Hello all, I have a newbie question for you. I'm trying Boost for the very first time. I'm also not terribly experienced with C++. I'm using, Eclipse Kepler (latest) Mingw 3.20 (latest) Boost_1_54_0 on a 64-bit Windows 7 machine. I followed this tutorial to configure Boost to be used with Mingw and Eclipse: http://theseekersquill.wordpress.com/2010/08/24/howto-boost-mingw/ Sections 1-6 performed as expected. The 7th and final step is when a "hello world" like application finally compiles and links Boost into a .exe. I cut-n-paste the following code from Boost's Getting Started tutorial ( http://www.boost.org/doc/libs/1_54_0/more/getting_started/windows.html): <snip> #include <boost/regex.hpp> #include <iostream> #include <string> int main() { std::string line; boost::regex pat( "^Subject: (Re: |Aw: )*(.*)" ); while (std::cin) { std::getline(std::cin, line); boost::smatch matches; if (boost::regex_match(line, matches, pat)) std::cout << matches[2] << std::endl; } } </snip> The output of the build is, <snip> 12:20:46 **** Rebuild of configuration Debug for project BoostRegexExample1 **** Info: Internal Builder is used for build g++ "-Ic:\\boost_1_54_0" -O0 -g3 -Wall -c -fmessage-length=0 -o BoostRegexExample1.o "..\\BoostRegexExample1.cpp" g++ "-LC:\\boost_1_54_0\\stage\\lib" -o BoostRegexExample1.exe BoostRegexExample1.o -lboost_regex-mgw46-mt-1_54 12:20:52 Build Finished (took 5s.992ms) </snip> If I try to run that application within Eclipse the terminal simply states the application terminated. If I go to a terminal and run the .exe (using a text file as in input as directed in the Getting Started document) I get, *"Procedure entry point _ZNSt16invalid_argumentD2Ev could not be located in the dynamic link library libstdc++-6.dll"* Any ideas why this is happening? And, what I can do to get past this? Thanks, Joe
