- # TITLE: Intel Librarian input-file object file extractor
- # DATE: 09/28/1989;
- # VERSION: 1.1;
- # DESCRIPTION: "An AWK program which scans a librarian input-file
- # and builds a batch file which will in turn
- # produce a make-file. Requires the services of a
- # source-file dependency generator (such as cincdep)."
- # KEYWORDS: Makefile, make, include, dependency generator;
- # SYSTEM: MS-DOS;
- # WARNINGS: "PolyAwk will generate false matches to lines
- # beginning with non-ASCII (i.e. 128..256) chars."
- # FILENAME: LBI2MAK.AWK;
- # SEE-ALSO: CINCDEP.AWK, TLR2MAK.AWK, AINCDEP.AWK, PINCDEP.AWK;
- # AUTHORS: James Yehle;
- # COMPILERS: PolyAWK, Mortice Kern AWK, Rob Duff's PC-AWK 2.0;

- # Scans an Intel library make (from scratch) input file to produce
- # to produce a batch file for use with dependency generator(s)
- # to build a set of make-file dependency lists (and eventually a make-file)

- # 1.1 Sep 10 89 JRY Added legal-filename-char regular expression
- # 1.0 Sep 10 89 JRY Initial creation--from cf2mak.awk v 1.6

- #
- # Usage is:
- # awk -f lbi2mak.awk filename.lbi outfile=[path]filename
- # lc=command lcf=[p][n][e] [>batchfile]
- # where outfile gets the conglomerated dependency generator output
- # Order of command-line parameters (save for "-f ..."
- # and ">batchfile") is irrelevant, but identifiers must be in lower case.
- # lc is the compile command (no spaces allowed)
- # lcf controls which components of the source file's name get
- # included in the link command line: p = directory path,
- # n = name, e = extension.
- # . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- #
- # Takes an Intel librarian input file as input.
- # Generates an executable-dependency list at the start of outfile,
- # followed by the link command and the primary (executable) file name.
- # Extracts all object files which are to be added to the library.
- # Generates a batch file line, for each object file found, of the form:
- # comdpre srcfile "incpath="incpath "objname="file.obj
- # "cc="cc "ccf="ccf comdmid outfile comdpost
- # unless the source file can't be found, in which case it makes this batch file line:
- # comdpre "__NOFILE__ objname="file.obj "cc= ccf= " comdmid outfile comdpost
- # The search for source files covers C, assembly, and PL/M path and extensions.
- #
- # Assumes object file names contain only these chars: [^\\]*.[Oo][Bb][Jj]
- # Assumes FILENAME ends with .LBI or .lbi and that primary target (library)
- # file name is made by replacing .LBI with exe_ext.

- # Set various strings used in building batch-file command lines
- # (these should probably get passed in as lbi2mak command-line arguments)
-
- # Lbi2mak supports several languages. Each language must have
- # 1) a source file name extension (to replace ".obj" in searches)
- # 2) a source directory pathname (stuck on front of file name during search)
- # 3) an include-file directory whose name to pass to a dependency scanner
- # 4) a compiler command to pass to dependency scanner (no spaces allowed)
- # 5) controls for filename pathname/extension inclusion in compile command line
- # 6) a dependency generator awk program
