ERROR: Package LIBSVM errored during testing (exit code: 3221226356)

It reports an error when I test LIBSVM.

@WuSiren Thanks for reporting, but could you please provide more context as below.

I am not able to reproduce the fail in this context:

The version of LIBSVM is [b1bec4e5] LIBSVM v0.8.0, and Julia is

And I fail to run even the simplest example:

# Training data
X = [-2 -1 -1 1 1 2;
     -1 -1 -2 1 2 1]
y = [1, 1, 1, 2, 2, 2]

# Testing data
T = [-1 2 3;
     -1 2 2]

# Precomputed matrix for training (corresponds to linear kernel)
K = X' * X

model = svmtrain(K, y, kernel=Kernel.Precomputed)

The editor (VS Code) reports:

And nothing changes after I remove and reinstall this package.

It works well under Julia v1.10.3.

[ablaom]

This looks like a known Julia 1.9 issue, fixed in 1.10. See https://github.com/JuliaML/LIBSVM.jl/issues/95.

@barucden Do you think we should bump julia [compat] to 1.9? I don't know if there a plan for a backwards fix for julia 1.9.

[WuSiren]

OK, thank you very much! @ablaom 🤝

Anyway, I've upgraded to Julia1.10.

[barucden]

The fix (https://github.com/JuliaLang/julia/pull/50135) was backported and released with julia 1.9.2.

I am not against bumping the compatible julia version. An alternative might be to raise a warning for the affected users:

if Sys.iswindows() and (v"1.8.3" < VERSION < v"1.9.2")
    @warn "LIBSVM is known to error under the current Julia version. Consider upgrading to Julia 1.9.2 (see https://github.com/JuliaML/LIBSVM.jl/issues/95)."
end

(Speaking of bumping versions -- we haven't made a release (8.0.1) with the LIBLINEAR version bumped to 0.7. Should we release that?)

That would be nice.

Ah, thanks for that. I see @WuSiren was indeed using 1.9.0. In that case I don't think we need to take any further action and can close this. I think it's fair to assume users are using the latest patch of any package.

[barucden]

Alright. Closing as duplicate of #95.
