Hello, I tried to use boost in Eclipse on Windows. My testing program:
#include <iostream>
#include <boost/filesystem.hpp>
using namespace boost::filesystem;
int main(int argc, char* argv[])
{
if (argc < 2)
{
std::cout << "Usage: tut1 path\n";
return 1;
}
std::cout << argv[1] << " " << file_size(argv[1]) << '\n';
return 0;
}
Thanks for help.
The build error message:

I am able to build the binaries now. They are placed under C:\boost_1_47_0\stage\lib. To test the filesystem library. I added "boost_filesystem-mgw46-mt-1_47" to the MinGW C++ linker's 'libraries', but I still get an undefined reference problem:
There are two libraries built for filesystem under stage/lib:
libboost_filesystem-mgw46-mt-1_47.a
libboost_filesystem-mgw46-mt-d-1_47.a
Anything wrong here?
