使用boost :: interprocess编译链接器错误

我编写了一个小程序，它将boost :: interprocess :: container字符串写入共享内存，另一个程序将其读取。使用boost :: interprocess编译链接器错误

我收到如下链接错误：

我也曾尝试用下面的链接：

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

但是，这些命令都在工作。有人可以告诉我怎样才能得到这个简单的例子来编译？

'g ++ -lpthread -lrt SharedMemTest.cpp'（包括pthread和rt库）。你至少试过Google搜索吗？ – nothrow

@Yossarian，显然，因为你的建议也不起作用。如果谷歌有一切的答案，我们不需要这样做，我们会吗？ – czchlong

@czchlong：他的建议_应该可以工作，但可以尝试'g ++ SharedMemTest.cpp -lpthread -lrt'（命令很重要）。 – ildjarn

-L的参数应该是一个目录，但是你要在它之后放置一个库文件名。你可能意思是-l rt。其他人已经建议-l pthread，您也可以使用-pthread链接到pthreads库。
