Dear Peter. Thank you for the update. Please find the attached full chroot environment that I used(scratch.armv7l.0.tar.gz, split three parts). You could try make build with below steps; $ sudo su $ echo -1 > /proc/sys/fs/binfmt_misc/arm $ echo ':arm:M::\x7fELF\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x28\x00:\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff\xff\xff\xff\xff\xfa\xff\xff\xff:/usr/bin/qemu-arm-static:' > /proc/sys/fs/binfmt_misc/register $ cat scratch.armv7l.0.tar.gz.a* > scratch.armv7l.0.tar.gz; sudo tar -zxf scratch.armv7l.0.tar.gz $ cd scratch.armv7l.0 $ chroot . chroot> cd /home/abuild/rpmbuild/BUILD/org.tizen.browser-1.6.2/build-tizen/services/ chroot> while :; do make clean; make -j32; done Reproducibility is ver low but it surely happened. Thanks.
