A Fortran 77 compiler is required. As supplied +it uses the g77 Fortran compiler, but this can be changed by editing the ast_tester +script. + +To perform a test: + +- build AST + +- define the environment variables AST and STARLINK so that $AST/lib contains + the AST libraries to be tested, and $STARLINK/lib contains the the USSC libraries. + +- If required, edit the ast_tester script to modify the fortran compiler and/or options. + +- execute the ast_tester script. + + +The script generates various output files which are compared with existing files +which are presumed to represent correct behaviour of the AST library. Any differences +are reported by the script. + +The script also generates various postscript files representing "critically difficult" plots. +A file "*-new.ps" is created for each file "*.head" in the directory. The directory also +contains files "*.ps" which represent the expected appearance of the plots. By default, the +new plots are displayed using ghostview. This can be disabled by specifying the "-nd" option +on the ast_tester command line. + + + + + + |
