[Multi-Index] composite_key problems
by Andreas Volz 30 Oct '05

30 Oct '05

Hi, I like to build a data structure and like to access it with different keys, so I try multi_index for this. My data structure looks like this: struct learnedMeasure { // target_name + measure_name together is the composite key std::string target_name; std::string measure_name; float negative; float positive; float zero; } I like to access this data structure like this in SQL: SELECT measure, Negative, Positive, Zero from tabelle WHERE target_name='xxx' SELECT Target_name, Negative, Positive, Zero from tabelle WHERE measure_name='xxx' SELECT Negative,Positive,Zero from tabelle WHERE measure_name='xxx' AND Target_name='yyy' I hacked the basic example to get this working. My example compiles, but if I execute it, I get only warnings: probe: /usr/include/boost/multi_index/detail/index_iterator.hpp:107: typename Node::value_type& boost::multi_index::detail::index_iterator<Node, Container>::operator*() const [with Node = Container>boost::multi_index::detail::ordered_index_node<boost:: multi_index::detail::index_node_base<learnedMeasure> Container>>, Container = Container>>boost::multi_index::detail::ordered_index<boost:: multi_index::composite_key<learnedMeasure, Container>>boost::multi_index::member<learnedMeasure, std::string, Container>>&learnedMeasure::measu .... more warnings I put my example code online. Perhaps someone could take a look in it and help me to find this problem. http://cpp.sourceforge.net/?show=9550 regards Andreas

I've attached the error log to this message. I've tried searching through the list archive for related problems but came back empty handed (although some posts seem to blame the widechar support?)

any interest in lightweight version of boost::format
by Oliver Schoenborn 30 Oct '05

30 Oct '05

I know there is a boost::format and it's great. However, I needed something faster and with more "conventional" syntax. That's the coutf library. I've been using it for a few months and it's great. Just to be clear, I'm not suggesting a replacement of boost::format, which has several features that coutf does not. However in many cases you don't need those and that's why coutf is a fair bit faster. Also the syntax is more conventional and several people have mentioned they prefer that. I know Alexandrescu has also created something similar to coutf (I think he called it Printf), but I think mine is lighter, I think most people are not too concerned about not being able to printf 45 parameters, plus it has the Fmt/FmtGuard stuff :) . Anyways the docs and code are at http://noptrlib.sf.net/utils/coutf, just did another update today. Coutf could be a good second alternative to boost::format for some people. Here are some examples of use: coutf("Program started at %s:%s:%s\n", hours, minutes, seconds); cerrf("Error: file %s, line %5s invalid\n", filename, lineNum); std::string msg = strf("Hex of %s is %04Xs", 123, 123); int count = 10; std::ofstream ff("someFile.txt"); // prints array in hex format { FmtGuard fmt(ff, "%0#4x"); for (int i=0;i<count;i++) scoutf( ff, 1 + intArray[i], '\n' ); } // print in dec format scoutf( ff, count ); BOOST_LOG(trace) << strf("File %s at line %s\n", __FILE__, __LINE__); Cheers, Oliver

64-bit Boost Regression testing.
by Nik Yevik 28 Oct '05

28 Oct '05

Hi, I have built 64-bit Boost libraries on SUSE Linux ES 9 (SLES 9)for IBM POWER/PowerPC(PPC) using gcc 3.3.3 and 3.4.4. in both 32-bit and 64-bit. Now, I also want to run Boost 1.33.0 regresion test with gcc 3.4.4 in 64-bit to see if there are any problems with 64-bit compilation. Regression test helper programs and tests themselves are being built in 64-bit OK. However, the run tests give the error message: ***************************************************** unknown location(0): fatal error in "some_test_name": signal: memory access violation *** errors detected in test suite "Some Test Suite Name"; see standard output for details EXIT STATUS: 200 ***************************************************** I enabled detailed output and here is an example of what I see during the regression test (Just one orbitrary chosen test - the rest show pretty much the same picture).: ****************************************************** MkDir1 ../bin/boost/libs/assign/test/multi_index_container.test mkdir "../bin/boost/libs/assign/test/multi_index_container.test" MkDir1 ../bin/boost/libs/assign/test/multi_index_container.test/gcc mkdir "../bin/boost/libs/assign/test/multi_index_container.test/gcc" MkDir1 ../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug mkdir "../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug" MkDir1 ../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug/address-model-64 mkdir "../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug/address-model-64" MkDir1 ../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug/address-model-64/architecture-power mkdir "../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug/address-model-64/architecture-power" gcc-C++-action ../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug/address-model-64/architecture-power/multi_index_container.o set -e "/home/nik/gcc-3.4.4-ppc-install/bin/g++" -m64 -c -Wall -ftemplate-depth-255 -g -O0 -fno-inline -mcpu=powerpc64 -m64 -I"../bin/boost/libs/assign/test" -I"/home/nik/boost_1_33_0" -I "/home/nik/boost_1_33_0" -o "../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug/address-model-64/architecture-power/multi_index_container.o" "../libs/assign/test/multi_index_container.cpp" "/usr/bin/objcopy" --set-section-flags .debug_str=contents,debug "../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug/address-model-64/architecture-power/multi_index_container.o" gcc-Link-action ../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug/address-model-64/architecture-power/multi_index_container set -e LD_LIBRARY_PATH=/home/nik/gcc-3.4.4-ppc-install/lib64:/home/nik/gcc-3.4.4-ppc-install/lib:$LD_LIBRARY_PATH export LD_LIBRARY_PATH "/home/nik/gcc-3.4.4-ppc-install/bin/g++" -m64 -g -m64 -o "../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug/address-model-64/architecture-power/multi_index_container" -L"/home/nik/gcc-3.4.4-ppc-install/lib64" -L"../bin/boost/libs/test/build/libboost_unit_test_framework.a/gcc/debug/address-model-64/architecture-power" -L"/home/nik/gcc-3.4.4-ppc-install/lib" "../bin/boost/libs/assign/test/multi_index_container.test/gcc/debug/address-model-64/architecture-power/multi_index_container.o" "../bin/boost/libs/test/build/libboost_unit_test_framework.a/gcc/debug/address-model-64/architecture-power/libboost_unit_test_framework.a" "../bin/boost/libs/test/build/libboost_unit_test_framework.a/gcc/debug/address-model-64/architecture-power/libboost_unit_test_framework.a" -Wl,-rpath-link,.

[date_time] is it possible to parse a string out from given patterns?
by Roman Morokutti 28 Oct '05

28 Oct '05

Is it possible to parse a date out from a string like this? The example below is from a java program. private static final String PLANSTART_PATTERN = "dd.MM.yyyy HH:mm"; /** * Converts a String of type 01.01.2005 to a * CDate object * @param sForcamDate * @return the converted object */ private CDate convertToCDate(String sForcamDate, String sPattern) { if (sForcamDate == null || sForcamDate.length() == 0) return null; try { SimpleDateFormat sdf = new SimpleDateFormat(sPattern, Locale.getDefault()); sdf.parse(sForcamDate); Calendar cal = sdf.getCalendar(); return new CDate(cal.getTime()); } catch (ParseException ex) { return null; } } For more information on SimpleDateFormat see: http://java.sun.com/j2se/1.4.2/docs/api/java/text/SimpleDateFormat.html

A basic interior properties question
by Gat, Yoram 28 Oct '05

28 Oct '05

Hi all, I just started using BGL and created the following program (MSVS 7.1), storing some data in an interior property and then retrieving them: #include "boost/graph/adjacency_list.hpp" struct NodeProperties { int a, b, c; }; typedef boost::adjacency_list< boost::listS,boost::listS,boost::undirectedS, boost::property<boost::vertex_all_t,NodeProperties> > Graph; typedef boost::graph_traits<Graph>::vertex_descriptor VertexDescriptor; typedef boost::property_map<Graph,boost::vertex_all_t>::type AllMap; int main(int argc, char const *argv[]) { Graph graph; AllMap allMap = get(boost::vertex_all,graph); VertexDescriptor vd = boost::add_vertex(graph); NodeProperties np; np.a = 1; np.b = 2; np.c = 3; allMap[vd] = np; NodeProperties np1 = allMap[vd]; // const AllMap::value_type &vt = boost::get(allMap,vd); // NodeProperties np1 = vt.m_value; return 0; } For which I get the following error: c:\Documents and Settings\ygat\Desktop\Work\InternalProperty\InternalProperty.cpp(24): error C2440: 'initializing' : cannot convert from 'boost::detail::vertex_property_map<Graph,PropertyTag>::Property' to 'NodeProperties' with [ Graph=Graph, PropertyTag=boost::vertex_all_t ] After some poking around, I discovered that if I replace the offending line with the two commented lines, things work. Is this the right way to retrieve the data? Why can the NodeProperties object be on the rhs but not on the lhs of an assignment to the property map? Thanks, Yoram

[multi_index] non-intrusive keys
by Adi Shavit 28 Oct '05

28 Oct '05

Hi, In my application I used a multi_map of multi_maps as a data structure to provide indexing with 2 keys, say long strings. Access is logarithmic on both keys and the keys are not part of the stored object, thus are potentially only stored once. I'd like to use multi_index as a more elegant replacement. However, I'm not clear about where the keys are stored. In my app, the keys are stored separately from the data, as the keys to maps, as part of the map data structure. It seems that in multi_index the keys have to be inside the stored data. In this case, 10 objects with the same key(s) will all have to hold copies of the keys (as members). Is there a way to avoid this? I hope I'm clear, Thanks, Adi

Boost T-Shirts @ Cafe Press
by Jeff Garland 28 Oct '05

28 Oct '05

Hi All - As everyone is probably already aware, we have a new Boost logo that was created by booster Zoltan 'cad' Juhasz. As part of the final logo refinement process, the moderators asked Zoltan if he could create T-Shirts with the new logo. We also felt it was appropriate that Zoltan be the beneficiary of any proceeds associated with the T-Shirts since it was his tireless work that went into the logo and T-Shirt design. With that in mind, I'm delighted to announce that Zoltan worked out some T-Shirt designs and has set up a couple shops at Cafe Press so that people can purchase Boost T-Shirts. - http://www.cafepress.com/boostlibs - http://www.cafepress.com/boostlibsb If you have suggestions or other ideas you can find Zoltan's contact info at: http://people.inf.elte.hu/cad Jeff

result_of && VC7.1

Hi, Experimenting with boost::result_of under VC7.1 and 8... --- template <typename T> struct A{ template <typename F> struct result; template <typename U,typename V> struct result<A(U,V)>{ typedef U type; }; template <typename U,typename V> U operator()(U const&,V const&) { return U(); } }; //typedef A<int>::result<A<int>(int,int)>::type result_; typedef boost::result_of<A<int>(float,char)>::type result; --- c:\boost\boost\utility\result_of.hpp(43) : error C2027: use of undefined type 'A<T>::result<F>' with [ T=int ] and [ F=A<int> (float,char) ] Am I actually using result_of correctly here, or have I misunderstood something? If the result_ typedef is uncommented then it behaves as I would expect. Is there a way to successfully use result_of like this with VC? Thanks, Richard.
