Installation

This guide describes the available pre-compiled library packages and instructions for manual builds from source. The BSL can be compiled cross-platform and has been tested for Linux GCC compilers and Windows MSVC 201x compilers.

The source code is published on GitHub .

Dependencies

The BSL uses Protocol Buffers as an encoding protocol for network communication, configuration requests, and file recordings. The protocol allows cross-platform, versioned by design, structured, and optimized data transfers.

It is recommended to install a Protobuf version 3.6.1+ on the build system, as the BSL provides configuration and stream methods directly as Protobuf messages. If the Protobuf dependency conflicts with the existing development environment, the standalone mode (use the CMake flag -DBF_USE_SYSTEM_PROTOBUF=OFF) of the BSL can be enabled. It offers the core functionality, such as streaming simple point clouds, but lacks configuration methods and metadata information.

Pre-compiled packages

Linux

Debian packages with full Protobuf support are available for Ubuntu 19+ and Debian 10+. Debian packages with BSL standalone mode are available for older systems.

Ubuntu 19+ and Debian 10

sudo apt update
sudo apt install -y wget libprotobuf-dev libprotobuf17
wget https://github.com/Blickfeld/blickfeld-scanner-lib/releases/latest/download/blickfeld-scanner-lib-dev-Linux.deb
sudo dpkg -i blickfeld-scanner-lib-dev-Linux.deb

Latest debian-based systems

sudo apt update
sudo apt install -y wget libprotobuf-dev libprotobuf22
wget https://github.com/Blickfeld/blickfeld-scanner-lib/releases/latest/download/blickfeld-scanner-lib-dev-testing-Linux.deb
sudo dpkg -i blickfeld-scanner-lib-dev-testing-Linux.deb

Older debian-based systems

sudo apt update
sudo apt install -y wget
wget https://github.com/Blickfeld/blickfeld-scanner-lib/releases/latest/download/blickfeld-scanner-lib-dev-standalone-Linux.deb
sudo dpkg -i blickfeld-scanner-lib-dev-standalone-Linux.deb

Python (cross-platform)

The BSL is also available as a Python package for fast prototyping. For high-performance environments it is recommended to use the C++ implementation.

pip install blickfeld_scanner

Windows

No pre-compiled binaries are currently available. Please build it from source.

Building from source

Linux

Dependencies

CMake is required as a build system.

curl https://cmake.org/files/v3.15/cmake-3.15.3-Linux-x86_64.sh -o /tmp/curl-install.sh \
    && chmod u+x /tmp/curl-install.sh \
    && sudo mkdir /usr/bin/cmake \
    && sudo /tmp/curl-install.sh --skip-license --prefix=/usr/bin/cmake \
    && rm /tmp/curl-install.sh

Install Protocol Buffers from source or install available packages.

Packages
sudo apt update
sudo apt install -y git build-essential libprotobuf-dev libprotoc-dev protobuf-compiler
From source
sudo apt update
sudo apt install -y git build-essential autoconf automake libtool curl unzip
git clone --recursive https://github.com/protocolbuffers/protobuf.git
cd protobuf/cmake
cmake . -Dprotobuf_BUILD_SHARED_LIBS=ON
make -j8
sudo make install

Build library

mkdir blickfeld-scanner-lib/build && cd blickfeld-scanner-lib/build
cmake ..
make -j8
sudo make install

Follow the Getting started guide to write your first application.

Windows

Dependencies

Building on Windows has been tested with MSVC++ and Microsoft nmake. The minimum requirement is a Microsoft Visual Studio 10 compiler. The VC++ build tool can be found here: https://visualstudio.microsoft.com/de/downloads/. Install an up-to-date CMake from: https://cmake.org/download/.

To activate full support, Protocol Buffers are required. It is recommended to use CMake External Projects. An example will be available soon.

Build library

git clone --recursive https://github.com/Blickfeld/blickfeld-scanner-lib.git
mkdir blickfeld-scanner-lib/build && cd blickfeld-scanner-lib/build
cmake .. -DBF_USE_SYSTEM_PROTOBUF=OFF
cmake --build . --target ALL_BUILD --config Release

Note

The BF_USE_SYSTEM_PROTOBUF=OFF flag builds the BSL with reduced functionality. Read Dependencies for more information.

Compile options

Note

Detailed information about the CMake compile options will be available soon.
