Where to store debug output?

[Kukulkan]

Hi,

I'm currently porting a windows app to linux (must run on CentOS, RedHat and Ubuntu). At windows, I wrote some error-logs to %TEMP% path.

But what is the correct place for logfiles on Linux?

I try'd to write to /var/log/, but my app is not allowed to create a new file here (only root, but my app never runs with root permissions).

Can I use OpenFile() to write to some log that is declared for such use? For example stderr? But how can the user then see the content?

I'm new to Linux development and this is somewhat confusing.

If you have a normal application you should probably log to
$HOME/.yourapp/

Syslog is normally used for System-relevant logs produced by
daemons or other critical applications (e.g. webservers). Syslog
writes to /var/log and can be used through a command-line tool
"logger" or through syslog-functions. Choose whatever works
best for you.

Cheers!

Hi remi,

Thanks for your input. I think I will use $HOME/.app.

/tmp is also a place where you can create temporary files.

Yes, indeed a good idea. Thank you.

Hello,

Code: Select all

Debug GetTemporaryDirectory()

Here on Linux Mint 12 :

/tmp/

I guess on windows this command return something like

C:\Windows\Temp

Best regards.
