Help with Log File Creation

[subaruwrx88011]

Hey,
I am trying to create log files in a different directory than where my
executable is at. I am pretty stumped. This is what I have in psuedo
code.

std::string const M_LOG_PATH = "\\data\\logs\\";
std::string m_log_filename_with_path;
std::string filename = "log.txt";

m_log_filename_with_path = M_LOG_PATH + filename;

std::fstream file;
file.open(m_log_filename_with_path.c_str());
file << "text" << std::endl;
file.close();

So....everything works but it creates the files in the same directory
as the executable and the whole file name ends up being "//data//logs//
log.txt" instead of log.txt in the //data/logs directory.

Can anyone help???

File path names are system specific.

The "/" character works on most platforms (including recent windows
OS's) so why not try:


std::string const M_LOG_PATH = "/data/logs/"; ?


.... however, if you use the boost::file path name stuff or the Austria
C++ path name stuff, the "/" or "\" gets abstracted away and becomes OS
independant.

(The Austria filename stuff is in the netcabletv alpha).

Sorry. I forgot to tell you guys.....this is on a Debian Linux
platform!!!!

A linux system recognize "\\data\\logs" as being a simple file name -
not a directory path.

Maybe you should read all the replies in the other thread you started
because lots of people have already answered this question of yours.

Why ask basically the same question twice?

In linux / is the path seperator. \ is a valid character for a file name.
So you would definately want it:
std::string const M_LOG_PATH = "/data/logs/";
which should fix your problem.
