Title: mount fails on tc-load
Post by: ormris on August 07, 2015, 03:06:29 PM

Hi Everyone,

I used the instructions in the Tiny Core Book to create an extension. Since I already had a build tree, I only needed this command.

$ mksquashfs app.tcz /tmp/buildroot/

This tcz file was copied to my tiny core VM, but I was unable to install it.

$ tce-load -i fapp.tcz
mount: mounting /dev/loop47 on /tmp/tcloop/app failed: Invalid argument

I'm using the lastest Tiny Core Plus image. Is there something I'm missing here?

You should not be including the while build tree.
You should be constructing the usr/local tree structure for your app in a work directory, and squashing that.

Also your problem description has inconsistent naming for the application.
You use app in some lines, and fapp in another.

Hi. Thanks for the reply.

The my buildroot contains only the files that are installed.

The fapp was a mistype in this forum post. I didn't actually type that in the command line.

Is there anything else I need to do, other than building the install tree and squashing it?

Thanks!
Matthew

Did you copy the tcz to /etc/sysconfig/tcedir/optional ?

Yes. I attempted to use the GUI application installer first.

Thanks!

So it is working now?

Sadly, not. I had the same problem.

Does the /tmp/tcloop/app already exist?
If it does, you will need to reboot and try again.
Also, make sure you have not loaded util-linux
This will make sure the wrong version of mount is not being run.

OK. The directory exists, so I'm rebooting now.

Unfortunately, same result after reboot.

EDIT: I don't have util-linux loaded.

Show the output of 'unsquashfs -l /etc/sysconfig/tcedir/optionall/app.tcz'

You did NOT follow Core guidelines.
You should not be installing anything in /etc/ , /usr/lib , /usr/share , or /usr/bin.
These locations are reserved for the OS.
All packages should load everything under /usr/local/.

Title: Re: mount fails on tc-load
Post by: ormris on August 07, 2015, 07:37:19 PM

OK. I'll rebuild with a /usr/local tree.

Thanks!

You should get squashfs-root/usr/local/bin/app - /usr is missing

So basically you'd have:

/tmp/pkg/usr/local/bin/app
/tmp/pkg/usr/local/bin/app_delta
...

Then:

Code: [Select]

$ cd /tmp
$ sudo mksquashfs pkg/ app.tcz

dmesg may contain more info on why the mount failed. Also, if you used mksquashfs from another OS, the blocksize needs to be given as 4k.

Title: Re: mount fails on tc-load
Post by: gerald_clark on August 08, 2015, 10:04:48 AM

/usr/local, not /local.

Apparently, you have not read and understood the wiki articles on creating extensions.

I have no idea what you have loaded or done to make tce-load fail with a mount error.

Also do not see version and architecture info.
