Multiple libraries failing with unknownsymbol 'expm1' on mingw32

[Anviking]

Describe the bug

After bumping dependencies in cardano-wallet we have some haskell libraries failing with unknownsymbol 'expm1' on mingw32.

• Build system: mingw32 x86_64-linux to windows cross compilation
• GHC version: 9.6.6
• Haskell.nix version: 42f73d0

Steps To Reproduce

git clone https://github.com/cardano-foundation/cardano-wallet.git
cd cardano-wallet
git checkout paolino/4993/bump-node-to-10.2.1 
# PR https://github.com/cardano-foundation/cardano-wallet/pull/5031
# current commit: 3060adbe1ee818300b7d1fd0990e39967c1ad9b2
nix build -L -o result/windows .#ci.artifacts.win64.release

Expected behavior

Haskell libraries succeed to build or at least don't fail with error below.

Actual behaviour

error: builder for '/nix/store/i1j4q4dw6vfr1mm5khiyd5fwygy2in0f-parsers-lib-parsers-x86_64-w64-mingw32-0.12.12.drv' failed with exit code 1;

Additional context

Bumping selective-0.5 to 0.7.0.1 appears to make it compile, and fail on parsers-0.12.12 instead.

parsers-0.12.12 is the latest one though so can't bump any further.

@hamishmack @angerman any ideas here? 🙏 I think it looks different from #2314

[angerman]

Yes, this should be easier than the dreaded #2314. This is basically just iserv missing some symbol.

[hamishmack]

Please try using ucrt64 instead of mingwW64:

Thanks, it fixed the windows build but somehow the linux build broke in a weird way https://buildkite.com/cardano-foundation/cardano-wallet/builds/9823#0195b949-695d-4e3f-a9ec-756b9e8f49b5

cardano-wallet.exe-v2025> cp: missing destination file operand after 'cardano-wallet.exe-v2025-03-04-linux64/auto-completion/bash/cardano-wallet.exe.sh'

It seems suspecicious that the linux build mentions .exe and that the linux build even got affected given the patch looked like it only affected windows.

Does this ring any bells for you?

Edit: wait nvm hold up a minute, I was pretty sure I changed only the windows build but looks I didn't 🧐 🧐

[Anviking]

Yes works perfectly. Thanks a lot, @hamishmack !
