PMT Objects represent a serializable container of data that can be passed across various interfaced. In GNU Radio, these are used to carry data on stream tags or through message passing, and could be used to pass data to external consumers of GNU Radio. This PMT library restructures the API beyond what has previously been included in the GNU Radio codebase to more closely align with the functionality and usability in the C++ Standard Template Library, and uses std::variant for the underlying data storage and serialization
PMTlib uses meson and ninja to manage the build process, which can be installed via pip and your package manager
pip install meson
cd pmt
meson setup build --buildtype=debugoptimized --prefix=[PREFIX] --libdir=lib
cd build
ninja
ninja install
The path to emsdk
must be provided. It can be done in 2 different ways.
Create file emscripten-toolchain.ini
in the project root directory with the following content:
[constants]
toolchain = '/path/to/emsdk/upstream/emscripten/'
And then execute the following command:
meson setup build_wasm --cross-file emscripten-toolchain.ini --cross-file emscripten-build.ini -Denable_python=false -Denable_testing=true
Set toolchain
constant directly in emscripten-build.ini
file in [constants]
section:
[constants]
...
toolchain = '/path/to/emsdk/upstream/emscripten/'
And then execute the following command:
meson setup build_wasm --cross-file emscripten-build.ini -Denable_python=false -Denable_testing=true
The next steps are:
cd build_wasm
ninja
ninja test
If error Dependency gtest found: NO
occurred, do the following commands:
cd [pmt_project_root_dir]
meson wrap install gtest
It creates subprojects/gtest.wrap
wrap file for gtest
.
