libsigmf is a header-only C++ library for working with SigMF metadata. It is provided under the Apache License 2.0 and the copyright notice can be found in NOTICE.

To use libsigmf, your application needs to #include <sigmf.h> and link to libflatbuffers.so.

One option is to include libsigmf (this git repo) as a submodule inside your project sources. A typical cmake usage would look like the following (see the CMakeLists.txt in this examples directory for what this looks like in real usage).

add_executable(example_record_with_multiple_namespaces example_record_with_multiple_namespaces.cpp)
target_link_libraries(example_record_with_multiple_namespaces libsigmf::libsigmf)
target_include_directories(example_record_with_multiple_namespaces PRIVATE ${CMAKE_BINARY_DIR}/include)

Ideally you install libsigmf either system-wide or in a prefix. Provided CMake configuration then enables you to include libsigmf in your project by including this

find_package(libsigmf REQUIRED)
add_executable(my_awesome_record my_awesome_record.cpp)
target_link_libraries(my_awesome_record libsigmf::libsigmf)

libsigmf internally has a class sigmf::VariadicDataClass that does the heavy lifting of keeping objects of collected metadata using different SigMF namespaces. As a convenience, there are 4 classes that directly deal with SigMF objects that are all you need to use:

1. sigmf::SigMF
2. sigmf::Global
3. sigmf::Capture
4. sigmf::Annotation
