Question

I have a variable like aaa/bbb/ccc/xxx.html and I need to create the path in the makefile. So I need to trim the location of the file from given variable and create the path using mkdir -p aaa/bbb/ccc. How can I get the location (aaa/bbb/ccc) from the variable (aaa/bbb/ccc/xxx.html) in the makefile?

GNU make’s dir function extracts the directory part of a path:

mkdirp -p $(dir $@)

generates the directory of the rule’s target, for example. Compare notdir and the GNU make manual.
