[M3devel] Still can't bootstrap cm3

[Rodney M. Bates]

We still have serious problems with the cm3 system building.
I have again gotten into a big hampster wheel of several different
failures, and still can't rebuild a working compiler.
I have gone through enough steps that I am not just positive
I have remembered it all right, but it was something like this:

I started with ./do-cm3-front.sh, ./do-cm3-front.sh -ship, and
./install-cm3-compiler.sh upgrade.  That left me with a compiler
that always failed with:

Then I tried rebuilding using various do-cm3-* scripts, including after
supplying argument realclean (which, I have learned many times in the
past, is essential to avoid all sorts of problems), with the same results.
Somewhere in here, I started getting the bad version stamp failures too.
Eventually, trying to rebootstrap with ./upgrade.sh, and also manually,
a package at a time, I was consistently getting:

Perhaps it was the realclean that deleted all the .M3EXPORTS files.
../boot_cm3-core.sh LINUXLIBC6 gave this failure:

new source -> compiling RTHooks.i3

/home/rodney/proj/m3/cm3-new/cm3/m3-sys/m3cc/LINUXLIBC6-LINUXLIBC6/cm3cg: not found
   m3_backend => 127
m3cc (aka cm3cg) failed compiling: RTHooks.ic

---------------------------------------------------------------------------------------------------------

Fortunately, an earlier ./upgrade.sh had built a cm3cg (though it had failed
on all the Modula-3 code).  I got around the above by putting in a symbolic
link from cm3/m3-sys/m3cc/LINUXLIBC6-LINUXLIBC6 to cm3/m3-sys/m3cc/LINUXLIBC6,
so it could find cm3cg.

Then I went through the package-at-a-time order Tony had given in an old post
to the m3devel list.  That had other problems.  Running cm3 in the package
directory failed with the undefined ROOT problem, but do-pkg.sh would do the
build.  But do-pkg.sh doesn't appear to do a ship, so I had to do that in
each package with cm3 -ship.

After building and shipping m3 middle and m3front, package cm3 itself wouldn't
link, wanting libraries for m3back, m3objfile, m3quake, sysutils, m3linker, libm3,
and m3core.  I skipped it and m3gc*, which don't exist now, and went through the
rest of the order, which completed without failures building.  But that gave
me a compiler that fails with a new problem I have never seen before:

------------------------------------------------------------------------------------------------------------

Going back to an older cm3 makes that go away and makes the ROOT problem
recur.  Working around that with cm3 -DROOT="/home/rodney/proj/m3/cm3-new/cm3"
get the compiler to run, but it doesn't do anything, because it thinks
nothing needs to be recompiled.  I could delete stuff, but I fear that would
just start me around another iteration of the same thing.

I don't believe I have ever gotten a bootstrap to work.  I think I have always
had to download a recent binary and go from there.

Any help would be greatly appreciated.
