Ok, g++ fans, today I've just compiled libg++-1.40 and all the tests. But that
took a lot of time, especially because I had to fiddle around with the
sources.. But, alas, not everything worked - tMap failed, but only for
Skiptest, all the rest seems OK.
(hi Roland, thanks for your great lib!!)
0) Configure g++2.0 with using collect2 or link the old ld++ from 1.40 at the
proper place . The Makefile target 'install-collect2' makes it right. Thus you
use Sun's ld with dynamic linking !
1) Change the Makefile of libg++. I use 1.40. I beleive you MUST set
-DNO_GNULIB3 since __main is now in libgcc.a
2) Uncomment or remove all '#pragma once' in g++-include, g++-include/sys and
g++-include/gen like this for csh (sh : for i in ..... do ... od , I believe..)
foreach i (g++-include/* g++-include/sys/* g++-include/gen* )
sed 's/\#pragma once//' $i > temp
mv tmp $i
end
No, no patches - it's too simple and the patches would be endless...
3) There are indeed errors in GetOpt.cc, RNG.cc, gen/SkipSet.ccP,
gen/SkipMap.ccP and gen/SkipMap.ccP: 'Someone' forgot to initialize and define
some static member variables of these classes. I wonder if this ever worked
with cfront 2.0/2.1... Anyway, here a the patches:

And now hit 'make src' (should work now, I hope - on SunOS 4.1.1 it does).
It will spit out a lot of warnings due to conversion/assignments/comparisions
between signed and unsigned values and so on. Time: 20-30 min
And then 'make tests'. The best is to do that not on your machine since it
just took something around a full hour on my comrade's SLC (hah!)...
Well, and on a SPARC the final diff bails out since tMap has failed.
Splaytest is fine, Skiptest not so quite and then an assertion bites:
