Re: Bootstrapping GT.M
Hi,
I'm just forewarding the answer of upstream about the possibilities
for the bootstrapping process ...
Any comments?
Kind regards
Andreas.

Sorry for the delayed reply, but I was caught up with some urgent work.
The way we bootstrap GT.M is that we use the previous release of GT.M to build
it. If you like, we are happy to provide you with the files from our build of
GT.M V5.3-001 (the current version), which will let you build it for yourself.
Alternatively, you can use the released binaries to build your own fresh
binaries from the released sources. But, just as there must be a C compiler to
build gcc, GT.M needs a MUMPS implementation - GT.M itself since there is no
alternative - to build GT.M. I don't see an easy way out of this conundrum.
There is of course no technical obstacle to replacing the bootstrap with awk or
perl programs, but that would be more work for us with no clear benefit.
In any case, it looks like there is precedent in the Debian world for
bootstrapping by requiring an existing binary for building a new binary.

What about providing the generated files in the initial upload? The
files can them be used to bootstrap the system on the autobuilders.
The initial upload can't build-depend on itself, but when it is built,
the next upload can build-depend on the previous version of itself.
Gcc compiles itself several times during bootstrapping, first a
minimal version that can use almost any C compiler, then itself with
the minimal version, and finally itself with the full version of
itself. Perhaps something similar should be done with GT.M? I
realize that the situation is different as there is no M compiler
included by default in Debian.
Happy hacking,
