Hi, On my x86_64 GuixSD machine, using Guix commit 77f921587c6b784e84b98a9f2e9c821f73114340, GNU Hello fails to build for the armhf-linux target. It builds for the i686-linux, aarch64-linux, and mip64el-linux targets. I'm trying to build it using the following command, invoked from the Guix source tree: ./pre-inst-env guix build --no-substitutes --target=armhf-linux hello Here are the last few lines of output: --8<---------------cut here---------------start------------->8--- starting phase `configure' source directory: "/tmp/guix-build-binutils-cross-armhf-linux-2.28.drv-0/binutils-2.28" (relative from build: ".") build directory: "/tmp/guix-build-binutils-cross-armhf-linux-2.28.drv-0/binutils-2.28" configure flags: ("CONFIG_SHELL=/gnu/store/kpxi8h3669afr9r1bgvaf9ij3y4wdyyn-bash-minimal-4.4.12/bin/bash" "SHELL=/gnu/store/kpxi8h3669afr9r1bgvaf9ij3y4wdyyn-bash-minimal-4.4.12/bin/bash" "--prefix=/gnu/store/gaap2chgcwkhk6z0vp4z47cy6rsxds1q-binutils-cross-armhf-linux-2.28" "--enable-fast-install" "--build=x86_64-unknown-linux-gnu" "--target=armhf-linux" "--with-sysroot=/" "LDFLAGS=-static-libgcc" "--with-lib-path=/no-ld-lib-path" "--enable-install-libbfd" "--enable-deterministic-archives") checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type...

However, "armhf-linux" is listed as a supported platform in the Guix manual ((guix) GNU Distribution), so I expected this to work. What's going on here? GNU Hello successfully builds on my machine for the x86_64-linux, i686-linux, aarch64-linux, and mips64el-linux platforms (i.e., all of the other platforms listed as supported in the Guix manual). -- Chris
