cannot locate libqgis_core and libqgis_gui

[3nids]

I cannot find the libraries core and gui installed anywhere.

ls /usr/local/Cellar/qgis3-dev/2.99/QGIS.app/Contents/MacOS/lib/

libqgis_app.2.99.0.dylib
libqgis_server.2.99.0.dylib
libqgispython.2.99.0.dylib
qgis
libqgis_app.dylib
libqgis_server.dylib
libqgispython.dylib

It's the same if manually built or in 2.18 package.
I tried to play with QGIS_MACAPP_BUNDLE without success.

Is this because of static linking?

Hi Denis,

The main API libraries qgis_core, qgis_gui and qgis_native (and qgisgrass7) are built as frameworks instead of dynamic libs:

/usr/local/opt/qgis3-dev/QGIS.app/Contents/Frameworks/

Not sure if the other .dylibs should be converted to frameworks as well. There are pros/cons.

I am currently working on a new QGIS_MACAPP_BUNDLE that is truly minimal bundling, i.e. no *qgis* libs are bundled, but referenced from installed prefix locations. This allows for other custom C++ apps to find the libs/frameworks appropriately.

Hi Larry,
Thanks for the prompt feedback.
The context is to try to build QField on the mac and I need to add qgis_core library.
Is this feasible with the frameworks or I would have to wait for your new bundle?
Cheers!

Hi Denis,

If you can give more feedback on how you are intending to link to the frameworks, i.e. just for building and testing, or for distribution packaging, that would help determine what may work for you right now. Using the already-bundled frameworks may be advantageous or not depending upon your needs.

You can contact me directly via my QGIS Dev mailing list email address, if needed.

Hi Larry,

I am trying to compile QField in Mac.
It needs QGIS core to build: https://github.com/opengisch/QField/blob/master/qgis.pri#L8-L9

@m-kuhn pointed me to Qt doc on using frameworks. But I had no luck trying:

QMAKE_LFLAGS += -F /Users/denis/opt/qgis/QGIS_INSTALL/QGIS.app/Contents/Frameworks/
LIBS += -framework qgis_core.framework

Do you have any hint regarding this?
Thanks again for your time,
Denis
