#Example of most capabilities of Solucorp Make

#Solve DOS command line limitation for command.
#    It tells make how to create a command file, how to insert
#    continuation character, and how to call the utility.
#    for now on cc and lib may accept command line of any length.

#    except main.c

# See the comments in the .c.$(OBJEXT) rule

#    macro DIROBJ will hold a path. This path will be any of three possible.
#    The first one that exist will be used.

#General rules
#    lib.lib is builted from .obj file, not .c. Macro SOURCE holds a list
#    of .c. This syntax allows editing of the list.
#    The builtin macro $? let you update the librairie
#    with only .obj (.o) files which outdated lib.lib (lib.a).

#Documentation preparation.
#    Here is the sequence that has been used to create the files
#    that are documented in document.exm.
doc:
    proto -cod -fxsys.nap *.c           # Produce xsys.nap file
    naperm xsys.nap xsys.nai xsys.nas xsys.nah
    nadoc xsys.doc xsys.nap xsys.ref    # Produce the reference manual

#Automatic dependancies creation.
#    The file makefile.dep is created by scanning all the sources in
#    the current directory. This file is silently processed by
#    Make to establish the dependancies between source files and headers.
dep:
    makedep makefile *.c
