[R] problems with R COMPILE in make

[Peter Holzer]

Dear R helpers

I have a problem with R COMPILE. While the Makefile consisting of the lines


SOURCES = imageio.c procbase.c readargs.c regSegs.c goodiesPH.c \
	  generalAnalysis.c edgeAggregation.c utilities.alga.c \
	  cs.parametrizing.c
tst.so: $(SOURCES)
	R SHLIB -o $@ $(SOURCES)


works fine, the Makefile with the target replaced by


imageio.o: imageio.c
	R COMPILE imageio.c


results in


cd /u/holzer/CurrentWork/algen/C/
make
R COMPILE imageio.c
make[1]: Entering directory `/users/u1/staff/holzer/CurrentWork/algen/C'
R COMPILE imageio.c
make[2]: Entering directory `/users/u1/staff/holzer/CurrentWork/algen/C'
make[2]: *** No rule to make target `w'.  Stop.
make[2]: Leaving directory `/users/u1/staff/holzer/CurrentWork/algen/C'
make[1]: *** [imageio.o] Error 2
make[1]: Leaving directory `/users/u1/staff/holzer/CurrentWork/algen/C'
make: *** [imageio.o] Error 2

Compilation exited abnormally with code 2 at Mon Sep  4 10:41:57


However, if I add $ as a typo (or at least, when I did it, it was just a typo)


$imageio.o: imageio.c
	R COMPILE imageio.c


everything works fine again. Do I miss something there?

I have one more question concerning compilation. I don't like the option
-Wcomment, so when I use -Wall for myself I add -Wno-comment. However, when
setting PKG_CFLAGS = -Wno-comment in file `Makevars' this doesn't help. I
suppose the reason is that the -Wall option comes then _after_ the
-Wno-comment option. Is there a way around that?

Thanks for any help
Peter
