Test: code aborted after successfully producing output

[awickert]

I installed the prereqs and compiled the software no problem with the README information -- excellent!

I then created a test case with a DEM of my favorite place as a kid:

./build/dephier.exe AWtest/BCwest.tif AWtest/testOut AWtest/testDH 0

It ran well -- all outputs look fine -- but ended with an abort:

./build/dephier.exe AWtest/BCwest.tif AWtest/testOut AWtest/testDH 0
m Processing    = AWtest/BCwest.tif
m Output prefix = AWtest/testOut
m Output graph  = AWtest/testDH
m Ocean level   = 0
m Data width  = 130
m Data height = 170
m Data cells  = 22100

Are you running the latest? My dephier.exe takes only 3 inputs and didn't crash.

[awickert]

Ignore my comments for a moment! I didn't realize that I was on my branch, which is a bit out of date. Give me ~5 minutes to update and revise/close.

[awickert]

Your version compiled and running. Updates:

1. ./build/dephier.exe <Input> <Output> <OutGraph> <Ocean Level> does not seem to work, as stated on the README. It seems that instead it is ./build/dephier.exe <Input> <Output> <Ocean Level>.

2. The output is not appearing.

3. My runs are still ending with:

double free or corruption (out)
Aborted (core dumped)

[r-barnes]

Okay, <OutGraph> should probably be removed from README.md, unless you think we should have that output in the test executable.

The following works for me:

./build/dephier.exe AWtest/BCwest.tif AWtest/testOut 0

[r-barnes]

Suggest you compile with cmake -DCMAKE_BUILD_TYPE=Debug and then run with gdb to catch the problem.

Kerry's test file; is this a library that I'm missing?

No, that's just where the code stopped. Type bt to get a backtrace and then up until you get into the DH code.

[awickert]

Highest-level error seems to be from libproj. I'm on my laptop; going to retest on desktop with newer version of Ubuntu and libraries.

[awickert]

Yes; was simply outdated gdal/proj/something. Thanks for the debugging walkthrough!

[awickert]

Closed until I realized that there remain two related and unresolved issues:

1. Exporting the DH graphs. Are we doing this? I think that it's one of the most useful pieces of information from the DH, though we could -- as you suggest -- view the executable as just a demo.
2. Indeed, no outputs seem to be written anymore, even though an input file name is required to run the DH. So this should be fixed in some way or another.

[speleophysics]

After fixing my compilation problems, I also tried running BCwest.tif. I'm getting the same behavior. Runs fine, or at least with no error messages. No output files are created.

[r-barnes]

Okay, the outputs had got dropped somehow. I've added them back. @awickert: DH graphs are output now as well.

[awickert]

Everything is now working for me, and the output graph looks good.
