This code works under Windows7, but not under LinuxMint Cinnamon 17.2.
Does anyone have a fix for making it work under LinuxMint?

Thanks

PS - the WU runs under LinuxMint, it's app_config.xml that does not work.
If you need any additional info, I'll be happy to provide it.
I am not an expert, so be easy on me, please.

In what way it doesn't work?
Does the client say it found the app_config.xml file?
Is the BOINC version new enough to know about app_config.xml?
Did you put it into right directory?
Does the client have permissions to read it?

In what way it doesn't work?
Code calls for four WU per GPU.
Running 0.896 CPUs + 1 NVIDIA GPU.

Does the client say it found the app_config.xml file?
Have not queried Collatz Conjecture.
Decided to ask BOINC first.

Is the BOINC version new enough to know about app_config.xml?
Version: 7.2.42 (x64)
This is the version downloaded by Synaptic Package Manager.

Did you put it into right directory?
/var/lib/boinc-client/projects/boinc.thesonntags.com_collatz

Does the client have permissions to read it?
YES

Juha meant in the Event Log BOINC keeps (and shows from the BOINC Manager - Crtl-Shift-E) on your local machine. If you re-read config files - there's a Manager menu item for that too - the log will re-display the app_config.xml detections (no need to restart BOINC).

Fixed it. Thanks for the assist.

The client is not reading the app_config.xml. If it were, there would be any entry right after the time entry like this:

10-3-2015 2:47:38 AM |  | Local time is UTC -4 hours
10-3-2015 2:47:38 AM | The Lattice Project | Found app_config.xml

The first thing to check is the permissions for the file. If you installed from repositories, then the client is running under user boinc. In a terminal window, navigate to the project directory and then enter the following command:

sudo chown boinc:boinc app_config.xml

Then try the read config files option in BOINC Manager to see if the client now reads the file.
