[QGIS-Developer] Installing qgis custom widgets in designer from development build

[Chris Crook]

Hi all

I'm still having problems installing the custom widgets into designer on ubuntu 18.04.  I've run make  and make install, and copied the custom widgets .so with

sudo cp libqgis_customwidgets.so.3.9.0 /usr/lib/x86_64-linux-gnu/qt5/plugins/designer/libqgis_customwidgets.so

It is being found, in that when designer starts it now dies :-(  I think the problem is that it is not finding qgis.db, though there are other errors along the way.  Output when starting up is listed below.  QGIS itself starts up normally.

Still desperate for ideas!!!

Thanks
Chris

Hi Chris,

First thing is to run CMake with -DWITH_CUSTOM_WIDGETS

Then the resulting library needs to be copied into the folder where Qt
loads its plugins from.

But that doesn't seem to be built as part of the CMake build (can't find the file anywhere), and the only reference to it I can find is in the debian directory as a package.  I'm not familiar enough with packaging to figure out how it gets built or what source files are used :-(
