[comp.os.minix] Dmake for Minix

mirage1@gpu.utcs.utoronto.ca (Cyber City) (02/21/91)

I was able to compile the DMAKE utility on my PC 286 with Minix 1.5,
but it was necessary to replace the libc.a module tmpnam.o (for BCC)
with a more standard tmpnam.o, which is includes the tempnam() function.
I edited the DSB version below, replacing u_int with "unsigned int" and
so on, and it seems to work well, except for a little conflict with
the declaration of tempfile() in tempfile.c (estdio lib module).

The tempnam() function is pretty standard in other C libraries I've seen,
so perhaps this could be a permanent replacement.

To make DMAKE, just type "make sysvr3", using your new libc.a.

Here are some places to obtain DMAKE:
