There is no need to touch the state of vars in child anyway.
Change 2nd arg to Var_Export1() to indicate if we are the parent or child,
and only set flags in the parent.
executable. Remove this so that different compiles can be binary
compared. rcsid's for all files are already embedded in the executable
so versions can be easily distinguished. (I didn't catch this on
previous passes because I did my builds on the same day.)
Note: there's a special rule for main.o in Makefile with a purpose I
can't actually discern -- I think it isn't needed, and I've flagged it
with a comment.
(and similarly for the other .ifxxx).
Do comparison against "" or 0 for .if "foo" and .if <numeric> directly
instead of faking up the operator string.
Rename error: to done: and use it for more exit paths.
Elucidate and correct some comments.
Fixes problems with makefiles that do:
.for var in var_1 var_2
.ifdef ${var}
...
which used to check whether var_1 was defined - because the .ifdef saw the
literal var_1, not a variable expansion due to the way .for loop variables
were substituted.
applies to the variable name, not its value!
Remove the set of examples that were recently added that failed to
explain why some worked and some didn't.
Add a not to the compatability section about the change in .for loop
substitution post 5.0.
Add a BUGS section.
XXX the BUGS section needs more entries :-)
argument to be exclosed in (...).
'.if exists()' is parsed as '.ifdef exists()' and the ')' must not be
left over at the end.
I have no idea why any of my recent changes have affected this.
But pkgsrc/mk/compiler/gcc.mk (line 488) does .if exists(${FCPATH})
even though FCPATH is only set when the file exists.
Saves having to malloc/free a fixed size structure.
Buf_Init() now takes ptr to Buffer to initialiase.
Change Buf_Destroy() to return ptr to string when not freed.
Remove large number of casts to (Byte) and (Byte *) - 'Byte' is 'char' here.
Buf_AddByte[s] guarantees that the data is 0 termininated, so never add '\0'.
Keep 'count' not 'left' and 'inPtr', code is simplier with only one update.
Fix fallou, no functional change.
variable references - eg ${.TARGET} since that can't be expanded earlier.
Also the variable gets re-expanded before modifiers are applied.
All this means that we do need to let :U expand variables and must not
just escape $.
as well as ':' and '}' or ')'.
The parameters have just been expanded (and will be expanded again) later
so don't need expanding as part of the :U process.
Seems to fix pkgsrc breakage at line 34 of bsd.pkginstall.mk doing:
.for i in ${PKG_USERS}
_PKG_VARS.pkginstall+= PKG_UID.${u} PKG_GECOS.${u} PKG_HOME.${u} PKG_SHELL.${u}
.endfor
when PKG_USERS = ${AVAHI_USER}:${AVAHI_GROUP}::Avahi\ user:/nonexistent
(set at line 41 of the ahavi Makefile)
I really dont think the above has the desired effect!
