Description

I have compiled GDAL 2.1.2 following the instructions in
[[http://www.gdal.org/drv_mdb.html]] to read hexagon/intergraph Geomedia .mdb layers. It works fine with ogrinfo and ogr2ogr.

Trying to open the attached file (three layers, one with one polygon) in qgis loads the sublayers and crash when update canvas. the stdout says:

QGIS died on signal 11[New LWP 30883]

(full text attached)

Runing qgis in gdb freezes before listing sublayers.

here are gdb output.

  • Status changed from Open to Feedback
  • Crashes QGIS or corrupts data changed from No to Yes

have you really compiled QGIS against your compiled version of gdal/ogr?

#2 Updated by amedeo fadini 11 months ago

Oops... Sorry..
I wasn't aware of the needs to recompile also QGIS and never compiled QGIS before (i use nightly repository). In fact it's logic. I'll give a try and update the issue·

#3 Updated by amedeo fadini 11 months ago

I compiled QGIS on my system, the version of GDAL matches with the version I have installed.
The crash still happens, but is only after the layer is loaded, when update canvas: if I unflag "canvas update" it loads the layer, assign sr, open attribute table and even copy geometry to other layers. All is ok. When the geomedia layer is disabled map canvas update correctly, when I enable it chrashes.
