=> demout.tif ok

link external raster via gdal

r.external --verbose input=C:\wd\testdata\demout.tif output=demext title=TestExternalLink

=> r.external-crash

I've tried the example above with wxpython- and tcltk-gui, in both cases r.external crashes

elevetation data exported as geotiff and linked with r.external => no crash of r.external

but the linked geotiff, added to the mapdisplay, is not displayed

Is this now fixed? see also #885 - please close here if #885 reports the same.

Replying to neteler:

Is this now fixed? see also #885 - please close here if #885 reports the same.

tested with the nightly build WinGRASS-6.4.SVN-r40852-1-Setup.exe on a WinXP32, displaying the linked raster in the wxgui is working. so closing this report, because #885 reports the same.
