如何使用 boost 获取当前文件路径？

Question

How can I get the current file path using boost? Like in a.cpp, I can get

/home/src/a.cpp

I can use ＿FILE＿ macro to get this, but I can't use ＿FILE＿ due to some reason.

Any ideas?

I suppose you are looking for

#include <boost/filesystem.hpp>
    boost::filesystem::path full_path(boost::filesystem::current_path());

or

auto p = boost::filesystem::current_path()
