Re: App for vector renderer maps, using OpenGL ES 2.0

@Zeta, thank you very much for testing!

I must say I am quite puzzled with the results. Its all working on OnePlus X SFOS 2.1.0.11 - no crashes.

So, I would like to ask others to test and check whether it works on other hardware. Earlier we had as working:

Oneplus One, SFOS 2.1.1.24
Jolla C, SFOS 2.1.1.26
Sony X, SFOS 2.1.1.26
Jolla Tablet, SFOS 2.1.1.26

and crashing

Jolla 1, SFOS 2.1.0.11, n=3
Photon Q, 2.1.0.11

Would be good if at least one J1 owner would confirm the crash with the current demo.

Few things have changed when compared to the earlier test:

* I am linking libstdc++ statically, as I did for mapbox-gl-qml to ensure that I can distribute Mapbox GL QML type as a plugin. Earlier, a dynamic linking with libstdc++ was used and libstdc++ together with the libgcc_s were provided with the binary. I am not doing that anymore and maybe this causes the crash.

* QMapboxGL library is updated to qt-staging branch from qt-v1.1.0 to enable mangling of URLs when requested from online (corresponding PR https://github.com/mapbox/mapbox-gl-native/pull/10156 was just accepted upstream). Use of the latest qt branch was required to enable support of internal Mapbox GL scheduler that is used in constructing the corresponding callback. URL mangling is required when you want to use servers that ask for api keys, as the server setup by @otsaloma does. However, maybe there are some additional changes in the new branch that lead to the crash.

* there are probably several other changes that I did while developing the QML type, but nothing really pops up into my mind that would cause such behavior.

So, before I start reverting the changes, would be good to get some additional testing on the current version.

Edit: PS: Zeta, sailfish_latest_armv7hl (armv8el) used to be before as well. As far as I understood, its default for the current SFOS target. Or am I wrong?

Re: App for vector renderer maps, using OpenGL ES 2.0

For me mapbox-sfos is working fine on nexus 5 with 2.1.2.3.

bomo, thanks four reporting ! it's the latest version (red map with country borders only ), right ?

the version from the linked repo. Yes, it was red with borders only; and playing with the knobs worked also.

Yes, me too. I hope it is only something wrong on my phone, but I doubt it. We'll see when another J1 user will test it.

Searching a little, I found that : https://wiki.merproject.org/wiki/ARM

The OBS provides a number of uniquely named schedulers but these are not named appropriately for Mer and we use armv7el scheduler for armv6l, armv7l builds and armv8el scheduler for armv7hl.

So it looks like it is only a name, not something related to armv8.

No, I doubt there is something wrong with your phone. But let's wait for conformation. So far, we have 1+X and N5 working, J1 failing.

Thank you for looking it up!

Re: App for vector renderer maps, using OpenGL ES 2.0

Hi,

Your mapbox-sfos-0.1 is working perfectly on Oneplus One, with 2.1.1.24. smooth zooming while pitched in and lanscape mode: great job!

Code:

[nemo@Sailfish ~]$ mapbox-sfos

[D] unknown:0 - Using Wayland-EGL

Segmentation fault

J1 - SFOS 2.1.2.3

I noticed the GPS satelite icon in the status bar was flashing for a while after trying to launch mapbox-sfos.

Same result on my J1 - SFOS 2.1.2.3.

Re: App for vector renderer maps, using OpenGL ES 2.0

Thanks for testing!

GPS was enabled in the earlier version (version 2) of the demo, just not advertised.

Looks like we have similar situation as earlier, with J1 failing and others doing just fine. Zeta's backtrace suggests that crash is during rendering (calls to mbgl::Renderer::Impl::render), its maybe just hits the corresponding section faster.

We are still missing debug info in the builds, I'll look how to enable it so we could get something more out of the crashes. Just probably would do it a bit later. Or maybe someone could look into qmapboxgl and mapbox qml rpm's and suggest the changes?
