########################################################### #ARCH <os> (fortran) compiler with (C) compiler # serial smpar dmpar dm+sm # # (The last four words on the line above indicate what parallel modes are supported for this build. # Presence of serial indicates the code can be built single-threaded and an option will be presented # by the configure script for this. Likewise, presence of smpar indicates shared-memory parallel (OpenMP), # dmpar indicates distributed memory parallel (MPI), and dm+sm indicates both. The comment character # before the first word is not necessary but it makes the choices neater when the configure script # displays them to the user) # # (The settings below should be all that are needed per architecture/installation.

MODULE_SRCH_FLAG = (flag to compiler to tell it where to search for modules -- PGI needs) TRADFLAG = (flag to cpp to tell it to act like it did before script kiddies got hold of it) CPP = (cpp command) AR = (ar command) ARFLAGS = (flags to ar command, want ru capability) M4 = (m4 command) RANLIB = (ranlib command if needed) CC_TOOLS = (the cc command that should be used for compiling in the tools directory.
