[Qgis-developer] HELP!! DLL not found when importing qgis.core and qgis.gui

[motta.luiz at gmail.com]

Angelica,

I make the plugin for QGis, before, it is a python program used PyQT4 and binding GDAL.

For test and debug by IDE PyScripter, i call the same package alone, i.e, out of QGis.
The same sources i copy and put out of folder for plugin´s and run the main python file (_run_OUT_QGis.py).

You can ready the source and make adaptations for your work.

The plugin´s is 'Image Boundary' in 'http://pyqgis.org/repo/contributed'

The _run_OUT_QGis.py:
------------
import sys

from PyQt4 import QtGui

from imgboundary_dlg import ImgBoundaryDialog

app = QtGui.QApplication(sys.argv)

dlg = ImgBoundaryDialog()
dlg.show()


sys.exit(app.exec_())
------------ 


Good luck!

Everything used to work fine in my PyQt4 and PyWin32 installation. Last night I installed the binaries of QGIS 1.0, then added the recommended environment variables (PATH, PYTHONPATH, QGISHOME) to my system, and now this is what my Pythonwin editor complaints about:

Also seems to be the exact same DLL what is missing in both cases (PyQt and QGIS imports). Could someone give me a hand with this? I'M STUCKED!!! If you happen to know which is the missing DLL, could you please email it to me along with the location?
