[erlang-questions] noproc file_server_2 when trying to load boot file

[Tristan Sloughter]

I have a .rel file and successfully create the boot/script files with systools:make_script but when I try to load the boot file it crashes with an error I can't find reference too anywhere online. Does anyone have an idea on what might be wrong?

$ erl

Erlang R14B04 (erts-5.8.5) [source] [64-bit] [smp:4:4] [rq:4] [async-threads:0] [kernel-poll:false]

Eshell V5.8.5  (abort with ^G)

1> systools:make_script("ctdemo", [local]).

ok

2> q().

ok

$ erl -boot ctdemo

{"init terminating in do_boot",{noproc,{gen_server,call,[file_server_2,{open,"./.erlang",[read]},infinity]}}}

Crash dump was written to: erl_crash.dump

init terminating in do_boot ()

In a nutshell, gen_server is complaining that process file_server_2 is
not running.

Check application:loaded_applications(), global_registered_names(),
appmon:start() for troubleshooting.

Hope this helps

Right, there isn't much I can do in that respect though since I can't get into a shell when loading the boot file.

Thanks,

Tristan

Though I can point out I actually have no file_server_2...

find ~/otp/ -name *file_server*

/home/dotcloud/otp/lib/kernel-2.14.4/src/file_server.erl

/home/dotcloud/otp/lib/kernel-2.14.4/ebin/file_server.beam

/home/dotcloud/otp/lib/kernel-2.14.5/src/file_server.erl

/home/dotcloud/otp/lib/kernel-2.14.5/ebin/file_server.beam

Hmm..

Nevermind, file_server module registeres as file_server_2:

-define(FILE_SERVER, file_server_2).      % Registered name

And I do see it loaded if I just run 'erl':

I fixed it... My release file was wrong. I had each app listed like:

{kernel,"2.14.5",load},

But once for each app I removed the ', load' and so just had:

{kernel,"2.14.5",load},

It works fine. Odd that systools:make_script creates a boot file fine though if it can't run it.

Thanks.

Grr, I meant, removed the ', load' and so just had:

{kernel,"2.14.5"},

I agree - systools:make_script should not create the boot file given this rel file. I'll add a ticket for future implementation. If anyone out there feels like doing the job, it will be much appreciated (and probably happen faster).
