Re: [Reduce-algebra-developers] [reduce-algebra:discussion] Reduce-Snapshot_6547.dmg does not work on macOS 10.15.7

[Jeff J. <tr...@po...>]

I’ve also managed to produce a new (unofficial) legacy build (this one actually done on a 10.13 system) …

It’s available at  https://github.com/reduce-algebra/homebrew-reduce-algebra/releases/download/Reduce_6547-x86_64-mac_10.13_highsierra-darwin17.7.0/Reduce_6547-x86_64-mac_10.13_highsierra-darwin17.7.0.dmg

The bad news: getting my Homebrew-based localbrew setup working on High Sierra was not for the faint of heart (and will only get degrade over time as there are no more updates for the operating system or toolchains.) Increasing the optimization level or enabling LTO, even with the latest Xcode available for this system, which is 10.1, results in a linker crash. As a result, the build targets all Intel processors generically, and uses standard optimizations.

The good news: it was done via localbrew, so the build environment is transportable.  If anyone wants to reproduce this for themselves on their own system, I can provide the whole build environment as a (rather large) archive.

Also, it might be possible to build newer versions of LLVM and Clang for better results, but really, these systems should be upgraded (or retired) soon.

I’ll add any new builds to https://github.com/reduce-algebra/homebrew-reduce-algebra/wiki/Package-Building
