This file describes what the components of the "Makefile" mean. The
"Makefile" describes how to construct the "CRender" program, it is used by
a tool called "make" to build the program whenever you edit one of the
source files.
The "Makefile" is split into individual items, each item describes a
file, so the item that looks like
CRender: render.o aif.o
blink with $*.blink
tells "make" that the "CRender" file needs to be remade each time
"render.o" or "aif.o" is changed, and that you can construct the file with
the command "blink with $*.blink". The "$*" sequence is automatically
translated by "make" into "CRender" so the actual command that will be
used is
blink with CRender.blink
if the "CRender.blink" file has not been created you can create it with
the command
make $*.blink
issued to the CLI. The next part of the "Makefile" tells "make" about the
".o" files
render.o: 3D.h
aif.o: 3D.h menustrip.h
these items just tell "make" to recompile "render.c" each time "3D.h" is
changed, and "aif.c" each time "3D.h" or "menustrip.h" is changed. We do
not need to give any more information because "make" knows how to normally
compile ".c" files into ".o" files.
The final item in the file tells make how to construct ".o" files from
".c" files
.c.o:
NorthC -Ot:$*.s $*.c
top t:$*.s t:$*.s1
a68k -g -q -O$*.o t:$*.s1
delete t:$*.s t:$*.s1
again the "$*" will be replaced by the root filename. The reson for
adding this is that we want the system to optimise the code that the
compiler has produced.
For more detail of how "make" works see the documenation in the ":bin"
directory on the "NorthC" disk.
