Error precompiling

[david-macmahon]

I can ]add Casacore (v 0.2.0) in Julia 1.8.3 , but when it tries to precompile it gives this error:

julia> import Pkg; Pkg.precompile()
Precompiling project...
  ✗ Casacore

ERROR: The following 1 direct dependency failed to precompile:

Here is my version info:

julia> versioninfo()
Julia Version 1.8.3
Commit 0434deb161e (2022-11-14 20:14 UTC)
Platform Info:
  OS: macOS (arm64-apple-darwin21.3.0)
  CPU: 8 × Apple M2
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-13.0.1 (ORCJIT, apple-m1)
  Threads: 1 on 4 virtual cores

Is this due to lack of M2 support in casacore itself? If it can't (yet) work, it would at least be nice to get a friendlier error message.

Hi David, thanks for the bug report.

The error you're seeing is because the casacorecxx binary for your system is missing. Now, I haven't tested this on an ARM system but from the build instructions I'm reading for casacore_jll and casacorecxx_jll, it seems like we should be building for a system if:

• it's not windows
• it's not freebsd
• and the libc is glibc (not musl)

So I think (??) actually this should work on MacOS/M{1,2}. I should get a chance this weekend to test properly on that hardware.

[torrance]

After a little investigation, it turns out the requirement libc == glibc essentially blocked macOS builds of casacorecxx_jll.

@david-macmahon I have posted a PR to enable macOS builds, and once this is accepted, I'll ask if you could update casacorecxx_jll and run the test suite to see how things go.

[torrance]

@david-macmahon The package has been rebuilt. From the Pkg REPL, run pkg> up Casacore and then run pkg> test Casacore and let me know if the test suite passes on macOS aarch64.

[david-macmahon]

Thanks! It passed the tests on my MacBook Air M2 laptop (see above for versioninfo() output). Here's what I got:

     Testing Running tests...

Great news!
