This results at least in compile time warnings. - -Changes since GNU make 3.82 + This version of GNU make has been tested on: + OpenVMS V8.3/V8.4 (Alpha) and V8.4 (Integrity) AND V7.3 (VAX) + + This version of GNU Make is intended to be run from DCL to run + make scripts with a special syntax that is described below. It + likely will not be able to run unmodified Unix makefiles. + + There is an older implementation of GNU Make that was ported to GNV. + Work is now in progress to merge that port to get a single version + of GNU Make available. When that merge is done, GNU Make will auto + detect that it is running under a Posix shell and then operate as close to + GNU Make on Unix as possible. + + The descriptions below are for running GNU make from DCL or equivalent. + + +Recipe differences: +------------------- + + GNU Make for OpenVMS can not currently run native Unix make files because of + differences in the implementation that it is not aware of the GNV packages. + + I am trying to document the current behavior in this section. This is based + on the information in the file NEWS. and running the test suite. + TODO: More tests are needed to validate and demonstrate the OpenVMS + expected behavior. + + The format for recipes are a combination of Unix macros, a subset of + simulated UNIX commands, some shell emulation, and OpenVMS commands. + This makes the resulting makefiles unique to the OpenVMS port of GNU make. + + If you are creating a OpenVMS specific makefile from scratch, you should also + look at MMK (Madgoat Make) available at https://github.com/endlesssoftware/mmk + MMK uses full OpenVMS syntax and a persistent subprocess is used for the + recipe lines, allowing multiple line rules. + + The default makefile search order is "makefile.vms", "gnumakefile", + "makefile". TODO: See if that lookup is case sensitive. + + When Make is invoked from DCL, it will create a foreign command + using the name of executable image, with any facility prefix removed, + for the duration of the make program, so it can be used internally + to recursively run make(). The macro MAKE_COMMAND will be set to + this foreign command. + + When make is launched from an exec*() command from a C program, + the foreign command is not created. The macro MAKE_COMMAND will be + set to the actual command passed as argv[0] to the exec*() function. + + If the DCL symbol or logical name GNV$MAKE_USE_MCR exists, then + the macro MAKE_COMMAND will be set to be an "MCR" command with the + absolute path used by DCL to launch make. The foreign command + will not be created. + + The macro MAKE is set to be the same value as the macro MAKE_COMMAND + on all platforms. + + Each recipe command is normally run as a separate spawned processes, + except for the cases documented below where a temporary DCL command + file may be used. + + BUG: Testing has shown that the commands in the temporary command files + are not always created properly. This issue is still under investigation. + + Any macros marked as exported are temporarily created as DCL symbols + for child images to use. DCL symbol substitution is not done with these + commands. + TODO: Add symbol substitution. + + When a temporary DCL command file is used, DCL symbol substitution + will work. + + Command lines of excessive length are broken and written to a command file + in sys$scratch:. There's no limit to the lengths of commands (and no need + for .opt files :-) any more. + + The '<', '>' and '>>' redirection has been implemented by using + temporary command files. These will be described later. + + The DCL symbol or logical name GNV$MAKE_USE_CMD_FILE when set to a + string starting with one of '1','T', or 'E' for "1", "TRUE", or "ENABLE", + then temporary DCL command files are always used for running commands. + In this case, the exported environment environment variables are + created by command file. BUG: Environment variables that hold values + with dollar signs in them are not exported correctly. + + GNU Make generally does text comparisons for the targets and sources. The + make program itself can handle either Unix or OpenVMS format filenames, but + normally does not do any conversions from one format to another. + TODO: The OpenVMS format syntax handling is incomplete. + TODO: ODS-5 EFS support is missing. + BUG: The internal routines to convert filenames to and from OpenVMS format + do not work correctly. + + Note: In the examples below, line continuations such as a backslash may have + been added to make the examples easier to read in this format. + BUG: That feature does not completely work at this time. + + Since the OpenVMS utilities generally expect OpenVMS format paths, you will + usually have to use OpenVMS format paths for rules and targets. + BUG: Relative OpenVMS paths may not work in targets, especially combined + with vpaths. This is because GNU make will just concatenate the directories + as it does on Unix. + + The variables $^ and $@ separate files with commas instead of spaces. + While this may seem the natural thing to do with OpenVMS, it actually + causes problems when trying to use other make functions that expect the + files to be separated by spaces. If you run into this, you need the + following workaround to convert the output. + TODO: Look at have the $^ and $@ use spaces like on Unix and have + and easy to use function to do the conversions and have the built + in OpenVMS specific recipes and macros use it. + + Example: + +comma := , +empty := +space := $(empty) $(empty) + +foo: $(addsuffix .3,$(subs $(comma),$(space),$^) + + + Makefile variables are looked up in the current environment. You can set + symbols or logicals in DCL and evaluate them in the Makefile via + $(<name-of-symbol-or-logical>). Variables defined in the Makefile + override OpenVMS symbols/logicals. + + OpenVMS logical and symbols names show up as "environment" using the + origin function. when the "-e" option is specified, the origion function + shows them as "environment override". On Posix the test scripts indicate + that they should show up just as "environment". + + When GNU make reads in a symbol or logical name into the environment, it + converts any dollar signs found to double dollar signs for convenience in + using DCL symbols and logical names in recipes. When GNU make exports a + DCL symbol for a child process, if the first dollar sign found is followed + by second dollar sign, then all double dollar signs will be convirted to + single dollar signs. + + The variable $(ARCH) is predefined as IA64, ALPHA or VAX respectively. + Makefiles for different OpenVMS systems can now be written by checking + $(ARCH). Since IA64 and ALPHA are similar, usually just a check for + VAX or not VAX is sufficient. + + You may have to update makefiles that assume VAX if not ALPHA. + +ifeq ($(ARCH),VAX) + $(ECHO) "On the VAX" +else + $(ECHO) "On the ALPHA or IA64" +endif + + Empty commands are handled correctly and don't end in a new DCL process. + + The exit command needs to have OpenVMS exit codes. To pass a Posix code + back to the make script, you need to encode it by multiplying it by 8 + and then adding %x1035a002 for a failure code and %x1035a001 for a + success. Make will interpret any posix code other than 0 as a failure. + TODO: Add an option have simulate Posix exit commands in recipes. + + Lexical functions can be used in pipes to simulate shell file test rules. + + Example: + + Posix: +b : c ; [ -f $@ ] || echo >> $@ + + OpenVMS: +b : c ; if f$$search("$@") then pipe open/append xx $@ ; write xx "" ; close xx + + + You can also use pipes and turning messages off to silently test for a + failure. + +x = %x1035a00a + +%.b : %.c +<tab>pipe set mess/nofac/noiden/nosev/notext ; type $^/output=$@ || exit $(x) + + +Runtime issues: + + The OpenVMS C Runtime has a convention for encoding a Posix exit status into + to OpenVMS exit codes. These status codes will have the hex value of + 0x35a000. OpenVMS exit code may also have a hex value of %x10000000 set on + them. This is a flag to tell DCL not to write out the exit code. + + To convert an OpenVMS encoded Posix exit status code to the original code + You subtract %x35a000 and any flags from the OpenVMS code and divide it by 8. + + WARNING: Backward-incompatibility! + The make program exit now returns the same encoded Posix exit code as on + Unix. Previous versions returned the OpenVMS exit status code if that is what + caused the recipe to fail. + TODO: Provide a way for scripts calling make to obtain that OpenVMS status + code. + + Make internally has two error codes, MAKE_FAILURE and MAKE_TROUBLE. These + will have the error "-E-" severity set on exit. + + MAKE_TROUBLE is returned only if the option "-q" or "--question" is used and + has a Posix value of 1 and an OpenVMS status of %x1035a00a. + + MAKE_FAILURE has a Posix value of 2 and an OpenVMS status of %x1035a012. + + Output from GNU make may have single quotes around some values where on + other platforms it does not. Also output that would be in double quotes + on some platforms may show up as single quotes on VMS. + + There may be extra blank lines in the output on VMS. + https://savannah.gnu.org/bugs/?func=detailitem&item_id=41760 + + There may be a "Waiting for unfinished jobs..." show up in the output. + + Error messages generated by Make or Unix utilities may slightly vary from + Posix platforms. Typically the case may be different. + + When make deletes files, on posix platforms it writes out 'rm' and the list + of files. On VMS, only the files are writen out, one per line. + TODO: VMS + + There may be extra leading white space or additional or missing whitespace + in the output of recipes. + + GNU Make uses sys$scratch: for the tempfiles that it creates. + + The OpenVMS CRTL library maps /tmp to sys$scratch if the TMP: logical name + does not exist. As the CRTL may use both sys$scratch: and /tmp internally, + if you define the TMP logical name to be different than SYS$SCRATCH:, + you may end up with only some temporary files in TMP: and some in SYS$SCRATCH: + + The default include directory for including other makefiles is + SYS$SYSROOT:[SYSLIB] (I don't remember why I didn't just use + SYS$LIBRARY: instead; maybe it wouldn't work that way). + TODO: A better default may be desired. + + If the device for a file in a recipe does not exist, on OpenVMS an error + message of "stat: <file>: no such device or address" will be output. + + Make ignores success, informational, or warning errors (-S-, -I-, or + -W-). But it will stop on -E- and -F- errors. (unless you do something + to override this in your makefile, or whatever). + + +Unix compatibilty features: --------------------------- -Fix build problems. - -The new feature "Loadable objects" is not yet supported. If you need it, -please send a change request or submit a bug report. - -The new option --output-sync (-O) is accepted but has no effect: GNU make -for VMS does not support running multiple commands simultaneously. - -Changes for GNU make 3.82 - -Michael Gehre (at VISTEC-SEMI dot COM) supplied a fix for a problem with -timestamps of object modules in OLBs. The timestamps were not correctly -adjusted to GMT based time, if the local VMS time was using a daylight saving -algorithm and if daylight saving was switched off. - -John Eisenbraun (at HP dot COM) supplied fixes and and an enhancement to append -output redirection in action lines. - -Rework of ctrl+c and ctrl+y handling. - -Fix a problem with cached strings, which showed on case-insensitive file -systems. - -Build fixes for const-ified code in VMS specific sources. - -A note on appending the redirected output. With this change, a simple mechanism -is implemented to make ">>" work in action lines. In VMS there is no simple -feature like ">>" to have DCL command or program output redirected and appended -to a file. GNU make for VMS already implements the redirection of output. If -such a redirection is detected, an ">" on the action line, GNU make creates a -DCL command procedure to execute the action and to redirect its output. Based -on that, now ">>" is also recognized and a similar but different command -procedure is created to implement the append. The main idea here is to create a -temporary file which collects the output and which is appended to the wanted -output file. Then the temporary file is deleted. This is all done in the -command procedure to keep changes in make small and simple. This obviously has -some limitations but it seems good enough compared with the current ">" -implementation. (And in my opinion, redirection is not really what GNU make has -to do.) With this approach, it may happen that the temporary file is not yet -appended and is left in SYS$SCRATCH. The temporary file names look like -"CMDxxxxx.". Any time the created command procedure can not complete, this -happens. Pressing Ctrl+Y to abort make is one case. In case of Ctrl+Y the -associated command procedure is left in SYS$SCRATCH as well. Its name is -CMDxxxxx.COM. - -Change in the Ctrl+Y handling. The CtrlY handler now uses $delprc to delete all -children. This way also actions with DCL commands will be stopped. As before -the CtrlY handler then sends SIGQUIT to itself, which is handled in common -code. - -Change in deleteing temporary command files. Temporary command files are now -deleted in the vms child termination handler. That deletes them even if -a Ctrl+C was pressed. - -The behavior of pressing Ctrl+C is not changed. It still has only an effect, -after the current action is terminated. If that doesn't happen or takes too -long, Ctrl+Y should be used instead. - -Changes for GNU make 3.80 - -. In default.c define variable ARCH as IA64 for VMS on Itanium systems. - -. In makefile.vms avoid name collision for glob and globfree. - -This is the VMS port of GNU Make done by Hartmut.Becker@compaq.com. - -It is based on the specific version 3.77k and on 3.78.1. 3.77k was done -by Klaus Kämpf <kkaempf@rmi.de>, the code was based on the VMS port of -GNU Make 3.60 by Mike Moretti. - -It was ported on OpenVMS/Alpha V7.1, DECC V5.7-006. It was re-build and -tested on OpenVMS/Alpha V7.2, OpenVMS/VAX 7.1 and 5.5-2. Different -versions of DECC were used. VAXC was tried: it fails; but it doesn't -seem worth to get it working. There are still some PTRMISMATCH warnings -during the compile. Although perl is working on VMS the test scripts -don't work. The function $shell is still missing. - -There is a known bug in some of the VMS CRTLs. It is in the shipped -versions of VMS V7.2 and V7.2-1 and in the currently (October 1999) -available ECOs for VMS V7.1 and newer versions. It is fixed in versions -shipped with newer VMS versions and all ECO kits after October 1999. It -only shows up during the daylight saving time period (DST): stat() -returns a modification time 1 hour ahead. This results in GNU make -warning messages.
