I compiled bzip2 as linux from scratch's book. I can run it in my original linux environment (by running /root/LFS/bin/bzip2). But when I chroot into /root/LFS, I can't execute bzip2 anymore. ( error is : bash: ./bzip2: No such file or directory). Other executables, such as tar, cat are working perfectly under chroot and outside chroot.

Anyone has experienced this? What should I check?
