Hi,
Make cannot handle the word or path that contains space.
Here's a sample: (tested on 3.81 and 3.82)
--------------
INC=aa/hdr bb/hdr cc\ mgr/hdr
INC_FLAG=$(addprefix -I,$(INC))
N=$(words $(INC))
all: test
@echo INC_FLAG="$(INC_FLAG)"
@echo N=$(N)
test: $(INC)
@echo INC="$(INC)"
@echo INC="$^"
%: ;
--------------
Actual result:
--------------
INC="aa/hdr bb/hdr cc\ mgr/hdr"
INC="aa/hdr bb/hdr cc mgr/hdr"
INC_FLAG="-Iaa/hdr -Ibb/hdr -Icc\ -Imgr/hdr"
N=4
--------------
Expected result:
--------------
INC="aa/hdr bb/hdr cc\ mgr/hdr"
INC="aa/hdr bb/hdr cc\ mgr/hdr"
INC_FLAG="-Iaa/hdr -Ibb/hdr -Icc\ mgr/hdr"
N=3
--------------
Bug1: most internal function cannot deal with space that is escaped in the word.
Bug2: $^ loses the back-slash.
Best Regards
Liang, Jian
