The problem is caused by missing visibility attributes for symbols used outside of the library (as such part of the public interface even though some of these symbols are declared in the internal namespace).

This PR adds proper annotations to public symbols using the new export.h header. This fixes #1070 and enables fixing #1022.

Selective symbol export has the benefit of reducing the size of the generated libbenchmark.so.*. For instance, on Ubuntu 20.04 I observe a size reduction from 436K to 420K.

Open questions:

• How should export.h be defined for Bazel builds?
• Should CI build shared library variant by default? Ideally, with CMAKE_CXX_VISIBILITY_PRESET=hidden and possibly CMAKE_VISIBILITY_INLINES_HIDDEN=ON, and -flto enabled to avoid regressions

[LebedevRI]

Sanity check: this should not force anything to be exported UNLESS we are actually building shared libbenchmark/libbenchmark_main.

[sergiud]

I'm not sure what you mean. BENCHMARK_EXPORT is defined to be non-empty iff the benchmark target is built as a shared library.

[LebedevRI]

Are these changes required here?

[sergiud]

Not quite sure. I stumbled upon this while fixing the DLL export under MSVC.

[LebedevRI]

I would still like to hear an explanation as to why this is okay and not does result in ABI mismatch.

[sergiud]

That's a good question. I've reverted the changes in a separate commit here so you can investigate the issue yourself. The MSVC 2022 runner fails now at linking.

[sergiud]

Looks like MSVC does not allow to set the language standard prior to C++11. Therefore, an ABI mismatch cannot generally occur.

[LebedevRI]

I'm not sure what you mean. BENCHMARK_EXPORT is defined to be non-empty iff the benchmark target is built as a shared library.

That's what i wanted to hear, yes.

[dmah42]

Open questions:

• How should export.h be defined for Bazel builds?

it depends what the cmake version is doing. do the same thing. :)

maybe something like https://github.com/RobotLocomotion/drake/blob/master/tools/workspace/lcm/package.BUILD.bazel#L5 ?

• Should CI build shared library variant by default? Ideally, with CMAKE_CXX_VISIBILITY_PRESET=hidden and possibly CMAKE_VISIBILITY_INLINES_HIDDEN=ON, and -flto enabled to avoid regressions

that would be a good idea i think.

[sergiud]

The following parts need to be clarified as well:

benchmark/src/CMakeLists.txt

Line 25 in 6d51a11

SOVERSION ${GENERIC_LIB_SOVERSION}

benchmark/src/CMakeLists.txt

Line 62 in 6d51a11

SOVERSION ${GENERIC_LIB_SOVERSION}

Currently, the .so version is bound to the major version of the library. However, this is not quite correct. The .so version should be incremented every time the ABI changes. Given that only public symbols are now exported instead of all the symbols, SOVERSION should reflect the change .

[sergiud]

If there are no opinions, I guess it is fine to increment SOVERISON which is the most reasonable course of action anyway.

[dmah42]

i think i'm ok with this. but i'm also aware there are potential ramifications of the change that i'm not aware of. thank you so much for your patience, @sergiud.

@LebedevRI can you take a look at some point and see if you have any remaining concerns?

[sergiud]

Looks like @LebedevRI does not want to review.

[dmah42]

ok, i'll take that as an implicit upvote then :)

[sergiud]

Thanks!
