[Chicken-users] Incremental build, tricks or tips anyone?

[Matthew Welland]

I am updating some old code and the build broke because chicken-config no 
longer exists.  It took a while but I finally found that all I had to do was 
replace chicken-config with csc. I.e. "csc -cflags" in place of "chicken-config 
-cflags".

My question is, does anyone have a nicer way of doing this? I sometimes work 
on very weak machines such as single board computers and really appreciate 
build times of seconds instead of minutes when only one file has changed. 

src_code  := laedlib tc_laedlib re-route 
scm_files := $(addprefix ../scm/,$(addsuffix .scm,$(src_code)))
c_files   := $(addprefix src/,$(addsuffix .c,$(src_code)))
o_files   := $(addprefix src/,$(addsuffix .o,$(src_code)))

$(c_files): src/%.c: ../scm/%.scm ../scm/macros.scm
        chicken $< -output-file $@

$(o_files): src/%.o: src/%.c
        gcc -c $< `chicken-config -cflags` -o $@

$(src_code): %: src/%.o src/laedlib.o
        gcc src/$*.o src/laedlib.o -o $* `chicken-config -libs`
