hi,
I'm useing gentoo on kernel 3.2.1-gentoo-r2 and want to install loop-aes but got the following error.

Code:

emerge sys-fs/loop-aes

* IMPORTANT: 3 news items need reading for repository 'gentoo'.

* Last emerge --sync was 11d 1h 11m 27s ago.

it seems that there is a problem with my kernel version...
loop-eas also created broken symlink named patched-loop.c to ../loop.c-3.2.patched file in /var/tmp/portage/sys-fs/loop-aes-3.6b/work/loop-AES-v3.6b/tmp-d-kbuild/. I don't konw why loop.c-3.2.patched file is missing!
any help/idea will be appreciated.

Why do you want to install loop-aes? There are better alternatives for new installations. According to the ChangeLog of sys-fs/loop-aes, you need a newer version to compile with a 3.2 kernel.

I had a similar problem (see http://forums.gentoo.org/viewtopic-t-911100-highlight-loopaes.html) I ended up going with 3.6e.

.

loop-aes is faster than Cryptoloop. but Loop-AES explicitly prohibits use of journaling filesystem and looking for good alternative !

TNX, using 3.6e version fixed my problem ..

That's not quite true. You can't use a journaling filesystem on top of a file backed loop device, but you can with a device backed loop device. See section 2.2 of the README:

Code:

Don't use a journaling file system on top of file backed loop device. Device
backed loop device can be used with journaling file systems...
