我试图在Dev-C++中编译一个简单的c文件，它在第25行显示了一个错误C:UsersvarunDesktopcprogMakefile.win recipe for target 'Project1.exe' failed.

Makefile.win

# Project: Project1
# Makefile created by Dev-C++ 5.6.2
CPP      = g++.exe
CC       = gcc.exe
WINDRES  = windres.exe
OBJ      = main.o Untitled2.o
LINKOBJ  = main.o Untitled2.o

BIN      = Project1.exe
CXXFLAGS = $(CXXINCS) 
CFLAGS   = $(INCS) 
RM       = rm.exe -f
.PHONY: all all-before all-after clean clean-custom

main.o: main.c
    $(CC) -c main.c -o main.o $(CFLAGS)
Untitled2.o: Untitled2.c
    $(CC) -c Untitled2.c -o Untitled2.o $(CFLAGS)

错误

C:UsersvarunDesktopcprogUntitled2.o    Untitled2.c:(.text+0x0): multiple definition of `main'
C:UsersvarunDesktopcprogmain.o main.c:(.text+0x0): first defined here
C:UsersvarunDesktopcprogcollect2.exe   [Error] ld returned 1 exit status
25      C:UsersvarunDesktopcprogMakefile.win   recipe for target 'Project1.exe' failed

输出的重要位是：

C:UsersvarunDesktopcprogUntitled2.o    Untitled2.c:(.text+0x0): multiple definition of `main'

它告诉你，你有两个函数main的定义。在一个可执行文件中只需要一个这样的定义。错误的下一行告诉您，定义是：

C:UsersvarunDesktopcprogmain.o main.c:(.text+0x0): first defined here

所以在Untitled2.c中定义了函数main，在main.c中定义了另一个函数main。删除其中一个。从名称上看，main.c可能完全没有必要，但如果没有看到文件，我就无法判断。
