I'm doing some minor tweaks to the source code of energyplus for a project (for the first time), and I've made the edits and compiled it successfully, but when I test it out on a project I get a **FATAL:Errors occurred on processing input file. Preceding condition(s) cause termination. The problem is, no error file seems to have been created so I can't track down if it's an issue with my source code edits (probably), or potentially something to do with the fact that I tested the model in 9.1 but now I've used the code from 9.2 as a starting point. Is there some other place than my local project directory that an error file might be stored, or some other way to get more details from the command line?

Full error:

EnergyPlus Starting
EnergyPlus, Version 9.2.0-44e30c353a, YMD=2019.12.10 10:01
**FATAL:Errors occurred on processing input file. Preceding condition(s) cause termination.

It would help if you specified what you modified and how you executed EnergyPlus. Otherwise it's hard to give answers that aren't fairly speculative.

I'm adding a few output variables for the refrigeration systems, in particular psuction for the compressors as a test. I've pulled that variable out of the loop it was calculated in and added it to an output. However I'm not asking what my specific problem is, I'm just asking why there is no error file being produced in the usual location.

Well, it's best not to assume a file was written. Depending upon what has been changed, it's possible that something went wrong early enough that no file was written. It isn't clear from your question whether E+ finished successfully or not. So there's that. Assuming it did write a file, then how it was run should determine where the file is.

No it didn't even start, based on the fatal error on processing the input file. What other information would be helpful, other than posting the entire code I've changed? I'm just confused because the error seems to indicate that E+ thinks something is wrong with the input file, but that's all the information I was given.

I figured it out - kind of silly on my part. First, my model was made in 9.1, and I was using 9.2 (intentionally) for my work. If I ran that file through the 9.2 release version, it gave me a very useful error and said the file was the wrong version. However in the test build I'm working on, that didn't show anywhere. So I just updated the file and now all is good and running.

In addition to that, when I ran the model (through the command line interface) I specified where the input file was, expecting the resulting simulation files to also be saved there, but then noticed that they are actually being saved to the release/Products folder (current directory) because I didn't specify an outputs folder.

Regarding your second point, that's always the case, local build or official release alike. So instead of going to <build>/Products and running energyplus <path/to/my.idf>, perhaps consider doing the opposite (cd next to your idf file, and do <build>/Products/energyplus my.idf). You could use an alias / env variable to shorten your path to your locally built energyplus (or add it to PATH) if that gets annoying to type)

Yes, that's a better way to do it, to avoid having to specify the output path. It's just been a while since I've runt through the command line and I guess eplaunch has made be lazy.
