This has meant very little for a long time as configure.ac just
hardcoded these values depending on the current OS versions at the
time.
The only place where this is really 'needed' is XlationSvc.c in DtSvc
so that differences between locale specifications on various versions
of an OS can be accounted for. So for now, we just define those when
building DtSvc.
We could probably safely remove them as well with an update to the
Xlate locale DB to remove ancient cruft we don't care about anymore.
For various other modules, like dtlogin, dtsession, etc we just use
the code that was already being used due to the hardcoded values we've
had for the last 10-ish years.
This patch removes instances of hardcoded
invocation of /bin/ksh and allows to
replace it with, for, example,
/usr/local/bin/ksh93
Also "ksh93" is accepted whenever "ksh" is.
Tested using the following /bin/ksh:
----8<----
WHAT=`ps -o command= -p $PPID`
msg="Something tried to call /bin/ksh: $PPID: $WHAT"
print -u2 "$msg"
logger user.warn "$msg"
exit 99
----8<----
(Warning: first two lines are FreeBSD specific)
Scripts from Makefiles should now be executed either
with
$(KORNSHELL) korn-shell-script
or
$(SHELL) bourne-shell-script
therefore #!/bin/ksh has not been changed everywhere.
/usr/dt/bin/ scripts have been converted (e.g. Xsession)
Whenever possible Imake and CPP facilities have been used.
For C and C++ programs KORNSHELL needs to be defined to
"/path/to/your/ksh" (with quotes) so that it can make
a valid C constant.
Therefore, when adding KORNSHELL to Imakefile for C files,
you have to add
CXXEXTRA_DEFINES = -DKORNSHELL=\"$(KORNSHELL)\"
or similar (for example, see programs/dtprintinfo)
But for simple shell script substitution we usually change
LOCAL_CPP_DEFINES = -DCDE_CONFIGURATION_TOP=$(CDE_CONFIGURATION_TOP) \
-DCDE_INSTALLATION_TOP=$(CDE_INSTALLATION_TOP) \
-DCDE_LOGFILES_TOP=$(CDE_LOGFILES_TOP)
to:
LOCAL_CPP_DEFINES = -DCDE_CONFIGURATION_TOP=$(CDE_CONFIGURATION_TOP) \
-DCDE_INSTALLATION_TOP=$(CDE_INSTALLATION_TOP) \
-DCDE_LOGFILES_TOP=$(CDE_LOGFILES_TOP) \
-DKORNSHELL=$(KORNSHELL) \
-DXPROJECTROOT=X11ProjectRoot
since we don't want quotes for shell scripts.
