This did not work for me, unfortunately.

./.pm-exec-macppc: stdin:71: Attempt to write to new global intermediatecache
stack traceback:
        [C]: in function `error'
        stdin:71: in function <stdin:70>
        lib/libsa/pmfile:12: in function `c'
        stdin:937: in function `include'
        pmfile:16: in function `c'
        stdin:1524: in main chunk
        [C]: ?


The local pmfile:

local o = OBJDIR.."lib/libsa/"

pm.intermediatecache = o



On a different note, I would like to alter the default cfile behavior
slightly, but I am having some difficulty achieving my desired results.  I
wish to simplify the adding of files to pmfiles, such that I add a single
line naming the root of the .c file and both the source .c file and the
output .o file are created dynamically.  For example:

qdvirem = ext_cfile {"qdivrem"}

should know to look in the source code directory for qdivrem.c and to
output to the object directory qdivrem.o.  With the above syntax I can then
add qdivrem to a group while compiling it individually if I choose.

math = group {
            stuff,
            qdvirem,
            more_stuff,
}


I have been able to achieve basic results by overriding the cfile outputs
method at the time of the declaration of qdvirem:


qdvirem = cfile {d.."qdivrem.c"}, output = {o.."qdvirem.o"} }

but this is still unnecessarily verbose.  My attempts to override the
inputs to cfile are not succeeding:

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

local o = OBJDIR.."lib/libsa/"

ext_cfile = cfile {
        class = "ext_cfile",
        outputs = {o.."%in%.o"},
        in = {d..%in%..".c"},
}

I have also attempted to modify the definition of cfile in c.pm, but I am
not getting anywhere there, either, as there is still the intermediate
cache location as the default.  I don't grok where U and I are defined,
also.

Any suggestions/advice are greatly appreciated (I did manage to get a shell
file executing to build the versioning information for the executable, a
small victory to cling to).

thanks in advance,
