Build and Test on Linux

Meson is use to manage build and test functions. The main steps are

meson setup build
cd build
ninja
meson test

All tests should pass, but the cc_hd_FEC may fail from time to time because of the bit error rate (BER) tests, which push the boundary for SNR as part of the test suite. That means that for a given test run, the noise statistics may cause the SNR to be lower than the assumed mean SNR by enough to cause a few extra bit errors that just push the results into a fail. Re-running that test a a few times should be more successful, showing the FEC method works.

A useful option is to use valgrind to look for memory leaks. For example, the cc_hd_FEC test can be checked using

meson test --wrap='valgrind -s --leak-check=full --show-leak-kinds=all  --undef-value-errors=no --error-exitcode=1' cc_hd_FEC

Likewise, total memory usage can be investigated using

meson test --wrap='valgrind --tool=massif' cc_hd_FEC

see valgrind man pages for more information on using massif.

GNURadio

/gnuradio contains both flow graphs for deployment and test, along with various test scripts and binary data files for development work. Everything is designed for GNURadio 3.9.4 and the Out of Tree module gr-satellites from Daniel Estevez.
