The SLHA library provides simple routines to read and write files in SLHA format. It performs input and output tasks only and does not modify the numbers, which means there is no routine to compute, say, a particular quantity at a new scale. The library is written in native Fortran 77 and data are kept in a single double complex array and accessed through preprocessor variables.

./configure maketo build the library libSLHA.a. There are two simple demonstration programs in the demo subdirectory.
Compiling a program that uses the SLHA library is in principle equally straightforward. The only tricky thing is that one has to relax Fortran's 72-column limit. This is because even lines perfectly within the 72-column range may become longer after the preprocessor's substitutions. While essentially every Fortran compiler offers such an option, the name is quite different. A glance at the man page should suffice to find out. Here are a few common choices:
|pgf77, pgf90, pghpf||Linux x86, MacOS||-Mextend|
|ifort||Linux x86, MacOS||-extend_source|
|f77, f90||Tru64 Alpha||-extend_source|
To compile and link your program, add this option and -Ipath/include -Lpath/lib -lSLHA to the compiler command line, where path is the location of the SLHA library, e.g.
gfortran -ffixed-line-length-none -I$HOME/SLHALib-m.n/include myprogram.F -L$HOME/SLHALib-m.n/lib -lSLHA
It is also possible to use the SLHALib in C and C++. In this case one needs to include the header file CSLHA.h in the program text. Compilation should be done using the fcc script, i.e. replace the invocation of the C compiler with fcc, as in
fcc -I$HOME/SLHALib-m.n/include myprogram.c -L$HOME/SLHALib-m.n/lib -lSLHAThe fcc script is installed together with the library and automatically adds the necessary libraries for linking with Fortran code.
