Any examples out there making use of 3rd party packages? Makie, DataFrames, etc. Even using something like DelimitedFiles I’m struggling to get it to compile.
I played around with it and specifically found issues with ssl if you try to use HTTP.jl (ill make an issue later). IIRC the certificate store was being looked for in the wrong place.
Forgive me for asking but what is the main usecase of juliac, given that the binaries produced are not portable to other machines? is it meant just for simplifying system images (which is very useful on its own)?
also, out of curiosity - why are the binaries so huge if julia isn’t bundled?
How do you come to the conclusion that the binaries are not portable? I mean, you have to make sure to compile using an instruction set that the target machine supports. I think this is possible using the correct command line parameters. And you need to make sure that paths to shared libraries or other resources are correct. This might have to be fixed in the packages if it does not work yet.
Well, there’s quite a lot you have to do at the moment to make the binary run on another machine, unless it happens to have a very similar environment. Specifically on Linux,
This won’t run on another machine unless there is a user account of the same name with a matching Julia installation.
It is possible to make simple programs portable, I have at least managed that on Linux, but the tooling simply isn’t there yet to make it convenient and not require a certain amount of technical knowledge.
Well, even in Julia 1.12 (which is not yet released) juliac.jl is marked as experimental. I think the goal is to create portable binaries, but nobody should expect that this will be convenient before next year.
when I think “portable”, it means something that can be run on a different machine that has the same system libraries but not julia+packages installed.
Obviously if i clone an exact copy of my entire filesystem/docker image everything should work but that’s a very narrow interpretation of portability. eg if you compile an sbcl image you get a self contained binary that would work on similar architectures regardless of preinstalled sbcl+packages - only ffi based libs are needed.
Since the compiled artifacts for rather trivial examples take hundreds of mb, i was surprised that they still require the entire toolchain and libraries separately. Hence the question.
I understand this is work in progress but was curious regarding intended scope/usecases for this project as envisioned for stable release. Is it mainly to improve TTFP on the same machine? Distributing closed source “apps” to “labs”? Dropping off my compiled artifacts on a server? Some other scenarios?
Being able to create and distribute FMU components (see: https://fmi-standard.org/) would be great. And if the size goes down from 1GB to 100MB many users would already be happy. These components are often simulation models of components of cars or airplanes, a zip file containing one or more dll/so files and an xml file with the interface description. A company that supplies the component gives it to the company that uses it.
And you can easily use the components in Modelica, Simulink, Python or whatever your prefered simulation environment is. If you could easily write these components in Julia this would open up a huge market.
I’m very interested in applying a julia.c for Windows.
I face two problems when using juliac:
Using julia 1.12-beta, and using my own compiler, clang, ld yields the error, that the option rpath would be unknown.
lld: error: unknown argument: -rpath
Setting rpath to "", it works.
Do I loose important features, when setting rpath to empty string (e.g. problems in using packages) ?
Using julia-nightly, I had to find the right Artifact.toml first. I took it from here. Is this correct? I copied into the juliac-directory.
Compiling worked, however the executable gave an error. I used the example program:
function (@main)(args::Vector{String})::Cint
println(Core.stdout, "Hello, world!")
return 0
end
Here is the error message:
Please submit a bug report with steps to reproduce this fault, and any error messages that follow (in their entirety). Thanks.
