<br>
Hi Francesco,<div>are you using osgeo4w? In that case I suggest you to have a look to the startup .bat files (like C:\OSGeo4W\OSGeo4W.bat), that setup the right evnironment (python pat, bin dires, etc.)</div><div><br></div>
<div>In general you have to add the various Qt and Qgis DLLs to the PATH, and configure the python paths to be able to peak the qgis modules. </div><div><br></div><div>giovanni<br><br><div class="gmail_quote">2012/5/24 <a href="mailto:francescoboccacci@libero.it" target="_blank">francescoboccacci@libero.it</a> <span dir="ltr"><<a href="mailto:francescoboccacci@libero.it" target="_blank">francescoboccacci@libero.it</a>></span><br>
