Makefile define the problem-CodePudding

 
Source: Ng Ho F1=No 
Dir:=/cc/test/CPP/SRC 
Define the VAR 
Lib=$(foreach L, $(source) and $(dir)/$(L) Class. Cc) 
SRC=https://bbs.csdn.net/topics/$(foreach L, $(lib) and $(wildcard $(L))) 
Endef 

The loop: the Class=
$(foreach, L, $(loop) and $(eval $(call VAR, $(L)))) 

PHONY: all 
All: 
@ echo Makefile "begin" 
@ echo "source:" $(source) 
@ echo "lib:" $(lib) 
@ echo "SRC:" $(SRC) 
@ echo "Makefile end 
"

A relatively simple Makefile, I/cc/test/CPP/SRC directory have NgClass. Cc HoClass. Cc F1Class. Cc three files
I expect the SRC can then get this three filename, bring the directory

But now I'm the execution of the fruit like this:
The Makefile begin
Source: No Ng Ho F1
Lib/cc/test/CPP/SRC/NgClass. Cc/cc/test/CPP/SRC/HoClass. Cc/cc/test/CPP/SRC/F1Class. Cc/cc/test/CPP/SRC/NoClass. Cc
SRC:
The Makefile end

Why is this? O great god answer
