This is the VMS version of GNU Make, updated by Hartmut Becker

Changes are based on GNU make 3.82.

. In default.c define variable ARCH as IA64 for VMS on Itanium systems.
|
||||
|
||||
. In makefile.vms avoid name collision for glob and globfree.
|
||||
|
||||
In newer version of the VMS CRTL there are glob and globfree implemented.
|
||||
Compiling and linking may result in
|
||||
|
||||
%ILINK-W-MULDEFLNKG, symbol DECC$GLOBFREE has subsequent linkage definition
|
||||
in module DECC$SHR file SYS$COMMON:[SYSLIB]DECC$SHR.EXE;1
|
||||
%ILINK-W-MULDEF, symbol DECC$GLOBFREE multiply defined
|
||||
in module DECC$SHR file SYS$COMMON:[SYSLIB]DECC$SHR.EXE;1
|
||||
|
||||
linker messages (and similar for DECC$GLOB). The messages just say, that
|
||||
globfree is a known CRTL whose name was mapped by the compiler to
|
||||
DECC$GLOBFREE. This is done in glob.c as well, so this name is defined
|
||||
twice. One possible solution is to use the VMS versions of glob and
|
||||
globfree. However, then the build environment needs to figure out if
|
||||
there is a new CRTL supporting these or not. This adds complexity. Even
|
||||
more, these functions return VMS file specifications, which is not
|
||||
expected by the other make sources. There is a switch at run time (a VMS
|
||||
logical DECC$GLOB_UNIX_STYLE), which can be set to get Unix style
|
||||
names. This may conflict with other software. The recommended solution
|
||||
for this is to set this switch just prior to calling main: in an
|
||||
initialization routine. This adds more complexity and more VMS specific
|
||||
code. It is easier to tell the compiler NOT to map the routine names
|
||||
with a simple change in makefile.vms.
|
||||
|
||||
Some notes on case sensitive names in rules and on the disk. In the VMS
|
||||
template for CONFIG.H case sensitive rules can be enabled with defining
|
||||
WANT_CASE_SENSITIVE_TARGETS. For recent version of VMS there is a case
|
||||
sensitive file system: ODS5. To make use of that, additionally un-defining
|
||||
the HAVE_CASE_INSENSITIVE_FS is required. As these are C macros, different
|
||||
versions of make need to be built to have any case sensitivity for VMS
|
||||
working. Unfortunately, for ODS5 disks that's not all.
|
||||
|
||||
- Usually DCL upcases command line tokens (except strings) and usually the
|
||||
file system is case blind (similar to how Windows systems work)
|
||||
$ set proc/parse=extended/case=sensitive
|
||||
preserves lower and UPPER on the command line and (for this process and all
|
||||
sub-processes) enables case sensitivity in the file system
|
||||
|
||||
- Usually the CRTL tries to reverse what DCL did with command line tokens, it
|
||||
lowercases all tokens (except strings)
|
||||
$ define DECC$ARGV_PARSE_STYLE enable
|
||||
passes (the now preserved) lower and UPPER from the command line to main()
|
||||
|
||||
- Usually the CRTL upcases the arguments to open() and friends
|
||||
$ define DECC$EFS_CASE_PRESERVE enable
|
||||
preserves the names as is.
|
||||
|
||||
It is important to know that not all VMS tools are ready for case sensitivity.
|
||||
With this setup some tools may not work as expected. The setup should not
|
||||
blindly be applied for all users in default login procedures.
|
||||

||||
