Do I need to any > other configuration? You need kernel .config that matches your running kernel exactly (like Jan-Benedict Glaw said earlier). And kernel source tree must be in fully compiled form, as in after: make distclean cp /someplace/yourconfig-2.4.18.config .config make oldconfig make dep && make clean && make bzImage && make modules And then compile loop-AES like this: cd ../loop-AES-v1.7b make LINUX_SOURCE=/path/to/your/kernel/source Just running "make oldconfig && make dep" is NOT enough. I have tried that. Got burned. Trust me on this one. Regards, Jari Ruusu <jari.ruusu@pp.inet.fi> - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
