Makefile找不到libs

Question

我正在尝试为我的项目编写Makefile.这是文件结构:

Makefile文件:

CXXFLAGS = -ISDL2/include -std=c++11
LXXFLAGS = -lSDL2/lib/x86 -lSDL2main -lSDL2 -lSDL2_image

main.exe: main.o BoardField.o ChessPiece.o Game.o
    g++ main.o BoardField.o ChessPiece.o Game.o -o main.exe $(LXXFLAGS) -std=c++11

main.o: main.cpp 
    g++ main.cpp -c $(CXXFLAGS)

BoardField.o: BoardField.cpp 
    g++ BoardField.cpp -c $(CXXFLAGS) 

ChessPiece.o: ChessPiece.cpp 
    g++ ChessPiece.cpp -c $(CXXFLAGS) 

Game.o: Game.cpp 
    g++ Game.cpp -c $(CXXFLAGS)  

我收到这些错误:

g ++ main.o BoardField.o ChessPiece.o Game.o -o main.exe -lSDL2/lib/x86 -lSDL2main -lSDL2 -lSDL2_image -std = c ++ 11 c:/ mingw/bin /../ lib/gcc /mingw32/6.3.0/../../../../mingw32/bin/ld.exe:找不到-lSDL2/lib/x86 c:/ mingw/bin /../ lib/gcc/mingw32 /6.3.0/../../../../mingw32/bin/ld.exe:找不到-lSDL2main c:/ mingw/bin /../ lib/gcc/mingw32/6.3.0 /. ./../../../mingw32/bin/ld.exe:找不到-lSDL2 c:/ mingw/bin /../ lib/gcc/mingw32/6.3.0 /../../. ./../mingw32/bin/ld.exe:找不到-lSDL2_image

问题出在哪儿？

-lSDL2/lib/x86是不正确的.您使用小写-l选项,用于添加要链接的库,而不是搜索库的路径.

要添加路径,请使用大写-L选项:-LSDL2/lib/x86
