Hi William and Sergio, <br>I don't have a Mac, so could you do further tests?<br><br>Try to set the path to your GDAL python mods in the "path to GDAL binaries", <br>then exec a python tool from the Raster menu, e.g. polygonize or merge.<br>
AFAIK on OSX the path to python mods should be similar to <br>/Library/Frameworks/GDAL.framework/Versions/1.7/Python/<br><br>Does it work now? If no, restart QGis and to execute the tool again.<br>What's the test result?<br>
<br>Cheers.<br><br><div class="gmail_quote">On Tue, Sep 28, 2010 at 6:53 PM, William Kyngesburye <span dir="ltr"><<a href="mailto:woklist@kyngchaos.com">woklist@kyngchaos.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
That works. What I'm saying is that as run from Qgis the GDAL python scripts are not getting an environment.<br>
<br>
It's possibly because of the way OS X applications (as opposed to shell programs) operate - they get nothing from the shell environment, so it makes sense that other programs (even shell programs) started from an application also get no environment.<br>
<br>
Maybe GDAL tools needs a PATH (at least for Python) setting? There is a "pymod path" in the settings, but it's currently disabled, and I don't know if that's the right option.<br>
<br>
Or Qgis needs to try to get environment from a Terminal somehow for use by helper programs?<br>
