[Qgis-developer] QGIS 0.9 on windows:QgsApplication.setPrefixPath() has an invalid type

[Aaron Racicot]

Hi there Jesse,

Can you try to just hit this function from the command line like:

aaronr at z-linux2:~/work/$ python
Python 2.4.4c1 (#2, Oct 11 2006, 21:51:02)
[GCC 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from qgis.core import *
>>> str(QgsApplication.prefixPath())
''
>>> QgsApplication.setPrefixPath("/usr/local",True)
>>> str(QgsApplication.prefixPath())
'/usr/local'
>>>

This will let us know if things are at least working in theory and we can
track down why it is not working in your case.

Subject: [Qgis-developer] QGIS 0.9 on windows:QgsApplication.setPrefixPath()
has an invalid type

When attempting to run the \2_basic_main_window\mainwindow.py script from
the tutorials available here:
http://mapserver.sk/~wonder/qgis/tutorials.tar.gz

I receive this error:

Traceback (most recent call last):
  File "mainwindow.py", line 110, in <module>
    main(sys.argv)
  File "mainwindow.py", line 94, in main
    QgsApplication.setPrefixPath(qgis_prefix, True)
TypeError: argument 1 of QgsApplication.setPrefixPath() has an invalid type

Looking here
(http://svn.qgis.org/api_doc/html/classQgsApplication.html#4f540de6bcbc9ec14
dcf0499a9371c42) it would appear that a string is expected, which is what
the mainwindow.py script above passes.

Any ideas on solving this?

Thanks in advance
