BUFRDC library have been tested for different machine architectures that exist in ECMWF:
- Decalpha - Compaq Fortran 90, C++ compilers
- Hppa - HP Fortran and C compilers
- Linux - The Portland Group compilers pgf90 and pgcc, Gnu project gcc, g77 compilers
- Rs6000 - XL Fortran for AIX- C for AIX Compiler, Version 5
- Sgimips - MIPSpro F77 compiler- MIPS C compiler
- Sun4 - Forte Developer 7 Fortran 95 compiler SunOS/BSD Compatibility Package C compiler
It is possible to use other options for the compilation of source code versions than those which are offered. For example: modifying the configuration files; changing the level of optimisation; etc. The make utility can be used repeatedly. It will only cause the re-compilation of routines which have been modified since the previous make.
You can install BUFRDC library on Windows only if you have Cygwin linux-like environment for Windows and Gnu compilers.
Installation is possible on Mac OS 10.1 onward using Gnu compilers.
The number of bits in the representation of real numbers can be chosen between 32bits and 64bits for all compilers apart from the Gnu compilers.
The library is static and its name follows the normal UNIX convention (it starts with lib and ends in .a), so the library can be specified in the compile/link command using the
standard ld convention, for example:
f77 -o program program.f -lbufr
Packages contains example for the BUFR decoding and number of useful tools for conversion from BUFR to CREX and vise versa.
IF build_library SCRIPT IS USED TO BUILD THE LIBRARY AND install SCRIPT TO INSTALL LIBRARY AND TABLES, IT IS NOT NECESSARY TO SET ENVIRONMENTAL VARIABLE BELOW THAT POINT TO THE TABLES!
After succesfully instalation the location of BUFR tables could be specified by putting the specification of the environment variables in your startup files(.profile, ...) to ensure you have access to the tables upon future logins.
Thus:
BUFR_TABLES = "chosen directory"/bufrtables/ export BUFR_TABLES
setenv BUFR_TABLES "chosen directory"/bufrtables/
Please note:
All software items above are available in the format "* .tar.gz" ie gzipped and tarred source for use with Unix or Linux based systems.
