Makefile 报错.segmentation fault

hjack

make的时候出错了，coredump了。

>make
g++ -c test_read.cpp
make: *** [test_read.o] 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: *** [test_read] Segmentation fault (core dumped)

gdb去看一看是什么情况。

以下是makefile文件。

OBJS = shm.o sem.o shmQueue.o

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：

编译是链接到这个/lib/tls/libc.so.6？

看下环境变量等设置

hjack

网上查了下,据说是gcc版本问题.........

hjack

今天在另一台server上跑相同的文件,运行十分顺利....[em021] [em021]
