Processing/SAGA: Union freezes program

[qgib]

Author Name: Mattias Lindman (Mattias Lindman)
Original Redmine Issue: 14509
Affected QGIS version: 2.12.3
Redmine category:processing/saga
Assignee: Victor Olaya

---

When trying to use the Union and Intersect tools in the SAGA toolbox the following error message is given:

Can't load requested DLL: .....\gdal_MrSID.dll
127: It is not possible to find the specified procedure (translated from Swedish)

I have checked and gdal_MrSid.dll is where it should be according to the path given in the error message. The intersect tool finishes and gives a result while the Union tool does not (and the program freezes).

I have tried both QGIS 2.8.7. and 2.12.4 in Windows 8.

This due to the unfortunate situation, that saga in osgeo4w is repackaged from binaries saga ships and those contain a different version of GDAL. You can just remove that DLL if you don't need MrSID data.

Now that we know that the error message about gdal_MrSid.dll is unrelated, let's focus on the operation that does not work.

first of all, the union you are trying to do does work on native SAGA?

If yes then please attach sample data to allow us replicate the issue locally. Thanks
