C++ 使用boost:：interprocess编译链接器时出错

我已经编写了一个小程序，将boost:：interprocess:：container字符串写入共享内存，并从中读取另一个

我收到以下链接器错误：

我还尝试与以下内容联系：

g++ -c SharedMemTest.cpp
g++ -L /usr/lib/x86_64-linux-gnu/librt.a SharedMemTest.o -o SharedMemTest

---

但这些命令都不起作用。有人能告诉我如何编译这个简单的例子吗？

-L的参数应该是一个目录，但是你在它后面放了一个库文件名。你可能是指

-l rt

。其他人已经建议使用

-l pthread

，您也可以使用

-pthread

链接到pthreads库。

g++-lpthread-lrt-SharedMemTest.cpp

（包括pthread和rt库）。你至少试过谷歌搜索吗？@Yossarian，很明显，因为你的推荐也不起作用。如果谷歌对一切都有答案，我们就不需要了，是吗？@czchlong:他的建议应该有效，但是试试

g++SharedMemTest.cpp-lpthread-lrt

（订单问题）。@ildjarn，非常感谢。秩序确实重要。谢谢可能重复的
