I attached a Makefile and t.cpp. Put these into a directory which has a space
in its name. Run make, notice that it works correctly.
Now, at line 14, change the order-only dependency to "| $$(ROOT)/build" (add a
$ in front). Delete the "build" directory, and try again make. This time make
will fail a "No rule to make target '<path>/sp bug/build/t.o' message.
If I use the -d switch to make, I see this:
Considering target file 'all'.
File 'all' does not exist.
Looking for an implicit rule for 'all'.
No implicit rule found for 'all'.
Considering target file '<path>/sp bug/build/t.o'.
File '<path>/sp bug/build/t.o' does not exist.
Looking for an implicit rule for '<path>/sp bug/build/t.o'.
Trying pattern rule with stem 't'.
Trying implicit prerequisite '<path>/sp\'.
Trying pattern rule with stem 't'.
Trying implicit prerequisite '<path>/sp\'.
Looking for a rule with intermediate file '<path>/sp\'.
Avoiding implicit rule recursion.
No implicit rule found for '<path>/sp bug/build/t.o'.
Finished prerequisites of target file '<path>/sp bug/build/t.o'.
Must remake target '<path>/sp bug/build/t.o'.
make: *** No rule to make target '<path>/sp bug/build/t.o', needed by 'all'.
Stop.
It seems that even though "sp\ bug" has the space escaped, it is still split
into two parts, "sp\" and "bug".
