我继承了一个使用boost mpi for python的大型python系统。 所以我从源代码构建了boost 1.52，包括mpi和python组件。
我已经从http://mathema.tician.de/software/boostmpi为python 1.38.0.1构建了boost mpi。 我意识到有更新的库（mpi4py），但我继承的软件使用boost mpi。
当我尝试使用它时，我得到......

我该如何解决这个问题？
使用ldd进行测试：

您错误地构建了库。您的boostmpi / _internal.so要么没有链接到某些boost-mpi lib，要么期望与您拥有的版本不同。你可以使用
ldd /projects/nrel/cid/lada.2013/pkgi/lib/python2.7/site-packages/boostmpi-1.38.0.1-py2.7-linux-x86_64.egg/boostmpi/_internal.so
检查正在加载的库，如果有的话。

继承你的问题
boostmpi-1.38.0.1-py2.7-linux-x86_64.egg/boostmpi/_internal.so libboost_python.so.1.52.0 => /projects/nrel/cid/lada.2013/pkgi/lib/libboost_python.so.1.52.0
boostmpi-1.38.0
libboost_python.1.52.0
你必须修复你的路径才能获得两个不同版本的boost，
