Makefile 报错.segmentation fault
make的时候出错了，coredump了。>make
g++ -c test_read.cpp
make: *** Segmentation fault (core dumped)
不管，再make一次。还是报错，但这次是另一个命令报的错。
>make
g++ -c test_read.cpp
g++ -c shmQueue.cpp
g++ -c shm.cpp
g++ -c sem.cpp
g++ -g -o test_read test_read.o shm.o sem.o shmQueue.o
make: *** Segmentation fault (core dumped)
gdb去看一看是什么情况。

使用g++直接编译是没有报错的哦。
使用make就是第一次报错后，第二次再make时，原来报错的命令不报了。变成另一条命令报错了。
以下是g++版本信息：
>g++ -v

编译是链接到这个/lib/tls/libc.so.6？
看下环境变量等设置 网上查了下,据说是gcc版本问题......... 今天在另一台server上跑相同的文件,运行十分顺利....
