segfault in tutorial raster example about fmi HOT 9 CLOSED

It appears to be a problem in rgdal or in some other library. Maybe you could contact the rgdal maintainer directly. See the contact details here: http://cran.r-project.org/web/packages/rgdal/index.html.

Hi!

I do not know if you were able to solve this already, but I am facing exactly the same problem. GDAL is somehow broken, when it comes to handling grib2 -format files. Try getting your data in grib1 -format, and you might have better luck. I am running up-to-date Fedora 21 and 20, and grib2 fails in both of them. At least in Fedora 20, grib1 format is better supported.

@esaostring what is your GDAL version? Have you tried the latest?

from fmi.

@statguy my GDAL versions, resulting core dump:
First, Fedora 20, up-to-date, causing core dump:
Second: OpenSuSE 13.1, (maybe) not up-to-date (I'm afraid to update it due to GDAL problems), working
Third: CentOS7, up-to-date, causing core dump:

[Fedora 20]$ gdalinfo --version
GDAL 1.10.1, released 2013/08/26
[Fedora 20]$ gdalinfo input/ennuste.grib2

There is also a Fedora 21 installation (up to date), with gdal version 1.11.2, and that core dumps also.

By latest you mean 2.0 something, or that latest update found in distributions 1.11.2?

I would not totally blame gdal, but some related libraries perhaps, since OpenSuSE (works) and Fedora 20 (fails) have the same gdal version number.

Are you familiar with the Linux debugging tools, or want to read some tutorial? You may try to find where it segfaults. Anyway, as you seem to have the latest 1.*, you may also report the problem to GDAL maintainer.

Yes, somewhat familiar. I might proceed with the bug report early next week. Thanks.

from fmi.

Ok thank you. Please keep us updated :)

from fmi.

Bug reported.

from fmi.

Problem seemed to be Fedora-specific and potentially fixed now, closing this issue.
