Flightgear Development Question

Hi all

A while back I gave Flightgear a shot, liked it and tried making a portable version.
It worked half but I couldnt redirect the APPDATA variable to the usb drive. I tried redirecting it the same way I did it with lots of other Apps but it didn't work.
I am at the end of my knowledge here and it would be cool if I would find someone willing to take a look at it and see if I made any errors of if maybe there is an other way of doing it.

I know its a huge package but I'd like it anyhow Smiling

Thanks!

You can move it back and forth the way we do with registry entries.

Sometimes, the impossible can become possible, if you're awesome!

right

I just like the redirect better Smiling
I think its safer/better/faster.

But if there is no other way of doing it I will move them.

FG_HOME

Just for the record, I looked in their CVS repository and it seems like you should be able to override it with the environment variable FG_HOME. (I told Simeon in IRC.)

Doesnt work.
I run a program called fgrun.exe before. Its a tool where you can set choose Airplanes and such using in a grafical program so there is no need to do it using the commandline.
My guess is that this is causing it. I have to look further into this.

Process Explorer

Once the executable which matters is running, open up Process Explorer and have a look at its image, the Environment tab - it'll tell you what the program's environment is at the moment.

By my look at the code APPDATA should have worked - it does :: getenv("APPDATA") rather than the special ShGetFolderLocation on CSIDL_APPDATA thing - so I'm not entirely surprised that FG_HOME isn't working.

yes. Appdata is set the right way. But the fgrun.exe shows a file in which your airports are stored. That file is problem I think. Changing that path is my next objective Smiling
