[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

Hi, I'm new to regex. 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? Thank you once again, --dima

linker problems with boost::test examples
by Markus Werle 07 Feb '06

07 Feb '06

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

Multi_index Container
by Soni, Aashit 07 Feb '06

07 Feb '06

Hi all, I am newbie to Boost library. I am trying to use multi_index_container library in my project. The problem I have at my hands needs One Hash index and one ordered indexed. I refer the Boost tutorial and Advance topic and tried to write the following snippet. But when I compiled it gives compilation error. I searched lot of different options and tried to fix it but I could not able to do it so. If you can guide me how to shut the compilation errors it will be great. If anyone of you is having any decent example tried out for Hash having ordered indexes please send it to me so I can go through and build my logic on top of that.... Code Follows.

Getting started with Boost: what did you need to know?
by David Abrahams 07 Feb '06

07 Feb '06

I'm giving a talk about getting started with Boost (https://www.cmpevents.com/SDw6/a.asp?option=G&V=3&id=271893) and I thought it would be a good idea to solicit input from those who have recently gone through the process. What do you wish someone had explained to you? With what did you need hand-holding? Based on this feedback I expect to make some improvements to the Boost website, also. Any information you can give me will be much appreciated. Thanks, -- Dave Abrahams Boost Consulting www.boost-consulting.com
