Re: i.atcorr with Sentinel2

Thanks Markus for the hint, and many thanks Sajid for your continuous support!

Now, I compiled both GRASS 7.4 and 7.5 on Ubuntu 14.04 (gcc (Ubuntu 4.8.4-2ubuntu1~14.04.1) 4.8.4).
I configured with the parameters Sajid sent and dropped all optimisation flags.
However, the result is still the same for both versions: Only NULL cells from i.atcorr with Sentinel-2

On my Ubuntu 16.04 box I only have a package-install from UbunutGIS experimental, which also fails.
To test a completely different system I also tested GRASS 7.5 (daily) and 7.4.0RC1 on OSGeo4W. Both fail as well.

For completeness: I could not get Sajids data to work for me either.

Sajid, which code revision are you using? Maybe a change somewhere else interferes?
Or would you mind trying the release candidate?

Cheers
Stefan

How did you compile the version? Perhaps a compiler optimization is creating troubles?
Which operating system, which compiler, etc?
