Recently, I follow [LidarView\_Developer\_Guide](https://gitlab.kitware.com/LidarView/lidarview-core/-/blob/master/Documentation/LidarView_Developer_Guide.md) to build VeloView  
It occurred some errors:

Based on the log you provided, your revision of master is based on ParaView 5.9.0, however LidarView has undergone a large software upgrade recently and I strongly recommend doind a clean build with either the latest master based on Paraview 5.9.1, or an older tag with associated Developper guide.

I can also see you are using MSVC19, but use a Qt5 designed for ‘msvc2015\_64’, did you select the right toolset prior to configuration or is this a mistake ?

Hi Arnaud,

First of all, thanks for your reply.  
I did these with “VS2015 x64 Native Tools Command Prompt” (so I don’t know why it shows the C compiler identification is MSVC 19.0.24215.1):

1. cd D:
2. git clone [https://gitlab.kitware.com/LidarView/VeloView-Velodyne.git](https://gitlab.kitware.com/LidarView/VeloView-Velodyne.git) --recurse-submodules src
3. mkdir D:\build
4. cd D:\build
5. cmake D:\src\Superbuild -GNinja -DCMAKE\_BUILD\_TYPE=Release -DUSE\_SYSTEM\_qt5=True -DQt5\_DIR=“D:/Qt5.12.9/5.12.9/msvc2015\_64/lib/cmake/Qt5”

it shows:  
– Configuring done  
– Generating done  
– Build files have been written to: D:/build  
then I did next step and some other errors occurred.

1. cmake --build . -j

Partial log display:
