Some errors in Boost.Log
by Jens Seidel 21 Sep '07

21 Sep '07

Hi, I know that Boost.Log is not an official Boost library but I hope that this is the right place to collect infos and errors of this library (especially as the author does not respond). I always missed the fact Boost.Log is not able to redirect messages of a special priority (say err) to a file. Redirection is only based on the logger name (e.g. "project.file_accesses"). It is possible to match all priorities higher than a choosen one but if you collect many debug outputs you will miss a few errors in the large log. Now I noticed that I can just create separate loggers such as logger_err and output an err message to the specified logger and additionally to logger_err. Now I'm able to redirect err-level outputs via logger_err *only*, great! I missed a solution like this in the library (yep, it's not difficult, but ...) and it may be useful for others too. Nevertheless the documentation manipulating_logs.html or the library contains errors: <quote> Here are the predefined levels: info (1000) warn (1200) dbg (1400) err (1600) fatal (2000) disable_all ( std::numeric_limits<unsigned>::max() ) default_level (1000) enable_all (0) </quote> First of all dbg should have a much lower priority than info, not a higher one! Also it should be disable_all (0) enable_all ( std::numeric_limits<unsigned>::max() ) In the past I noticed (and reported to the author who ignored my mail) also trivial compile errors with latest g++ compiler (missing ";", ...). I will continue reporting issues to this list, just in case another person wants to maintain Boost.Log or the author will continue his work (which I hope) ... What logger framework do Boost users use? I do not remember reading much about Boost.Log on this list ... Jens

Hi All, I am having trouble getting bjam to run on my Ubuntu 6.06 system - its complaining about a missing GLIBC_2.4.

Well, seems like the compiler is having a hard time with dependent nested types. Probably newer versions of GCC will pose less problems. Fortunately, you can use global variants for nth_index etc., which happen to be easier for the compiler. So, instead of typedef typename mi::nth_index<0>::type mi_by_value; you can write typedef typename nth_index<mi,0>::type mi_by_value; Besides, you write in several places: m_c.get<...>() but as the calls are in dependent contexts you have to write them like this instead: m_c.template get<...>() or like this, as you're alreading doing in MultiIndex::MultiIndex(): get<...>(m_c) The attached code includes all the corrections above and have been verified to compile and run OK with GCC 3.2. Hope this helps, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

[boost-users] Library names with mingw-g++ onm windows
by John Femiani 21 Sep '07

21 Sep '07

How does one invoke bjam on the version of boost in SVN-Trunk so that mingw-g++ libraries use '.a' as a suffix instead of '.lib' ? When I use the mingw g++ compiler on Windows I expect it to produce libraries ending with '.a' since that is what the compiler typically looks for when linking with something like: -lboost_filesystem-mt-d Granted I could just put the whole library name -llibboost_filesystem_mt-d.lib but is there a way to make bjam produce .a as a suffix instead? Shouldn't this be the default behavior if I am using a gcc based toolset? -- John

[multi-index]/shared_ptr template issue - compiles on MSVC8 but not gcc
by Mark Schlegel 20 Sep '07

20 Sep '07

Hi, I'm using boost versions 1.33.1 and 1.34.1 with gcc 4.1.2 (Linux) and boost 1.33.1 with gcc 3.3.2 on solaris and MSVC8 I'm trying to use multi_index as a container indexed by two integers in a class called MapEntry. The two indices represent a unique key number "key" and a possibly non-unique timestamp "age". To make it generic I have the data in a shared_ptr<T> in the MapEntry class because I wanted to use the aged map functionality with many classes in the shared_ptr: // the tags struct keytag { }; struct agetag { }; template <typename T> struct MapEntry { .... stripped out all constructors and methods ... int key; int age; private: boost::shared_ptr<T> payload; }; and the multi_index_container setup as a wrapper class since C++ doesn't have typedef templates because I figured I needed that to get the "T" into the MapEntry<T> .... template<typename T> class AgedMap { typedef T map_type; public: typedef multi_index_container< MapEntry<T>, indexed_by< ordered_unique< tag<keytag>, BOOST_MULTI_INDEX_MEMBER(MapEntry<T>, int, key) >, ordered_non_unique< tag<agetag>, BOOST_MULTI_INDEX_MEMBER(MapEntry<T>, int, age) > > > AGEDMAPTYPE; }; and in main() I declare the container as: AgedMap<AH_ENTRY>::AGEDMAPTYPE am; and do insert, finds and erases into it. My problem is that it seems that if I use the T template to call my flush_by_age template function : template <typename T, typename MIContainer> void flush_by_age(MIContainer& mic, int timeout) { ..... which is called from main() as (note AH_ENTRY is a very simple struct with just a single int in it and cctor/ctor/dtor for testing) flush_by_age<AH_ENTRY, AHS_MAP>(am, AGELIMIT); and use that T to define what AGE_INDEX is inside it: // this hard coded one compiles and runs on all my platforms // but loses the whole point of genericness //typedef AgedMap<AH_ENTRY>::AGEDMAPTYPE::index<agetag>::type AGE_INDEX; // this AGE_INDEX does not on gcc but DOES compile on MSVC8 typedef AgedMap<T>::AGEDMAPTYPE::index<agetag>::type AGE_INDEX; I get a compiler error at the AGE_INDEX typedef in gcc 3.3.2 (solaris 10): aged_map.cc: In function `void flush_by_age(MIContainer&, int)': aged_map.cc:159: warning: `boost::multi_index::multi_index_container<Value1, IndexSpecifierList1, Allocator1>::index<agetag>::type' is implicitly a typename and a more verbose one on gcc 4.1.2 (Fedora 6 Linux): aged_map.cc: In function ÃÂ¢void flush_by_age(MIContainer&, int)ÃÂ¢: aged_map.cc:159: error: non-template 'index' used as template aged_map.cc:159: note: use ÃÂ¢boost::multi_index::multi_index_container<MapEntry<T>, boost::multi_index::indexed_by<boost::multi_index::ordered_unique< boost::multi_index::tag<keytag, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na>, boost::multi_index::member<MapEntry<T>, int, (& MapEntry<T>::key)>, mpl_::na>, boost::multi_index::ordered_non_unique< boost::multi_index::tag<agetag, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na>, boost::multi_index::member<MapEntry<T>, int, (& MapEntry<T>::age)>, mpl_::na>, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na>, std::allocator<MapEntry<T> > >::template index' to indicate that it is a template aged_map.cc:159: error: too few template-parameter-lists But MSVC 8 compiles it fine and it runs. But if I hard code the class in my AGE_INDEX typedef to "<AH_ENTRY>" to replace the <T> in the flush_by_age() it compiles fine on ALL those compilers and they all run ok. I'm wanting to find out what I can possibly do because this would be a very useful class for since I currently have to put the aging information in another container where this let's me do it in one. I use unix and Windows and on Windows the compiler must be MSVC and on unix gcc. I tried making the typename explicit by adding "typename" using the hint from the solaris error but that didn't help. I'm guessing I've got some syntax typo like a missing & or const somewhere ? thanks, Mark

sp_counted_base.hpp and VxWorks
by Daniel P Furlani 20 Sep '07

20 Sep '07

The file sp_counted_base.hpp checks a bunch of macros to determine which architecture-specific include file to use. One of those checks is: #elif defined( __GNUC__ ) && ( defined( __powerpc__ ) || defined( __ppc__ ) ) I'm using VxWorks 6.5. Their version of gcc defines __ppc but not __ppc__. This is some of the output from "ccppc -dD -E emptyfile.cpp": #define __GNUC__ 3 #define _ARCH_PPC 1 #define __ppc 1 #define CPU_FAMILY PPC #define CPU PPC604 #define __vxworks 1 #define __VXWORKS__ 1 If the sp_counted_base.hpp check was written like this: #elif defined( __GNUC__ ) && ( defined( __powerpc__ ) || defined( __ppc__ ) || defined( __ppc ) ) Then I would see the correct file get included. Is this a change that should be made to the boost source or do you feel it is a problem with my compiler? Regards, -Dan

[multi_index] composite_key question
by Jeffrey Holle 20 Sep '07

20 Sep '07

I've a multi_index container that has a composite_key index which is used to express a "checker board" like concept. I need to iterator over all rows, from 0 to n. I know how to employ equal_range(make_tuple(y)) to get the elements within a specific row, but how do I determine n? The only way I can think of doing this is doing a linear search using another index. Is there a better way?

You don't need to use static_pointer_cast<> or limit yourself to using base class shared_ptr<>s, as has been suggested. The solution is to pass by value instead of by reference. Then the compiler has a chance to perform an implicit conversion from one shared_ptr type to another. In other words, just remove the "&" from the signature of AddChild(). void AddChild(shPtrA child); The conversion won't occur when you pass by reference because shPtrB does not inherit from shPtrA.

[serialization] Error with bitfields under PathScale EKO compiler
by Bill Lear 20 Sep '07

20 Sep '07

I have a standard serialize method, working under various flavors of gcc and the Intel C++ compilers: struct ElementEnum { enum Origin { Standard, Base, Custom }; }; class Foo { ... ElementEnum::Origin origin : 4; template<...> void serialize(...) { ar & BOOST_SERIALIZATION_NVP(origin); } }; However, under the PathScale EKO compiler (pathCC), I get an error: "error: invalid initialization of reference of type Origin& from expression of type const unsigned char:4." Apparently make_nvp takes as its second argument a non-const reference. It appears that non-const references are illegal under this compiler, and, who knows, perhaps the latest C++ standard?? I was able to create a test case that caused this same error. However, the test case also failed under gcc and the Intel compiler, so the test case (appended below after my sig) is not narrow enough, apparently. If I rewrite the serialization method to not use the BOOST_SERIALIZATION_NVP macro at all, the code works. Any help on working around this (aside from tearing out BOOST_SERIALIAZATION_NVP() calls altogether) would be appreciated. Bill // test case to provoke the same error that I got compiling // serialization code under PathScale EKO compiler. #include <iostream> using namespace std; template <class T> void print(T& t) { cout << "t is now: " << t << endl; } struct Foo { int itsie : 4; }; int main() { Foo f; print(f.itsie); }

boost::ptr_vector null check bloat
by Miles Bader 20 Sep '07

20 Sep '07

I tried changing some of my code that used std::vector<foo *> to using boost::ptr_vector<foo> (to get automatic deallocation and the slightly nicer syntax), but the resulting compiled code seems oddly bloated compared to the original code using std::vector. My intuition is that the two should generally compile to largely equivalent object code, except where there's a necessary functional difference. Some of the problem seems to be that it does null-pointer checking at _access_ time, instead of when adding new entries. The result is that (for instance) calls to operator[] end up with an "unnecessary" null check, which drags in tons of stuff related to the accompanying assertion failure, some of which is apparently unshared across object files, like the long __PRETTY_FUNCTION__ strings passed to the assertion failure call. What's the general impression people have of boost::ptr_vector and related classes? Do people use it? Does it have a "bloat" reputation? Thanks, -Miles -- "Suppose we've chosen the wrong god.

Getting errors while compiling a project
by Vitali Gontsharuk 20 Sep '07

20 Sep '07

Hello! I'm getting a strange problem trying to build a project of my colleague with exactly the same source, project and lib-files. I'm using Visual Studio C++ 2005 Express Edition German version with Service Pack 1. He has the same version, but in English, maybe this could be relevant. He has programmed a transforming tool which makes heavy usage of different boost features. Actually, his project used to compile on my PC previously, but then I made a Windows Update and simultaneously added some changes (included Xerces, Xalan and also changed something in my project, but didn't change anything in his project). After that I can't compile his project. I know that we use the same resource files because I downloaded them from our local svn server. I'm not sure whether I can make even parts of the code public. But maybe the full error report could be sufficient to make some hints where the problem could lie in. I would really appreciate your help, because I have already lost so much time figuring out what the problem can be. But as I'm only a novice to all the BOOST libraries, I don't have an overview of it and the typical errors and how to interpret them (or the combination of errors), which is vital in programming using templates etc. I send the full error report as an attachment! I thank all the answerers in advance! Best wishes, Vitali Gontsharuk

Hi, I am facing problems building boost 1.33.1 on my MacBook Pro mac OS X 10.4.9. I have attached the errors below. Any help regarding this would be highly appreciated. Thanks, Ashima ./tools/build/jam_src/bin.macosxx86/bjam -sPYTHON_ROOT=/System/Library/Frameworks/Python.framework/Versions/2.3 -sPYTHON_VERSION=2.3 -sTOOLS=darwin Building Boost.Regex with the optional Unicode/ICU support disabled. Please refer to the Boost.Regex documentation for more information (and if you don't know what ICU is then you probably don't need it). ...found 9834 targets... ...updating 6 targets...

Well, you're right this global nth_index<...> and similar metafunctions are not much publicized: they are only documented in the reference, and in a little noticeable way: look for "// multi_index_container associated global class templates:" at http://www.boost.org/libs/multi_index/doc/reference/multi_index_container.h… I haven't given these global metafunctions more publicity so as to not confuse readers, given that the nested versions ought to be enough in most cases --except for broken compilers like MSVC 6.0 and, seemingly, low versions of GCC. > Again thanks alot.

Link errors using Boost & STLPort with VC8

Hi all, I read about the following discussion when I encountered a similar issue (using -MTd -D_STLP_DEBUG=1 on the command line) and googled: John Maddock wrote: > Jason Ivey wrote: > > 1>LINK : fatal error LNK1104: cannot open file > > 'stlportstld_x.5.1.lib' > > > > The problem is that all of the stlport libraries are named > > stlportstld.5.1.lib or similar.

It seems to me the reason for the failure is that there are some DLL-related conflicts. In _detect_dll_or_lib.h: # if defined (_STLP_RUNTIME_DLL) # if !defined (_STLP_USE_STATIC_LIB) # if !defined (_STLP_USE_DYNAMIC_LIB) # define _STLP_USE_DYNAMIC_LIB # endif # else /* The user is forcing use of STLport as a dynamic library.

And, according to your suggestion, if I manually build libboost_regex-vc71-mt-sgdp-1_34_1.lib with cl /MTd /D_STLP_DEBUG=1 *.cpp followed by lib /out:libboost_regex-vc71-mt-sgdp-1_34_1.lib *.obj Everything is fine. Another thing to notice here is that unlike the case of STLport 4.6.2, files like boost*p-1_34_1.lib and boost*p-1_34_1.dll are NOT created. Is it related? BTW, without -D__STL_DEBUG=1 or -D_STLP_DEBUG=1 Boost will complain "STLPort debug versions are built with /D_STLP_DEBUG=1" and "Build options aren't compatible with pre-built libraries", so this should not be an issue. Comments? Best regards, Yongwei -- Wu Yongwei URL: http://wyw.dcweb.cn/

Using multi-index as container type in templated class
by Paul.VanHagen＠shell.com 19 Sep '07

19 Sep '07

Hello, I am having trouble using a boost::multi_index_container type in a template class where the multi-index value type is depending on the template arg type of the class. In particular, I'm getting compiler errors when trying to define the iterator and index types using the "type" typedefs in the multi_index container. Apparently, at compile time the index and iterator types cannot be deduced resulting in errors like "cannot convert to typename, etc.". I'm using GCC 3.3.1 and Boost 1.34.1. Following code demonstrates the problem: // std includes #include <iostream> // boost includes #include "boost/multi_index_container.hpp" #include "boost/multi_index/ordered_index.hpp" #include "boost/multi_index/sequenced_index.hpp" using namespace std; using namespace boost; using namespace boost::multi_index; // try also class keyword here template<typename T> class MultiIndex { public: typedef T value_type; typedef mpl::vector< ordered_non_unique<identity<value_type> >, sequenced<> > index_list_t; // multi-index typedef typedef multi_index_container< value_type, index_list_t > mi; // typedefs for index types typedef typename mi::nth_index<0>::type mi_by_value; typedef typename mi::nth_index<1>::type mi_as_seq; // typedefs for index iterators typedef typename mi::nth_index_iterator<0>::type mi_it; typedef typename mi::nth_index_iterator<1>::type mi_seq_it; MultiIndex() { // add pair to multi-index container mi_as_seq& seq = get<1>(m_c); seq.push_back(9); seq.push_back(8); seq.push_back(7); seq.push_back(6); seq.push_back(5); seq.push_back(4); seq.push_back(3); seq.push_back(2); seq.push_back(1); seq.push_back(0); } void exec() { // access as sequence cout << "\nAccessing as sequence:" << endl; copy(m_c.get<1>().begin(), m_c.get<1>().end(), ostream_iterator<int>(cout, " ")); cout << endl; // access by value cout << "\nAccessing ordered:" << endl; copy(m_c.get<0>().begin(), m_c.get<0>().end(), ostream_iterator<int>(cout, " ")); cout << endl; } private: mi m_c; }; int main(int argc, char** argv) { MultiIndex<int> mi; mi.exec(); } It's probably obvious what is wrong with this code but I just don't see it. I tried a non-templated version and that compiles (and works) fine. Thanks, Paul
