Hello, Jurgen,
In Windows QGIS.bat, it has also got the same content.
@echo offcall "%~dp0\o4w_env.bat"@echo offpath
%OSGEO4W_ROOT%\apps\qgis\bin;%PATH%set
QGIS_PREFIX_PATH=%OSGEO4W_ROOT:\=/%/apps/qgisset GDAL_FILENAME_IS_UTF8=YESrem
Set VSI cache to be used as buffer, see #6448set VSI_CACHE=TRUEset
VSI_CACHE_SIZE=1000000set
QT_PLUGIN_PATH=%OSGEO4W_ROOT%\apps\qgis\qtplugins;%OSGEO4W_ROOT%\apps\qt4\pluginsstart
"QGIS" /B "%OSGEO4W_ROOT%"\bin\qgis-bin.exe %*
But, I do not know how to use this information in Python, to set runtime path.
Regards.
David

In OSGeo4W there is a batch file python-qgis.bat you can pass your script to:
@echo off
call "%~dp0\o4w_env.bat"
@echo off
path %OSGEO4W_ROOT%\apps\qgis\bin;%PATH%
set QGIS_PREFIX_PATH=%OSGEO4W_ROOT:\=/%/apps/qgis
set GDAL_FILENAME_IS_UTF8=YES
rem Set VSI cache to be used as buffer, see #6448
set VSI_CACHE=TRUE
set VSI_CACHE_SIZE=1000000
set
QT_PLUGIN_PATH=%OSGEO4W_ROOT%\apps\qgis\qtplugins;%OSGEO4W_ROOT%\apps\qt4\plugins
set PYTHONPATH=%OSGEO4W_ROOT%\apps\qgis\python;%PYTHONPATH%
"%OSGEO4W_ROOT%"\bin\python.exe %*
PYTHONPATH and QGIS_PREFIX_PATH are most important.
Jürgen
