Boost Program Options won't work with GLIBCXX_DEBUG

问题

I have the following sample code:

#include <iostream>
#include <boost/program_options.hpp>

int main ( int ac, char *av[] ) {
    // Declare the supported options.
    boost::program_options::options_description desc("Allowed options");
    desc.add_options()("help", "produce help message");

    boost::program_options::variables_map vm;
    boost::program_options::store(boost::program_options::parse_command_line(ac, av, desc), vm);
    return 0;
}

It compiles fine using e.g. g++ test.cpp -lboost_program_options. However if I try to activate GCC bounds checking with the call g++ test.cpp -lboost_program_options -D_GLIBCXX_DEBUG, it throws the following linker error:

/tmp/ccZLdZ1g.o: In function `boost::program_options::basic_command_line_parser<char>::basic_command_line_parser(int, char const* const*)':
test.cpp:(.text._ZN5boost15program_options25basic_command_line_parserIcEC2EiPKPKc[_ZN5boost15program_options25basic_command_line_parserIcEC5EiPKPKc]+0x97): undefined reference to `boost::program_options::detail::cmdline::cmdline(std::__debug::vector<std::string, std::allocator<std::string> > const&)'
collect2: error: ld returned 1 exit status

As far as I understand the linker can't find the function boost::program_options::detail::cmdline::cmdline(std::__debug::vector<std::string, std::allocator<std::string> > const&), because its argument is replaced by a debug vector instead of normal std::vector. But why does this happen? And does anyone know a workaround, to make Boost Program Options work with GLIBCXX_DEBUG?

I use the following system:

Debian Wheezy
g++ (Debian 4.7.2-5) 4.7.2
libboost-all-dev 1.49.0.1, installed via aptitude

Thanks for any help

回答1:

The error message is very clear here, the linker cannot find the symbol

boost::program_options::detail::cmdline::cmdline(std::__debug::vector<std::string, std::allocator<std::string> > const&)

note the additional __debug namespace, which implies you are building with _GLIBCXX_DEBUG. This won't work since your package maintainer did not build the boost libraries with this defined, hence the linker error. You have a few options

remove _GLIBCXX_DEBUG from whatever translation units include the program options headers. This might require some refactoring depending on what you're trying to solve with iterator debugging enabled.
build the boost libraries with -D_GLIBCCX_DEBUG. This also may not be trivial, though the boost build system is fairly straightforward.
