How Can I set CALIBRE_CONFIG_DIRECTORY ?

[ryanlee]

Hi all!

I'm using ubuntu 10.04

I'm having this problem when I using PHP shell_exec()

"OSError: [Errno 13] Permission denied: '/root/.config'"

so I could get answer like that "set enviornment CALIBRE_CONFIG_DIRECTORY"

But I don't know where can I set this enviornment well..

I've been googling since got above answer but I couldn't understand their cases b/c I'm a newbie about ubuntu..

Could you let me know how to resolve that problem for me?

echo $XDG_CONFIG_HOME
/root/.config

echo $CALIBRE_CONFIG_DIRECTORY
/home/myhome/.config/calibre


So I did

export XDG_CONFIG_HOME=/home/myhome/.config
export CALIBRE_CONFIG_DIRECTORY=/home/myhome/.config

Then still show me this error
OSError: [Errno 13] Permission denied: '/root/.config


what's wrong?

Are you starting calibre from the process where you did the export?

Export works only for the process doing the export and all sub-processes. If you are using the GUI to start calibre, you will need to set the variable and export it using the GUI environment tool.

However, as you are using PHP, I assume there is a web server involved somewhere. Assuming it is apache, you need to ensure that apache has the correct setting of the environment variable when it starts, so that PHP sees it, so that Calibre sees it. See http://httpd.apache.org/docs/1.3/env.html.

Alternatively, set the environment variable in your PHP script. See 'putenv' in the PHP manual.

Alternatively squared: instead of directly executing a calibre program, exec a shell that sets the environment appropriately, then execs the calibre program.
