Try setting RPATH (avoid need of: export DYLD_LIBRARY_PATH)

Yes the option using ... makes the tree non-relocatable, this is only for a fixed install in, say, /opt/local or /usr/local.

  set(CMAKE_INSTALL_NAME_DIR "@rpath")
  set(CMAKE_INSTALL_RPATH "@loader_path/../lib")  # self relative LIBDIR
  set(CMAKE_SKIP_INSTALL_RPATH FALSE)          # don't skip the full RPATH for the install tree

Maybe this could be set using: cmake . -DCMAKE_INSTALL_NAME_DIR="@rpath" -DCMAKE_INSTALL_RPATH="@loader_path/../lib" -DCMAKE_SKIP_INSTALL_RPATH=FALSE. This could potentially fix libprimecount.so not found if the user has not set DYLD_LIBRARY_PATH="/usr/opt/..."

If I install primecount from source on macOS using Homebrew, using the defaut instructions, all seems to work as it is now.

@dimpase By luck I have figured out how to use the default AppleClang C/C++ compiler with OpenMP today. Therefore I have just done a new release of homebrew-primecount with this change. The primecount installation time using homebrew has now been significantly reduced as homebrew's LLVM/Clang does not need to be downloaded + installed anymore.

I also think that I have fixed the RPATH issue. I am now using the -DCMAKE_INSTALL_RPATH=#{rpath} option that is also used by the core packages provided by homebrew (e.g.: https://github.com/Homebrew/homebrew-core/blob/master/Formula/primesieve.rb#L20)

I have tested the new primecount version on both an Intel Mac (macOS 11.6) and an Apple Silicon Mac (macOS 12.1) and it worked fine for me.

Should you try putting primecount in Homebrew's core, too?

[kimwalisch]

I tried submitting primecount to homebrew about 5 years ago and it was rejected because primecount was not notable enough. If I remember correctly they required 100 GitHub stars & 30 people watching the repo on GitHub (primecount currently only has 20 watchers). It is difficult for primecount to meet the high homebrew minimum requirements:

Versioned formulae submitted should be expected to be used by a large number of people. If this ceases to be the case, they will be removed. We will aim not to remove those in the top 3,000 install_on_request formulae.

Because of this primecount is currently only a homebrew tap.

[dimpase]

They don't have GH stars and watchers requirements any more, as far as I see. Perhaps, one should wait until primecount makes it into Debian (it's almost there).

[kimwalisch]

OK, I'll try to submit it again to homebrew/core once it is in Debian.

@dimpase primecount is now a homebrew-core formula, see: https://github.com/Homebrew/homebrew-core/blob/master/Formula/primecount.rb. Hence primecount can now be installed using brew install primecount on macOS.

Thanks, we're adding this on https://trac.sagemath.org/ticket/33805
