c++ - 涉及 `crti.o` 和 `crt1.o` 的奇怪链接器错误

Question

我在这里阅读了类似问题的“解决方案”:

• Link 1
• Link 2
• Link 3

我已经尝试重新安装 libc-dev、binutils、build-install、gcc-multilib 和链接解决方案 sudo ln -s/usr/lib/x86_64-linux-gnu/usr/lib64。

命令 find/usr/-name crti* 给出:

/usr/libx32/crti.o
/usr/lib/x86_64-linux-gnu/crti.o
/usr/lib/debug/usr/lib/x86_64-linux-gnu/crti.o
/usr/lib32/crti.o

我得到的错误是:

我使用的 makefile 是:

PROBLEM = 108
CC=g++
CFLAGS=-Wall -std=c++11  -c
LDFLAGS=-Wall -std=c++11
SOURCES=$(PROBLEM).cpp
OBJECTS=$(SOURCES:.cpp=.o)
EXECUTABLE=prob-$(PROBLEM)

all: $(SOURCES) $(EXECUTABLE)

$(EXECUTABLE): $(OBJECTS)
    $(CC) $(OBJECTS) -o $@ $(LDFLAGS)

.cpp.o:
    $(CC) $(CFLAGS) $< -o $@

clean:
    rm -rf *.o

run: 
    ./$(EXECUTABLE)

构建目录的 ls -l 给出:

-rw-r--r-- 1 nictrasavios nictrasavios  1077 Dec 28 05:32 108.cpp
-rwxr-xr-x 1 nictrasavios nictrasavios 30534 Dec 28 05:32 108.o

-rw-r--r-- 1 nictrasavios nictrasavios   325 Dec 28 05:57 makefile

问题是什么？

Answer 1

所以，显然 某事 我确实工作了......因为在运行 make clean 之后......

嗯，

g++ -Wall -std=c++11 -c 108.cpp -o 108.o
g++ 108.o -o prob-108 -Wall -std=c++11

构建良好。修复链接错误后我忘记清理了……不知何故。

对不起，我想这会成为一个未解之谜。

我的直觉是 export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:$LIBRARY_PATH 有效。
