Hi there! I am getting this warning: "Warning: implicit conversion to 'cstring' from a non-const location: pd_from_disk; this will become a compile time error in the future [CStringConv]" From this code: proc player_data(data_path: cstring): cstring {.cdecl, exportc, dynlib.} = var pd_from_disk: string str_data_path: string = $data_path try: pd_from_disk = readLines(str_data_path, 1)[0] except: pd_from_disk = fall_back_string CPlayer_Data = pd_from_disk return CPlayer_Data
