Makefile vpath不适用于头文件
我试图在我的Makefile中使用vpath,以避免为每个源文件添加目录名。
I am trying to use vpath in my Makefile to avoid prefixing every source file with directory name. But I can't get it to work properly.
Here's the Makefile:
c $ c> CC = gcc -Wall
vpath%.h包含
vpath%.c src
all:main.c Event.o Macros.h
$(CC)$& Event.o -o test / a.out
Event.o:Event.c Event.h Macros.h
$(CC)-c $& -o $ @
CC=gcc -Wall
vpath %.h include
vpath %.c src
all: main.c Event.o Macros.h
$(CC) $< Event.o -o test/a.out
Event.o: Event.c Event.h Macros.h
$(CC) -c $< -o $@
正确包含src 目录。即event.c文件由gcc找到。但是Event.h和Macros .h都不是。我在gcc中得到一个错误,说在编译Event.c时找不到这两个文件。
The src directory is being included correctly. i.e Event.c file is found by gcc. But both Event.h and Macros .h are not. I get an errors in gcc saying that both files were not found when compiling Event.c.
我试图将C文件中的#include指令更改为一个时间。
I tried changing the #include directive in my C file to each of these at a time.
#include "Event.h" /* doesnt work */
#include <Event.h> /* doesnt work */
#include "../include/Event.h" /* works */

您能帮我解决这个问题吗?我真的想避免在每个源文件之前使用目录名,因为我的实际Makefile比这大。
Can you please help me with this problem ? I really want to avoid using directory names before every source file as my actual Makefile is bigger than this.
$ c> vpath 指令仅控制Make如何查找依赖关系;它不以任何方式影响GCC的工作原理。如果你在其他目录下有头文件,你明确需要告诉GCC -I
:
The vpath
directive only controls how Make finds dependencies; it doesn't affect in any way how GCC works. If you have headers in some other directory, you explicitly need to tell GCC with -I
:
INCLUDE := include
$(CC) -I$(INCLUDE) $c $< -o $@
