Having said that, you could manage with only a few of the -many files in the AST distribution. I've played about with this a bit -today, and the following seems to produce a minimal AST system which -allows the facilities of unit.c to be used: - -1) Make a new directory and cd into it - -2) Get the latest version of AST (V3.3-4) from: - -ftp://ftp.starlink.ac.uk/pub/users-ftp/dsb/ast/V3.3-4/ast.tar.Z - -(I found and fixed a bug in unit.c today whilst I was looking into this) - -3) Execute the following commands: -% uncompress ast.tar.Z -% tar -xf ast.tar ast_source.tar -% tar -xf ast_source.tar \ - ast_err.h \ - channel.h \ - err.h \ - error.h \ - loader.h \ - mapping.h \ - mathmap.h \ - memory.h \ - object.h \ - pointset.h \ - unitmap.h \ - unit.h \ - zoommap.h \ - channel.c \ - error.c \ - err_null.c \ - mapping.c \ - mathmap.c \ - memory.c \ - object.c \ - pointset.c \ - unitmap.c \ - unit.c \ - zoommap.c - -% rm ast_source.tar ast.tar - -4) Copy the files attached to this e-mail into this directory (astTester.c - loader.c matrixmap.h makefile plot.h). - -5) Do: - -% make -% make test - -(you may need to change some of the macro values in makefile if you are -not running on a system like redhat 9). This will create a libast.a -library and run the astTester.c test program. You could look at -astTester.c to see how to use the astUnitMapper function. - -This is the minimal set of AST files needed to use unit.c - it leaves out -all the graphics and the handling of coordinate systems and FITS headers -(and also most of the Mapping classes). - -In case you need to get back to me about this, I'm away on holiday for the -next two weeks. - -David - - - [ Part 2, "" Application/OCTET-STREAM (Name: "wcslib.tar.gz") ] - [ 2.8KB. ] - [ Unable to print this part. ] - - - - |
