How to solve undefined reference to dynloadflag?

My exact error link-time error is:

print.o: In function `_057_home_057_brandon_057_workspace_057_fsh_057_print_056_dats__dynload':
/home/brandon/workspace/fsh/print_dats.c:315: undefined reference to `_057_home_057_brandon_057_workspace_057_fsh_057_print_056_dats__dynloadflag'

The contents of print.dats is simply:

typedef FormatStruct = $extype"Format"

vtypedef Format(ll: addr) = (FormatStruct @ ll | ptr ll)

extern fun fmtputc{ll: addr}(fmt: Format(ll), cc: int): void = "mac#"

I have another dats file (main.dats) that doesn't seem to cause this issue. Is there some ATS library that needs to be added to LDFLAGS?

Every DATS file in ATS is considered a module of some sort, which needs to be initialized. If no initialization is needed, then you need to add the following line in this DATS file

#define ATS_DYNLOADFLAG 0

Otherwise, you need to have a line like the following one

#dynload "/path/to/foo.dats"

in the main file where this module is used.
