Minuit2

This is a Julia package to use C++ Minuit2 package for function minimization. The binaries for Minuit2 are built here: https://github.com/JuliaPackaging/Yggdrasil/tree/master/M/Minuit2

The interface code between C++ and Julia can be found here https://github.com/jstrube/Minuit2_Julia_Wrapper and needs to be installed locally for the time being. If you cannot build the wrapper binaries using BinaryBuilder, you can download the artifacts from here: https://github.com/jstrube/Minuit2_Julia_Wrapper_jll.jl

The Pkg documentation may have some helpful tips to achieve this: https://julialang.github.io/Pkg.jl/v1/artifacts/#Overriding-artifact-locations

minuit2.jl's Issues

Segfault on PkgEval / Julia 1.10

Testing of Minuit2.jl fails on PkgEval (which tests julia#master) presumably because the CxxWrap-based glue layer hasn't been rebuilt recently, see JuliaInterop/CxxWrap.jl#326. Would it be possible to do so? Until then, I'll disable testing of this package on PkgEval.jl (as the package otherwise just segfaults, see e.g. https://s3.amazonaws.com/julialang-reports/nanosoldier/pkgeval/by_date/2022-11/24/Minuit2.primary.log)

hm, `InitError: could not load library `

installation works fine

] add Minuit2_Julia_Wrapper_jll
] add https://github.com/jstrube/Minuit2.jl

breaks at using

julia> using Minuit2

any ideas?

unsatisfied requirements for Minuit2_Julia_Wrapper_jll

just wanted to play around but got some problems on the installation step

perhaps, the answer is in here (?)
