NTFS module compilation

[bentradio]

Thanks for your very informative article on how to enable NTFS support on Linux.
http://www.getlinuxonline.com/omp/di.../ompntfs2.html

I followed along very closely, but I still had a couple of problems:

I assume this line:
mkdir /lib/modules/2.4.18-4/kernel/fs/ntfs


should be this:
mkdir /lib/modules/2.4.18-5/kernel/fs/ntfs


Small difference but if you are cutting and pasting like I was :) , then it wouldn't work.


My other problem was that after everything seemed to work, I got

[root@localhost linux-2.4.18-5]# /sbin/depmod -a
depmod: *** Unresolved symbols in /lib/modules/2.4.18-5/kernel/fs/ntfs/ntfs.o


so I ran this:
[root@localhost linux-2.4.18-5]# /sbin/insmod

I don't know enough about the linux kernel (this is my first shot at messing with anything) to know what might have gone wrong. I'd appreciate it if someone could point me in the right direction.

Yes, that is a typo in the article that needs fixing.

My other problem was that after everything seemed to work, I got

[root@localhost linux-2.4.18-5]# /sbin/depmod -a
depmod: *** Unresolved symbols in /lib/modules/2.4.18-5/kernel/fs/ntfs/ntfs.o

This is usually caused by compiling the module using the wrong kernel config file.

What does this show:

rpm -q --qf '%{NAME}-%{VERSION}-%{ARCH}\n' kernel

and/or this:

cat /var/log/rpmpkgs | grep kernel

and

uname -r

Post the results of those and we will go from there.

Yup, that was it, used the wrong config file. I was a little confused because although I downloaded the i386 source rpm for the kernel, when I ran

rpm -q --qf '%{ARCH}' kernel-2.4.18-5

it did return i686, and using the i686 config gave me a ntfs module that worked!

I still have not been able to mount the drive yet but I think it's because it's a ieee1394 drive and I don't have the kinks quite worked out there.


Thanks for the help and the quick reply.

Cool! 8) ;D
