Hi everyone. We intend to use julia to create a fully self-contained, completely pre-compiled library for integration in a larger software. I did read several posts, watched YouTube, etc. – there’s a lot but also quite scattered information. Also, there’s (for me) still the confusion about PackageCo…

Yeah, it’s still quite hard and on the bleeding edge right now. Julia dynamically links to lots of libraries — both at startup and dynamically loaded. A few quick notes: PackageCompiler has the smarts to get the rpaths right and gather all the artifacts and other libraries. The current juliac.jl …

If your functions are simple enough you may find StaticCompiler.jl as an alternative.

I am also very interested in this and actively trying to get a library to trim and distribute. I am currently able to generate the “.so” file and have filtered out the required libraries “by hand” (going through one-by-one in the RPATH and checking if renaming them breaks the executable). Now when I…

I was able to strip out libstdc+±6.dll by the way, which seems to take up a majority of your memory. I still have BLAS bundled though (35MB), and getting rid of that is turning out to be tricky, for instance because it is challenging to track from where BLAS is actually called.

I’m similarly trying to figure out (by reverse engineering PackageCompiler, among other things) what the minimum set of DLLs is for a given program. I’d be interested in knowing what the minimum set of these is for the Julia language to fully work – I don’t believe it is the full distro you get on a…

I have now managed to also compile it and run everything on a clean podman VM. For the artifacts, as a crutch I also compile with PackageCompiler.jl and then just copy over the artifacts that are bundled there. Probably I could go in and figure out how PackageCompiler.jl constructs the artifacts bun…

I think in my many follow-ups and edits, my current pain point was lost. So I can compile the “hello world” example, but when trying to load the library in julia, I get an error about a missing entrypoint named ijl_autoinit_and_adopt_thread. However, when calling the library from Go, for example, …

Update: Julia not being able to call juliac-compiled library: See the progress on the issue linked above: This is a known limitation currently, as each system image thinks it’s the only one that should be loaded. Soon we will have a workaround for this by allowing you to give a library its own pr…

Another update, this time about Artifacts. I think to remember I read something about juliac and Artifacts, and that PackageCompiler has functionality to collect all required Artifacts – but don’t remember where. Any pointers are welcome, thanks! Artifacts are the binary dependencies (compiled shar…

Creating fully self-contained and pre-compiled library

General Usage

Depending on your use case, this might work: put your julia code inside an AppBundler.jl app and have your library call that. No trim functionality, unless you delete files manually.
