should produce some kind of debug info. If not, then the backend is<br>
not even being loaded. That could be caused by incorrect<br>
configuration, incorrect build-time arguments, or missing libraries at<br>
build time. Why did you build from source?<br>
<br></blockquote><div><br>I built it from source since the "vainilla" packages from F15 just produced the same result and wanted to find out if testing the latest version could bring some improvement.<br><br>I built my packages as RPM using the F15 packages as a basis. I've never done something like that before, so it's possible that I have made a mistake. But the scanner does not get detected wether I use my custom built rpms or F15's.<br>
