Native Development

[allan175]

We have our development system set up to build/install from the command line (in Linux).

Playbook development is fine *but* the apps produced crash on a BB10 Dev Alpha device, the strange thing is that they run some code before crashing but the crash occurs before main is reached. It seems to be in the pre-main construction of the globally scoped objects. It mentions an offset from getFacet when it dies with a segmentation violation.

Any idea what differences between Playbook/BB10 would cause this?

Replying to my own post, but I finally found the problem!

It turns out that the BB10's version of libstdc++.so.6 was killing the app before it reached main().

My solution was to include the NDK version of the library in my bar-descriptor.xml:-

  <asset path="../bbndk-2.1.0/target/qnx6/armle-v7/lib/libstdc++.so.6" type="Qnx/Elf">lib/libstdc++.so.6</asset>

and, to make sure it uses this file:-

  <env var="LD_LIBRARY_PATH" value="app/native/lib"/>

Now the BAR file works fine on both Playbook and BB10.

Hoepfully this might help someone else!
