![]() For ArchLinux and Manjaro: pacman -S erlang.For Ubuntu and Debian: apt-get install erlang.For MacPorts on macOS: port install erlang.For Homebrew on macOS: brew install erlang.Most OS package managers provide pre-built binary packages. They help to remove the differences between Erlang/OTP releases and the OS you are compiling on. You can also use third-party tools such as Kerl or asdf to compile Erlang. So always make sure to read the build and install instruction of the release you are compiling. If you clone the release from git, there may be some additional steps needed depending on which version of Erlang/OTP you are compiling. In a nutshell to install a pre-built archive you need only do. At the very least there should be an open issue so this doesn’t get buried by other development activities.You can build Erlang from source on your own, following the building and installation instructions. I was very happy with a performant, bundled SWIP application that meant I didn’t have to touch the terminal app, but I’m not all that satisfied with the status quo. ![]() Since I’m incapable of building binaries I can trust, all I see is a significant performance regression on a supposedly supported platform that’s persisted for a year. And I think you’re asking a lot for non-C professionals to start building an application as complex as SWIP from source. That’s all on me, but don’t expect it to change. I’m quite capable of blindly copying commands to the terminal but have no idea what’s happening under the covers.

Installing dependencies is described at Building SWI-Prolog on MacOSX. So any prospect of getting the new Mac fat binary releases to perform as well as old ones on Mac Intel? If I set the optimise flag to ``true`, it’s 1.23 vs. Welcome to SWI-Prolog (threaded, 64 bits, version 8.5.20-DIRTY) for legal details.įor built-in help, use ?- help(Topic). SWI-Prolog comes with ABSOLUTELY NO WARRANTY. Welcome to SWI-Prolog (threaded, 64 bits, version 8.4.1) Using the standard bench mark suite in the release on my Intel Mac: ?- version. The fat Mac binaries supporting Apple silicon run significantly slower on Intel Macs than the old Intel only binaries. I’ve referred to this issue a few times before in other threads but don’t think I ever saw an explanation/resolution.
