 * $Log: biglib.rules,v $
 * Revision 1.15  1997/02/28 10:38:29  gunter
 * add a WNT on UseXargs...
 *
 * Revision 1.14  1996/12/16 15:10:08  cernlib
 * Correct logic bug with nested foreach
 *
 * Revision 1.13  1996/11/13 13:24:42  cernlib
 * Changes for shared libraries on OSF: build these from .a and force
 * that .a is up-to-date
 *
 * Revision 1.12  1996/10/29 13:46:48  cernlib
 * building shared libs in progress. Works for HP. AIX and OSF not yet.
 *
 * Revision 1.11  1996/05/09 14:30:03  cernlib
 * Reorder targets such that the targets are:
 * - if the library name is set, this is the first target
 * - if there library name is NIL, then the rules updating objects is first.
 *
 * Use tr instead of sed "-y..." to break lines.
 *
 * Revision 1.10  1996/05/01 13:39:05  cernlib
 * $(VERDIR)/object.list must also depend on the Makefile itsself as a changed
 * makefile could have different LIBDIRS
 *
 * Revision 1.9  1996/05/01 11:54:42  gunter
 * Introduce new way of building libraries.
 * CVS:----------------------------------------------------------------------
 *
 * Revision 1.8  1996/04/11 15:24:01  cernlib
 * small mods
 *
 * Revision 1.7  1996/04/01 15:37:16  cernlib
 * Add _debug and _shared versions of lib to  .PHONY
 * make libname target a :: rule; this was needed to build the data files
 *   together with the library.
 *
 * Revision 1.6  1996/03/14 08:27:21  cernlib
 * Make dependency files depend on Makefile; This forces a recomile if the
 *  Makefile is changed.
 *
 * Revision 1.5  1996/02/14 11:03:35  cernlib
 * add provisions for running tests
 *
# Revision 1.4  1996/02/12  14:21:24  cernlib
# a library now depends (indirectly) on all the objects therein
#
# Revision 1.3  1996/02/08  08:28:18  cernlib
# biglib.rules: add ranlib
#
# Revision 1.2  1996/01/25  11:22:59  cernlib
# Values for IMAKE and MAKEDEPEND are used from env. variables if defined, else
#    from command search path.
# Correct fortran options for local (not archive,..) compilation.
#
# Revision 1.1  1995/12/21  14:07:14  cernlib

/*
 *   rules to build a library from objects in subdirs 
 *   GF. 180895
 *   mod: 081195 more transparent, add debug libraries
 *
 * use this rules with:
 * Imakefile:
 *  SubdirLibraryTarget(libname,subdirlist)
 *  where:   libname:	  name of library to make
 *  	     subdirlist:  list of subdirectories to take $(OBJS) files from
 * 
 * and invoke make with : 
 *   make libname  -or- make libname_debug 
 *   or on Unix : gmake liblibname.a   NOTE: This will not work for
 *                                           _debug/_shared
 * to get library libname up to date.
 *
 *  At the moment ONLY one library per Imakefile/Makefile is allowed.
 * 
 *
 *  make library does:
 *   in rule libname/libname_debug:
 *       i) update stamp/object.list files, this implies that all compiled
 *	    files are up to date, 
 *	ii) rebuild library, if anything changed.
 *          this rebuild is either done: 
 *	      - using the object.list file; this lists all objects for this 
 * 		library. xargs is used to make shure we do not overflow 
 * 		the command line.
 * 	      - visiting all subdirectries recursively, and adding in each 
 * 		directory the objects of this directory.
 *           
 */

/*  the order of SubdirLibrary... is such that 
 *   - if a library is defined, this will be the first target generated
 *   - if NO library is defined, a target updating all objects is first
