I tried defining a struct locally and throwing it and the catch works fine. any ideas? thx dxc ------------------------------------------------------------ #include <iostream> #include #include "boost/filesystem.hpp" int main(int argc, const char** argv) { if(argc != 2) { std::cout << "usage: a.out filename\n"; exit(1); } const char* a_path = argv[1]; try { boost::filesystem::exists(a_path); } catch(const boost::filesystem::filesystem_error& e) { std::cout << "caught filesystem_error\n"; std::cout << e.what() << "\n"; exit(1); } catch(const std::exception& e) { std::cout << "caught some other error\n"; std::cout << e.what() << "\n"; exit(1); } catch(...) { std::cout << "caught unknown exception\n"; exit(1); } return 0; }
