make and would like to create a Makefile for cross-building a C-project, where all the derived files (generated assembler and object files) are stored in a dedicated sub-directory. The cross-toolchain I am using is devel/cc65 for the venerable C-64.My project directory looks like this:
Code:
Makefile
change_border.s
hello.c
music.c
ld.cfg # Linker configuration fileFor putting all generated files into a dedicated sub-directory, the
.PATH target came into my mind. Here is what I came up with so far for the Makefile:
Code:
# Name of the directory where to store all derived files.
OUTPUT = output
# All the suffixes that are relevant for this project.
.SUFFIXES: .s .c .o
# Search for .s files in the current and the $OUTPUT directory.
.PATH.s: ./ ./${OUTPUT}
# Search for object files in the $OUTPUT directory.
.PATH.o: ./${OUTPUT}
# Transformation rule how to compile C files into assembly files.
# The generated .s file is stored in the $OUTPUT directory.
.c.s:
cl65 -C ld.cfg -S -o ${OUTPUT}/${.PREFIX}.s ${.IMPSRC}
# Transformation rule how to turn assembly files in to object files.
# Note how the object files are stored in the $OUTPUT directory.
.s.o:
ca65 -o ${OUTPUT}/${.PREFIX}.o ${.IMPSRC}
# All the objects needed for building the executable.
OBJS = hello.o music.o change_border.o
# The executable depends on the $OUTPUT directory and the objects.
hello.prg: ${OUTPUT} ${OBJS}
ld65 -C ld.cfg --mapfile ${OUTPUT}/${.PREFIX}.map \
-o ${OUTPUT}/${.TARGET} ${.ALLSRC} c64.lib
# How to create the $OUTPUT directory.
${OUTPUT}:
mkdir -p output
# Cleaning everything should mean just to remove the $OUTPUT
# directory.
clean:
rm -rf ${OUTPUT}When running
make -r it gives the following output and error:
Code:
mkdir -p output
cl65 -C ld.cfg -S -o output/hello.s hello.c
ca65 -o output/hello.o hello.s
Fatal error: Cannot open input file 'hello.s': No such file or directory
*** Error code 1
Stop.
make: stopped in /usr/home/hsebert/Projects/IRQ_loaderca65 -o output/hello.o ./output/hello.s, but the .PATH directive seems to have no effect.Any ideas?
