Yes, I could do a local build of cmake, but decided to switch from centos to ubuntu (18.04, not 16 - unity is an abomination).

Well, I bit the bullet, but I think it put it in my mouth backwards :-)

By default CentOS 7.5 comes with cmake xx.xxx.xx.xx, but HDF5 requires 3.1.0

Off on my next adventure.

Decided I'd try and build it all, since I may want to do more than l2gen later.CentOS 7.5Figured I probably didn't need to do any of the 3rd party stuff so jumped right to Create build directory and run cmake CMake allows for out-of-source-tree builds. Make a directory for this and run cmake...

There are plenty of discussions on the methods and pitfalls to recompile/rebuild "all" of SeaDAS.  Suppose I only want to recompile one image (l2gen in my case).  What steps are needed to do that?

Thanks!

You're right, it seems wrong, but it works!
Thanks!

PS.  Latest version Seadas, CentOS 7 updated last week,

bcb@modis ~]$ java -version
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

(this is similar to, but different than https://oceancolor.gsfc.nasa.gov/forum/oceancolor/topic_show.pl?tid=8223)Are there limited file types that gpt.sh subset can read?  I'm attempting to, at this point, create "pretty pictures" from l3m files usinggpt.sh subset.xml -Ssource=A20...

those are all warnings and shouldn't cause the 'error 2' (as far as I know).  Is there a real error earlier that you missed?

Yes, it might be interesting, bu I have a solution that works for me, so it's "solved" from my perspective.

I find this "behavior" occurring between 30 and 50% of the time.  I'll stick with --refreshDB to avoid having to process twice to get the best results...
