Hi G=
uix!

I have the attached file that build Scala, although it's notbootstrapped at all=2E It contains %binary-scala, a few 
dependencies o=
f
Scala we haven't packaged yet, and the final scala, built from
%bin=
ary-scala, without sbt (which requires Scala too)=2E

Since I've trie=
d and failed to bootstrap Scala for so long, I 
think
it's time to gi=
ve up=2E I can't always create miracles=2E

 Some points=
 relevant to bootstrapping:
 - The last version, that ships "scalai" wri=
tten in Java seems to 
 be 
   v1=2E4=2E0+4=2E  Perhaps one can use s=
calai to bootstrap scalac 
   within it=2E
 - The last version, that =
does not "require" sbt is 2=2E11=2Ex,
   though with your workaround we =
can also build later versions=2E

We tried building a cl=
ean bootstrap chain for Scala for years=2E 
Back then I went down the ra=
bbit hole and found that early scalac 
is written in Pizza; but it turne=
d out that Pizza is written in 
Pizza and is released under the old Arti=
stic License, which is 
considered non-free=2E

I pointed a branch at =
an old Scala commit that contains the old 
Socos compiler source, which =
ostensibly are written in Java, but 
actually are not:

    https://gi=

This is at arou=
nd version 1=2E4=2E0=2E4, as you wrote above=2E

Since the old days S=
cala Native has grown considerably, and 
perhaps we can reuse some of it=
s native libraries=2E  I=E2=80=99m not too 
hopeful, because the bulk of=
 it is still written in Scala, 
obviously, but there are parts that are =
written in C / C++, which 
might come in handy=2E
