SquashFS and V8/Z6

[s5vi]

Very good job....
You can try to compile squashfs-tools 3.2 with the same way.
It contains unsquasfs.
And pick mksquashfs.exe from 2.1 and unsquasfs.exe from 3.2

That was the idea, but the "newer" squashfs-tools need some more files (e.g. sysctl.h and ioctl.h) which is not in my cygwin and copying them from any Linux distro does not quite work.
Anyway I will use cygwin to install this and see what happens.

I have managed to have 4 skins in the "My Files" location, which means you can have easy access to them via Windows Explorer. So only problem now is the iconres.ezx of the V8 which still can not be opened and repackt.
More info here

Update: I have added a new folder in which I have linked the startup-/shutdown animation and sounds, so these can now be edited also via Windows Explorer.

Hello, everybody!
I'm interested in SquashFS tools for Windows too.
I'm developing EZXCodec program (can be downloaded from russian forum.motofan.ru, direct link to attachment with current version - http://forum.motofan.ru/index.php?act=Attach&type=post&id=144644 (program is multi-language and contains english docs))
So far for CramFS support I used Win32 builds of mkcramfs and cramfsck.
Now users want Z6/V8 support too (SquashFS).

Future plans are:
- add support for SquashFS;
- add support for JFFS (E6 and A1200 using it along with CramFS);
- get rid of cli external apps and build FS' support inside my exe...

Can you open a V8 iconres.ezx file and repack it again?
It is possible with the Z6 iconres.ezx, but not with V8 iconres.ezx. And that is at the moment the last hurdle that stops V8 skinners.
PS. the link you gave is not working -> "Problem loading page" message

I can download, copied here:

Found compiled mksquashfs 2.1 for Windows here
Still looking for unsquashfs...
btw next version of EZXCodec will be able to compile/decompile iconres.ezx (using info from that file)
no support for pictures format used in Z6/V8 though...

squashfs-tools indeed can be compiled for Cygwin (after some modifications). The compile issues are related to

• sysctl: finding the number of CPUs
• detecting the number of columns for the progress bar

I've generated a patch against squashfs3.4, and I'm attaching it here.

Save the patch into the squashfs-tools directory as patch.txt and run the following command:

Code:

patch -p2 < patch.txt

Note: You should be at a Cygwin prompt, and should have installed "patch" in your Cygwin.

I've edited the patch to remove some redundant changes.
