"exec format error"

[viperfx]

Hi,

I am using OSX and I get the following issue when trying to run the make -C server/envs/dev command

make -C ../..
go generate dmitryfrank.com/geekmarks/...
go build --race -i dmitryfrank.com/geekmarks/server/cmd/geekmarks-server
docker build -t docker.io/dimonomid/geekmarks-server .

Hi,

Unfortunately I don't have any Mac machine to test it on, and from what I know, there are some pecularities in how docker works on Mac. Please see this docker issue: moby/moby#26665 does that help in your case?

You can also consider running geekmarks binary directly, without docker (and you'll also need postgresql daemon running), as @mariusrugan explained in his comment to another (unrelated) issue #5 (comment)

yeah i found the same issue but at that point i was figuring out the correct go/src/ path for the whole thing to actually start building.
i'm looking now but can't find an answer to what is happening right now.

same error
standard_init_linux.go:178: exec user process caused "exec format error"
googling for it leads to:
docker-library/mysql#228

• 1. platform incompatibility ? can't be the case
     i'm building with
     go generate dmitryfrank.com/geekmarks/...
go build dmitryfrank.com/geekmarks/server/cmd/geekmarks-server
• 2. issue with Dockerfile entrypoint ?

Cutting now down everything but geekmarks in the make-to-docker up chain; Even with a very flat Dockerfile

FROM golang:1.7
ADD geekmarks-server /geekmarks-server

build with docker build .
run with docker run -i -t #IMAGE_HASH# bash
i get:

root@fcd6040eeee4:/# ./geekmarks-server bash: ./geekmarks-server: cannot execute binary file: Exec format error

maybe @dimonomid you have more experience running it ?

#EDIT#
moby/moby#26665 (comment) running similar command, runs just fine.

docker run --rm -ti golang:latest sh runs fine
docker run --rm -ti golang:1.7 sh runs fine

#EDIT 2#
my fault, i was a bit too optimistic on " platform incompatibility ? can't be the case "
pull request #10 fixes the issue by indicating x-platform compatibility (see server/Makefile)
CGO_ENABLED=0 GOOS=linux GOARCH=amd64
the rest is sugar-coating (waiting for postgres to be up)
