FileX Paths for root directory access

I'm porting over some linux code and the base directory is specified as with two defines for ROOT "." and SEP "/" - this is prepended to all file names that the code opens (converted to fx_file_open).

If I try to open "./myfile.dat", the open fails. If I open "/myfile.dat", it's ok.  

Is there a way around this - I don't want to really hack up the linux app to much.

Thanks

Larry
