build: Add -fvisibility=hidden flag for macOS host

hebasto commented at 5:56 pm on November 26, 2021: member

On master (a213bd63ca0c96e8c98e84ec916f83c4ba28d486) when building bitcoin-qt with depends for macOS, clang spams with a load of warnings like this one:

0ld: warning: direct access in function 'QMetaTypeIdQObject<QWindow*, 8>::qt_metatype_id()' from file '/Users/hebasto/bitcoin/depends/aarch64-apple-darwin21.1.0/plugins/platforms/libqcocoa.a(qcocoaintegration.o)' to global weak symbol 'QtMetaTypePrivate::QMetaTypeFunctionHelper<QWindow*, true>::Construct(void*, void const*)' from file 'qt/libbitcoinqt.a(libbitcoinqt_a-walletcontroller.o)' means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings.

The cause of such warnings is the fact that -fvisibility=hidden is used during building of the qt package by default, but not for all of other building stages. That is fixed in this PR.

Fixing these warnings is fine, they’ve been around forever. However concept NACK on the approach. Similar to #23612, creating (undocumented) special-cases in depends, should be a last resort, especially if it’s just to suppress some warnings. It would probably be unexpected to someone using depends, that when they happen to build a certain dependency, on a particular OS, they get additional (unrelated) configure options turned on, with no explanation.

The cause of such warnings is the fact that -fvisibility=hidden is used during building of the qt package by default.

-fvisibility=hidden is used by default by other packages as well. i.e Boost.

Would there be any downside to just building everything in depends, for darwin, with -fvisibility=hidden?

Got it. Just a note that a similar approach is already used: https://github.com/bitcoin/bitcoin/blob/e7507f333bc93047d0baadea4fde19f770dacb56/depends/config.site.in#L114-L116

… creating (undocumented) special-cases in depends…

Is printing reduce_exports value in the ./configure summary a proper way to document the actual behavior?

Would there be any downside to just building everything in depends, for darwin, with -fvisibility=hidden?

Building everything in depends with -fvisibility=hidden won’t help. It requires to build with depends with -fvisibility=hidden. And that, btw, was my initial approach to handle those warnings.

Got it. Just a note that a similar approach is already used:

Yes, however always turning off reduced exports when debugging, isn’t really the same as turning it on when building a certain dependency, on a single OS. One is a generic, likely expected behavior, the other is a special case that’s (undocumented) existence wouldn’t be clear to anyone looking at the code.

Building everything in depends with -fvisibility=hidden won’t help. It requires to build with depends with -fvisibility=hidden.

I think you’ve misunderstood my suggestion. I meant add -fvisibility=hidden to the darwin CC & CXX, which “builds everything” in depends with the flag, and then passes it though to configure. i.e https://github.com/fanquake/bitcoin/commit/fe7807d43463e9deeb2fd2a1cd36e6d80d3aa1b8. That would seem to achieve the same outcome as what’s being proposed in this PR.

build: Add -fvisibility=hidden flag for macOS host

With all benefits of reducing exports, there are no evidences of any
drawback while compiling with clang for macOS. Also, when building with
depends, it is expected that different translation units are being
compiled with the same visibility settings.

this does fix some of the spamming:

master:

0make -j8 2>&1 > /dev/null | grep -o “warning” | wc -l
1   12100

pr:

0make -j8 2>&1 > /dev/null | grep -o "warning" | wc -l
1   12066

but i wonder if this is worth it considering the drop, perhaps attack the spamming from a different angle? Most of the warnings are coming out of boost. Put the 12100 warning in contrast with the amount of warnings i get building on linux

linux:

0 make -j8 2>&1 > /dev/null | grep -o "warning" | wc -l
1  0

I’d say most of the warnings are emitted by a compiler, and most of them can be silenced with --enable-suppress-external-warnings configure option.

But this PR deals with linker warnings.

Personally I don’t think the warnings matter. I think if you want to avoid them, use --enable-reduce-exports, which already exists, and has the same effect. I know this PR was changed to append to cflags based on what I said above, but thinking about this more, it’s weird to do this and make it such that macOS depends builds are basically always using --enable-reduce-exports by default.
