Makefile给我一个错误-没有这样的文件或目录 [英] Makefile is giving me an error - No such file or directory

问题描述

我有一个非常简单的makefile.我在此makefile中要做的只是编译我的文件并为测试创建可执行文件.我有以下文件:

I have a very simple makefile. All I want to do in this makefile is compile my files and create an executable for my test. I have the following files:

• Test.cpp-主要功能
• BaseClass.cpp
• BaseClass.h-基类的头文件
• DerivedClass.cpp-继承基类
• DerivedClass.h-派生类的头文件

这是我拥有的makefile:

Here is the makefile I have:

all: Test

Test: BaseClass.o DerivedClass.o Test.o
    g++ -o BaseClass.o DerivedClass.o Test.o Test

Test.o: Test.cpp BaseClass.h DerivedClass.h
    g++ -c Test.cpp

Package.o: BaseClass.cpp BaseClass.h
    g++ -c BaseClass.cpp

DerivedClass.o: DerivedClass.cpp DerivedClass.h
    g++ -c DerivedClass.cpp

clean:
    rm -rf *.o

我以前从未创建过5个文件的makefile.我可以很容易地用3创建一个，但是我不知道这是怎么回事.我收到的错误是:

I've never created a makefile for 5 files before. I can create one with 3 pretty easily, but I don't know what's wrong. The error I'm getting is:

测试:没有太多文件或目录

谢谢，乔！就是这样我的愚蠢的监督.

Thanks, Joe! That was it. Pretty silly oversight of mine.

推荐答案

Test应该是-o的参数:

Test: BaseClass.o DerivedClass.o Test.o
    g++ -o Test BaseClass.o DerivedClass.o Test.o

注意，我将Test从行尾移到了-o之后.

Notice I moved Test from the end of the line to immediately after -o.
