[osgeo4w-dev] QGIS failed to start because QT platform plugin

[Pedro Venâncio]

Hi Jurgen,

Thanks for the feedback!

The strange thing is that it only happens when starting QGIS thru
qgis-rel-dev-g7.bat or qgis-ltr-dev-g7.bat (with GRASS). And if I change
the line

start "QGIS" /B "%OSGEO4W_ROOT%\bin\qgis-rel-dev-bin-g7.exe" %*
to
start "QGIS" /B "%OSGEO4W_ROOT%\bin\qgis-rel-dev-bin.exe" %*

it already starts QGIS as expected.

I've also removed all OSGeo4W folder and installed again, but the behaviour
is the same.

Thanks Jurgen!

Best regards,
Pedro
