Source: architecture-properties
Section: devel
Priority: optional
Maintainer: Architecture Properties Maintainers <architecture-properties@packages.debian.org>
Uploaders: Niels Thykier <niels@thykier.net>,
Build-Depends: debhelper-compat (= 13), perl:any
Rules-Requires-Root: no
Standards-Version: 4.6.1
Vcs-Git: https://salsa.debian.org/debian/architecture-properties.git
Vcs-Browser: https://salsa.debian.org/debian/architecture-properties
Package: architecture-properties
Architecture: any
Multi-Arch: same
Provides: architecture-is-${DEB-HOST-ARCH-BITS}-bit,
architecture-is-${DEB-HOST-ARCH-ENDIAN}-endian
Description: Declarative architecture constraints
This is a meta package that provide declarative architecture
constraints like "architecture-is-64-bit" or
"architecture-is-little-endian" for cases where architecture
wildcard support in the Architecture field is insufficient.
.
Example usage: "Build-Depends: architecture-is-64-bit".
.
This package is provided solely for the purpose of being used
in build-dependencies to simplify management of architecture
support.
Package: native-architecture
Architecture: all
Multi-Arch: no
# Due to being M-A:no, this package can only ever satisfy native architecture
# dependencies and that quite precisely is its purpose. Its Multi-Arch value
# must not change even if the hinter says so.
Description: Declarative native architecture constraint
This is a meta package that can only satisfy a dependency for the
native architecture. The native architecture is defined as the
architecture of the dpkg package by the Multi-Arch specification. By
depending on native-architecture, a client package can prevent its
installation for a non-native architecture.
Package: native-architecture-is
Architecture: any
Multi-Arch: foreign
Depends: native-architecture
Provides: native-architecture-is-${DEB-HOST-ARCH}
# Due to the dependency on native-architecture, this package can only ever be
# installed for the native architecture. The native instance of this package
# can always be installed. A dependency on native-architecture-is is thus
# always satisfiable and thereby meaningless. The benefit of this package
# arises from its Provides where the architecture constraint is lifted into the
# package name.
Description: Declarative native architecture assertions
This is a meta package that can be used to assert that a particular
architecture is native. The native architecture is defined as the
architecture of the dpkg package by the Multi-Arch specification. By
depending on e.g. native-architecture-is-amd64, a client package can
prevent its installation unless the native architecture is amd64.
Package: cross-exe-wrapper
Architecture: any
Multi-Arch: same
Depends:
${shlibs:Depends},
native-architecture | native-architecture-is-amd64 [i386] | native-architecture-is-x32 [i386] | native-architecture-is-armhf [armel] | native-architecture-is-mips64el [mipsel] | native-architecture-is-ppc64 [powerpc] | native-architecture-is-sparc64 [sparc] | qemu-user | qemu-user-static,
# The dependency ensures that either the architecture we use for installing is
# the native architecture or the native architecture is sibling architecture of
# the package architecture that is known to reliably run its code or a qemu is
# installed. For instance, native-architecture-is-arm64 [armhf] is missing as
# some recent arm64 CPUs no longer run 32bit code. The alternatives also ensure
# that e.g. no qemu is required for installing cross-exe-wrapper:i386 on amd64
# as we can reliably run i386 executables there without emulation.
Description: Wrapper for executing binaries from other architectures
Provides a tool ${DEB_HOST_GNU_TYPE}-cross-exe-wrapper that can be
used to run ${DEB_HOST_ARCH} ELF executables on the current CPU
employing emulation technology if required.
.
Since the tools are named per architecture, they should generally
always be referred to via the substituion variable as done above.
