Minix 3.2.1 Makefile issue - minix

Question

I'm trying to run make with the below Makefile and I get the following error Makefile:2: *** missing separator. Stop.. This Makefile is the original file from Minix 3.2.1. I haven't done any changes. I check from the tabs problem. Can someone help me?
Thanks.

Answer 1

MINIX uses BSD make, which typically uses . to prefix its specific extensions. You installed GNU make, which has another set of extensions, not prefixed with .; furthermore you put GNU make ahead in the PATH order without renaming it. This is not going to take off.
What we usually do is to name GNU make under the name gmake or gnumake, and invoke it under that name when needed (for example, to compile packages from GNU ecosystem, or with a strong Linux bias.)
Another possibility you might consider is to install (if not already done) the bmake package, and uses that command when trying to compile programs which expect the BSD breed of make (this includes MINIX itself.)
