The v5 bazel toolchains don't currently provide a gdb binary, so the pretty printer tests can't run using the v5 bazel toolchain as-is. I've also been unable to get them to run directly from scons with a v5 toolchain installed under /opt.

Until they get ported to bazel, it's going to be a bit of a pain to run the pretty printer tests. A command like this will build and run them: ./buildscripts/scons.py --opt=off --dbg=on --variables-files=etc/scons/mongodbtoolchain_v5_clang.vars --link-model=dynamic +pretty-printer-tests. Be warned that it seems to build nearly everything (and these tests won't run through ninja either), so it takes a long time.

To bypass the issue with running directly from scons and actually test the pretty printers against a v5 toolchain, you can do the following: ./buildscripts/scons.py --opt=off --dbg=on --variables-files=etc/scons/mongodbtoolchain_v5_clang.vars --link-model=dynamic build/install/bin/pretty_printer_test_launcher_optimizer_gdb_test.py build/install/bin/pretty_printer_test_launcher_pretty_printer_test.py build/install/bin/pretty_printer_test_launcher_lock_gdb_test.py build/install/bin/pretty_printer_test_program and then run each of those three python scripts.

There's a better alternative in SERVER-79122: python buildscripts/scons.py --dbg=off --opt=on --link-model=dynamic --variables-files=./etc/scons/mongodbtoolchain_stable_gcc.vars GDB_PPTEST_PYONLY=1 install-pretty-printer-tests-pyonly
python buildscripts/resmoke.py run --suite=pretty-printer-tests
