@miklhh one likely reason for the failure is that we use dynamic linking flags somewhere. As you know these things much better than me, can you please have a look and suggest what to change?

[oscargus]

I got this error when compiling on my Windows laptop (which I usually do not compile against, but trying to get to work):

  lld-link: error: /failifmismatch: mismatch detected for 'RuntimeLibrary':
  >>> _apytypes.cp312-win_amd64.pyd.p/subprojects_nanobind-2.8.0_src_nb_combined.cpp.obj has value MT_StaticRelease
  >>> subprojects/highway\libhwy.a.p/hwy_targets.cc.obj has value MD_DynamicRelease

so I think we can say that Highway is the issue here. However, google/highway#2641 (comment) claims that CMake should use a static target by default. So why do we get a dynamic one here? (Or am I missing what this means?)

[miklhh]

I open a upstream fix for the WASM shared-library problem here

• fmt: properly provide header-only dependency mesonbuild/wrapdb#2379

[miklhh]

I'll rebase this on top of main

[miklhh]

I'll also bump the cibuildwheel version to 3.1.4 and pin the Pyodide wheel version to 0.28.2. That way, the uploaded wheel artifact from this job can be directly tested in the interactive console on Pyodides website:

https://pyodide.org/en/stable/console.html

By the way, looking at the job logs, it seems that the APyTypes test suite is not running.
