Compatibility with Qt 5.12 about googlemaps HOT 10 CLOSED

So I guess something changed on the debug side, on how plugins are loaded (at least from QT 5.10.1 to 5.12.0), it used to permit a "_debug" suffix on the plugin library name. I rename to remove suffix, and it works for 5.10.1 and 5.12.0.

All good, thanks again.

hi @dlautz314
can you please post any build logs of the errors you are seeing?

edit: should have read your message properly.
can you post a screenshot or explain what you are seeing?

from googlemaps.

Ok, not much to look at so I am showing screenshot comparison of plugin running on QT 5.10.1 vs. QT 5.12.0 (macOS - High Sierra), same map coordinates.

ON QT 5.10.1 :

ON QT 5.12.0 :

from googlemaps.

just had a look the project where we are using this plugin.
so we are at 5.12 on macos and nobody has reported map plugin issues yet.

this tells me that the problem might be only on your side (for now).

some things you can try is enabling debugging rules:
https://doc.qt.io/qt-5/qloggingcategory.html

this page outlines the usage of the QT_LOGGING_RULES environment variable.

e.g.
QT_LOGGING_RULES=qt.positioning.*=true

if this gives no hints i would debug the plugin itself by adding some qDebug() calls and see if we have a failure point where an error is ignored transparently.

there is also the guide on QML debugging:
https://doc.qt.io/qtcreator/creator-debugging-qml.html#setting-up-qml-debugging

from googlemaps.

Ok, will do.

But as I said in my original post, all the standard QT plugins work fine (i.e. osm, esri, etc.). Simply substituted the googlemaps plugin (which is using an API key).

Thanks.

Well, nothing is being logged because as far as I can tell the plugin is not being loaded. As I said before, with the logging rules enabled, I do see logging for the other plugins (i.e. osm). I have also confirmed the googlemaps plugin is present in the plugins path in the app bundle.

I am not familiar with the plugin entry point, is there a key method I should insert a qDebug() to determine it is being loaded properly?

At the moment, I am doubting this is my issue as the build and bundle is exactly the same for QT 5.10.1, and this works fine. I'll try to build one of the QT examples (i.e. minimal map) using the googlemaps plugin, see if that works.

Hi

just checked on Linux with 5.12.1 - everything works just fine
did you made install step?

from googlemaps.

Well, I'm on macOS, and the project file builds and installs the plugin correctly I believe (same place when building against Qt 5.10.1):

.../MyApp.app/Contents/PlugIns/geoservices/libqtgeoservices_googlemaps_debug.dylib

Ok, I set QT_DEBUG_PLUGINS=1, and confirmed the plugin is not being loaded, even though it's installed in the same path as the other plugins in the bundle location above.

So just trying to determine if I'm doing something wrong, just what that is?

from googlemaps.

1. try to install to Qt's install first
2. what if rename libqtgeoservices_googlemaps_debug.dylib to libqtgeoservices_googlemaps.dylib ? or make release builds and check
3. How you setup your extra plugins folder? qt.conf?

from googlemaps.

Ok, very odd, when I renamed the plugin (your step 2.), it was able to load correctly, and it now works.

Not sure why this naming is required, when it works fine for Qt 5.10.1. Any ideas or suggestions?

I can pursue with QT support, and investigate on my own from here. Your plugin is working fine from my tests, thanks for your help.

NOTE: I am running this initially in QT Creator, so I am wondering if there is an issue there?
