'exec format error' when using binary from 0.6.3-alpha1 release

[stephenchu]

OS: macOS Sierra 10.12.6

Darwin a.b.c.d 16.7.0 Darwin Kernel Version 16.7.0: Wed Feb 27 00:29:57 PST 2019; root:xnu-3789.73.43~1/RELEASE_X86_64 x86_64

When I tried to download the pre-built binary, I am unable to run it:

› curl -fsSL -o docopts https://github.com/docopt/docopts/releases/download/v0.6.3-alpha1/docopts && chmod +x docopts && ./docopts --help
zsh: exec format error: ./docopts

› file ./docopts
./docopts: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped

Thanks.

Hi @stephenchu

prebuilt binaries are for GNU/Linux only, not for mac OS.
I should write it somewhere, sorry.

I built this for you with golang cross compile built-in on my Linux 64 bits OS.

$ make docopts-OSX
env GOOS=darwin go build -o docopts-OSX docopts.go

I don't have any mac OS nearby, it is not tested.

I uploaded it here: docopts-OSX

Here is the checksum to verify the downloaded binary.

$ sha256sum docopts-OSX
4981ea3995641d3b00f5ee760ea404598734aa2320f81a6ef8b9c569a865d8c1  docopts-OSX

does it helps?

In the file:

https://github.com/docopt/docopts/blob/master/.travis.yml

There is command to build for mac OS, if you want to try on your computer

Of course, you will need to setup a build environment for golang on you computer.

brew update
brew install bash
bash --version ; type bash
go get github.com/docopt/docopt-go
go get github.com/docopt/docopts

another option would be to retrieve the travis built binary.

Hope that helps.
