ERROR: no flowchart_file provided! Segmentation fault & Number of attributes not equal to number of geometries

[Chengzhi16]

Hi,

Thanks for sharing the tool, When I try to run the command and test data I'm getting an error that I don't quite understand.

I'm using Ubuntu 22.04, downloaded the lastest version of geoflow-bundle;
I've installed geoflow-bundle from source using cmake (using the instructions in the README file). It seems to have succeeded.

In short: 1. cannot find .json files; 2. Number of attributes not equal to number of geometries; 3. Reinstall encounter new error.

Question1: no flowchart_file provided! Segmentation fault
I use the following command:
geof flowchart.json
The output is:

ERROR: no flowchart_file provided!
Segmentation fault

And I also run other command, like:

 geof single/reconstruct.json

 lod22-reconstruct --list-plugins

The output are:

Automatically loading flowchart /usr/local/share/geoflow/gfc-brecon/single/reconstruct.json
/usr/local/bin/lod22-reconstruct: line 3:  5492 Segmentation fault      /usr/local/bin/geof /usr/local/share/geoflow/gfc-brecon/single/reconstruct.json "$@"

ERROR: no such flowchart_file: single/reconstruct.json
Segmentation fault

Question2: Number of attributes not equal to number of geometries
When I follow the command to run lod22 reconstruction:

lod22-reconstruct \
  --input_footprint=test-data/wippolder.gpkg \
  --input_pointcloud=test-data/wippolder.las \
>

And I checked the output obj file, it only generated 1 buildings.

Question3: New error when I reinstall
I remove the install files in Linux and reinstall geoflow, but new error shows when I run lod22-reconstruction command:

WARNING: no payload for LASF_Projection VLR with record_id 2112.
/usr/local/bin/lod22-reconstruct: line 3:  5736 Segmentation fault      /usr/local/bin/geof /usr/local/share/geoflow/gfc-brecon/single/reconstruct.json "$@"

Before I post this new issue I read the previous issues like #14 , ldd gfp_gdal.so seems good and the installation steps are fine as well. So I have no idea how to fix these...

P.S. during the first I tried to build, I adapted a little bit in order to fix the error I had:

geoflow-bundle/plugins/gfp-basic3d/nodes_cityjson.cpp:672:57: error: ambiguous overload for ‘operator[]’ (operand types are ‘nlohmann::basic_json<>::value_type’ {aka ‘nlohmann::basic_json<>’} and ‘nlohmann::basic_json<>’)
  672 |             std::string optilod = feature["CityObjects"][ ref ] ["attributes"]["optimal_lod"];
      |                                                         ^

then adapted this line in nodes_cityjson.cpp to:
std::string optilod = feature["CityObjects"].find(ref).value()["attributes"]["optimal_lod"];

After this adaption, no error occurs during the build process.

Thanks for your attention in advance! Help wanted!
