X# X# Location: You can obtain a copy of the patch from watmsg.uwaterloo.edu X# via anonymous ftp from the directory pub/dmake. The file is X# dmake37-patch2.Z. The patch is also submitted for posting X# to comp.sources.misc. X# X# Application: Change directory to the source directory containing the X# dmake sources and run the patch through /bin/sh. It constructs X# any required subdirectories and applies the patch program as X# needed to apply patches to files. If you obtain the patch X# files from a news group then you must first build the patch X# source by running all parts of the patch through unshar or X# /bin/sh. X# X# Acknowledgment: Thanks to everyone who wrote with suggestions or bug fixes. X# In most cases your fixes and/or suggestions were X# incorporated into the sources. Your continued input makes X# dmake a better tool. X# X# X# DETAILS OF FIXES: X# ----------------- X# - Fixed a bug in function.c. If you used a $(shell ...) macro in a line X# which got expanded from within the input buffer Buffer (eg. in a rule X# definition) nasty things could happen since _exec_shell re-used Buffer X# when it shouldn't have. X# X# - Made sure that -v and -n flags do not take effect across a $(shell ...) X# macro expansion. This ensures that $(shell ...) recipes are always X# executed when the macro is expanded and never contain noise from a -v X# flag. Dunno how I missed this the first time around. X# X# - Fixed a bug that set Current_target to NULL when making successive recipe X# lines individually. This meant that temp files were being deleted late, X# possibly from the wrong places, and hence not deleted at all. X# X# - Fixed several inference bugs. Nothing too major: X# X# 1. a recipe of the form X# %.foo: X# @[ X# stuff ... X# ] X# didn't get the group recipe attribute attached to the %.foo node X# so when the inference algorithm was run it failed to attach the X# correct attribute to go along with the new recipe. X# X# 2. Inference algorithm now marks for REMOVAL, ALL intermediate nodes X# (it did this before too -- but by luck), and marks ALL nodes as X# TARGETS, and all but the first node as being INFERRED. I doubt X# that anyone will notice these changes. I had to have a really X# screwy makefile to find the bug. X# X# - Fixed $(shell ...) macro so that it can be nested to arbitrary depths. X# It uses a single temporary file for the purpose and keeps reusing it for X# each nested instance. Works like a charm. X# X# - Fixed bug in rulparse.c where an attribute flag variable was of type X# int and not t_attr as it should be. This caused problems on 16-bit X# machines (reported by lots of people). X# X# - Fixed a bug reported by paul@halserv2.hal.com, dmake.c line 373, would X# dereference a NULL pointer if the hash table didn't contain an entry. X# X# - Fixed a bug reported by paul@halserv2.hal.com, rulparse.c line 949 X# would dereference a NULL pointer if it tried to match a certain sequence X# of %-meta rules. X# X# - Fixed a bug reported by paul@halserv2.hal.com, make.c, the SET_TOKEN X# call was getting called with a NULL pointer. X# X# - Minor tweaks to the OS/2 scripts as reported by Frank Waley. Should make X# MSC compiles work now. X# X# - Changed sysvr4/stdarg.h to ensure that va_dcl is defined. X# X# - Modified man page. The diffs would have been bigger than the source so X# I just included new copies. X# X# X# X# DETAILS OF ADDITIONS/CHANGES: X# ----------------------------- X# - Added a sysvr3/pwd directory along with getcwd.c. The reason for this X# addition is to hopefully eliminate once and for all the annoying X# "lost a child" bug. If you see this bug appear then remake dmake with X# X# make sysvr3pwd X# or make xenixpwd X# X# Both create a version of dmake that uses a local version of getcwd rather X# than the C-library version. Thanks to Gwyn Dyer for providing the code X# to getcwd.c. I used his version as it compiled on a xenix machine and X# seemed to be the more widely used one. Thanks to all that sent me copies X# of it. I hope this gets rid of the lost child issue once and for all. X# X# - The MSDOS version now behaves identically to the UNIX versions when X# running recipes containing embedded cd calls. I changed dmake to restore X# the directory it was in prior to invoking a child process. X# X# The following recipe will now behave identically under UNIX and DOS X# X# all: X# cd foo; make ... X# cd fee; make ... X# X# Previously to this change, the DOS version of DMAKE would have been in X# the foo directory after the first line of the recipe, and would not X# find fee. X# X# - Added the -B flag. This is in response to several requests at supporting X# spaces in front of recipe lines. This does not come without a price. X# By default the flag is off and tabs are required to start recipe lines X# unless it is a group recipe. If you turn the flag on, either through X# supplying -B on the command line or by putting ".NOTABS := y" in the X# makefile then when dmake scans non-group recipes they are terminated at X# the first line that is only white space or contains no leading white space X# and is either a macro definition or a rule definition. X# X# Consider the following makefile: X# X# all: X# <tab> echo hi there X# <space>echo e:test X# <tab> echo hello X# X# By default the recipe for all is simply: "echo hi there", and the remaining X# two lines are parsed as a new rule definition with the associated recipe X# being "echo hello". If you supply -B, then the recipe for 'all' is all X# three lines above, since the second recipe line now begins with a space. X# X# If you change the makefile to contain: X# X# all: X# <tab> echo hi there X# X# <space>echo e:test X# <tab> echo hi there X# X# then the -B flag has no visible effect. The makefile is parsed the X# same in both cases as the first recipe is terminated by the empty line. X# or a valid recipe rule. X# X# If you now change the makefile to contain: X# X# all: X# <tab> echo hi there X# X# <tab> echo e:test X# <tab> echo hi there X# X# then by default all three lines form the recipe for 'all'. X# Specifying -B terminates the first recipe after the first line and begins X# a new rule definition with the line "echo e:test". X# X# In summary: X# By default: (no -B) a recipe is terminated by a line containing some X# text that does not begin with a <tab>. X# X# Specify -B: A recipe is terminated by a line that is only white space X# or by a line containg text that contains NO leading X# white space. X# X# You can use the .NOTABS macro to set/reset this behaviour at will from X# within a makefile. See the man page. X# X# - Added OSRELEASE=coherent targets and directories to support Coherent X# systems. Patches provided by David Fenyes (dfenyes@thesis1.med.uth.tmc.edu). X# X# - Added OSRELEASE=msdos OSENVIRONMENT=ztcdos targets and directories to X# support making of dmake using Zortech C++ 2.1. Patches provided by X# David Engel (ods@utdallas.edu). X# X# Remove Obsolete files from distribution X X# Now use a shar archive to add any new files to the distribution X# This is a shell archive (produced by shar 3.49) X# To extract the files from this archive, save it to a file, remove X# everything above the "!/bin/sh" line above, and type "sh file_name".

Each target XX may depend on zero or more prerequisite targets. If any of XX the target's prerequisites is newer than the target or if XX the target itself does not exist, then ddmmaakkee will attempt to XX make the target. XX XX If no --ff command line option is present then ddmmaakkee searches XX for an existing _m_a_k_e_f_i_l_e from the list of prerequisites XX specified for the special target _._M_A_K_E_F_I_L_E_S (see the STARTUP XX section for more details). If "-" is the name of the file XX specified to the --ff flag then ddmmaakkee uses standard input as XX the source of the makefile text. XX XX Any macro definitions (arguments with embedded "=" signs) XX that appear on the command line are processed first and XX supersede definitions for macros of the same name found XX within the makefile. In general it is impossible for defin- XX itions found inside the makefile to redefine a macro defined XX on the command line, see the MACROS section for an excep- XX tion. XX XX If no _t_a_r_g_e_t names are specified on the command line, then XX ddmmaakkee uses the first non-special target found in the XX makefile as the default target. See the SSPPEECCIIAALL TTAARRGGEETTSS XX section for the list of special targets and their function. XX ddmmaakkee is a re-implementation of the UNIX Make utility with XX significant enhancements. Makefiles written for most previ- XX ous versions of _M_a_k_e will be handled correctly by ddmmaakkee.. XX Known differences between ddmmaakkee and other versions of make XX are discussed in the CCOOMMPPAATTIIBBIILLIITTYY section found at the end XX of this document. XX XOOPPTTIIOONNSS XX --AA Enable AUGMAKE special inference rule transformations XX (see the "PERCENT(%) RULES" section), these are set to XX off by default. XX XX --BB Enable the use of spaces instead of <tabs> to begin XX recipe lines. This flag equivalent to the .NOTABS spe- XX cial macro and is further described below. XX XX --cc Use non-standard comment stripping. If you specify --cc XX then ddmmaakkee will treat any ## character as a start of XX XX XX XVersion 3.70 UW 1 XX XX XX XX XDMAKE(p) Unsupported Free Software DMAKE(p) XX XX XX XX comment character wherever it may appear unless it is XX escaped by a \. XX XX --CC [[++]]ffiillee XX This option writes to _f_i_l_e a copy of standard output XX and standard error from any child processes and from XX the ddmmaakkee process itself. If you specify a ++ prior to XX the file name then the text is appended to the previous XX contents of _f_i_l_e. This option is active in the MSDOS XX implementation only and is ignored by non-MSDOS ver- XX sions of ddmmaakkee.. XX XX --ee Read the environment and define all strings of the form XX 'EENNVV--VVAARR=_e_v_a_l_u_e' defined within as macros whose name is XX EENNVV--VVAARR, and whose value is '_e_v_a_l_u_e'. The environment XX is processed prior to processing the user specified XX makefile thereby allowing definitions in the makefile XX to override definitions in the environment. XX XX --EE Same as -e, except that the environment is processed XX after the user specified makefile has been processed XX (thus definitions in the environment override defini- XX tions in the makefile). The -e and -E options are XX mutually exclusive. If both are given the latter takes XX effect. XX XX --ff ffiillee XX Use ffiillee as the source for the makefile text. Only one XX --ff option is allowed. XX XX --hh Print the command summary for ddmmaakkee. XX XX --ii Tells ddmmaakkee to ignore errors, and continue making other XX targets. This is equivalent to the .IGNORE attribute XX or macro. XX XX --KK ffiillee XX Turns on ..KKEEEEPP__SSTTAATTEE state tracking and tells ddmmaakkee to XX use _f_i_l_e as the state file. XX XX --kk Causes ddmmaakkee to ignore errors caused by command execu- XX tion and to make all targets not depending on targets XX that could not be made. Ordinarily ddmmaakkee stops after a XX command returns a non-zero status, specifying --kk causes XX ddmmaakkee to ignore the error and continue to make as much XX as possible. XX XX --nn Causes ddmmaakkee to print out what it would have executed, XX but does not actually execute the commands. A special XX check is made for the string "$(MAKE)" inside a recipe XX line, if found, the line is expanded and invoked, XX thereby enabling recursive makes to give a full XX XX XX XVersion 3.70 UW 2 XX XX XX XX XDMAKE(p) Unsupported Free Software DMAKE(p) XX XX XX XX description of all that they will do. The check for XX "$(MAKE)" is disabled inside group recipes. XX XX --pp Print out a version of the digested makefile in human XX readable form. (useful for debugging, but cannot be XX re-read by ddmmaakkee) XX XX --PP## On systems that support multi-processing cause ddmmaakkee to XX use _# concurrent child processes to make targets. See XX the "MULTI PROCESSING" section for more information. XX XX --qq Check and see if the target is up to date. Exits with XX code 0 if up to date, 1 otherwise. XX XX --rr Tells ddmmaakkee not to read the initial startup makefile, XX see STARTUP section for more details. XX XX --ss Tells ddmmaakkee to do all its work silently and not echo XX the commands it is executing to stdout (also suppresses XX warnings). This is equivalent to the .SILENT attri- XX bute or macro. XX XX --SS Force sequential execution of recipes on architectures XX which support concurrent makes. For backward compati- XX bility with old makefiles that have nasty side-effect XX prerequisite dependencies. XX XX --tt Causes ddmmaakkee to touch the targets and bring them up to XX date without executing any commands. XX XX --TT Tells ddmmaakkee to not perform transitive closure on the XX inference graph. XX XX --uu Force an unconditional update. (ie. do everything that XX would be done if everything that a target depended on XX was out of date) XX XX --vv[[ddffiimmtt]] XX Verbose flag, when making targets print to stdout what XX we are going to make and what we think its time stamp XX is. The optional flags [[ddffiimmtt]] can be used to restrict XX the information that is displayed. In the absence of XX any optional flags all are assumed to be given (ie. --vv XX is equivalent to --vvddffiimmtt). The meanings of the XX optional flags are: XX XX dd Notify of change directory operations only. XX XX ff Notify of file I/O operations only. XX XX ii Notify of inference algorithm operation only. XX XX XX XX XVersion 3.70 UW 3 XX XX XX XX XDMAKE(p) Unsupported Free Software DMAKE(p) XX XX XX XX mm Notify of target update operations only. XX XX tt Keep any temporary files created; normally they XX are automatically deleted. XX XX --VV Print the version of ddmmaakkee, and values of builtin mac- XX ros. XX XX --xx Upon processing the user makefile export all non- XX internally defined macros to the user's environment. XX This option together with the -e option allows SYSV XX AUGMAKE recursive makes to function as expected.

XX XX AAUUTTHHOORR The guy responsible for this thing. XX XX BBUUGGSS Hope not. XX XSSTTAARRTTUUPP XX When ddmmaakkee begins execution it first processes the command XX line and then processes an initial startup-makefile. This XX is followed by an attempt to locate and process a user sup- XX plied makefile. The startup file defines the default values XX of all required control macros and the set of default rules XX XX XX XVersion 3.70 UW 5 XX XX XX XX XDMAKE(p) Unsupported Free Software DMAKE(p) XX XX XX XX for making targets and inferences. When searching for the XX startup makefile, ddmmaakkee searches the following locations, in XX the order specified, until a startup file is located: XX XX 1. The location given as the value of the macro MAK- XX ESTARTUP defined on the command line. XX XX 2. The location given as the value of the environment XX variable MAKESTARTUP defined in the current XX environment. XX XX 3. The location given as the value of the macro MAK- XX ESTARTUP defined internally within ddmmaakkee. XX XX The above search is disabled by specifying the -r option on XX the command line. An error is issued if a startup makefile XX cannot be found and the -r option was not specified. A user XX may substitute a custom startup file by defining the MAKES- XX TARTUP environment variable or by redefining the MAKESTARTUP XX macro on the command line. To determine where ddmmaakkee looks XX for the default startup file, check your environment or XX issue the command _"_d_m_a_k_e _-_V_". XX XX A similar search is performed to locate a default user XX makefile when no --ff command line option is specified. By XX default, the prerequisite list of the special target XX .MAKEFILES specifies the names of possible makefiles and the XX search order that ddmmaakkee should use to determine if one XX exists. A typical definition for this target is: XX XX .MAKEFILES : makefile.mk Makefile makefile XX XX ddmmaakkee will first look for makefile.mk and then the others. XX If a prerequisite cannot be found ddmmaakkee will try to make it XX before going on to the next prerequisite. For example, XX makefile.mk can be checked out of an RCS file if the proper XX rules for doing so are defined in the startup file. XX XSSYYNNTTAAXX XX This section is a summary of the syntax of makefile state- XX ments. The description is given in a style similar to BNF, XX where { } enclose items that may appear zero or more times, XX and [ ] enclose items that are optional. Alternative pro- XX ductions for a left hand side are indicated by '->', and XX newlines are significant. All symbols in bboolldd type are text XX or names representing text supplied by the user.

MMAACCRROO, PPRREERREEQQUUIISSIITTEE, and TTAARRGGEETT each XX represent a string of characters not including space or tab XX which respectively form the name of a macro, prerequisite or XX target. The name may itself be a macro expansion expres- XX sion. A LLIINNEE can be continued over several physical lines XX by terminating it with a single backslash character. Com- XX ments are initiated by the pound ## character and extend to XX the end of line. All comment text is discarded, a '#' may XX be placed into the makefile text by escaping it with '\' XX (ie. \# translates to # when it is parsed). An exception to XX this occurs when a # is seen inside a recipe line that XX XX XX XVersion 3.70 UW 8 XX XX XX XX XDMAKE(p) Unsupported Free Software DMAKE(p) XX XX XX XX begins with a <tab> or is inside a group recipe. If you XX specify the --cc command line switch then this behavior is XX disabled and ddmmaakkee will treat all # characters as start of XX comment indicators unless they are escaped by \. A set of XX continued lines may be commented out by placing a single # XX at the start of the first line. A continued line cannot XX span more than one makefile. XX XX wwhhiittee ssppaaccee is defined to be any combination of <space>, XX <tab>, and the sequence \<nl> when \<nl> is used to ter- XX minate a LINE. When processing mmaaccrroo definition lines, any XX amount of white space is allowed on either side of the macro XX operator (=, *=, :=, *:=, += or +:=), and white space is XX stripped from both before and after the macro value string. XX The sequence \<nl> is treated as white space during recipe XX expansion and is deleted from the final recipe string. You XX must escape the \<nl> with another \ in order to get a \ at XX the end of a recipe line. The \<nl> sequence is deleted XX from macro values when they are expanded. XX XX When processing ttaarrggeett definition lines, the recipe for a XX target must, in general, follow the first definition of the XX target (See the RULES AND TARGETS section for an exception), XX and the recipe may not span across multiple makefiles. Any XX targets and prerequisites found on a target definition line XX are taken to be white space separated tokens. The rule XX operator (_o_p in SYNTAX section) is also considered to be a XX token but does not require white space to precede or follow XX it. Since the rule operator begins with a `:', traditional XX versions of make do not allow the `:' character to form a XX valid target name. ddmmaakkee allows `:' to be present in XX target/prerequisite names as long as the entire XX target/prerequisite name is quoted. For example: XX XX a:fred : test XX XX would be parsed as TARGET = a, PREREQUISITES={fred, :, XX test}, which is not what was intended. To fix this you must XX write: XX XX "a:fred" : test XX XX Which will be parsed as expected. See the EXAMPLES section XX for how to apply "" quoting to a list of targets. XX XAATTTTRRIIBBUUTTEESS XX ddmmaakkee defines several target attributes. Attributes may be XX assigned to a single target, a group of targets, or to all XX targets in the makefile. Attributes are used to modify XX ddmmaakkee actions during target update. The recognized attri- XX butes are: XX XX XX XX XVersion 3.70 UW 9 XX XX XX XX XDMAKE(p) Unsupported Free Software DMAKE(p) XX XX XX XX ..EEPPIILLOOGG Insert shell epilog code when executing a group XX recipe associated with any target having this XX attribute set. XX XX ..IIGGNNOORREE Ignore an error when trying to make any target XX with this attribute set. XX XX ..LLIIBBRRAARRYY Target is a library. XX XX ..MMKKSSAARRGGSS If running in an MSDOS environment then use MKS XX extended argument passing conventions to pass XX arguments to commands. Non-MSDOS environments XX ignore this attribute. XX XX ..NNOOIINNFFEERR Any target with this attribute set will not be XX subjected to transitive closure if it is XX inferred as a prerequisite of a target whose XX recipe and prerequisites are being inferred. XX (i.e. the inference algorithm will not use any XX prerequisite with this attribute set, as a tar- XX get) If specified as '.NOINFER:' (ie. with no XX prerequisites or targets) then the effect is XX equivalent to specifying --TT on the command line. XX XX ..NNOOSSTTAATTEE Any target with this attribute set will not have XX command line flag information stored in the XX state file if .KEEP_STATE has been enabled. XX XX ..PPHHOONNYY Any target with this attribute set will have its XX recipe executed each time the target is made XX even if a file matching the target name can be XX located. Any targets that have a .PHONY attri- XX buted target as a prerequisite will be made each XX time the .PHONY attributed prerequisite is made. XX XX ..PPRREECCIIOOUUSS Do not remove associated target under any cir- XX cumstances. Set by default for any targets XX whose corresponding files exist in the file sys- XX tem prior to the execution of ddmmaakkee. XX XX ..PPRROOLLOOGG Insert shell prolog code when executing a group XX recipe associated with any target having this XX attribute set. XX XX ..SSEEQQUUEENNTTIIAALL Force a sequential make of the associated XX target's prerequisites. XX XX ..SSEETTDDIIRR Change current working directory to specified XX directory when making the associated target. XX You must specify the directory at the time the XX attribute is specified. To do this simply give XX _._S_E_T_D_I_R_=_p_a_t_h as the attribute. _p_a_t_h is expanded XX XX XX XVersion 3.70 UW 10 XX XX XX XX XDMAKE(p) Unsupported Free Software DMAKE(p) XX XX XX XX and the result is used as the value of the XX directory to change to. If path is surrounded XX by single quotes then path is not expanded, and XX is used literally as the directory name.
