Examples (6) from the manual page, untested
CC=i386-gnu-gcc dpkg-architecture -c debian/rules build
dpkg-buildpackage accepts the -a option and passes it to dpkg-architecture.dpkg-architecture -elinux-arm64
Check if the current or specified host architecture is equal to an architecture:dpkg-architecture -ilinux-any
Check if the current or specified host architecture is a Linux system:DEB_BUILD_GNU_TYPE ?= $(shell dpkg-architecture -qDEB_BUILD_GNU_TYPE)
Retrieving the GNU system type and forwarding it to ./configure:DEB_HOST_ARCH ?= $(shell dpkg-architecture -qDEB_HOST_ARCH)
Doing something only for a specific architecture:include /usr/share/dpkg/architecture.mk
Note that you can also rely on an external Makefile snippet to properly set all the variables that dpkg-architecture can provide:
