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

[att]

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.

[Hamza]

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

@att
try 'lzm2xzm' cli utility - works always for me.
add [SOLVED] if solved.

try 'lzm2xzm' cli utility - works always for me.

@fanthom , I forgotten this script.

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

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?

[Hamza]

Try with

Code: Select all

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

[att]

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

-------> 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 ?

[Hamza]

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

[fanthom]

@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

[att]

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!
