Cascades Development

[vingilot]

I have somehow successfully updated my alpha and IDE, now my only issue is that when I run my app it begins to open on the alpha but fails saying could not load library libbb.so.0, I will do some digging but if anyone has thoughts?

Thanks as always.

[vingilot]

It must be something new I am missing, as the sample apps won't even run, is there documentation on things needed to make the switch? Thanks all.

Probably rebuilding with the latest SDK will be sufficient.

Things like libbb.so have been updated, so there's a libbb.so.1 now. Relinking against the new libs would be a requirement if you aren't bundling them in the app.

Hmm, rebuilding doesn't seem to work, can I accomplish this manually? Where would the needed library/reconfiguration likely be located?

Try creating a new project and copying your files in.

Hmm, strange. My beta1 app recompiles and runs fine on simulator (don't BB10 Alpha).
Create new app, import the sources (.cpp .hpp and .qml) and rearrange the new bar-descriptor file.

I'll do that and maybe ill try it on the simulator, I've just been working with the alpha so far

I also had issues when upgrading to BETA 2.

My app would compile fine but when run in the simulator, it would crash stating: "ERROR CODE 8".

What I did is create a new Cascades application and just simply copied over the old files into my new project (with a name change here and there).

This rectified the issue.

Yes i did the same, it is unfortunate it is not backwards compatible but the issue is easily rectified, thanks all.

For error code 8, see: http://supportforums.blackberry.com/t5/Native-Development/Use-simulator-in-QT-creator/m-p/1823253#M5...

Creating a new project and copying the files is overkill but will get you past some issues.  You might just need to change your library names as described in the last section of:
