[ptxdist] OSELAS.toolchain - GCC snapshots gone

[ptxdist] OSELAS.toolchain - GCC snapshots gone

[Ariel Garcia]

Hello,

trying to reproduce a somewhat older setup using OSELAS 2019.09.1
I noticed that it fails due to:

-----
Could not download package
URL: https://ftp.gnu.org/gnu/gcc/gcc-9-20191130/gcc-9-20191130.tar.xz http://
ftp.uni-kl.de/pub/gnu/gcc/gcc-9-20191130/gcc-9-20191130.tar.xz https://

GNU seems to have cleaned up, and mirrors followed. Also the copy in
	https://www.pengutronix.de/software/ptxdist/temporary-src/
is gone.

Shouldn't OSELAS always use real releases (GCC and other) instead of (daily?) 
snapshots?


I can't "just update" to a newer OSELAS version, since i rely on reproducible 
builds for performing incremental updates. A change in the compiler would 
imply that all binaries would change...

Any suggestion on how to rely on OSELAS / PTXdist versions to remain 
"buildable" in the future?

Also, any hint on where to find the old snapshot?
(trying "git archive" from the GCC repo and different commits in the 
releases/gcc-9 branch, but i was unable to find the same md5 sum given by 
OSELAS 2019.09.1)

Thanks a lot,
Ariel

As a quick fix, I've put the copy from our local source archive on the
temporary-src mirror for now. Try again.

I think gcc-9-20191130 included some fixes to make it build on certain
platforms, so Michael picked that version.

In the old days I packed once built toolchains to tarballs and put it
aside and in my backup.  Nowadays I use the pre built debian packages
from http://debian.pengutronix.de/ – maybe that's an option for you,
too?

Although I keep my src archive in a central place covered by backup, I
doubt I have stuff for oselas toolchain 2019.09.x in there.  I can not
remember having used it at all.  Otherwise I could have given you a
copy for your own archive or mirror.
