Debugging Flex applications with mm.cfg and flashlog.txt let us track trace statements and error messages for projects running in the browser using the debug mode. Since I haven’t done it since 2001 I completely forget what to do and came across couple of issues, so I figured I’ll throw a post for other people that may have the same issue.
You first need to create the txt file and directories here:
/Users/YourUserName/Library/Preferences/Macromedia/Flash\ Player/Logs/flashlog.txt
Then you need to create the mm.cfg file in both location:
/Library/Application Support/Macromedia/mm.cfg
/Users/YourUserName/mm.cfg
Then paste the follwing code in the mm.cfg:
ErrorReportingEnable=1
TraceOutputFileEnable=1
MaxWarnings=0
Initially, I pasted the code only in the first directory and couldn’t get it to work, not sure why, so place the file in both directories to play it safe.
I am running the Flash Debug Player 10, on Mac OS X.
To see the messages as they come on Terminal, navigate to the flashlog directory and type in:
tail -f flashlog.txt
I Hope you find this tip handy.
I think that Adobe breaks this with every Flash Player update. I can’t get it to work for me at all.
I had to restart Safari to get it to work. Reloading the application wasn’t enought.
Just a heads up it looks like you only need to put the mm.cfg in /Users/YourUserName/mm.cfg and not in both places on a Mac. Your millage may vary…
