(Signal Server GUI Prolem) Sorry for posting here, trying to reach you.

[alphafox02]

In the past I've included Signal Server GUI/Signal Server in DragonOS. Today I found your repo that has some great updates, to include a built in map. The problem I'm having, after switching to your submodule Signal Server and your Signal Server GUI, is that trying to regenerate one of the database example plots results in SDF not found.

For example, the first plot in the list comes back with this in debug mode. I'm not sure where the -1 is coming from. I would absolutely love to update DragonOS and include your version as you have a built in open street map option and all, I'm just trying to understand why I'm having the below problem happen that is not happening when using two other repos.

Your Signal Server GUI repo did not allow for tickets to be created.

I have updated the readme file a little bit and included some info about the elevation-data

[alphafox02]

Thank you. I’ll give it a try this evening. I did test the docker setup as well, ran into an issue where I had to build the docker without the Docker file specifying the db directory and left it to just the yaml, but I’m away from the computer and do not have my notes. I’ll try native and also docker again. Seems like great additions you’ve added!

[alphafox02]

Updated to your latest, just some observations.

Git submodule init
Git submodule update (fails as it can't find the commit)

So I git cloned direct your Signal Server repo. I went into src and mkdir build/ cmake .. build. Changed the config.ini and added the /src to the line looking for Signal Server for my test.

Loaded up the test db and ran the first generate plot option. The image came back flat, so I looked at the terminal output but it was looking for 51_52_1_2 (as an example) but all the elevation file sample file names for the test plots are named like 51:52:0:1, so I just renamed them with the _ instead of the : and reran the plot. Now it's looking correct. I'll continue testing.

[alphafox02]

It could be something unique to the test plots, especially a few of them, but with the changes you made I reran the test plot from before. Now I can trigger a segmentation fault.

I then ran the command on it's own, so perhaps it's changes that were made to Signal Server?

I looked on my other PC from past runs of Signal Server GUI/Signal Server and my .sdf files are in the 51:52:0:1 format. I notice your 35* file names have the _ so maybe you made a change to look for that naming scheme instead?

[alphafox02]

I see your comment now on Signal Server "Since 1st Oct 2023, .sdf filenames have been reformatted to address issue #35, replacing colons with underscores to enable compatibility with Python etc."
