Need help with "Undefined symbol" error

[mikets]

Hmm, that's interesting. We are using the 2010 DVD. Let me make sure I understand, you are saying the cRIO image is correct but the WPILib I was linking in the WindRiver Workbench is somehow old? Is there a way to tell for sure? The WindRiver Workbench I have installed is version 3.0.1 with Build id: 20080514-1211. Hmm, if 20080514 was the date, that's very old as you said. But how can this be? It's coming from the 2010 DVD. I will uninstall it and clean re-install it again to make sure.

BTW, I assume you are referring to WorkbenchUpdate20100107.exe from http://www.usfirst.org/frccontrolsystem

If so, I ran it again and it still said my Workbench version is 3.0.1.

did you install windriver to a directory other then the default?

[mikets]

No, it is installed to the default directory c:\WindRiver.

After clean re-installing WindRiver and reappling all the updates, I am finally able to download code to the robot without any complains. WindRiver is still showing v3.0.1. So I suppose this is the correct version. I assume either I missed one of the updates or somehow it did not take previously. Thank you for all the info.

I'm sure about the WPILib that you are linking against (based on your symbols). I can't say for sure that your image is correct, but I can say it doesn't match. The driver station should be able to tell you if the image is correct when looking on the Diagnostics tab.

The build ID is from the WindRiver tools, so the date is not surprising.

Can you look at C:\WindRiver\vxworks-6.3\target\lib\WPILib.a and check the file date. That will give us an idea since that's the default location to link from.

The reinstall from the DVD should not be necessary.

That is the update I'm referring to. Just to make sure, open the update as a zip file and extract the files into your windriver directory. I've heard grumblings that the self-extracting zip installer is failing to copy in some cases.

Don't expect that version number to change. That's the version of the tool from WindRiver, not the update version.

Here is the info you are asking for. But of course since it is working now, it is obviously the correct one. Unfortunately, I should have captured that before my clean re-install. But my student should still have this problem and hoepfully he hasn't reinstalled yet. I will ask him to send me his file date.
