Creating, Distributing, and Testing Julia Packages with Binary Dependencies

JuliaCon Workshop, June 21 2016

Tony Kelman (@tkelman)

  • So you wrote or want to use a Julia package that calls into C or Fortran.
  • How do you go from "ccall works on my machine" to making your package easy to install for anyone?
  • You want Pkg.add("MyPackage") to find, build, or download a copy of the library that will work on:
    • Linux (many distributions, Ubuntu, CentOS, etc) on x86_64 architecture
    • Mac OS X
    • Windows (7,8,10, with 64 bit and 32 bit Julia)
    • More exotic OS or architecture combinations (won't cover in much detail)
  • Ideally without requiring the user to have root/admin permissions

Now onto the (other) complicated part!

  • Upload the binary somewhere
    • GitHub releases, simplest choice
    • Automation using Travis CI (if we need to change or rebuild often)
  • Repeat for other common platforms
  • OS-specific caveats (there are many)
  • Get the binary downloaded to the user's machine at package install time
  • Add a fallback automatic from-source build for exotic OS/architectures
