boost::filesystem relative path and current directory?

Question

How can I use boost::filesystem::path to specify a relative path on Windows? This attempt fails:

boost:filesystem::path full_path("../asset/toolbox"); // invalid path or directory. 

Maybe to help me debug, how to get the current working directory with boost::filesystem?

Answer 1

getcwd = boost::filesystem::path full_path(boost::filesystem::current_path()); 

Example:

boost::filesystem::path full_path(boost::filesystem::current_path()); std::cout << "Current path is : " << full_path << std::endl; 

To access current_path one needs to add #include <boost/filesystem.hpp>.

Answer 2

Try the system_complete function.

namespace fs = boost::filesystem;  fs::path full_path = fs::system_complete("../asset/toolbox"); 

This mimics exactly how the OS itself would resolve relative paths.
