gcc -I/home/mshapiro.local/boost/include/boost-1_32/ \ -L/home/mshapiro.local/boost/lib/ \ -lboost_serialization-gcc \ demo.cpp I have tried many variations on this! (For example, I have tried g++ instead of gcc, I have tried all variations on the serialization library, such as boost_serialization-gcc-d-1_32, etc, I have tried turning off warnings as suggested in the compiler specific issues.) I can compile using the -c flag, but I cannot link it. I get a large number of error messages all of which look much like /tmp/ccuSnkzu.o(.gnu.linkonce.t._ZN5boost7archive18text_oarchive_implINS0_13text_oarchiveEED1Ev+0x51): In function `boost::archive::text_oarchive_impl<boost::archive::text_oarchive>::~text_oarchive_impl()': : undefined reference to `boost::archive::basic_text_oprimitive<std::basic_ostream<char, std::char_traits<char> > >::~basic_text_oprimitive()' I can find various references to this exact problem in the newsgroups, but can find no solution to it. Your help would be greatly appreciated. Many thanks in advance, Michael Shapiro

Yep, I see. You're right. Well, you can refer to get<> as follows boost::tuples::get<N,typename Tuple::inherited> Note that this is not relying on undocumented implementation, so called "const lists" are explained and made public at http://boost.org/libs/tuple/doc/tuple_advanced_interface.html So I'd say you can use the former reference to get safely. > > However, I am wondering if there would be a problem to declare the > thin > wrapper simply like this (example with the const version): > > template< int N , > typename Tuple > > inline > typename tuples::access_traits< > typename tuples::element< N , Tuples >::type > >::const_type > get( const Tuple& t ) > { > return tuples::get< N >( c ) ; > } > > ? That would also work, but my proposal above is simpler.

BUG: example boost_file_dependencies.cpp does not compile.

Hi, I have tried to compile the example boost_file_dependencies.cpp using version 1.33.1 under Linux (gcc) and Windows XP (VC 7.1) and get the same errors.
