undefined reference to `atsruntime_malloc_undef`

[CC (corrodedCrustacean)]

Hello,

I've recently discovered ATS and I'm following the introduction guide. I'm having trouble compiling with patscc (myatscc works, but only for a single source file) when a boxed value or a closure is defined.

Example:

#include "share/atspre_staload.hats"

val _ = '(0)

implement main0 () = print "hello"

When I compile with patscc I get the following error:

main_dats.c:(.text+0x10b): undefined reference to `atsruntime_malloc_undef'

I've installed ats2 with nix; according to patsopt I'm using version 0.4.2

You need the above flag when using patscc. It is the default for myatscc.
