Re: [Qgis-user] raster calculator - no file produced
This is already fixed (tested on master) and backported to 2.8. https://github.com/qgis/QGIS/commit/0ccc07af0eacd56986fbf01418aa6d3a701e231e Thanks Jurgen!

Re: [Qgis-user] raster calculator - no file produced
Hi Claas and Jurgen, I just tested with a simple expression dem_srtm_pttm06_80m@1 * 2 and I can confirm that there is no result, both on 2.8 and 2.9 (master). Same expression, on the same machine (Xubuntu 12.04 32bits), with QGIS 2.4 and 2.6, Raster calculator works as expected.

[Qgis-user] raster calculator - no file produced
Hello, I've just installed QGIS 2.8 and noticed that the raster calculator writes any files on Ubuntu 12.04. The formula you typed was valid. The following error message is displayed in the console: Warning: QFileInfo :: AbsolutePath: Constructed with empty filename Has anyone seen something similar?

Re: [Qgis-user] raster calculator - no file produced
I also get this error message Warning: QFileInfo :: AbsolutePath: Constructed with empty filename when I double click in the Raster band to add the raster to Raster calculator expression. After that, I don't get any other error, but I also don't get any result. Best regards, Pedro 2015-02-22 21:31 GMT+00:00 Anita Graser anitagra...@gmx.at: On Sun, 22.
