module-assistant does not compile squashfs-source

[Andreas Krüger]

Binary package hint: squashfs-source

Hello,

here is the output of "lsb_release -rd"
Description: Ubuntu 9.04
Release: 9.04

Here is some of the output of "dpkg -s squashfs-source"

Package: squashfs-source
Source: squashfs
Version: 1:3.3-7ubuntu2

and here some of "dpkg -s module-assistant":

Package: module-assistant
Version: 0.10.11ubuntu1

And here is the build log, generated by "LANG=C module-assistant build squashfs-source" :

Of course, I expected this build to come through. As you can see from the build log, it failed instead.

As far as I can tell, this is independent from the problems reported as bug 17689.

Regards, and thank you for providing fine software,

Andreas

Oops - independent of bug 176890 , I meant to write. Sorry about the missing "0" in the original bug description.

http://xhochy.org/en/2009/06/20/compling-squashfs-source-on-ubuntu-jaunty/ explains how to fix this problem, this is already fixed in Squashfs 3.4

[Andreas Krüger (andreas-krueger)]

Thanks, Uwe! The hints given at the URL you provided indeed helped me out.

Here are the details:

Upgrade to linux-headers-2.6.28-13-generic and linux-headers-2.6.28-13. Bug still present.

The module lzma mentioned in the above link is not available through my Ubuntu 9.04's module-assistant GUI.
Even after installation of lzma-source, the module-assistant GUI does not show it.
However, simply firing up "m-a build lzma" produces a .deb allright, which "dpkg -i" could install.
Afterwards, "modprobe -v sqlzma" worked. So far, so good.

Quick check: With lzma installed and module sqlzma loaded, squashfs still does not build. That was to be expected.

I used emacs to edit inode.c in the archive directly (didn't bother to unpack and repack).
After those changes, "m-a build squashfs" ran through with no problem.
Also smooth sailing for "m-a install squashfs" , and finally, for "modprobe squashfs".

Finally, mounting a squash file system and reading all files also worked.
