– To configure the program, edit the file “jsconfig.h”. Since this is a general configuration file, not all settings may apply to this package. If in doubt, use grep or anything else to find out if a specific configuration symbol is used somewhere.

– No default optimization option is used in the Makefile since this is compiler dependent. One has to find out what option produces the best result on the platform. Check the manual of your C-compiler for more information. The variable COPTIMIZE is reserved for optimization. For some systems I have experience with optimization options are given at the beginning of the Makefile, uncomment them for your system.

– Some programs use numerical libraries for matrix diagonalization and to speed up FFT (set in “jsconfig.h” as a “CONFIG_LIB_…” symbol). In linking the variable NUMLIB is used for that purpose. The values for various systems I use are given at the beginning of the Makefile, uncomment the one for your system. Note that these libraries are FORTRAN libraries and thus part of the NUMLIB setting is only needed for FORTRAN linkage.

– The file “ErrCodes.c” contains an array of all error messages that will be produced by the library routines, similar to the ANSI “strerror”-function. The library can be configured to load error messages only on demand from the file “Error.txt” which contains the error messages as ASCII text. This saves space in the executables. For that the file “Error.txt” has to be installed globally accessible in a fixed place and the path name of the file has to be defined like

#define CONFIG_ERRMSGFILE “/this/is/the/path/name”

while compiling the package (see “jsconfig.h”).
