Recently I try to build a rabbitmq-server by instruction that described in https://www.rabbitmq.com/build-server.html
but i failed.

Environment

  • Macos version: 10.14.6
  • Source code: tags/v3.8.2
  • Python version: 2.7.17
    • simplejson version: 3.17.0
  • Erlang version: 22.2.1
  • GNU make version: 4.2.1

Steps to reproduce

cd rabbitmq-server
make -j1 V=1

Error description

GNU make reports a error while building depends packages.
first error message say:

env: escript\r: No such file or directory
/Users/changrunqing/Projects/rabbitmq-server
{“init terminating in doboot”,{undef,[{rmemo,start,[],[]},{erl_eval,do_apply,6,[{file,”erl_eval.erl”},{line,680}]},{erl_eval,exprs,5,[{file,”erl_eval.erl”},{line,126}]},{init,start_it,1,[]},{init,start_em,1,[]},{init,do_boot,3,[]}]}}^M
init terminating in do_boot ({undef,[{rmemo,start,[],[]},{erl_eval,do_apply,6,[{},{}]},{erl_eval,exprs,5,[{},{_}]},{init,start_it,1,[]},{init,start_em,1,[]},{init,do_boot,3,[]}]})^M
^M
Crash dump is being written to: erl_crash.dump…done^M

Two things are strange:

  1. there’s a \r in the end of the first error line, it seems that some script use CRLF as line ending, so script can not run, and i have tested that escript can work correctly.
  2. the rest of the error message is ending with CRLF(^M).

Attachment

any suggestions are welcome.

Hello,

We do not recommend that users build RabbitMQ from source code. Please use one of the official packages. On OS X, I usually use the generic-unix package for testing:


The output you have provided shows what the problem is:

env: escript\r: No such file or directory

You either don't have Erlang installed or it is not installed correctly, since the escript program should be in your PATH. I have no idea why you are seeing those line endings. I have never seen it on OS X.

Thanks,
Luke

Thanks for your reply, the reason that i build from source is i need modify some code.
And I tested that Erlang was Installed correctly.

which escript
> /usr/local/bin/escript
which erl
> /usr/local/bin/erl

It's one of the dependencies that fails to build as far as I can tell, specifically
when erlang.mk tries to patch a rebar-managed project. That's the only reference of "rmemo" that I could find [1].

the "escript\r" part makes me wonder if there's a bogus newline character of sorts.

You can try a Debian VM or container to compare. I'm on macOS Catalina but cannot reproduce.

Thanks a lot!. i found the reason. as your suggestion, i try to build deps one by one.
i found even the first rabbitmq-common failed to build, with same error msg. so i try to find is there have some files with CRLF ending,
and i found all script with CRLF ending, i think back i did a config on git, set autocrlf = true(reason was complex), so i turn it to false.
build sucess!
thanks again for everyone's help.

Oh, it's certainly good to know that local git configuration can affect build stability.

Thank you for reporting back to the list!
