squashfs + lzma?

Asked by Johannes Schauer Marin Rodrigues

hi!
i wanted to ask a question about the packes squashfs-source and lzma-source.
squashfs-source depends on lzma-dev so i assume that it includes the patches from squashfs-lzma.org ?
and lzma-source is the kernel module required for squashfs with lzma support to work?
i installed both and saw the tar.bz2 archives in the /usr/src directory which i both unpacked. unfortunately there is no ./configure but only a Makefile - what do i do with the sourcecode? how do i happen to use squashfs with lzma with these packes? what are these packages for and how are they used?
cheers

the solution is to run
m-a build squashfs and lzma and install the resulting deb packages - this will enable squashfs lzma support in your kernel

just to make this dead-simple to follow:

# install source of squashfs and lzma kernel modules
sudo apt-get install squashfs-source lzma-source
# build the modules - this produces two .deb files in /usr/src
sudo m-a build lzma
sudo m-a build squashfs
# install these .deb files
sudo dpkg -i /usr/src/lzma-modules-*
sudo dpkg -i /usr/src/squashfs-modules-*
# load the module
sudo modprobe squashfs
# check if the module is loaded with:
lsmod | grep squashfs

I try d this, but while building squashfs I get this: Build of the package squashfs-source failed!

/usr/src/modules/squashfs/inode.c:693: error: implicit declaration of function 'd_alloc_anon'

To fix it take a look at:
