我想使用gcc 4.5.2在Ubuntu 11.04上构建所有Boost库。所以我去下载tar.bz2文件。我扩展了它。我运行bootstrap.sh并注意到它抱怨unicode，所以我安装了：
sudo apt-get install libicu-dev
现在看起来很高兴用unicode构建。麻烦的是我想要链接OpenMPI。哦，哦。所以我将using mpi ;添加到./tools/build/v2/user-config.jam并运行我的构建命令：
./bjam --layout=versioned --build-type=complete
并且提示打印错误（我缩写了大段落）：
error: Duplicate name of actual target: <pstage/lib>mpi.so
error: previous virtual target { common%common.copy-mpi.so.PYTHON_EXTENSION {
...然后几页......
error: created from ./stage-proper
error: another virtual target { common%common.copy-mpi.so.PYTHON_EXTENSION {
...然后再多几页......

似乎是bug可追溯到Boost 1.40？但我知道其他人已经开始工作了。有没有人知道让Boost 1.46.1与openmpi玩得很好所需的伏都教？
注意：我一直在谷歌搜索，这似乎不是Ubuntu特定的问题 - 它出现在gentoo和其他地方。但我没有找到任何具体的解决方案，除了 build without mpi ... 我不能。
我很乐意发布整个日志，包版本等。

从其他论坛，我发现在/ tools / build / CMake / externals中，应该有一个MPI.cmake文件。 添加以下行应该允许您使用OpenMPI构建Boost：
set(MPI_INCLUDE_PATH /usr/include/openmpi-x86_64)
set(MPI_COMPILE_FLAGS -I/usr/include/openmpi-x86_64)
set(MPI_LINK_FLAGS -L/usr/lib64/openmpi/lib -L/usr/lib64/openmpi/lib/openmpi
-lmpi_cxx -lmpi)
set(MPI_LIBRARIES /usr/lib64/openmpi/lib/libmpi.so
/usr/lib64/openmpi/lib/libmpi_cxx.so)
set(MPI_FOUND 1)
