我的makefile文件有问题吗？

我使用 Makefile_st_task 文件作为Makefile文件，其内容：[code]CC=gcc
sources = log.c u_socket.c u_task.c
objects = $(sources:.c=.o)
include_dirs =
CFLAGS = $(include_dirs) -O0 -DU_OS=OS_LINUX -L.

all: task_o u_task

task_o: $(objects)
$(objects): %.o: %.c
$(CC) -c $(CFLAGS) $< -o $@ u_def.h

u_task:$(objects)
$(CC) -g $(CFLAGS) st_task.c $< -o $@ u_def.h

.PHONY : clean
clean :
-rm edit $(objects)[/code]然后在SUSE11.2系统中使用 make all -f Makefile_st_task 编译程序时提示找不到这个 log.o文件
但是使用ls 命令可以看到这个log.o文件已经生成了，是不是我的makefile文件编辑的有问题才导致这个问题呢？

files := $(shell echo src/*.c)
myobj:=$(files:.c=.o)
CXX=mipsel-uclibc-g++

$(myobj):%.o:%.c

@echo [Compile... $@]
$(Q_)$(CXX) -c -o $@ $< $(CFLAGS)

ktv:$(myobj)
@echo [Link... $@]
$(CXX) -o $@ $(filter %.o, $^) $(LDFLAGS)

这是我的，可以make

有通用的makefile..

谢谢分享，不过我还是想问下，您的这个makefile是自己写的还是工具软件生成的？

这里有一个通用的makefile。（从网上看到的。我已经在使用）
可以用作C/C++混合编译。单独编译当然也没问题。
一般只需指定PROGRAM，CFLAGS等即可[code]###############################################################################
#
# Generic Makefile for C/C++ Program
#
# Author: whyglinux (whyglinux AT hotmail DOT com)
# Date: 2006/03/04

# Description:
# The makefile searches in directories for the source files
# with extensions specified in , then compiles the sources
# and finally produces the , the executable file, by linking
# the objectives.

# Usage:
# $ make compile and link the program.
# $ make objs compile only (no linking. Rarely used).
# $ make clean clean the objectives and dependencies.
# $ make cleanall clean the objectives, dependencies and executable.
# $ make rebuild rebuild the program. The same as make clean && make all.
#==============================================================================

## Customizing Section: adjust the following if necessary.
##=============================================================================

# The executable file name.
# It must be specified.
# PROGRAM := a.out # the executable name
PROGRAM :=

# The directories in which source files reside.
# At least one path should be specified.
SRCDIRS := . # current directory
#SRCDIRS :=

# The source file types (headers excluded).
# At least one type should be specified.
# The valid suffixes are among of .c, .C, .cc, .cpp, .CPP, .c++, .cp, or .cxx.
# SRCEXTS := .c # C program
# SRCEXTS := .cpp # C++ program
SRCEXTS := .c .cpp # C/C++ program
#SRCEXTS :=

# The flags used by the cpp (man cpp for more).
#CPPFLAGS := -Wall -Werror # show all warnings and take them as errors
CPPFLAGS := -g

# The compiling flags used only for C.
# If it is a C++ program, no need to set these flags.
# If it is a C and C++ merging program, set these flags for the C parts.
CFLAGS :=
CFLAGS += -g -Wall

# The compiling flags used only for C++.
# If it is a C program, no need to set these flags.
# If it is a C and C++ merging program, set these flags for the C++ parts.
CXXFLAGS :=
CXXFLAGS += -Wall

# The library and the link options ( C and C++ common).
LDFLAGS :=
LDFLAGS +=

## Customizing Section End!!!
##=============================================================================

## Implict Section: change the following only when necessary.
##=============================================================================
# The C program compiler. Uncomment it to specify yours explicitly.
CC = gcc

# The C++ program compiler. Uncomment it to specify yours explicitly.
CXX = g++

# Uncomment the 2 lines to compile C programs as C++ ones.
#CC = $(CXX)
#CFLAGS = $(CXXFLAGS)

# The command used to delete file.
RM = rm -f

## Stable Section: usually no need to be changed. But you can add more.

对于makefile我也是新手，呵呵，勉强的能看懂

格式错误。
第10行最开头没有tab（或者空格等）！
$为第一个字符。
缩进导致make把那一行作为命令了，但是log.o不是命令。
alick 发表于 2010-7-4 10:54

现在使用[code]CC=gcc
sources=log.c u_socket.c u_task.c
objects=log.o u_socket.o u_task.o
include_dirs=
CFLAGS=$(include_dirs) -O0 -DU_OS=OS_LINUX

all: $(objects) u_task

log.o: log.c
$(CC) -c $(CFLAGS) $< -o $@

u_socket.o: u_socket.c
$(CC) -c $(CFLAGS) $< -o $@

u_task.o: u_task.c
$(CC) -c $(CFLAGS) $< -o $@

u_task: log.o u_socket.o u_task.o
$(CC) -g $(CFLAGS) st_task.c log.c u_socket.c u_task.c -lpthread -o $@

.PHONY : clean
clean :
rm -rf $(objects)[/code]能够对这个工程进行编译了，但是感觉这个makefile文件太不好看了，老大们帮忙改改呀
vfdff 于 2010-07-04 19:03:56发表:

gcc -c -O0 -DU_OS=OS_LINUX -L. u_socket.c u_def.h -o u_socket.o
好像这个命令就不行
提示 gcc: cannot specify -o with -c or -S with multiple files

貌似提示没说文件找不到啊，说的是命令找不到

2# alick

按您的方法调整了，还是提示一个错误,这个又是为什么？
