All versions of cloop fail in a system with gentoo-sources 2.6.24-gentoo-r4.
Here are my top-most build errors when trying to emerge cloop-2.04:

I believe cloop should be masked for current kernel versions. I'm surprised that I don't see any recent posts or bugs regarding this. Am I the only person that has any interest in using this driver?
My solution was to create a portage overlay folder and a sys-fs/cloop-2.06, with the current cloop sources. Here is the contents of my ebuild, /usr/local/portage/sys-fs/cloop/cloop-2.06.ebuild:

This seems to work. I'm new to writing ebuilds, so I've probably violated a few rules in creating this one.
To us this, create a portage overlay as described in the Overlay guide:
http://www.gentoo.org/proj/en/overlays/userguide.xml
Copy the contents of the code above into the following file:
/usr/local/portage/sys-fs/cloop/cloop-2.06.ebuild
(assuming that your portage overlay directory is located at /usr/local/portage)
Unmask the newly-created ebuild:
# echo "=sys-fs/cloop-2.06 ~x86" >> /etc/portage/package.keywords
Emerge the package:
# emerge cloop -av
Load the module:
# modprobe cloop
Mount a compressed filesystem:
(untested at the moment)
Note: there seems to be a slight problem with unmerging; cloop.ko is not removed from /lib/modules/2.6.24-r4

Wasn't sys-fs/cloop-2.624 already added to the tree back in March? Namely, in bug 207998?
Edit: I seem to have /usr/portage/sys-fs/cloop/cloop-2.624.ebuild from March 11, has line
| Code: | | # $Header: /var/cvsroot/gentoo-x86/sys-fs/cloop/cloop-2.624.ebuild,v 1.1 2008/03/11 20:24:29 genstef Exp $ |
in it, but the Changelog is from November 2007... |

Thanks. It seems that I forgot to add an eix-update cron job, so my eix package database was out-of-date, and not reporting the new(masked) version of cloop. How embarrassing!  I thought I'd looked at the list of ebuilds directly, but I guess not. |

| Well, it doesn't appear on p.g.o and is not mentioned in the Changelog, so it is rather easy to overlook... |

Hi,
For linux-2.6.25-gentoo-r7 kernel cloop 2.624 give this error.

Is there already a solution ? |

Yes, it does seem broken again, but that seems to be because the 2.625 version has not yet been added to portage. CLoop version 2.624 is not compatible with 2.6.25 kernels. See:
http://archive.netbsd.se/?ml=debian-knoppix&a=2008-04&t=7230429
Note: At the bottom of that URL, Klaus Knopper offers an updated updated compressed_loop.c. I verified that I could replace my original file and cloop would compile. However, Dr. Knopper also offered a warning on that page:
| Quote: | | So, please wait for an official release before using cloop 2.625 for a cloop-based distribution... |
So, I did not attempt to use it.
I then discovered that cloop version 2.625 has been available on debian.org since 22 Sept 2008. That's where the Portage fetches the sources from (the SRC_URI).
The 2.625 overlay is remarkably-simple to create:
1) if you don't already have an Portage overlay, follow the steps on this page:
http://upir.cz/linux/portage-overlay-howto.html
(random page on the Portage overlay topic; a gentoo.org link would probably be preferred)
2) Assuming that your overlay is located at /usr/local/portage:
| Code: | # cd /usr/local/portage/
# mkdir -p sys-fs/cloop
# cd sys-fs/cloop/
# cp -a /usr/portage/sys-fs/cloop/cloop-2.624.ebuild ./cloop-2.625.ebuild
# ebuild cloop-2.625.ebuild digest
# echo "=sys-fs/cloop-2.625 ~x86" >> /etc/portage/package.keywords
# emerge cloop -av
# modprobe cloop
|
Note: this does not require any editing of the ebuild file. The act of changing the filename (and perhaps running the ebuild ... digest command) causes the proper file to be downloaded.
Disclaimer: I have built and installed the cloop module, but have not yet tested it yet. |

Hi,
What about sys-block/gcloop ?
cloop is Masked in portage and last release of gcloop is from 2004 !!!
