zstd @1.5.6: does not respect macos setting on build

[lukaso (Lukas Oberhuber)]

Even after setting this, the build still leaves zstd build for the MacOS version it is running on:

  echo 'macosx_deployment_target 10.13' | tee -a ${PREFIX}/etc/macports/macports.conf
  echo 'macosx_sdk_version 10.13' | tee -a ${PREFIX}/etc/macports/macports.conf

From otool -l

Load command 10
      cmd LC_BUILD_VERSION
  cmdsize 32
 platform 1
    minos 13.0
      sdk 13.3
   ntools 1
     tool 3
  version 857.1

It looks like this bug was introduced upstream in v1.5.6

Do you check each library manually or is there an easy way to audit all of the libraries that your program depends on to find the ones that have this problem?

[lukaso (Lukas Oberhuber)]

I’ve written a program to check it (or should I say, chat-gpt wrote me a program to check it.) Happy to upload if it would be helpful.

But in this instance it came via a bug report as I’d not incorporated the script into the CI system.

Similar to #69947

[ryandesign (Ryan Carsten Schmidt)]

I was just curious for my own purposes whether you had to parse the otool -l output or if there was a better API for getting just the interesting values, and how you were collecting the list of libraries that you needed to check.

[lukaso (Lukas Oberhuber)]

@ryandesign here's the script. Sorry, should have posted sooner! ​https://gitlab.gnome.org/Infrastructure/gimp-macos-build/-/blob/master/scripts/validate_min_os.py?ref_type=heads

I parse otool -l to answer your actual question.

how you were collecting the list of libraries that you needed to check

I use a bunch of packaging scripts, which, to make a long story short, follow all the library dependencies from GIMP on down and copy them into the relevant directories, while fixing up @rpaths and doing a bunch of other admin. I then run this script on all libraries that have been copied in and which will eventually be packaged into GIMP.app.

here's the upstream issue (should have posted as well): ​https://github.com/facebook/zstd/issues/4038

[lukaso (Lukas Oberhuber)]

Fix submitted and approved (but not merged): ​https://github.com/facebook/zstd/pull/4191

[lukaso (Lukas Oberhuber)]

From zstd. Closed #4038(​https://github.com/facebook/zstd/issues/4038) as completed via [d0fe334](​https://github.com/facebook/zstd/commit/d0fe334c8552edb764b853854037697c6710fa64).

I think we'll have to wait on 1.5.8 however to get the fix.
