尝试构建Boost MPI,但不创建lib文件.这是怎么回事？

Question

我试图用Boost MPI运行一个程序,但问题是我没有.lib.所以我尝试按照http://www.boost.org/doc/libs/1_43_0/doc/html/mpi/getting_started.html#mpi.config上的说明创建一个.

指令说"对于许多使用LAM/MPI,MPICH或OpenMPI的用户来说,配置几乎是自动的",我在C:\中得到了自己的OpenMPI,但我没有做更多的事情.我们需要做任何事情吗？我在程序文件中也得到了自己的MPICH2,并且没有做任何更多的事情.在这一点上,我非常不确定我们必须做什么.

除此之外,该指令的另一个声明:"如果您的主目录中还没有文件user-config.jam,请在那里复制tools/build/v2/user-config.jam." 好吧,我只是按照它说的做.我在C:\ boost_1_43_0>中获得了"user-config.jam"以及"使用mpi;" 进入文件.

接下来,这就是我所做的:bjam --with-mpi

C:\boost_1_43_0>bjam --with-mpi

...found 1 target...


The Boost C++ Libraries were successfully built!

The following directory should be added to compiler include paths:

    C:\boost_1_43_0

The following directory should be added to linker library paths:

    C:\boost_1_43_0\stage\lib


C:\boost_1_43_0>

我看到C:\ boost_1_43_0\stage\lib中有很多库,但我看不到libboost_mpi-vc100-mt-1_43.lib或libboost_mpi-vc100-mt-gd-1_43.lib的痕迹.这些是在mpi应用程序中链接所需的库.

没有构建库时可能出现什么问题？

我怀疑它只是没有读取你的user-config.jam ...当构建引用并搜索user-config.jam时,它会在%HOME%位置中这样做.不在Boost源的根目录中,也不在当前目录中.但是你可以使用一个特定的user-config.jam文件,并带有一个选项:bjam --user-config=user-config.jam ....哪个只会在当前目录中查找.或者您也可以指定文件的完整路径.您应该阅读mpi.jam工具文件(mpi.jam)中的注释,因为它解释了它将自动设置mpi工具的条件.特别是关于mpic++你的道路的说明.
