Failed to build with erlang-23.0 version

[keerthanakalyan]

erlang-sd_notify failed to build with erlang version 23.0 with this error:

ERROR: sh(cc c_src/sd_notify.o -lsystemd -shared -L"/usr/lib/erlang/lib/erl_interface-4.0/lib" -lerl_interface -lei -o priv/sd_notify_drv.so) failed with return code 1 and the following output: /bin/ld: cannot find -lerl_interface

It seems that from version 23.0 of erlang, erl_interface is deprecated and removed. Could you please help is there a way to fix this issue?

I've just reproduced it. Hold on - I'll propose a fix soon.

@lemenkov are you working on it?

the problem is solved using rebar3:

RUN yum install -y https://dl.bintray.com/rabbitmq-erlang/rpm/erlang/23/el/7/x86_64/erlang-23.0.2-1.el7.x86_64.rpm
RUN wget https://s3.amazonaws.com/rebar3/rebar3 && chmod +x rebar3 && mv rebar3 /usr/local/bin/

I am still having problems with the build:

+ mkdir -p /home/sd/packaging/centos/BUILDROOT/erlang-sd_notify-1.0-1.el8.x86_64/usr/lib64/erlang/lib/sd_notify-1.0/ebin /home/sd/packaging/centos/BUILDROOT/erlang-sd_notify-1.0-1.el8.x86_64/usr/lib64/erlang/lib/sd_notify-1.0/priv
+ install -m 644 -p ebin/sd_notify.app /home/sd/packaging/centos/BUILDROOT/erlang-sd_notify-1.0-1.el8.x86_64/usr/lib64/erlang/lib/sd_notify-1.0/ebin
install: cannot stat 'ebin/sd_notify.app': No such file or directory

Ok I can compile using rebar3

 make compile
/usr/local/bin/rebar3 compile

@Gsantomaggio try the current version - I've switched away from NIF + added more tests.

@keerthanakalyan should be fixed now (see #35).

[lemenkov]

@Gsantomaggio could you please check that everything (including deb builds) still works on Debian?

[Gsantomaggio]

@lemenkov ok going to test

[Gsantomaggio]

[vagrant@localhost ~]$ NOTIFY_SOCKET=/run/systemd/notify erl

I'd say that it works, I had to change a couple of things.

built using rebar3

[lemenkov]

Ok, good. Closing this then.
