To build the imp compiler from source, fully bootstrapped so that it is compiled by itself,
issue this command *IN AN EMPTY DIRECTORY*:

  wget https://gtoal.com/imp77-in-C/Release0.2/MAKE-ALL.sh ; sh < MAKE-ALL.sh |& tee MAKE.LOG

Having a GCC compiler is a hard requirement.  If you don't have gcc installed, either install
it or use the alternative bootstrap method at https://github.com/siliconsam/imp2021 which
relies on previously compiled binaries.

This should build on most linux systems without error.  Some systems however haven't been tested,
so if you get a lot of errors when running the script, send me (gtoal@gtoal.com) the MAKE.LOG file
to debug.  Imp may also build on BSD systems or Mac O/S, but those systems are essentially untested.


Now, even if it all the binaries managed to build, we still have some slight discrepancies
between the binaries generated by the C port of the compiler and the original Imp code.
We're working on those and should have them fixed soon, but in the mean time, if any files
failed the consistency check (ie the two binaries differed), then the problematic will be left
for inspection, but everything else that looked good will have been removed.

So, for example, "impcore-fext" and "implib-read" still had problems in this build:

gtoal@linux:~/src/imp77/hacks/new-boot$ ls
impcore-fexp2.lis    impcore-fexp-c.o     impcore-fexp-i.ibj  implib-read2.lis    implib-read-c.o     implib-read-i.ibj  libimp77.a  pass2     takeon
impcore-fexp-c2.lis  impcore-fexp-i2.lis  impcore-fexp-i.o    implib-read-c2.lis  implib-read-i2.lis  implib-read-i.o    MAKE.LOG    pass3elf
impcore-fexp-c.ibj   impcore-fexp.ibj     impcore-fexp.o      implib-read-c.ibj   implib-read.ibj     implib-read.o      pass1       src


but if you run this after we sort the problems, you should just see the binaries, like this:

gtoal@linux:~/src/imp77/hacks/new-boot$ ls
libimp77.a  MAKE.LOG  pass1  pass2  pass3elf  src  takeon

The files used in building the compiler are in the src/ subdirectory and can be removed with rm -rf src

You can now follow John McMullin's instructions on where and how to install the binaries and
fetch any command scripts needed to use the compiler.  (We may add those to this script later,
but for now the only objective was to compile and bootstrap the compiler binaries themselves)

PS Building Imp with this script takes 30 seconds on my system, including the time to fetch
all the files!
