Hi, I am using the FreeBSD make utility to build an automake based distribution. When I run make with a -j option (even -j1), it fails. Running make with a -j option makes the utility behave differently. The issue only arises with built sources (in my case, yacc generated C code), since those trigger the inference rule ".c.lo". Perhaps a solution would be to also generate explicit rules for built sources.
I have attached the output of running make with and without -j1. Regards, Pippijn van Steenhoven
