Makefile issues: g++: fatal error: no input files
提问by NewGradDev
What I've already done:
我已经做了什么：
I've looked through other StackOverflow threads with similar issues, but none of them seem to apply to my specific case. I've also double checked to makes sure that the correct files are in the correct locations (folders) and that everything is named properly as well.
我已经查看了其他具有类似问题的 StackOverflow 线程，但它们似乎都不适用于我的特定情况。我还仔细检查以确保正确的文件位于正确的位置（文件夹），并且所有内容的命名也正确。
This is the error I'm receiving:
这是我收到的错误：
[[email protected]]$ make
g++ -Wall -O2 -ansi -pedantic -o dog.cpp
g++: fatal error: no input files
compilation terminated.
make: *** [mscp.o] Error 4
Here's the makefile in question:
这是有问题的makefile：
CC = g++
CFLAGS = -Wall -O2 -ansi -pedantic -Werror
TARGETS = dog dog.o collar.o
dog: dog.o collar.o
$(CC) $(CFLAGS) -o dog collar.o dog.o
dog.o: dog.cpp collar.h
$(CC) $(CFLAGS) -o dog.cpp
collar.o: collar.cpp collar.h
$(CC) $(CFLAGS) -o collar.cpp
clean:
-rm -f ${TARGETS}
Here are the files (they're all in the same directory) that are being referenced by the makefile:
以下是 makefile 引用的文件（它们都在同一目录中）：
-collar.cpp
-collar.h
-makefile
-dog.cpp
What am I doing wrong?
我究竟做错了什么？

Try doing
尝试做
$(CC) $(CFLAGS) - c collar.cpp -o compiledfilename
Compiledfilename is the name of the binary file.
Compiledfilename 是二进制文件的名称。

dog.o: dog.cpp collar.h
$(CC) $(CFLAGS) -o dog.cpp
collar.o: collar.cpp collar.h
$(CC) $(CFLAGS) -o collar.cpp

I know it is too late to answer. But this might help some else. I had the same issue. And I fixed it by replacing .hfile with .hppfile. It worked :)
我知道现在回答已经太晚了。但这可能对其他人有所帮助。我遇到过同样的问题。我通过用.hpp文件替换.h文件来修复它。有效 ：）
