macOS Illegal instruction: 4 about ugrep HOT 8 CLOSED

I will remove option -P from the prebuilt binaries altogether.

EDIT:

For those that want a MacOS version of ugrep with all features enabled, you may want to use Homebrew to install the latest release:

$ brew install https://raw.githubusercontent.com/Genivia/ugrep/master/Formula/ugrep.rb

See #21.

END EDIT

To install pcre2 on Mac, use macports:

$ sudo port install pcre2

Or if you prefer homebrew:

$ brew install pcre2

If you don't have bzip2-dev and lzma-dev (check with ls /usr/lib/libbz2* /usr/lib/liblzma*, then try this:

$ sudo port install bzip2
$ sudo port install xz

from ugrep.

maybe I found the reason: Illegal instruction: 4
I used an mac computer for testing and the latest version of ugrep that works on it - 1.7.6,
all others include the latter give an error - Illegal instruction: 4

from ugrep.

It could be an AVX problem. I've now updated bin/macosx/ugrep in the master branch to use SSE2 only.

Works on new mac with Mojave/Catalina, but on old with High Sierra - Illegal instruction: 4

from ugrep.

We should create a homebrew formula for ugrep instead of sharing the binary, because it's best to use ugrep's optimizations for speed. I'll get to that in a few days.

I've created a homebrew formula. However, the brew audit command says "repository not notable enough (<30 forks, <30 watchers and <75 stars)". Well, this is not surprising as the repo is relatively quite new.

It seems we need more stars and forks to release a homebrew formula.

Any help is appreciated.

See "help wanted" #21

from ugrep.

For those that want a MacOS version of ugrep with all features enabled, use brew tap https://github.com/Genivia/ugrep to clone ugrep on your system with homebrew tap. Then brew install ugrep to install ugrep . I'll create a homebrew formula later, see #21.
