Handling large volume of boost unit test related warnings with clang-tidy

Question

I'm in the process of setting up a project. I have skeleton tests in place using boost unit-test. Unfortunately a large number of warnings are spawned from the macro expansions. Is there a way to disable these, without have to specify individual line numbers?.

This occurs even when I have a // NOLINT.

An example:

/home/peter/checkouts/canopen-gateway/./unittests/projs/server/exe/testunit-tcp-socket.cpp:12:1: warning: construction of 'end_suite12_registrar12' with static storage duration may throw an exception that cannot be caught [cert-err58-cpp]
BOOST_AUTO_TEST_SUITE_END()  // NOLINT
^

#define BOOST_AUTO_TEST_SUITE_END()                                     \
                                                                        ^

Answer 1

Try wrapping the offending code thus:

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdisabled-macro-expansion"

// your code here

#pragma clang diagnostic pop

Answer 2

You probably didn't paste the entire error message, but somewhere in there should be a line that says

warning: disabled expansion of recursive macro [-Wdisabled-macro-expansion]

You can disable this by passing -Wno-disabled-macro-expansion to the clang command line.
