[erlang-questions] determining what erts version a .beam was compiled with
Thu Jan 24 00:21:01 CET 2008
Interesting - I see the point about the compiler version being more salient than the erts vsn. The problem is other parts of my system depend on the erts vsn - perhaps in error. I need to think about this. Thanks for the info.
