Ah, seems compilation of the ittapi crate on windows is broken. Any ideas @abrown @jlb6740?
Wasmtime GitHub notifications bot (Apr 07 2022 at 17:58):abrown commented on issue #4003:
I looked into this but don't know yet how to resolve it: the compilation failure is due to
strnlen_snot being available in MinGW by default (it is, after all, a non-standard function). There are some thoughts out there that adding--enable-secure-apiwill include the headers with this function, but before I add that toittapi-sys'sbuild.rs, I wanted to be able to reproduce the issue.Locally I was unable to reproduce: after installing MSYS2 and compiling the
ittapicrates withcargo build --target x86_64-pc-windows-gnu, everything seemed to build as normal. When I runcargo test --target x86_64-pc-windows-gnu, I get a different error:linker x86)64-w64-mingw32-gcc not found.I then attempted to reproduce on ittapi's CI: using a similar setup to the Wasmtime workflow, I added
x86_64-pc-windows-gnuas a target in the matrix. With thewindows-latestOS, however, the crates built and tests ran. With thewindows-2019OS, then I observe a completely different failure related tolibclang.dllbeing inaccessible.Any suggestions?

@bnjbvr: since we can't really replicate this, we could just disable the ittapi dependency for MinGW builds?
Wasmtime GitHub notifications bot (Apr 13 2022 at 17:09):bnjbvr commented on issue #4003:
@abrown Need to check but I think that we do use this target to cross-compile internally. If so at least I might find people who could poke at this, maybe...

Seems we don't use it, so yeah we could disable ittapi on mingw then, and if someone wants to support that, they would need to contribute a patch. Does it sound acceptable?

It sounds acceptable to me, though others feel free to comment. I'm not sure how much energy to put into MinGW since I don't use it much (ever!) and I wonder sometimes if it has been obsoleted by WSL.

Personally I find managing platform-specific exceptions and such to APIs not easy to maintain over time. To that end I would prefer to see this solved. It looks to me like MinGW doesn't provide the
strnlen_sfunction which is the source of this error. The only reason we're seeing this now is probably because something in theittapicrate is calling a function we didn't call before in the C library and the C function requiresstrnlen_sor something like that.Locally I was unable to reproduce: after installing MSYS2 and compiling the ittapi crates with cargo build --target x86_64-pc-windows-gnu, everything seemed to build as normal
That's because when you build an rlib it doesn't actually link anything, so this doesn't verify that symbols are actually present on the system.
When I run cargo test --target x86_64-pc-windows-gnu, I get a different error: linker x86)64-w64-mingw32-gcc not found.
If the
)there isn't a typo then that's a misconfigured compiler somewhere. Otherwise this may mean you're not running the command in an MSYS2 shell or something like that. Basically if the linker isn't being invoked you won't be able to reproduce this issue.With the windows-latest OS, however, the crates built and tests ran
I don't think that the CI is configured correctly which is why this seems to work. In the logs I see:
Running tests\bindgen-up-to-date.rs (target\debug\deps\bindgen_up_to_date-ae57c289f5ef2e2d.exe)but if you're cross compiling the path to the binary should be
target\x86_64-pc-windows-gnu\debug\deps\.... You added this to the CI configuration:- run: echo CARGO_BUILD_TARGET=${{ matrix.target }} >> $GITHUB_ENV if: matrix.target != ''but I don't think that works because the shell you're using is windows cmd or powershell (I dunno which) and probably doesn't use
$foofor environment variables. This I believe means you're not actually configuring Cargo for cross-compilation.

Very good call, @alexcrichton! Managed to reproduce the compilation error on
ittapinow: https://github.com/intel/ittapi/pull/61

This should be merge-able once GitHub's virtual environment for Windows is updated with the latest version of MinGW: https://github.com/actions/virtual-environments/pull/5729.
Wasmtime GitHub notifications bot (Jun 23 2022 at 23:03):abrown commented on issue #4003:
I believe that the updated version of MinGW (which includes the missing
strnlen_sdefinition) has been rolled out to the machines that run thewindows-latestCI jobs. Over in https://github.com/intel/ittapi/pull/63 I was able to buildittapiwithout issues onwindows-latest. I'm re-running CI here to check if we can actually merge this now.

I believe the issue here is that we're pinned to windows-2019 (see https://github.com/bytecodealliance/wasmtime/pull/3864 for info on that) so we're not getting updates. I'd reiterate though that there's no requirement to get this working on all platforms. Disabling this on mingw is fine.
Wasmtime GitHub notifications bot (Jul 18 2022 at 14:32):bnjbvr commented on issue #4003:
Just added a commit that disables this on windows + mingw, and it seems to compile fine. Unfortunately there's an unrelated MacOS build error (Github says the CI run has been cancelled), and I can't request a retry, so could anyone with the right authorization bits please do that?
