c++ - Integrating 'google test' and 'boost program options' -

i have program uses google test, , boost program options library parsing options. problem google test has it's own option parsers, need filter out before giving options google test.

for example, when run hello use follows

hello --option1=x --gtest_filter=footest.* 

--option1 option use before passing --gtest_filter option google test.

when run following code, got exception --gtest_filter not option use boost program options. how can combine options boost program options doesn't recognize give gtest's input?

#include <boost/program_options.hpp> namespace po = boost::program_options;  #include <iostream> #include <fstream> #include <iterator> using namespace std;  #include <gtest/gtest.h>     int main(int argc, char **argv) {     // filter out options google related options survive     try {         int opt;         string config_file;          po::options_description generic("generic options");         generic.add_options()             ("option1,o", "print version string")             ;              ...                }     catch(exception& e) // *****************     {         cout << e.what() << "\n";         return 1;     }       testing::initgoogletest(&argc, argv);     return run_all_tests(); } 

i found option ignore unknown options in page - http://www.boost.org/doc/libs/1_45_0/doc/html/program_options/howto.html#id2075428

store(po::command_line_parser(argc, argv).          options(cmdline_options).positional(p).allow_unregistered().run(), vm);
