Configuration examples

When configuring your build, bear in mind the limitation (mentioned in § 1) that we require a reasonably standard compliant C++ compiler. Unfortunately for many Red Hat Linux users, Red Hat continues to ship their system with a non-release versions of g++, which often fail on some of the more challenging C++ constructs found in Spheral++ and the included Boost library. If you are using such non-standard compilers it will likely be necessary to obtain a modern version of gcc. In §2.5.2 below we show an example building on such a Red Hat based system, overriding the compiler to use the 3.4.3 series of Gnu compilers. The following are some generic configuration examples:

• To build a serial debugable version, assuming the default compiler choices are OK:

  ./configure --with-compilers=gnu --without-mpi
  

• To build a similar serial optimized code

  ./configure --with-compilers=gnu --without-mpi --with-opt=2 --with-dbc=none
  

• To build an optimized parallel executable, manually setting the compiler choices:

  ./configure --with-opt=2 --with-dbc=none \
              --with-CC=gcc --with-CXX=g++ \
              --with-MPICC=mpicc --with-MPICXX=mpiCC
  

In the sections below we show examples of configurations on several platforms in use at LLNL.
