So, my Windows laptop went belly up a couple weeks ago, and I've been working on getting things setup on it again.  The good news is that I'm now able to debug the flight software in Eclipse, which I had never gotten working before!  The bad news is that no matter what I do I can't get a GCS that I build that will run without errors.

The problem that I'm seeing is the following:

Cannot load plugin because dependency failed to load: ScopeGadget(1.0.0)
Reason: C:/swl/OpenPilot/Source/build/ground/openpilotgcs/lib/openpilotgcs/plugins/OpenPilot/ScopeGadget.dll: Cannot load library C:/swl/OpenPilot/Source/build/ground/openpilotgcs/lib/openpilotgcs/plugins/OpenPilot/ScopeGadget.dll: Invalid access to memory location.

There also appears to be a problem with the LoggingGadget with (oddly enough) the same error message.

I've tried building and re-building.  I went back through the installation of QT, SDL, etc, and still got the same result.  I even tried building in QtCreator with the same result.  I'm thinking it's a dll dependency problem, but I don't know what would be different now from my previous build.

Any ideas what the problem might be, or what i might try to diagnose the problem.  I've tried a dependency walker, but to no avail.  The laptop is Windows 7 64 bit, which is the same as it was previously.

Try deleting your GCS config file.

Thanks, but I already tried that.

What version are you building?

I've tried multiple version, and they all show the same problem.  Currently on on one of Corvus's branches from next (the UAVTalkBus branch).  Because it happens with multiple versions, and because it is the same not matter how I build it, it seems like it must be something "special" about my computer, but I can't think if what...

Upgraded Qt to 4.7.4 and I'm getting this problem too.

Woohoo!  I'm not alone anymore!

The even better news is Jose can fix *anything*

This Is exact same thing I get with 4.8.0

[dankers]

Ah, OK, I have asked Bani to look at it, I hope he finds sometime.

4.8 SDK must be close as well. Another question would be, did we try the latest qwt 6.0.1 yet? I think you tried it Sami? Maybe it is this lib and there is a fix in their trunk:
svn co https://qwt.svn.sour...ranches/qwt-6.0

[PT_Dreamer]

Ok, the explanation is simple, the trolls took the "enable-auto-import" flag from QMAKE_LFLAGS. I'll look at the best way to deal with this, maybe updating the Qwt lib in the process and borking the GCS for all other platforms but windows.
In the meantime the guys just need to edit their qmake.conf file if they want.

[Sambas]

check sambas/qwt_6.0.1_upgrade branch that I made some time ago

[PT_Dreamer]

Ok I pushed a fix to "next" and Samba's branch.

@Sambas - since it is your branch maybe you can start a review so we can have an upgraded Qwt lib on our builds.

Please do this Sambas, there are some bug fixes in the 6.0.1 release.

Worked for me.  I have scopes again!

Thanks!

Thanks?? I'm the potato man, I now want American fries!

[dankers]

For the fries award you need to help me with the UI and your framework

[PT_Dreamer]

Mmmm, thought fries were "fried potatoes", I guess I did it again.

[dankers]

Fries Award

Very different from the Potato award, much much different.

[Sambas]

Awesome potatoes.
