mounting an ISO image   
Hi All, 

I have an ISO image and I want to mount it.
fs-cd.so is present in /mnt/net/target/qnx6/armle/lib/dll. 

These are the commands I tried:

1. mount -vvv -tcd FUN.iso /mnt/cd

Parsed: mount from [FUN.iso] mount on [/mnt/cd] type [cd] 

exec: mount_cd FUN.iso /mnt/cd

Using internal mount (mount_cd not found)

Type    [cd] Flags 0x00000000 

Device  [FUN.iso] Directory [/mnt/cd] 

Options [NULL] 

mount: Can't mount /mnt/cd (type cd) 

mount: Possible reason: Invalid argument

 

2. mount -vvv -tiso9660 FUN.iso /mnt/cd

Parsed: mount from [FUN.iso] mount on [/mnt/cd] type [iso9660] 

exec: mount_iso9660 FUN.iso /mnt/cd

Using internal mount (mount_iso9660 not found)

Type    [iso9660] Flags 0x00000000 

Device  [FUN.iso] Directory [/mnt/cd] 

Options [NULL] 

mount: Can't mount /mnt/cd (type iso9660) 

mount: Possible reason: Invalid argument

 

3. mount -vvv -tcd loop FUN.iso /mnt/cd 

Parsed: mount from [loop] mount on [FUN.iso] type [cd] 

exec: mount_cd loop FUN.iso

Using internal mount (mount_cd not found)

Type    [cd] Flags 0x00000000 

Device  [loop] Directory [FUN.iso] 

Options [NULL] 

mount: Can't mount FUN.iso (type cd) 

mount: Possible reason: Invalid argument

 

I guess mount internally execs and calls mount_type (type we pass: cd, iso9660) but that, it is not able to find.
I tried to see symbols in fs-cd.so, and there is no such symbol present.

 

Please suggest me what I am missing

regards:
Ashutosh

Re: mounting an ISO image   
I think you are missing devb-loopback supposed to be shipped with QNX6.4.2.
For now you would have to place the iso locally on your "devb -host", eg in /tmp and not in /mnt.... , with mnt being a 
cifs mount.

> I did not get you. Could you please elaborate on your response.

I mean:

# uname -a
QNX EADE7784 6.4.1 2009/05/20-17:35:31EDT x86pc x86

what is mounted:

# mount
/dev/hd0t179 on / type qnx6
(SomeFileServer)192.168.x.x:/qnx on /qnx type CIFS/SMB

Trying to mount the rtkit iso on the fileserver:
 
# mount -tcd /qnx/Jeevan/rtkit.iso /rtkit
mount: Can't mount /rtkit (type cd)
mount: Possible reason: No such device or address

it failed.

copied the iso to /tmp and try to mount:

# mount -tcd /tmp/rtkit.iso /rtkit

it worked:

# cd /rtkit/

# pwd

/rtkit

# ls
.                ..               .info.           boot             instflop.dat     repository       rtinstall
#

Hope this helps.

PS however, actually I am not sure anymore if you have the same prb.

Re: RE: mounting an ISO image   
Thanks a lot for your help.
Can you try the attached test.iso image. Just to confirm that our iso image is proper.

Check if you have fs-cd.so on your platform.

Totally wrong :-) :

I do not have a blah.iso present here so:

# mount -vvv -tcd blah.iso /root/Ashutosh/test
Parsed: mount from [blah.iso] mount on [/root/Ashutosh/test] type [cd]
exec: mount_cd blah.iso /root/Ashutosh/test

In your first post you have the invalid arg error above.

Re: RE: mounting an ISO image   
I think because of devb-eide you are able to mount.
Slay the devb-eide process and try once.

In our case we dont have any ide devices and we are not running devb-eide devices.

I think only solution in our case is using loopback. But we dont we have devb-loopback. 

could you help me in getting devb-loopback exe for ARM target?

Hmm I am not sure:
But previously I wrote:

Yes, that should be easy:
Can you contact your >next<  support-rep via the 'new' support portal  ?
