Dear all,  
This is probably a trivial error, but I cannot see it myself. Here is my build.jl:

```julia
dependencies = [
    "https://github.com/JuliaPackaging/JuliaBuilder/releases/download/v1.0.0-2/build_Julia.v1.0.0.jl",
    "https://github.com/JuliaInterop/libcxxwrap-julia/releases/download/v0.5.1/build_libcxxwrap-julia-1.0.v0.5.1.jl",
    "https://github.com/TeroFrondelius/tfelBuilder/releases/download/v0.1.0/build_tfel_binaries.v3.2.1-master.jl",
    "https://github.com/TeroFrondelius/mgisBuilder/releases/download/v0.2.0/build_mgis_binaries.v1.0.0-master.jl"
]

for build_script in dependencies
    include(download(build_script))
end

```

Here it is in the form of pull request: [build.jl to add binary dependencies by TeroFrondelius · Pull Request #1 · JuliaFEM/MFrontInterface.jl · GitHub](https://github.com/JuliaFEM/MFront.jl/pull/1)

So what error are you getting? Because I suspect my error is different from your error? Unless your error is:

```julia
Your platform ("x86_64-pc-linux-gnu", parsed as "x86_64-linux-gnu-gcc8-cxx11") is not supported by this package!

```

Which I suspect is because my system has gcc9 installed…

Here is the fix:

```julia
dependencies = [
    "https://github.com/JuliaPackaging/JuliaBuilder/releases/download/v1.0.0-2/build_Julia.v1.0.0.jl",
    "https://github.com/JuliaInterop/libcxxwrap-julia/releases/download/v0.5.1/build_libcxxwrap-julia-1.0.v0.5.1.jl",
    "https://github.com/TeroFrondelius/tfelBuilder/releases/download/v0.1.0/build_tfel_binaries.v3.2.1-master.jl",
    "https://github.com/TeroFrondelius/mgisBuilder/releases/download/v0.2.0/build_mgis_binaries.v1.0.0-master.jl"
]

for build_script in dependencies
    include(download(build_script,"build_script.jl"))
end

```

I have to say it was really difficult to catch. For an examplanation the original version downloads the binaries to `/tmp/usr` folder instead of `<MFront.jl>/deps/usr`.
