Build failed raspbian stretch

[sushrut91]

I am getting a compilation error with the CoAP module when I try to compile the version 2.1.0 on Raspbian stretch running on Raspberry pi model B V1.2. Any help is highly appreciated. Thanks

It is the compile error. Which erlang/otp version do you use?

[sushrut91]

Erlang/OTP 19 [erts-8.2.1] [source] [smp:4:4] [async-threads:10] [kernel-poll:false]

Eshell V8.2.1 (abort with ^G)

[gilbertwong96]

gen_coap needs the leex module in order to compile. Normally this module is installed with Erlang in a complete installation. But it was wrong on Raspberry pi. So I recommend you to compile and make install erlang/otp 20 yourself on your Raspberry pi and compile master branch of emq-relx . I'm not familiar with Raspberry pi. Maybe it could help you.

@sushrut91, The build failure has been fixed after merging this PR https://github.com/emqx/emqx-coap/pull/83 Now,it should be ok. Please try again.

Thanks for your help, with Erlang/OTP 20 the compilation error went away however I am getting this error when I try to run the /bin/emqttd

sudo ./emqttd console

[gilbertwong96]

Erlang/OTP 20 does not accept "-smp disable". Did you compile version 2.1.0 of emq-relx which only supported on Erlang/OTP 19 ?

If you use Erlang/OTP 20, please checkout v2.3.11 tag of emq-relx and rebuild it again.

[sushrut91]

I switched to v2.3.11 with Erlang/OTP 20 and now things are working fine. Thanks for your help !
