Question

我尝试了-L命令直接更改链接器搜索，甚至尝试了-Wl，-rpath，/ mydir和-Wl，-rpath-link，/ mydir，但是g ++似乎仍在搜索/ usr / bin / ld。我在这里做错了什么？抱歉，如果我在没有IDE的情况下刚接触新东西，那是公然的错误。

我当前正在使用的Makefile。

    #Makefile for compiling library.
CC       = g++
CURNTDIR = $(shell pwd)
IFLAG    = -I$(CURNTDIR)/include
LFLAG    = -L$(CURNTDIR)/lib
LIBS     = -llibSDLmain -llibSDL2
CXXFLAGS = -Wl,-rpath,$(CURNTDIR)/lib -Wl,-rpath-link,$(CURNTDIR)/lib
objs     = SpiceMain.o SystemHandler.o

SpiceMain: $(objs)
    $(CC) -o $@ $(CXXFLAGS) $(IFLAG) $(LFLAG) $(objs) $(LIBS)

SpiceMain.o: SpiceMain.cpp
    $(CC) -c $(CXXFLAGS) $(IFLAG) $(LFLAG) $? $(LIBS)

SystemHandler.o: SystemHandler.cpp
    $(CC) -c $(CXXFLAGS) $(IFLAG) $(LFLAG) $? $(LIBS)

clean:
    rm $(objs)
    rm SpiceMain

返回的终端错误。

g++ -o SpiceMain -Wl,-rpath,/home/harry/Desktop/programs/spiceengine/lib -Wl,-rpath-link,/home/harry/Desktop/programs/spiceengine/lib -I/home/harry/Desktop/programs/spiceengine/include -L/home/harry/Desktop/programs/spiceengine/lib SpiceMain.o SystemHandler.o -llibSDLmain -llibSDL2
/usr/bin/ld: cannot find -llibSDLmain
/usr/bin/ld: cannot find -llibSDL2
collect2: error: ld returned 1 exit status
make: *** [Makefile:11: SpiceMain] Error 1

在此先感谢任何可以提供帮助的人。

我认为您需要省略“ lib *”前缀（和* .so后缀）：

-L/my/library/path -lSDLmain -lSDL2

为什么g ++无法正确链接到指定的-L路径？
