Bug report: Make cannot handle the word or path that contains space

[Liang, Jian]

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
