打扰了, makefile问题, 这样的情况该怎么写

smfyg

论坛的一些精华确实经典, 不过对我来说就大材小用了. 我也试图取理解不过太紧了理解不了, 还请帮忙.
现在有三个目录(都在mydir下):
a(1.cpp和1.h文件),b(2.cpp和2.h文件),c(3.cpp和3.h文件)
每个目录下都有自己的头文件和cpp文件main函数在a目录的1文件.

我应该把makefile写到mydir下吗?
我这样下对不:
#INDIR=-I/usr/include/ -I./

A_DIR=./a
B_DIR=./b
C_DIR=./c

des:1.o 2.o 3.o            
        g++ -o $@ %^
               
1.o(A_DIR)/1.cpp $(A_DIR)/1.h
        g++ -c -o $@ $(A_DIR)/1.cpp
       
2o(B_DIR)/2.cpp $(B_DIR)/2.h
        g++ -c -o $@ $(A_DIR)/2.cpp
       
3.o(C_DIR)/3.cpp $(C_DIR)/3.h
        g++ -c -o $@ $(A_DIR)/3.cpp
       

或者应该把makefile下到a下面, 还是没有关系, 不过makefile文件这样写有什么问题?

大概看了一下 整体没什么问题

你贴make的出错信息阿

smfyg

实际的makefile:
MAIN_DIR=./CompleteFile/
DB_DIR=./kiwiDB/
API_DIR=./com/

linkindextable(MAIN_DIR)/CompleteFile.o $(MAIN_DIR)/BackLead.o \
               $(DB_DIR)/DataBlockManageCls.o $(DB_DIR)/AllDataManageCls.o \
               $(DB_DIR)/ParsedRegionDataBlockCls.o $(API_DIR)/NAS_com_API.o               
        g++ -o $@ %^
               
CompleteFile.o(MAIN_DIR)/CompleteFile.cpp $(MAIN_DIR)/CompleteFile.h
        g++ -c -o $@ $(MAIN_DIR)/CompleteFile.cpp
       
BackLead.o(MAIN_DIR)/BackLead.cpp $(MAIN_DIR)/BackLead.h
        g++ -c -o $@ $(MAIN_DIR)/BackLead.cpp
       
DataBlockManageCls.o(DB_DIR)/DataBlockManageCls.cpp $(DB_DIR)/DataBlockManageCls.h
        g++ -c -o $@ $(DB_DIR)/DataBlockManageCls.cpp
       
AllDataManageCls.o(DB_DIR)/AllDataManageCls.cpp $(DB_DIR)/AllDataManageCls.h $(DB_DIR)/pubstruct.h
        g++ -c -o $@ $(DB_DIR)/AllDataManageCls.cpp
       
ParsedRegionDataBlockCls.o(DB_DIR)/ParsedRegionDataBlockCls.cpp $(DB_DIR)/ParsedRegionDataBlockCls.h
        g++ -c -o $@ $(DB_DIR)/ParsedRegionDataBlockCls.cpp
       
NAS_com_API.o(API_DIR)/NAS_com_API.cpp $(API_DIR)/NAS_com_API.h
        g++ -c -o $@ $(API_DIR)/NAS_com_API.cpp

MAIN_DIR = CompleteFile

smfyg

试了试结果还是一样
是不认那三个变量?

windflowers1976

我用了你一样的语法,没有问题.

我是在惠普机器上调的
不会和机器配置有关吧

刚好有环境,我在SCO506 REDHAT9 HP10 下均没有问题
Makefile 里有没有乱字符?
====================================
Makefile
dir=./
a(dir)/a.c
        echo "ff"
~

smfyg

没有乱字符
我是通过网络映射驱动器用ultraedit编辑的,
不过通过telnet我用vi看了
确实没有乱字符, 回车换行也没问题

把MAIN_DIR=./CompleteFile/
DB_DIR=./kiwiDB/
API_DIR=./com/

改成
MAIN_DIR=./CompleteFile
DB_DIR=./kiwiDB
API_DIR=./com

试试
