GNU Make: "dir not expected at this moment"

I have a makefile including the following lines:

buildrepo:
    @$(call make-repo)

define make-repo
   for dir in $(C_SRCS_DIR); \
   do \
    mkdir -p $(OBJDIR)/$$dir; \
   done
endef

On the line with the commands for dir in $(C_SRCS_DIR); \ I get the following error message:

"dir not expected at this moment"
make: *** [buildrepo] Error 255

I am using GNU make.

Can anybody tell me what is going wrong?

Actually this for ... in ... ; do ... done statement is a Unix command not a GNU make command, therefore I guess you are using a Windows machine (or any other one). You have to find the equivalent for your system.

But GNU make has a foreach function which works like this : 

$(foreach dir,$(C_SRCS_DIR),mkdir -p $(OBJDIR)/$(dir);)

Also note that in your very specific case (not related to GNU make but to Windows) you can create all the dirs without a for/foreach loop, just like this : 

mkdir -p $(addprefix $(OBJDIR)/,$(C_SRCS_DIR))
