Hi all, <br><br>if I run the following code from a terminal:<br><br>brushtyler@Joe-Notebook:~$ python<br>>>> from qgis.core import *<br>>>> QgsApplication.setPrefixPath('/usr/local/qgis/', True)<br>
>>> QgsApplication.initQgis()<br><br>I get<br><br>/home/brushtyler/projects/sources/qgis/src/core/qgsproviderregistry.cpp: 84: (QgsProviderRegistry) Checking /usr/local/qgis//lib/qgis/plugins for provider plugins<br>
/home/brushtyler/projects/sources/qgis/src/core/qgsmessageoutput.cpp: 65: (showMessage) No Data Providers:<br>/home/brushtyler/projects/sources/qgis/src/core/qgsmessageoutput.cpp: 69: (showMessage) No QGIS data provider plugins found in:<br>
/usr/local/qgis//lib/qgis/plugins<br>No vector layers can be loaded. Check your QGIS installation<br><br>As far as you can see, the QgsApplication searches providers in <br>/usr/local/qgis//lib/qgis/plugins<br>but in my local installation the qgis providers are in <br>
/usr/local/lib/qgis/plugins<br><br>So just changing the code above to <br><br>>>> from qgis.core import *<br>
>>> QgsApplication.setPrefixPath('/usr/local/', True)<br>
>>> QgsApplication.initQgis()<br><br>and providers are loaded well :)<br>I hope this helps.<br><br>Cheers.<br><br><div class="gmail_quote">On Wed, Jul 6, 2011 at 1:12 PM, leonidas <span dir="ltr"><<a href="mailto:leonidas_liakos@yahoo.gr">leonidas_liakos@yahoo.gr</a>></span> wrote:<br>
