Re: [Tack-devel] Prime Mover commands

[tim k. <gt...@di...>]

Hi,
I have some additional questions about Prime Mover, as I am using it to be
the build tool for the bootloader I've been modifying for the last couple
of years.

1) With targets that are included via including their pmfiles, are the
globals in the master pmfile evaluated?  I define ROOTDIR in the master
pmfile but when I try to build an included target, ROOTDIR is a nil pointer:

> ./pm -v libsa
./.pm-exec-macppc: lib/libsa/pmfile:5: attempt to concatenate global
`ROOTDIR' (a nil value)
stack traceback:
        lib/libsa/pmfile:5: in function `c'
        stdin:937: in function `include'
        pmfile:5: in function `c'
        stdin:1524: in main chunk
        [C]: ?

line 5 in lib/libsa/pmfile:

local d = ROOTDIR.."lib/libsa/"


2) Is there a flag that is the equivalent of -V in make to display the
value of a variable?  If there is not, I would like to make a feature
request to expand the -D flag, such that -D?X lists the first iterative
evaluation of X and -D??X lists the completely iterated evaluation of X.
For example,

-D?d in the above would yield ROOTDIR/lib/libsa and -D??d would fill in
ROOTDIR (including any included variables in ROOTDIR).


3)  As another feature request, can the cache directory no longer default
to a "." directory?  Sometimes I forget the cache directory is hidden, and
while at least with OpenBSD "ls" does automatically -a, not all systems do.


4) Can I get some bare-bones description on differences between cfiles,
cprograms, clibraries, and other possible options?  While much of these
objects is self-explanatory or available through reading the code, it would
be of use to me to have something I can refer to and/or analyze for
locations to do inheritence of those objects to more localized versions
with optimizations included.

thanks in advance,
tim
