=============================================================

Boost 1.55

yum install libicu-devel python python-devel bzip2-devel zlib-devel

PS if you want to install boost_mpi, install openmpi, and be sure the link is ok (mpic++, mpirun, be sure that EXPORT PATH is ok)

yum install openmpi-devel

wget -c 'http://sourceforge.net/projects/boost/files/boost/1.55.0/boost_1_55_0.tar.bz2/download'

tar xf download

cd boost_1_55_0

./bootstrap.sh

echo "using mpi ;" >> tools/build/v2/user-config.jam

vim project-config.jam （change install path）

Boost Libraries enabling the C++11 compiler support.

(.so)

./b2 toolset=gcc cxxflags=-std=c++0x -j 4

./b2 toolset=gcc cxxflags=-std=c++0x install -j 4

if you want to using static library (.a)

./b2 toolset=gcc cxxflags=-std=c++0x link=static -j 4

./b2 toolset=gcc cxxflags=-std=c++0x link=static install -j 4

ps for refined library 

./b2 —reconfigure
