Thanks Dave. I have some problem: ./configure --prefix=/usr/local/src/boost.hg/stage --with-icu Building Boost.Jam with toolset gcc... tools/jam/src/bin.linux/bjam Detecting Python version... 2.4 Detecting Python root... /usr Unicode/ICU support for Boost.Regex?... yes. Generating Makefile... [nbecker@nbecker3 boost.hg]$ make ./tools/jam/src/bin.linux/bjam -sPYTHON_ROOT=/usr -sPYTHON_VERSION=2.4 -sHAVE_ICU=1 -sTOOLS=gcc warning: Python location is not configured warning: the Boost.Python library won't be built Building Boost.Regex with the optional Unicode/ICU support disabled. Please refer to the Boost.Regex documentation for more information (and if you don't know what ICU is then you probably don't need it). The mpi module has not been initialized; MPI libraries will not be built. hint: add "using mpi ;" to user-config.jam to enable MPI support. make: *** [all] Interrupt
