wooow. That is the first time I ever seen that error :(
Can you try -d switch instead of -f. It will dump some output from FUSE.

Also this always confusing me - mounted files aren`t visible on samba or NFS mounts.

EDIT: ok, i see i have to read the rar2fs comunity page on google to get some answers. Thanks for helping, Hans :)
sorry, htg to spend some attention to my wife, you know, Valentine`s day ... :oops:

Hmmm. From the looks of it everything works fine until the first read. The first read is most probably an access made by the MediaPlayer to read the header.
Then it is closed by the MediaPlayer. But for some reason the close results in the unexpected death of a thread :(
We can take the Samba/NFS issue later, seems that it does not make sense to solve that until I can figure out why rar2fs crash on this system.
What we (or actually you since I can obviously not reproduce this error myself) is to build rar2fs in debug mode. You do that by specifying --enable-debug
in the list of options to configure. Then you run it with the -f switch (not -d). Note that this will produce a lot of output so attach it as a file ;)

No problem. But also, just to out rule one posibility. Can you try to mount the source folder that *contains* the .rar file instead of mounting the actual file to ./test?
Just want to see if it makes a difference or not.

Mounting directory, containing rar files gives no error, but trying to access this directory, console freezes and mediaplayer is showing endless "loading" - i think it couldn`t reach files inside that dir.
Exlink debug:

You most likely have stale obsolete files in your build directory.
Since you got to version 1.14.0 by recompiling there seems to be a mismatch somewhere.
Can you use automake on this platform ?
The old make system that you are using does not support --enable-debug, also the old make system is obsoleted with the release of 1.14.0.
I think it would be a good idea if you used ./configure;make procedure instead. It is more portable.
If you for some reason must stick to the old make, do a 'make clean;make DEBUG=4'

From the looks of your MediaPlayer log it looks like it fails to obtain stats of the file. It is most likely some access problem to the mounted folder.
Do you know what effective user id the MediaPlayer is using when accessing the file system ?
It was a little strange that you mount point shows uid=99,gid=99 of the file. Since you mounted as root it should be 0.
Do a ls -l on the file too, I wish to see how it looks like.

Since ./configure is not found, i used another way... I`m not sure what command should i use. I always use make clean before to compile something. Now trying with DEBUG=4.

./configure you get if you download the tar-ball from the site instead of getting it from the trunk.
If you took it from the trunk you do:

Code: Select all

# autoreconf -f -i
# ./configure <options>
