Re: [SailfishDevel] Boosted process (pid=721) was terminated due to signal 11: SOLVED
Good to know you found the problem.
I could have been a bit more explicit, your solution is basically what
I had to do as well. It is better to check for pointers being valid
before using anyway!
I suppose the user can disable GPS to save battery, and not all
positionInfoSources may be available on all devices.
Regards, I will have a slice of cake as well. :)

Re: [SailfishDevel] Boosted process (pid=721) was terminated due to signal 11: SOLVED
Ciao Luciano
I have cracked it!
I should have read the QtCreator Debug output more closely.
Using a constructor based on yours, I get:
[D] SatInfoSource::SatInfoSource:18 - No satellite info source available
as the demo starts up.
The problem occurs when myGeoSatelliteInfoSource->startUpdates() is
called without a satellite info source being available.
However if I check for that with an if{} (as below), then the app no
longer crashes.
void SatInfoSource::startUpdates() {
if (myGeoSatelliteInfoSource) {
myGeoSatelliteInfoSource->startUpdates();
}
else {
qDebug() << "Start Updates requested, but no position info
source available";
}
}
Me thinks time for a piece of Christmas Cake.

Re: [SailfishDevel] Boosted process (pid=721) was terminated due to signal 11
Curiouser and curiouser. Today the app still exits on GPS Startup, but
the Signal 11 error is not being reported, even though this was
repeatedly the case last night.
In the meantime I have created a throwaway demo SatInfoSourceDemo
illustrating the problem. (Basically the standard Sailfish template, +
satinfosource.h and .cpp)
The app exits as soon as satInfoSource.startUpdates(); is called. (In
this demo from the Pulley Menu on FirstPage.qml
I am guessing the problem is either in my satinfocource plugin, or
more likely in the Qt5Positioning Library this is calling. The
Harmattan equivalent of htis code works on a real N9.

[SailfishDevel] Boosted process (pid=721) was terminated due to signal 11
Hi All My application quits unexpectedly during startup, apparently due to "signal 11". This seems to be caused by turning the GPS on, as the error occurs immediately after the app does that. I experience this on the Emulator, so it maybe down to the Emulator not having a real GPS. (my Jolla phone is currently in transit between Vantaa and Zurich according to Fedex).
