Unfortunately no one can be told what fun_plug is - you have to see it for yourself.

Fuse packages for fonz fun_plug

I have compiled fuse-2.7.3 packages for fonz fun_plug 0.3/0.4 and 0.5, posting them here hoping that someone else finds them useful.

Fonz fun_plug 0.3/0.4:

Code:

# wget http://pof.eslack.org/dns323/fuse-2.7.3.tgz
# funpkg.sh fuse-2.7.3.tgz
# ${FUNPLUGDIR}/start/fuse.sh start

Fonz fun_plug 0.5-experimental:

Code:

# wget http://pof.eslack.org/dns323/fuse-2.7.3-ffp05.tgz
# funpkg fuse-2.7.3-ffp05.tgz
# /ffp/start/fuse.sh start

With FUSE it is possible to implement a fully functional filesystem in a userspace program, see some examples.

Enjoy ;-)

Hmm, interesting stuff, i'll take a look at it.

Re: Fuse packages for fonz fun_plug

Hi, I tried to launch fuse with your package, but I got this error message:

Code:

# ./fuse.sh start
/ffp/bin/fusermount
Loading fuse module.
Mounting fuse control filesystem failed!

I don't understand why. Can someone explain me, or help me to find the problem? Thank you wink

Re: Fuse packages for fonz fun_plug

Would this then allow use of the user-space ntfs-3g module?
If so, has anybody compiled it and tested it?

Re: Fuse packages for fonz fun_plug

Were you able to get fuse to work?
I tried compiling my own version for kernel 2.6.12.6 (including some of the fixes mentioned on the net) but when I tried it with ntfs-3g and with the hello example, it hung my kernel.

Can you say a little more about what you did to get it to compile and work properly?
What user space filesystems have you gotten to work with it so far?

Re: Fuse packages for fonz fun_plug

The problem with "Mounting fuse control filesystem failed!" is due to the fact that the mountpoint /sys/fs/fuse/connections doesn't exist.
Creating the mountpoint allows /ffp/start/fuse.sh to run without errors.

However, I still get that running something like ntfs-3g or the 'hello' example hangs and is unkillable.

Re: Fuse packages for fonz fun_plug

Hi, I tried to compile mhddfs, and I got this message:

Code:

How can I fix this? I assume that I'll have to modify the code, but I don't really know what to look for. Do you have an idea? Thanks.

Re: Fuse packages for fonz fun_plug

FP refers to Floating Point. OK. But I can't find any reference to any option in the makefile that tries to use software FP.

Re: Fuse packages for fonz fun_plug

Your libfuse is broken, mhddfs compiled correctly with soft-FP.

Re: Fuse packages for fonz fun_plug

Does anybody have an example of a working fuse file system on the dns-323?
Because everything I have tried to do just hangs the mount (which requires a reboot to clear)

Re: Fuse packages for fonz fun_plug

I have compiled fuse-2.7.3 myself for the CH3SNAS. Kernel module, gcc-3.3, etc. I can successfully load the kernel module, but nothing else works... sad

Whenever I try to use it I get a kernel error.

Anyone has any idea? I've attached the module. My kernel is 2.6.12.6-arm1, and gcc was compiled with the following:

Code:

[Configured with: /mnt/HD_b2/build/uclibc-toolchain-src-20040609/gcc-3.3.x/toolchain_build_arm_nofpu/gcc-3.3.3/configure 
--prefix=/mnt/HD_b2/build/uclibc-toolchain-src-20040609/gcc-3.3.x/toolchain_arm_nofpu --build=arm-pc-linux-gnu 
--host=arm-pc-linux-gnu --target=arm-linux-uclibc --enable-languages=c,c++ --enable-shared 
--with-gxx-include-dir=/mnt/HD_b2/build/uclibc-toolchain-src-20040609/gcc-3.3.x/toolchain_arm_nofpu/arm-linux-uclibc/include/c++ 
--enable-__cxa_atexit --enable-target-optspace --with-gnu-ld --disable-nls --enable-multilib --without-float --enable-sjlj-exceptions
Thread model: posix
gcc version 3.3.3

I was running the hello example of fuse. It starts correctly, but when I try to list the contents of the fuse-d dir, *bamm* the kernel error happens. I feel as if I am really close to getting this to work!! I hope!

Re: Fuse packages for fonz fun_plug

If anybody is interested; I've solved the problem!

One can argue on how much of a solution you want to call this; but the point is that everything works!
I could not get libfuse to work at all. I've finally installed the Alt-F RC1 (as a firmware), which upgraded my CH3SNAS[1] to Linux 2.6.35.14. The fuse module was already present in the kernel.

I've installed the libfuse-2.8.5 devel libraries, compiled davfs2-1.4.6 and now have everything working perfectly[2]! A webdav mount connection to google docs so I can back up my data simply with rsync big_smile

[1] I've flashed the CH3SNAS with the latest DNS-323 1.10 firmware first, hoping that would solve it, but they didn't change the kernel
[2] If someone wants, I can post binaries, although it won't work with the 2.6.12 kernel. I did end up upgrading to ffp 0.6 beta because I needed irssi as a funplug pkg which (long story short) didn't work with lower than uClibc-0.9.32 versions. Since I couldn't compile uClibc for some reason, I just used ffp-0.6's version. So the packages I created may work, or may not work with ffp-0.5.

Re: Fuse packages for fonz fun_plug

Glad it works for you but it truly is not a solution to the original problem. I mean new kernel will by default support fuse....
I similarly got it working with a debian distro and kernel... but again that is not a solution to the original problem....
