NAME

       remake - A patched GNU make with a debuger, better tracing and error reporting

SYNOPSIS

       remake [ -f makefile ] [ options ] ... [ targets ] ...

WARNING

       This  man  page	is  an	extract  of  the documentation of GNU remake ( make + debugger).  It is updated only occasionally, because the GNU
       project does not use nroff.  For complete, current documentation, refer to the Info file make.info and mdb.info which  are  made  from  the
       Texinfo source files make.texi.	and mdb.texi The latter describes debugger behavior.

DESCRIPTION

       The purpose of the make utility is to determine automatically which pieces of a large program need to be recompiled, and issue the commands
       to recompile them. See documentation on GNU make for more information.

       However in this patched version we add a debugger which can be entered either initially (option -X or --debugger) or on an error  (--debug-
       ger=error).  We	also add better tracing facilities (option -x) and we report postion information better. When an error is encountered more
       information is given automatically.

       See also the home <http://bashdb.sf.net/remake> page for more information.

OPTIONS

       -b, -m
	    These options are ignored for compatibility with other versions of make.

       -B, --always-make
	    Unconditionally make all targets.

       -C dir, --directory=dir
	    Change to directory dir before reading the makefiles or doing anything else.  If multiple -C options are  specified,  each	is  inter-
	    preted relative to the previous one: -C / -C etc is equivalent to -C /etc.	This is typically used with recursive invocations of make.

       -d   Print  debugging  information  in  addition to normal processing.  The debugging information says which files are being considered for
	    remaking, which file-times are being compared and with what results, which files actually need to be remade, which implicit rules  are
	    considered and which are applied---everything interesting about how make decides what to do.

       --debug[=FLAGS]
	    Print  debugging  information  in addition to normal processing.  If the FLAGS are omitted, then the behavior is the same as if -d was
	    specified.	FLAGS may be a for all debugging output (same as using -d), b for basic debugging, v for more verbose basic  debugging,  i
	    for showing implicit rules, j for details on invocation of commands, and m for debugging while remaking makefiles.

       --debugger[=FLAGS]
	    Enter  the debugger.  If the FLAGS are omitted, then the behavior is the same as if --debugger=full was specified.	FLAGS may be a for
	    all debugging output (same as using -d), error the debugger is only entered on encountering an error. It may be possible to  quit  the
	    debugger  and continue processing. So the overall effect could be like the " --keep-going" switch.	fatal the debugger is only entered
	    on encountering a fatal error.  preread the debugger is entered after command-line options are parsed but before andy  Makefiles  have
	    been  read.  It  also sets step-tracing mode.  preaction Enters the debugger after command-line options are parsed and after Makefiles
	    have been read, but before any action is performed. It also sets step-tracing mode.  full for basic debugging,

       -e, --environment-overrides
	    Give variables taken from the environment precedence over variables from makefiles.

       +-f file, --file=file, --makefile=FILE
	    Use file as a makefile.

       -i, --ignore-errors
	    Ignore all errors in commands executed to remake files.

       -I dir, --include-dir=dir
	    Specifies a directory dir to search for included makefiles.  If several -I options are used to specify several directories, the direc-
	    tories  are  searched  in  the order specified.  Unlike the arguments to other flags of make, directories given with -I flags may come
	    directly after the flag: -Idir is allowed, as well as -I dir.  This syntax is allowed for compatibility with the C	preprocessor's	-I
	    flag.

       -j [jobs], --jobs[=jobs]
	    Specifies  the  number  of jobs (commands) to run simultaneously.  If there is more than one -j option, the last one is effective.	If
	    the -j option is given without an argument, remake will not limit the number of jobs that can run simultaneously.

       -k, --keep-going
	    Continue as much as possible after an error.  While the target that failed, and those that depend on it, cannot be remade,	the  other
	    dependencies of these targets can be processed all the same.

       -l [load], --load-average[=load]
	    Specifies  that  no  new  jobs  (commands) should be started if there are others jobs running and the load average is at least load (a
	    floating-point number).  With no argument, removes a previous load limit.

       -L, --check-symlink-times
	    Use the latest mtime between symlinks and target.

       -n, --just-print, --dry-run, --recon
	    Print the commands that would be executed, but do not execute them.

       -o file, --old-file=file, --assume-old=file
	    Do not remake the file file even if it is older than its dependencies, and do not remake anything  on  account  of	changes  in  file.
	    Essentially the file is treated as very old and its rules are ignored.

       -p, --print-data-base
	    Print  the data base (rules and variable values) that results from reading the makefiles; then execute as usual or as otherwise speci-
	    fied.  This also prints the version information given by the -v switch (see below).  To print the data base without trying	to  remake
	    any files, use remake -p -f/dev/null.

       -q, --question
	    ``Question	mode''.   Do not run any commands, or print anything; just return an exit status that is zero if the specified targets are
	    already up to date, nonzero otherwise.

       -r, --no-builtin-rules
	    Eliminate use of the built-in implicit rules.  Also clear out the default list of suffixes for suffix rules.

       -R, --no-builtin-variables
	    Don't define any built-in variables.

       -s, --silent, --quiet
	    Silent operation; do not print the commands as they are executed.

       -S, --no-keep-going, --stop
	    Cancel the effect of the -k option.  This is never necessary except in a recursive make where -k might be inherited from the top-level
	    make via MAKEFLAGS or if you set -k in MAKEFLAGS in your environment.

       -t, --touch
	    Touch  files  (mark them up to date without really changing them) instead of running their commands.  This is used to pretend that the
	    commands were done, in order to fool future invocations of remake.

       -v, --version
	    Print the version of the make program plus a copyright, a list of authors and a notice that there is no warranty.

       -w, --print-directory
	    Print a message containing the working directory before and after other processing.  This may be useful for tracking down errors  from
	    complicated nests of recursive make commands.

       --no-print-directory
	    Turn off -w, even if it was turned on implicitly.

       -W file, --what-if=file, --new-file=file, --assume-new=file
	    Pretend that the target file has just been modified.  When used with the -n flag, this shows you what would happen if you were to mod-
	    ify that file.  Without -n, it is almost the same as running a touch command on the given file before running make,  except  that  the
	    modification time is changed only in the imagination of make.

       -x, --trace [=FLAGS]
	    Sets up execution tracing. If FLAGS are omitted, then the behavior is the same as if " --trace=full" was specified.  full normal trac-
	    ing read show in addition status on reading in makefiles full the most verbose tracing.

       --warn-undefined-variables
	    Warn when an undefined variable is referenced.

EXIT STATUS

       GNU remake exits with a status of zero if all makefiles were successfully parsed and no targets that were built failed.	A  status  of  one
       will  be  returned  if the -q flag was used and make determines that a target needs to be rebuilt.  A status of two will be returned if any
       errors were encountered. An exit status of 77 can be given when quitting from the debugger out of a recursive invocation.
