Well, this is embarrassing... I just realized that my chroot had a copy of qemu-arm-static in it from before I upgraded to bionic and that binfmt_misc uses that copy instead of the host system copy. I wiped out the chroot and rebuilt it so that the new qemu-arm-static from bionic is included in the chroot.

I managed to get it to build: ./configure --static --enable-debug --target-list=arm-linux-user Then, I ran my pbuilder script again. It hung in cmake as usual.

It will need all the dev libs I assume. Maybe just this: $ sudo apt build-dep qemu Also the configure by default enables "too much", from the last build for static that is in Ubuntu: ../configure --with-pkgversion="Debian 1:2.11+dfsg-1ubuntu6" --extra-cflags="-g -O2 -fdebug-prefix-map=/<>/qemu-2.11+dfsg=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -DCONFIG_QEMU_DATAPATH='\"/usr/share/qemu:/usr/share/seabios:/usr/lib/ipxe/qemu\"' -DVENDOR_UBUNTU" --extra-ldflags="-Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,--as-needed" --prefix=/usr --sysconfdir=/etc --libdir=/usr/lib/x86_64-linux-gnu --libexecdir=/usr/lib/qemu --localstatedir=/var --disable-blobs --disable-strip --interp-prefix=/etc/qemu-binfmt/%M --localstatedir=/var --static --disable-system --target-list="i386-linux-user x86_64-linux-user alpha-linux-user aarch64-linux-user arm-linux-user armeb-linux-user cris-linux-user hppa-linux-user m68k-linux-user microblaze-linux-user microblazeel-linux-user mips-linux-user mipsel-linux-user mips64-linux-user mips64el-linux-user mipsn32-linux-user mipsn32el-linux-user nios2-linux-user or1k-linux-user ppc-linux-user ppc64-linux-user ppc64abi32-linux-user ppc64le-linux-user sh4-linux-user sh4eb-linux-user sparc-linux-user sparc64-linux-user sparc32plus-linux-user s390x-linux-user tilegx-linux-user" Obviously you can strip targets and dirs for your case, so maybe the following after having the full build deps? ../configure --extra-cflags="-g -O2 -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -DCONFIG_QEMU_DATAPATH='\"/usr/share/qemu:/usr/share/seabios:/usr/lib/ipxe/qemu\"' --extra-ldflags="-Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,--as-needed" --prefix=/usr --sysconfdir=/etc --libdir=/usr/lib/x86_64-linux-gnu --libexecdir=/usr/lib/qemu --localstatedir=/var --disable-blobs --disable-strip --interp-prefix=/etc/qemu-binfmt/%M --localstatedir=/var --static --disable-system --target-list="aarch64-linux-user arm-linux-user armeb-linux-user" Feel free to look through [1] for more.

The repro fails complaining about an invlaid treeish even thou it is in the repo you mentioned. # OS=debian ARCH=armhf DIST=stretch pbuilder-ev3dev dev-build gbp:info: Building with pbuilder for stretch:armhf gbp:error: upstream/3.2.0+dfsg is not a valid treeish I was trying to run that on qemu 2.11.1 and 2.12 as I'm pretty sure - just like the older bug - this is an upstream and not an Ubuntu specific issue. But without being able to verify that I can't yet reasonably add the upstream qemu task.
