Installing open62541

Manual installation

You can install open62541 using the well known make install command. This allows you to use pre-built libraries and headers for your own project.

To override the default installation directory use cmake -DCMAKE_INSTALL_PREFIX=/some/path. Based on the SDK Features you selected, as described in Build Options, these features will also be included in the installation. Thus we recommend to enable as many non-experimental features as possible for the installed binary.

The recommended cmake options for a default installation are:

git submodule update --init --recursive
mkdir build && cd build
cmake -DBUILD_SHARED_LIBS=ON -DCMAKE_BUILD_TYPE=RelWithDebInfo -DUA_NAMESPACE_ZERO=FULL ..
make
sudo make install

This will enable the following features in 0.4:

  • Discovery
  • FullNamespace
  • Methods
  • Subscriptions

The following features are not enabled and can be optionally enabled using the build options as described in Build Options:

  • Amalgamation
  • DiscoveryMulticast
  • Encryption
  • Multithreading
  • Subscriptions

Important

We strongly recommend to not use UA_ENABLE_AMALGAMATION=ON for your installation. This will only generate a single open62541.h header file instead of the single header files. We encourage our users to use the non-amalgamated version to reduce the header size and simplify dependency management.

In your own CMake project you can then include the open62541 library using:

# optionally you can also specify a specific version
# e.g. find_package(open62541 0.4.0)
find_package(open62541 REQUIRED COMPONENTS Events FullNamespace)
add_executable(main main.cpp)
target_link_libraries(main open62541::open62541)

A full list of enabled features during build time is stored in the CMake Variable open62541_COMPONENTS_ALL
