The Module test fails on windows CI, but the error is ignored?

@ClausKlein unfortunately MSVC was not able to actually build modules the last time I checked. If there's a workaround I'd appreciate a PR.

That's something new. Could you please provide more logs and the configure+build commands

[ClausKlein]

It is from your CI: https://github.com/boostorg/any/actions/runs/20689068722/job/59394456776#logs

see too https://discourse.cmake.org/t/linker-error-with-cxx-modules/15449

[apolukhin]

@ClausKlein can you please double check the status of this issue? It should have been fixed by now

[ClausKlein]

with Boost v1.91.0 it still fails on my CI: https://github.com/ClausKlein/boost-cmake/actions/runs/27907269195/job/82578050400#step:7:284

@ClausKlein and with Boost 1.92 ?

[ClausKlein]

@ClausKlein and with Boost 1.92 ?

ON CI same result with Windows build!

clang++ fails now with BUILD_TESTING=1; see https://github.com/ClausKlein/any/actions/runs/31955614430/job/95185693257

On OSX, g++-16 still fails totally.

[ClausKlein]

Sorry to bother you: but you add more and more modules to boost, each with the same problems.

see my patches at ClausKlein/boost-cmake#12

and https://github.com/ClausKlein/boost-cmake/tree/feature/bump-to-boost-v1.92.0

i.e.:

gmake all
