for the first time, i incorporated "vpath" into a makefile and it's
not working the way i expected it to based on the docs. the salient
bits of the makefile:
-------
vpath %.o ${BLDOSD}
${BLDOSD}/${TARGETDRV}: ${OBJS}
${CROSS_LD} $(LINKOPTS) $(LDFLAGS) -r $^ -o $@
${OBJS}: %.o: %.c
@if [ ! -d $(BLDOSD) ]; then mkdir -p $(BLDOSD); fi
${CROSS_CC} ${CPP_INCLUDES} ${DEFINES} -c $< -o ${BLDOSD}/$@
-----
in short, the sources are in the current directory, but i want to
build both the corresponding object files and the kernel driver in the
arch-specific ${BLDOSD} directory.
everything goes swimmingly (object files created nicely under that
directory), but in the rule for ${BLDOSD}/${TARGETDRV}, the "$^"
variable appears to contain just the short names of the object files
-- "vpath" is not taken into account despite the fact that the
dependencies testing seems to find them.
am i doing something trivially wrong here?
