Thanks juan

Is it possible to create similar tools for DOS/Windows platform?

Using this new tool, user can recover/repair damaged Ext2fs/Ext3fs from DOS/Windows platform.

[Lakshmipathi]

Yes. i think it's possible to creat a Ext3/Ext2 tool for windows.
In fact i believe ,all existing tool which works for ext2/ext3 in Linux can also be implemented in Windows after making few changes.

[Lakshmipathi]

Hi juan,
I guess error that u got is because ext3_fs.h file is missing,
in your system.but i really how come that file be missing???
I hope if you can find that file then make sure it's placed at folder /usr/include
I hope it will work now.
i uploaded version giis3 of tool at
http://sourceforge.net/projects/giis/

[Juan Pablo]

Yes, my file is currently on /usr/include/linux/ex3_fs.h

[Lakshmipathi]

Hi juan,
This sunday,i formatted my harddisk and freshly installed linux fedora core-2.
I got same kind of problem which u said,
I displays .h files like -ext3_fs.h ,pwd.h files are not included.
But these files can be found at /usr/include.
So i tried to install all Gnome development tools and kernel development tools and system tools and admin tools from add/Remove programs option.
Then it worked.
I'm confused,what's really missing?
Can somebody help me?
In simple terms,When i install,it says files missing but files can be found in respective directories.
After i install some development tools -it started to work ...
