Binary builds broken??

[bradwood]

I think the binaries for Linux x86 are broken:

bash-5.0# curl -LO https://github.com/tomnomnom/gron/releases/download/v0.6.0/gron-linux-amd64-0.6.0.tgz
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   661  100   661    0     0   3998      0 --:--:-- --:--:-- --:--:--  4006
100 2438k  100 2438k    0     0  4853k      0 --:--:-- --:--:-- --:--:-- 18.4M
bash-5.0# tar zxvf gron-linux-amd64-0.6.0.tgz
gron
bash-5.0# ./gron
bash: ./gron: No such file or directory
bash-5.0#
bash-5.0#

bash-5.0#

Or am I doing something stupid?

i386 build works fine, btw.

ryzen1> ./gron --help
Transform JSON (from a file, URL, or stdin) into discrete assignments to make it greppable

Usage:
  gron [OPTIONS] [FILE|URL|-]

Options:
  -u, --ungron     Reverse the operation (turn assignments back into JSON)
  -c, --colorize   Colorize output (default on tty)
  -m, --monochrome Monochrome (don't colorize output)
  -s, --stream     Treat each line of input as a separate JSON object
  -k, --insecure   Disable certificate validation
  -j, --json       Represent gron data as JSON stream
      --no-sort    Don't sort output (faster)
      --version    Print version information

Exit Codes:
  0	OK
  1	Failed to open file
  2	Failed to read input
  3	Failed to form statements
  4	Failed to fetch URL
  5	Failed to parse statements
  6	Failed to encode JSON

Examples:
  gron /tmp/apiresponse.json
  gron http://jsonplaceholder.typicode.com/users/1 
  curl -s http://jsonplaceholder.typicode.com/users/1 | gron
  gron http://jsonplaceholder.typicode.com/users/1 | grep company | gron --ungron

weird. this is in an alpine container, maybe it's that, but golang is zero deps, so will have to look a bit more... cheers...

Indeed this seems to be the case. This line reproduces the error:

$ docker run --rm -it alpine sh -c "apk add curl; curl -LO https://github.com/tomnomnom/gron/releases/download/v0.6.0/gron-linux-amd64-0.6.0.tgz; tar zxvf gron-linux-amd64-0.6.0.tgz; ./gron --help"
sh: ./gron: not found

I'm not a golang pro but it might be the case that the net package is responsible for this as mentioned in this stackoverflow answer. The net package is imported here, so gron might be affected by this.

A possible fix is to install the libc6-compat package and start gron with the env variables CGO_ENABLED=1 GOOS=linux:

$ docker run --rm -it alpine sh -c "apk add curl libc6-compat; curl -LO https://github.com/tomnomnom/gron/releases/download/v0.6.0/gron-linux-amd64-0.6.0.tgz; tar zxvf gron-linux-amd64-0.6.0.tgz; CGO_ENABLED=1 GOOS=linux ./gron --help"
Transform JSON (from a file, URL, or stdin) into discrete assignments to make it greppable
...

With this trick even the network I/O works without problems in my case:

$ docker run --rm -it alpine sh -c "apk add curl libc6-compat; curl -LO https://github.com/tomnomnom/gron/releases/download/v0.6.0/gron-linux-amd64-0.6.0.tgz; tar zxvf gron-linux-amd64-0.6.0.tgz; CGO_ENABLED=1 GOOS=linux ./gron https://api.github.com/users"
json = [];
json[0] = {};
json[0].avatar_url = "https://avatars.githubusercontent.com/u/1?v=4";
...

Hope this helps.
