-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Format: 1.8 Date: Fri, 11 Sep 2026 09:48:42 +0100 Binary: mit-scheme mit-scheme-dbg mit-scheme-dbgsym mit-scheme-doc mit-scheme-svm mit-scheme-svm-dbgsym Source: mit-scheme Architecture: all amd64 arm64 i386 ppc64el source Version: 12.1-6 Distribution: unstable Urgency: medium Maintainer: Barak A. Pearlmutter <[email protected]> Changed-By: Barak A. Pearlmutter <[email protected]> Closes: 365530 Description: mit-scheme-dbg - MIT/GNU Scheme debugging files mit-scheme-doc - MIT/GNU Scheme documentation mit-scheme - MIT/GNU Scheme development environment mit-scheme-svm - MIT/GNU Scheme development environment (portable SVM build) Changes: mit-scheme (12.1-6) unstable; urgency=medium . * Put developer-relevant info in debian/NOTES.md, leaving README.Debian for user-relevant info only. * New binary package mit-scheme-svm, which uses a virtual machine rather than a native back end. Co-installable with the native build; both Provides: mit-scheme-interpreter. Control with build profiles pkg.mit-scheme.nonative / pkg.mit-scheme.nosvm. A mapping from Debian architecture to upstream back-end names, used in build options and filenames, is in debian/rules. Which flavours can build on the current arch comes from dh_listpackages, which isolates that information to debian/control. (Note: scmutils, the only package depending on mit-scheme, installs native .com files into the native flavour's auxiliary directory, so it cannot use the -svm flavor.) Make AUXDIR_NAME overridable, so the flavours can have separate aux directories. Update mit-scheme alternative for multiple installed flavors, with preference for native. Mark the self-referential build dependency :native, and use $(DEB_HOST_MULTIARCH) rather than a hardcoded triplet. * Decide --enable-cross-compiling by checking which compiled-code format the build-time-available mit-scheme produces, rather than comparing versions; otherwise building the SVM flavour with a native Scheme fails with fasl-file-bad-data when saving lib/runtime.com. * Build for arm64, and, via the new SVM flavour, armhf, i386, and ppc64el (closes: #365530). Include ppc64el confshared.h patch. (Note: armhf has a machine type but does not define HEAP_IN_LOW_MEMORY, so it cannot load bands or FASL files built anywhere else, and therefore cannot be bootstrapped.) * Record what makes an SVM band portable across architectures in debian/NOTES.md. * Bootstrap from a prebuilt SVM library when present in debian/prebuilt/ and no mit-scheme is installed. (This can avoid the need to manually seed new architectures. See debian/NOTES.md and git branch debian-bootstrap. Note: debian/prebuilt/ not currently in source package because it's an enormous binary blob.) * Override old-fsf-address-in-copyright-file (the Cambridge postal address in debian/copyright is MIT's, which lintian mistakes for the FSF's old address.) * Install man page under the version-qualified name of real binary. * Record upstream bug tracker in debian/upstream/metadata. * Split dh_auto_* overrides into -arch and -indep, so architecture-only builds no longer build the documentation. Move texlive, texlive-plain-generic and ghostscript to Build-Depends-Indep: only doc/ uses TeX, and that is now built only in the -indep sequence. Keep texinfo because plugins under src/ run makeinfo.
