There are two bootstrap tarballs that differ:
(1) static-binaries
(2) guile-static-stripped
In this message, I'll address only the 'static-binaries'.
The only difference in the static-binaries is bash. It turns out that
the bash-4.4 configure script produces an incorrect compile-time
configuration when built on Linux 5.x or later. It boils down to this
code in Bash's configure.ac:
--8<---------------cut here---------------start------------->8---
linux*) LOCAL_LDFLAGS=-rdynamic # allow dynamic loading
case "`uname -r`" in
2.[[456789]]*|[[34]]*) AC_DEFINE(PGRP_PIPE) ;;
esac ;;
--8<---------------cut here---------------end--------------->8---
In bash-5.0, this code has been changed to:
--8<---------------cut here---------------start------------->8---
linux*) LOCAL_LDFLAGS=-rdynamic # allow dynamic loading
case "`uname -r`" in
1.*|2.[[0123]]*) : ;;
*) AC_DEFINE(PGRP_PIPE) ;;
esac ;;
--8<---------------cut here---------------end--------------->8---
which is certainly an improvement, but still nondeterministic. We
should probably fix that.
Anyway, it appears that our static-binaries-0-i686-linux.tar.xz tarball
can only be built correctly on a machine running Linux 4.x or earlier.
Mark
