Selecting the compiler(s)

Spheral++ depends on several compilers for different components, so we have tried to simplify the compiler selection process through the use of the

• --with-compilers=<gnu,intel,vacpp,emsolve>

configure option. Currently the only valid options are gnu, intel, vacpp, or emsolve - the default is gnu. The intel option selects the icc compiler suite, only appropriate on intel environments where this compiler has been installed. Similarly vacpp runs the xlC compile suite on IBM AIX systems. At the time of this writing, however, xlC does not correctly build the Boost third party library set (§A.1.2) , so this option cannot be used. The emsolve compiler suite is a very specialized option that will probably not be of general use.

If the set of compilers selected by one of the above options is not quite right for a particular installation, it is also possible to specify the individual compiler choices via the following set of configure flags.

• --with-CC=<compiler>: Select the serial C compiler.
• --with-CXX=<compiler>: Select the serial C++ compiler.
• --with-MPICC=<compiler>: Select the MPI CC compiler, only necessary if you're building the parallel version of Spheral++.
• --with-MPICXX=<compiler>: Select the MPI C++ compiler, also only necessary if you're building the parallel code.
• --with-python-CC=<compiler>: A.1.1 Manually select the C compiler to build python with. Defaults to the C compiler selected by --with-CC.
• --with-python-CXX=<compiler>: A.1.1 Manually select the C++ compiler to build python with. Defaults to the C++ compiler selected by --with-CXX.
• --with-GCCXML-CC=<compiler>: A.1.7a Manually select the C compiler to build GCC_XML with. Defaults to the C compiler selected by --with-CC.
• --with-cmake-CC=<compiler>: A.1.7b Manually select the C compiler to build cmake with. Defaults to the C compiler selected by --with-CC (except on AIX, where xlc is the default.)
• --with-cmake-CXX=<compiler>: A.1.7b Manually select the C++ compiler to build cmake with. Defaults to the C++ compiler selected by --with-CXX (again except on AIX, where xlC is the default.)
