Re: [Boost-users] Multi_index Container

Hi Joaquín, Éric I appreciate your response, Before that I got some workaround from the web and the snippet I have written to port it to my existing project worked until I face real problem. My observation is like when I have Ordered_index with std::string, the code I have written compiles really well and works also. But when I remove this ordered_index, the code does not compile. Here is the code that compiles: <<Multi_index_container_working.txt>> Here is the code that does not compile: <<Multi_index_container_not_working.txt>> If you see the difference I have only two lines commented. ... //ordered_non_unique<tag<name>,BOOST_MULTI_INDEX_MEMBER(employee,std::string,name) >, .... .... //typedef boost::multi_index::index<employee_set,name>::type employee_set_by_name;... Same boost::multi_index::index<employee_set,ssnumber>::type is not working if the std::string is not indexed. right now I am working with dummy string. But I need to scrap the string and have some real code in place that should go into my project. If I am not able to solve this. I can not use multi_index_container and it is real loss for me. Help always appreciated. Thanks in advance. aashit ps: please consider these txt files are cpp files. ________________________________ From: boost-users-bounces(a)lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Joaquín Mª López Muñoz Sent: Tuesday, February 07, 2006 9:39 PM To: boost-users(a)lists.boost.org Subject: Re: [Boost-users] Multi_index Container Hello Aashit, "Soni, Aashit" ha escrito: Hi all, I am newbie to Boost library.

I am using MSVC SP6 on Win XP . This is primarily the problem: To make MSVC 6.0 compile a program using Boost.MultiIndex you've got to observe some stricter rules than in the normal case. Please read the section on MSVC 6.0 at http://boost.org/libs/multi_index/doc/compiler_specifics.html#msvc_60 typedef employee_set::index<employee_set,ssnumber>::type employee_set_by_ssn; Problem #1: MSVC 6.0 does not support the "index" nested typedef. Instead, write typedef index<employee_set,ssnumber>::type employee_set_by_ssn; employee_set_by_ssn& ssn_index=es.get<2>(); Problem #2: MSVC 6.0 does not support the get member function, use the global version instead: employee_set_by_ssn& ssn_index=get<2>(es); With these changes, and also tweaking /Zm and /ZI (as explained in the aforementioned section), your program compiles. Bare in mind that your compiler is very old and broken and making Boost.MultiIndex work for it can be quite a challenge, although it is doable. Good luck with your project, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

[program_options]allow_unregistered() ignored?
by Merrill Cornish 08 Feb '06

08 Feb '06

I have this problem that while program options works just fine for processing registered options, an unregistered option triggers a MS runtime exception (I'm using MinGW, so it uses MS runtime) that can't be caught at the C++ level. My store() function is shown below: po::store(po::command_line_parser(argc, argv). options(all_verbose). positional(pd). run(), vm); I saw the allow_unregistered() feature. I thought this would be a way to get all illegal command line options "out of the way" so they couldn't trigger the exception. So I modified the above to be: po::store(po::command_line_parser(argc, argv). options(all_verbose). positional(pd). allow_unregistered(). run(), vm); However, putting an illegal argument on the command line, say --x, still gives the message, "This application has requested the Runtime to terminate it in an unusual way." Is an unregistered option triggering some sort of NULL access? Merrill

Creating static libraries of boost
by boostguy＠kapiladhanvi.com 08 Feb '06

08 Feb '06

Hi all, I am trying to compile boost into static libraries on windows, but I am not able to create static libraries. Can someone point out what I am missing ? I am on a windows XP machine with mingW installed and in path. This is a simple task but somehow I am not getting static libraries. The command line I am using on my command prompt is : bjam "-sTOOLS=gcc" "-sBUILD=release static multi" stage The output libraries created are .lib and .dll, but the filenames are not starting with libboost-*.lib , they are just boost-*.lib. According to the http://boost.org/more/getting_started.html#Build_Install , windows static libraries should have lib*.lib as the format for the name.. Can someone tell me what I am doing wrong ? Thanks. Dhanvi

This is basically what I was trying. #include <iostream> #include <boost/regex.hpp> int main() { std::string input = "sand._12"; boost::regex reg(".*\._[0-9]+"); If you're trying to escape the "." you probably also need to escape the "\" by using "\\". It is a C string after all.

Now my if_enabled() function compiles and works for boost::adjacency_matrix<>. I'm gonna define read_net() function for boost::adjacency_matrix<> just by first read graph to appropriate boost::adjacency_list<> and then construct matrix from list. Is this approach ok?

linker problems with boost::test examples

Hi! I have some problems getting started with boost::test. I tried to build a Vc7 project using the code of http://boost.org/libs/test/test/result_report_test.cpp, but this fails to compile due to unresolved symbol init_unit_test_suite. libboost_unit_test_framework-vc71-mt-sgd-1_33_1.lib(framework.obj) : error LNK2019: Nicht aufgelöstes externes Symbol '"class boost::unit_test::test_suite * __cdecl init_unit_test_suite(int,char * * const)" (?init_unit_test_suite@@YAPAVtest_suite@unit_test@boost@@HQAPAD@Z)', verwiesen in Funktion '"void __cdecl boost::unit_test::framework::init(int,char * * const)" (?init@framework@unit_test@boost@@YAXHQAPAD@Z)' Debug/test.exe : fatal error LNK1120: 1 unaufgelöste externe Verweise Am I missing anything? I found out that #include <boost/test/included/test_exec_monitor.hpp> resolves the problem, but is this the correct solution? best regards, Markus
