@aduh95, I'll look into Windows failures.

[StefanStojanovic]

This is what got it to compile for me locally. In short, it was a configuration problem(s), so gyp changes resolved it all.

@nodejs/platform-aix Build failure: ../deps/perfetto/sdk/perfetto.h:1035:5: error: function-like macro 'PERFETTO_BUILDFLAG_DEFINE_PERFETTO_OS_APPLE' is not defined

I think the actual error is this:
e.g. https://ci.nodejs.org/job/node-test-commit-aix/65261/nodes=aix72-power9/console

01:02:46 In file included from ../deps/perfetto/sdk/perfetto.cc:21:
01:02:46 ../deps/perfetto/sdk/perfetto.h:295:2: error: OS not supported (see build_config.h)
01:02:46   295 | #error OS not supported (see build_config.h)
01:02:46       |  ^

Same failure is seen on SmartOS.

[jasnell]

doh!

[aduh95]

How should we proceed? Force --without-perfetto for those platforms or wait until support is added upstream? @nodejs/platform-aix @nodejs/platform-smartos

[jasnell]

good question. I think as long as the observable behavior with trace events is still the same either way, forcing --without-perfetto on those platforms is likely ok. We'd need to avoid a case where tracing output is broken on just those. If we still consider this experimental, then it should be fine omitting the unsupported platforms, however.
