Qt5.12.9 - [Offline Installer](
Run the installer offline to alleviate the need to register
* Note that only the `Desktop gcc 64-bit` component is needed
Copy built libraries located in `~/Qt5.12.9/5.12.9/gcc_64/lib/` in your system.
* We recommend copying those libs towards `/usr/local/lib`, and adding this directory to your ld configuration using:
* `sudo echo "/usr/local/lib" >> /etc/ && sudo ldconfig`
* **Python3.7.10 build from source** <a name="python-source"></a>
Download [Sources](
Packages `build-essentials, zlib1g-dev` are required to build python
Build and install with this oneliner:
`./configure --enable-shared && sudo make install`
## Troubleshooting / FAQ <a name="faq-instructions"></a>
* **WINDOWS - Unrecognized Publisher**
Click `More Info -> Run Anyway`
* **WINDOWS - Graphic Bug with interleaved horizontal greenlines**
Simillar problem to [this](
This occurs on Windows with NVIDIA Optimus mobile (Laptops) graphic cards.
- Update you Drivers (Use NVIDIA Geforce Experience)
- Select `High-performance NVIDIA processor` in NVIDIA control panel / Manage 3d settings / Preferred graphics processor
* **UBUNTU - Cannot find Qt Packages "unable to locate package qt5-default"**
Qt is [community software](, Uncomment / add the `universe` ubuntu PPA in your `/etc/apt/sources.list`
Example: `deb focal universe`
* **UBUNTU - There is no application installed for "shared library" files**
This is a Nautilus configuration bug on Ubuntu, just launch via terminal using `./LidarView`
* **UBUNTU - QT Offline Installer asks for registration**
Disconnect your internet connection before starting the installer, registration will not be needed
