Go Cross-Compile Script

go-build-all

#!/bin/bash
#
# GoLang cross-compile snippet for Go 1.6+ based loosely on Dave Chaney's cross-compile script:
# http://dave.cheney.net/2012/09/08/an-introduction-to-cross-compilation-with-go
#
# To use:
#
#   $ cd ~/path-to/my-awesome-project
#   $ go-build-all
#
# Features:
#
#   * Cross-compiles to multiple machine types and architectures.
#   * Uses the current directory name as the output name...
#     * ...unless you supply an source file: $ go-build-all main.go
#   * Windows binaries are named .exe.
#   * ARM v5, v6, v7 and v8 (arm64) support
#
# ARM Support:
#
# You must read https://github.com/golang/go/wiki/GoArm for the specifics of running
# Linux/BSD-style kernels and what kernel modules are needed for the target platform.
# While not needed for cross-compilation of this script, you're users will need to ensure
# the correct modules are included.
#
# Requirements:
#
#   * GoLang 1.6+ (for mips and ppc), 1.5 for non-mips/ppc.
#   * CD to directory of the binary you are compiling. $PWD is used here.
#
# For 1.4 and earlier, see http://dave.cheney.net/2012/09/08/an-introduction-to-cross-compilation-with-go
#

# This PLATFORMS list is refreshed after every major Go release.
# Though more platforms may be supported (freebsd/386), they have been removed
# from the standard ports/downloads and therefore removed from this list.
#
PLATFORMS="darwin/amd64" # amd64 only as of go1.5
PLATFORMS="$PLATFORMS windows/amd64 windows/386" # arm compilation not available for Windows
PLATFORMS="$PLATFORMS linux/amd64 linux/386"
PLATFORMS="$PLATFORMS linux/ppc64 linux/ppc64le"
PLATFORMS="$PLATFORMS linux/mips64 linux/mips64le" # experimental in go1.6
PLATFORMS="$PLATFORMS freebsd/amd64"
PLATFORMS="$PLATFORMS netbsd/amd64" # amd64 only as of go1.6
PLATFORMS="$PLATFORMS openbsd/amd64" # amd64 only as of go1.6
PLATFORMS="$PLATFORMS dragonfly/amd64" # amd64 only as of go1.5
PLATFORMS="$PLATFORMS plan9/amd64 plan9/386" # as of go1.4
PLATFORMS="$PLATFORMS solaris/amd64" # as of go1.3

# ARMBUILDS lists the platforms that are currently supported.  From this list
# we generate the following architectures:
#
#   ARM64 (aka ARMv8) <- only supported on linux and darwin builds (go1.6)
#   ARMv7
#   ARMv6
#   ARMv5
#
# Some words of caution from the master:
#
#   @dfc: you'll have to use gomobile to build for darwin/arm64 [and others]
#   @dfc: that target expects that you're bulding for a mobile phone
#   @dfc: iphone 5 and below, ARMv7, iphone 3 and below ARMv6, iphone 5s and above arm64
#

I found it, just run: go tool dist list

Nice @makeworld-the-better-one! I knew there were others at the time I wrote this many many years go. Just those edge cases were not needed.

Humm, you know, it's about time I distribute this via more public means.

Let me test out and update to a few more that makes sense, and then I make make a GoLang lib for it with CICD that keeps it updated (I love GitHub Actions these days).

@eduncan911 That'd be awesome, thanks! Just let me know via this thread if you could, once it's ready.

Alright well I just wrote a script that is very similar to yours, but it uses go tool dist list instead, so it never goes out of date. I tested it and it seemed to work fine. https://gist.github.com/makeworld-the-better-one/e1bb127979ae4195f43aaa3ad46b1097

mkdir build
for f in $(find . -executable -type f | xargs file | grep ELF | awk '{print $1}' | sed 's/://g' | sed 's/\.\///g'); do zip "$f".zip "build/$f"; done

For zip every file in a different zip under the build folder

@alessiosavi I think this is simpler and works on git bash on windows

IFS=$'\n'
for f in $(ls -1 -v build)
do
    zip "$f".zip "build/$f"
done
