Issue: Unable to Generate Valid JSONL Output – All Vertices Are Null

I encountered some issues while installing and using the Roofer tool.

Installation Issue

I am using Windows 11, and during installation, I had to use the command:

cmake --build build --config Release

instead of:

cmake --build build

When running the original command, I received the following error:

Make Error at build/apps/roofer-app/cmake_install.cmake:39 (file):
  file INSTALL cannot find "PATH/roofer/build/apps/roofer-app/Release/roofer.exe": No error.
Call Stack (most recent call first):
  build/apps/cmake_install.cmake:37 (include)
  build/cmake_install.cmake:42 (include)

Configuration Issue

After installation, I tried running the command:

roofer -c config_file

with configuration files in various formats, including:

• roofer -c config_file.txt
• roofer -c config_file.toml

The configurations used were as described in the CLI Application Documentation:

[input.footprint]
source = "PATHTOGPKG.gpkg"

[[input.pointclouds]]
name = "pointcloud"
source = "PATHTOLAZ.laz"

[output]
folder = "PATHTOOUTPUT"

I also tried the format from the FOSS4G presentation:

[input.footprint]
path = "PATHTOGPKG.gpkg"
id_attribute = "id"

[[input.pointclouds]]
name = "pointcloud"
path = "PATHTOLAZ.laz"

[reconstruction]
reconstruction_complexity = 0.7

[output]
path = "PATHTOOUTPUT"

Result Issue

Not all attempts produced an output. When there was output, it always contained:

"vertices": [[0,0,0],[0,0,0],[0,0,0],[0,0,0]]

or something similar, with all vertices being null.

Input Details
Both inputs (GPKG and pointcloud) are in EPSG:31983, and there is overlap between the two datasets. I was also unable to visualize the output with cjseqview, possibly due to the null vertices.

Could you please advise on these issues? Thank you!

Start by reproducing the Windows build with cmake --build build and the CLI runs using the documented TOML configuration formats. Check whether the installation command, configuration fields, or EPSG:31983 inputs lead to the all-zero JSONL vertices. Done means the tool installs with the documented command and produces valid, non-null output for the reported inputs.
