Code::Blocks will not write data files on Linux Mint

[Raspnex]

I tried several ways with wx methods to save a data file unsuccessfully, then I loaded a new project without the wxWidget, and tried to create the file with fstream and that also failed to write a data file.  is there a permission somewhere I need to set, that may be blocking my programs from writing a file? 

Thanks for any advice on solving this issue.

I'm not really sure what I did, but I got wxTextFile to work at adding to an existing file.
