[SOLVED] Cannot convert 64bit module from lzm to xzm

Please reproduce your error on a second machine before posting, and check the error by running without saved changes or extra modules (See FAQ No. 13, "How to report a bug"). For unstable Porteus versions (alpha, beta, rc) please use the relevant thread in our "Development" section.

[SOLVED] Cannot convert 64bit module from lzm to xzm

Post#1 by att » 08 Apr 2011, 12:11

Hello,
I have a problem converting one lzm module to xzm. I always get an error from mksquashfs, saying "unable to create", or somesuch.
The module in question is "nzbperl_64bitaddon.lzm" from my own repository (which is on Usenet).
I have depacked the file from Slax-Remix v09 and made a TAR file :
http://ompldr.org/vODY2ZA/nzbperl64bitaddon.tar

If you can convert this to a normal xzm module (with main directory /usr to where it belongs) please let me know, and let me know how to do it.

Try these commands:

1.

Code: Select all

mkdir /tmp/wrk
2.

Code: Select all

lzm2dir /path/to/module.lzm /tmp/wrk
3.

Code: Select all

dir2xzm /tmp/wrk /tmp/mymodule.xzm

Pleeeaaase help, I discovered that "dir2xzm" has a bug!

I am still trying to make a module out of my directory in /tmp, which contains all the files necessary:

root@porteus:/tmp# cd
root@porteus:~# dir2xzm /tmp/lib64_nzbperl /tmp/mymod.xzm
mksquashfs: invalid option

Compress using filter1,filter2,...,filterN in turn
(in addition to no filter), and choose the best compression.
Available filters: x86, arm, armthumb, powerpc, sparc, ia64
-Xdict-size <dict-size>
Use <dict-size> as the XZ dictionary size. The dictionary size
can be specified as a percentage of the block size, or as an
absolute value. The dictionary size must be less than or equal
to the block size and 8192 bytes or larger. It must also be
storable in the xz header as either 2^n or as 2^n+2^(n+1).
Example dict-sizes are 75%, 50%, 37.5%, 25%, or 32K, 16K, 8K
etc.
error building compressed image
root@porteus:~#

So you see, I always get the error "mksquashfs: invalid option".
I get the same error when I use the Dolphin filemanager and right-click to make a module.

What do I do now?

Try with

Code: Select all

mksquashfs /tmp/lib64_nzbperl /tmp/mymod.xzm -b 256K

It is strange, I just discovered that if I call "mksquashfs" myself instead of create_module, then it seems to work: Look at this:

root@porteus:/tmp# mksquashfs lib64_nzbperl test1.xzm
Parallel mksquashfs: Using 2 processors
Creating 4.0 filesystem on test1.xzm, block size 131072.

duplicates are removed
Filesystem size 875.54 Kbytes (0.86 Mbytes)
24.30% of uncompressed filesystem size (3602.89 Kbytes)
Inode table size 3180 bytes (3.11 Kbytes)
25.69% of uncompressed inode table size (12376 bytes)
Directory table size 3072 bytes (3.00 Kbytes)
37.35% of uncompressed directory table size (8224 bytes)
Number of duplicate files found 15
Number of inodes 385
Number of files 311
Number of fragments 18
Number of symbolic links 0
Number of device nodes 0
Number of fifo nodes 0
Number of socket nodes 0
Number of directories 74
Number of ids (unique uids + gids) 1
Number of uids 1
root (0)
Number of gids 1
root (0)

-------> seems to work, doesn't it ?

Now the same with Create_module, from the script :

root@porteus:/tmp# create_module lib64_nzbperl ttt.xzm

I also cannot find the file for "create_module" or "liblinuxlive", which is weird. Any suggestions ?

Please don't change anything in liblinuxlive , because , if you change a "vital" thing in it , you can crash your system , and you can loose your data.

You can use a shell script

Code: Select all

#!/bin/bash

x=$1 
y=$2

mksquashfs $x $y -b 256K

Save this code in text file , and make it executable (chmod +x) , after just execute it

root@porteus:~# ./make_module /tmp/lib64_nzbperl /tmp/test1.xzm

@att
no matter how hard i try, dir2xzm always work.
did you modify /usr/lib/liblinuxlive?
this is a 'tar' archive (not tgz)
http://ompldr.org/vODY2ZA/nzbperl64bitaddon.tar
so unpack it first and then use dir2xzm

@Hamza
mksquashfs $1 $2 -b 256K
will work as well :)
Please add [Solved] to your thread title if the solution was found.

Well, I have no idea what is wrong with my liblinuxlive, but I will investigate.
In the meantime, using "mksquashfs" seems to fix these issues. Thanks for the advice!
