Build Executable Julia Module including Plots.jl on Windows 10 via PackageCompiler

gen_exec.ps1

$dllpath=(julia -e 'using GR; s=joinpath(dirname(dirname(pathof(GR))),\"deps\",\"gr\",\"bin\"); s = s* \";\"; print(s)')
$Env:Path+=$dllpath
julia -e 'using PackageCompiler; build_executable(\"hello.jl\",\"hello\")'

hello.jl

module Hello

using Plots

function main()
    xs = -π:0.01:π
    p=plot(xs, sin.(xs));
    savefig(p, "sin_curve.png")
end

Base.@ccallable function julia_main(ARGS::Vector{String})::Cint
    main()
    return 0
end

end

Usage

To resolve an error that tells libgr.dll does not found, we need add path of which libgr.dll lives.
I found it lives in C:\Users\USER1st\.julia\packages\GR\IVBgs\deps\gr\bin on my Windows 10 PC.

• Open PowerShell and execute our PowerShell script.

PS > .\gen_exec.ps1
PS > .\builddir\hello.exe

you will find builddir/sin_curve.png as output result.

References (about PowerShell)

• Powershell add to path, temporarily [duplicate]
• How do I capture the output into a variable from an external process in PowerShell?

Another Solution

I found we do not need prepare PowerShell script ...

# gen_executable.jl
using PackageCompiler
using GR

s=joinpath(dirname(dirname(pathof(GR))),"deps","gr","bin")
s*=';'

ENV["PATH"] *= s

build_executable("hello.jl","hello")

$ julia gen_executable.jl

Appendix

• multi platform support

# gen_executable.jl
using PackageCompiler
using Pkg

if in("GR",keys(Pkg.installed()))
    @eval import GR
else
    Pkg.add("GR")
    @eval import GR
end

if Sys.iswindows()
    s=joinpath(dirname(dirname(pathof(GR))),"deps","gr","bin")
    s*=';'
    if !endswith(ENV["PATH"],';')
        ENV["PATH"] *= ';'
    end
    ENV["PATH"] *= s
else
    s=joinpath(dirname(dirname(pathof(GR))),"deps","gr","lib")
    s*=':'
    if haskey(ENV, "LD_LIBRARY_PATH")
        ENV["LD_LIBRARY_PATH"] *= s
        if !endswith(ENV["LD_LIBRARY_PATH"],':')
            ENV["LD_LIBRARY_PATH"] *= ':'
        end
    else
        ENV["LD_LIBRARY_PATH"] = s
    end
end

build_executable("hello.jl","hello")

For those who came from terasakisatoshi/myjulia, all you have to do is copy hello.jl and gen_executable.jl to your work space and execute command below:

$ docker run --rm -it -v $PWD:/work -w /work terasakisatoshi/myjulia:<tag> julia gen_executable.jl
$ docker run --rm -it -v $PWD:/work -w /work terasakisatoshi/myjulia:<tag> ./builddir/hello

where <tag> depends on your OS, for example if you're using MacOSX(e.g. Mojave), for example, replace <tag> with mac.
