[erlang-questions] 1 failed test when installing Erlang 19.2 on Ubuntu using building method

[Olivier Stas]

Hi everyone,

I installed erlang/otp 19.2 today on a Ubuntu laptop, following 
carefully instructions.
When executing suite test, one failed. I have no idea if that particular 
test is important or not as I'm a newbee for Erlang. But an error is 
never normal, so I share.
Nevertheless I finished the installation, without knowing if I will get 
into trouble at sometime or not because of that.

Of course I'm available to give as many information as needed and 
proceed with any test or whatever if it may helps.

So, Ubuntu 16.04 up to date, core i7.
Erlang downloaded: http://erlang.org/download/otp_src_19.2.tar.gz

The command issued to launch tests:

|$ERL_TOP/bin/erl -s ts install -s ts smoke_test batch -s init stop |

|And the log file generated:|

Issue is as mentioned at line 624. Here is the test case with that line:

620: *t_gethostnative*(Config) when is_list(Config) -> 621: %% this will 
result in 26 bytes sent which causes problem in Windows 622: %% if the 
port-program has not assured stdin to be read in BINARY mode 623: %% 
OTP-2555 624: *case inet_gethost_native:gethostbyname*( 625: 
"a23456789012345678901234") of 626: {error,notfound} -> 627: ok; 628: 
{error,no_data} -> 629: ok 630: end.

Thanks,

Olivier
