/lib/i386-linux-gnu/libpthread.so.0: could not read symbols: 无效的操作

[alkq1989]

如题，遇到的问题如下

Building target: PMS8
Invoking: Cygwin C++ Linker
g++  -o "PMS8"  ./src/MyString.o ./src/main.o ./src/utils.o   -lmpi -lmpi_cxx
/usr/bin/ld: ./src/main.o: undefined reference to symbol 'pthread_create@@GLIBC_2.1'
/usr/bin/ld: note: 'pthread_create@@GLIBC_2.1' is defined in DSO /lib/i386-linux-gnu/libpthread.so.0 so try adding it to the linker command line
/lib/i386-linux-gnu/libpthread.so.0: could not read symbols: 无效的操作
collect2: ld returned 1 exit status
make[1]: *** [PMS8] 错误 1
make[1]:正在离开目录 `/home/lin/Documents/PMS8/Debug'
make: *** [all] 错误 2

网上搜了好长时间，具体的还是不知道我的问题在哪里，用的Ubuntu13.04版本， gcc/g++ 4.6.4版本。下载的软件包解压出来就有makefile文件文件内容如下：

有谁能帮忙解决一下吗吗吗吗？？多谢了！！！！

在object.mk 文件中LIBS行加上-lpthread
