I’m trying to write to a file that is not in the directory that the executable is in; I also want it to work no matter where the executable is (I believe that would rule out using “..”). I need this to work on Linux. Thank-you.

A relative path is usually resolved starting from the running directory, which is not necessarily the executable directory (rather the current directory in the shell from which the executable is launched).
Under linux, you can read the directory of the executable with:
or you could use boost
fs::pathandfs::system_complete. Then you have to remove from that string the last component, which is the executable name.Once you have the path of the executable directory, append “/..” to it and you will get the directory above the executable directory.
