[ryandesign]

At https://github.com/ericchiang/pup/releases/tag/v0.4.0 there are downloads for i386 and x86_64 Macs but not arm64 Macs.

arm64 builds are available on brew. using it currently on M1

Hi. Came across the same issue and DID NOT want to use Homebrew. Here is my workaround... somewhat overkill as it can be used to rebuild all targets. I only used the darmin/arm64 output as this was my requirement; other targets have not been tested.

#! /bin/ksh
typeset version="0.4.0"

# Download the master repository (or the release tarball as desired)
git clone https://github.com/ericchiang/pup pup-$version
cd pup-$version

[[ -d dist ]] && rm -rf dist; mkdir dist

# Get all dependencies
for dependency in \
    github.com/{fatih/color,mattn/go-colorable} \
    golang.org/x/{net/{html,html/atom,html/charset},text/transform}
do GO111MODULE=auto go get $dependency; done

# List all platforms (exception list taken from release.sh)
go tool dist list | sed '/android|darwin\/arm|s390x|plan9\/arm/d; s/\// /' |\
while read os arch; do

    # Construct the target binary's name
    typeset binary=pup; [[ $os == windows ]] && binary+=.exe
    typeset arname=pup-$version-$os-$arch

    [[ $os == @(darwin|linux) && $arch == @(arm|amd)64 ]] || continue

    print -- "- building for operating system\`$os\` running on a \`$arch\` architecture"
    #go -- build -v -a -o dist/$binary github.com/ericchiang/pup &&
    GO111MODULE=auto GOOS=$os GOOARC=$arch CGO_ENABLED=0 \
    go build -v -a -o dist/$binary 1>&2 2>dist/$arname.log &&
    (cd dist; tar zcf $arname.tgz $binary && rm $binary)

done
