hello ~ there

Q's: not happen on embeed linux after mounting using ntfs-3g new version 2009.4.4

I'm working on Embeed linux with samsung 2440 cpu. it means I'm on embeed linux not PC type linux
linux version is 2.6.21

I compiled ntfs-3g-2009.4.4 with
./configure --with-kernel=/linux direcotyr --host=arm-none-linux-gnueabi CC=arm-none-linux-gnueabi-gcc CFLAGS=-mcpu=arm920t --prefix=$(pwd)/out --exec-prefix=$(pwd)/out

kernel config condition : set to support FUSE_FS

there is no error

after compiling I copied the directory of "out" already set by configure time into /root filesystem on embeed linux

fdisk -l says that
/dev/sda1 NTFS

so I mounted like
ntfs-3g /dev/sda1 /mn/hdd
no error

but I didn't see anything after mounting
so I run command "mount"

but there was no mount poing with NTFS.

Q 1: So How am i supposed to do after failing reading NTFS.
Q 2: NTFS-3g-2009.4.4 document says that it doesn't reuqire FUSE
Is it real ????
Because I just follow README, but nothing happens

thanks in advance

because of mounting failed
I retryed to mount by using mount command on linux like

mount -t ntfs-3g /dev/sda1 /mnt/hdd
where /mnt/hdd is already maid.

but error is "mount:mounting /dev/sda1 on /mnt/hdd failed : No such device"
??????

You have no error message because your environment (shell?) closes stderr, what it shouldn't, when it calls ntfs-3g.

The "No such device" error means that there is no device driver in your kernel for your device (see more in open(2)). ntfs-3g can mount a volume only if the the device is handled by its device driver. This is a kernel problem, unrelated to ntfs-3g.

thanks for answer !!

to work properly I compiled fuse-2.7.4 with kernel-module like
./configure --with-kernel=/kernel directory --host=arm-none-linux-gnueabi CC=arm-none-linux-gnueabi-gcc --prefix=$(pwd)/out --enable-kernel-module --disable-mtab

I had seen no error for compiling

after that i run command

insmod fuse.ko

error happens like
fuse : no version for "strcut_module" found : kernel tainted.
fuse : unknown relocation : 40
insmod : cannot insert 'fuse.ko' : invaild module format

To solve isseue I had serached one but artcle sys that plelase insert command option "--with-kernel"
but I already set it.

condition : linux-2.6.21 (not patched for NTFS-3g"

would you please help me to proceed ?

thanks in advance.

The kernel and the FUSE module was built with different config options.

thanks for your helping me continusely

even though I don't catche that

as i understand with "--with-kernel" it's ok to compile with sysncronize fuse module and running linux version.

On embeed machine sys after running command "uname -r"

2.6.21-falinux

I think that it's ok becuase i compiled with this version linux with arm-cross-compiler named "arm-none-linux-gnueabi-xxx"
the other program (module) is ok in Makefile with "KERNELDIR =/xxx/linux-2.6.21"

????

Would give me the clue to solve ???

Thanks in advancd.

I'm glad to why there is issue when inserting module named fuse.ko
it is realted with speacial path for ARM. espeically for armv4

after patching file for ARMV4 patch related with "R_ARM_V4BX"

ok
but saddly has issue like
insmod : cannot insert "fuse.ko" : device or resoure busy

Why ??

but happy to solve and proceed a little bit

because of faing to complete insertion of fuse.ko

I looked into fuse code and kernel sorce tree

finally found it out

It's realted with EBUSY.

at this time I am not sure but after getting rid of fuse modue supproted by orinally kernel 2.6.21

It's ok but

after running below
ntfs-3g /dev/sda1 /mnt/hdd
there is no issue

oddly I did not see ntfs mouting porinted after run mount command

Woudl please help me with the clue

Thanks in advance.

this is a report of the issue refering to "strace NTFS-3g /dev/sa1 /mnt/hdd"
this below is shown after running strace

Would please give me the clue ????

Thanks in Advance

SIGILL means illegal machine instruction. The cross-compilation tool-chain doesn't match the run-time environment.

I'm glad to annouce that NTFS-3G is working properly

As the leader of ntfs-3g sys that it's realted with cross compiltation issue.

thanks for helping me

another Q's

Would you please give clues to use stable version between fuse and ntfs-3g
I have used different version
fuse-2.7.4
ntfs-2009.4.4

Is it right choice ?

Those versions are ok. But please note that the performance won't we be very great. If you're interested then we have a commercial driver which has 10-20 times better data transfer speed and up to 100 times better metadata performance: http://ntfs-3g.org/commercial.html
