makefile - GNU Make: "dir not expected at this moment" -

i have makefile including following lines:

buildrepo:     @$(call make-repo)  define make-repo    dir in $(c_srcs_dir); \    \     mkdir -p $(objdir)/$$dir; \    done endef 

on line commands for dir in $(c_srcs_dir); \ following error message:

"dir not expected @ moment" make: *** [buildrepo] error 255 

i using gnu make.

can tell me going wrong?

actually for ... in ... ; ... done statement unix command not gnu make command, therefore guess using windows machine (or other one). have find equivalent system.

but gnu make has foreach function works :

$(foreach dir,$(c_srcs_dir),mkdir -p $(objdir)/$(dir);) 

also note in specific case (not related gnu make windows) can create dirs without for/foreach loop, :

mkdir -p $(addprefix $(objdir)/,$(c_srcs_dir))
