scheme and lisp

[Bernhard M. Wiedemann via rb-general]

Hi,




e.g. for scheme48 I extracted this reproducer:

pushd ~/rpmbuild/BUILD/scheme48-*/ps-compiler
    ../go -h 20000000 -a batch <<- 'EOF'
        ,config ,load ../scheme/prescheme/interface.scm
        ,config ,load ../scheme/prescheme/package-defs.scm
        ,exec ,load load-ps-compiler.scm
        ,in prescheme-compiler prescheme-compiler
        ,user (define prescheme-compiler ##)
        ,dump ../ps-compiler.image "(Pre-Scheme)"
        ,exit
EOF



The list of our packages I think are affected by this is:
clisp
scheme48
chezscheme
emacs
maxima
scsh
xindy

Most distros seem to be affected by this:
http://ismypackagereproducibleyet.org/?pkg=scheme48

in openSUSE there are some packages that so far refuse to build reproducibly. The common theme around them is that they use scheme or lisp to produce binaries with a 'dump' command. I also know that guile implements scheme and builds reproducibly (with -j1). So there must be a way to do it right. http://ismypackagereproducibleyet.org/?pkg=emacs surprisingly shows as reproducible in Archlinux, but I could not figure out why.

maxima also shows as green there.



I'd appreciate some insight from this knowledgeable crowd.

Ciao

Can we get them reproducible? Or can we drop+replace these implementations with guile?
