running Arch Linux and I I've been using erlang 18.3 from a custom build
instead of the Arch package. As of about a month ago, everything was
fine including dialyzer and xref. I didn't do any work with erlang for about a
month and went back to it this week and found that I could no longer get
dialyzer or xref to work. I get complaints about missing debug_info

Hi,<br class="gmail_msg">
<br class="gmail_msg">
I've installed erlang 19.2 from source code on my Gentoo Linux and I'm not<br class="gmail_msg">

configured with --without-javac --prefix=/usr<br class="gmail_msg">

I've also tried entering on erts/emulator and running make debug and tried<br class="gmail_msg">

<br class="gmail_msg">
I don't know if it is an issue with gentoo (both my gentoo machines have<br class="gmail_msg">
