Is the package broken with the latest rebar? #37

Closed rwngallego closed 4 years ago

rwngallego commented 4 years ago

I don't know if something has changed recently in rebar3 but currently it's not possible to get this working. Basically it cannot generate the syslog_drv.so driver. I've tried with different versions of elixir (1.6 / 1.10) but the result is the same.

In my case it's failing silently when compiling it as a dependency of ex_syslogger, it crashes when starting the application saying it could not found the syslog_drv driver. This looks like something similar to what is reported in this Pull Request: https://github.com/Vagabond/erlang-syslog/pull/36

rwngallego commented 4 years ago

@slashmili any ideas regarding this? It's actually breaking ex_syslogger.

slashmili commented 4 years ago

@rwngallego should be fixed by #38 and #36

rwngallego commented 4 years ago

Thank you very much! @slashmili are you planning to pin it in ex_syslogger and probably release a new version? Currently it's pinned to ~> 1.0.5 so it won't pick the latest erlang-syslog package (which now is 1.1.0).

slashmili commented 4 years ago

@rwngallego it's done https://hex.pm/packages/ex_syslogger/1.5.2

BrainBlasted commented 3 years ago

For some reason I still can't compile ex_syslogger 1.5.2 even with the latest version of syslog

You need to have erlang-dev package installed. Depends on your Linux flavour the name might be different.

BTW I just clone the project and compiled it without an issue. I should mention that I'm using asdf which installs the Erlang from source and compiles it.

BrainBlasted commented 3 years ago

I have the package installed.
