DevCPP制作文件錯誤

Question

我正在嘗試編譯代碼，但出現此錯誤，我不明白，我的代碼有什么問題

# Project: Project1
# Makefile created by Dev-C++ 5.6.0

CPP      = g++.exe
CC       = gcc.exe
WINDRES  = windres.exe
OBJ      = main.o
LINKOBJ  = main.o
LIBS     = -L"C:/Program Files (x86)/Dev-Cpp/MinGW64/lib" -L"C:/Program Files (x86)/Dev-Cpp/MinGW64/x86_64-w64-mingw32/lib" -static-libgcc
INCS     = -I"C:/Program Files (x86)/Dev-Cpp/MinGW64/include" -I"C:/Program Files (x86)/Dev-Cpp/MinGW64/x86_64-w64-mingw32/include" -I"C:/Program Files (x86)/Dev-Cpp/MinGW64/lib/gcc/x86_64-w64-mingw32/4.8.1/include"
CXXINCS  = -I"C:/Program Files (x86)/Dev-Cpp/MinGW64/include" -I"C:/Program Files (x86)/Dev-Cpp/MinGW64/x86_64-w64-mingw32/include" -I"C:/Program Files (x86)/Dev-Cpp/MinGW64/lib/gcc/x86_64-w64-mingw32/4.8.1/include" -I"C:/Program Files (x86)/Dev-Cpp/MinGW64/lib/gcc/x86_64-w64-mingw32/4.8.1/include/c++"
BIN      = Project1.exe
CXXFLAGS = $(CXXINCS) 
CFLAGS   = $(INCS) 
RM       = rm -f

.PHONY: all all-before all-after clean clean-custom

all: all-before $(BIN) all-after

clean: clean-custom
    ${RM} $(OBJ) $(BIN)

$(BIN): $(OBJ)
    $(CPP) $(LINKOBJ) -o $(BIN) $(LIBS)

main.o: main.cpp
    $(CPP) -c main.cpp -o main.o $(CXXFLAGS)

Answer 1

由於在Stackoverflow上發布時可能會重新格式化文本，因此無法確定，但我的印象是在代碼的最后幾行：

clean: clean-custom
        ${RM} $(OBJ) $(BIN)

$(BIN): $(OBJ)
        $(CPP) $(LINKOBJ) -o $(BIN) $(LIBS)

main.o: main.cpp
        $(CPP) -c main.cpp -o main.o $(CXXFLAGS)

您應該在以$開頭的行之前有一個制表符（並且只有一個！）。 沒有空格或其他任何內容。
