Are there any plans for implementing an ahead-of-time-compiler in Julia that can generate standalone executables?

I believe such a feature would attract a very large set of new (system) programmers typically programming in system languages such as C, C++, D, Zig, Rust and Go.

See the `build_executable` function in PackageCompiler: [GitHub - JuliaLang/PackageCompiler.jl: Compile your Julia Package](https://github.com/JuliaLang/PackageCompiler.jl/)

Is this really stable!!!?

People are asking for an AOT-compiler for version 1.x of Julia.

Should

```julia
Pkg.add("PackageCompiler")

```

work? It fails for me as

I wouldn’t necessarily call it stable (it does have a major version number of “0”), but it’s worked for me on a wide variety of use-cases for 0.6. My guess for why it’s failing to build is that it isn’t yet compatible with 1.0. If you’d like to try to help with fixing that, I’d recommend downloading 0.7 and fixing any warnings generated by PackageCompiler.

This has seen massive improvements in the last two years. PackageCompiler was rewritten from the ground up. See Kristoffer Carlsson’s talk at this year’s juliacon for an overview of the current state of PackageCompiler:
