GRIB_API (1.9.9 or higher)
see the Installation FAQ for details of building GRIB_API for Metview, as this contains some important information
version 392 or higher:
compiled with double floating point precision (answer “y” to “Do you want 64-bit reals? [y,n]”)
must be built with GRIB_API support
64-bit versions should be built with -fPIC compilation flag
- Remember to set the ARCH environment variable before building Emoslib, e.g.
export ARCH=linux.
- version 400 or above:
- compiled with double floating point precision (this is the default)
- compiled with double floating point precision (this is the default)
| Info |
|---|
The latest versions of EmosLib depend on GRIB_API, therefore GRIB_API must be installed before EmosLib. |
...
Any C++ Compiler which supports features required for the ANSI C++ standard from 1998 (STL, namespaces, templates) should work with Metview. At ECMWF we tested GCC’s g++ 4.1, 4.3 and 4.5 successfully. A Fortran compiler is required to build some of Metview's modules. It will also be required to build EmosLib, for which Cray pointer support is required. At ECMWF the Portland Pgf90 compiler 710.2 8 and GFortran 4.5 and newer were tested successfully on Linux platforms.

so make sure this will not clash with an existing installation. See Compilation and installation on page 6 for details of flags the table of CMake options for the flag which will allow you to change this.
