How to create a remastered ISO with extra extensions added?
« on: November 25, 2022, 09:26:13 AM »
I'm trying to create a TinyCore ISO with extra software, but none of the extensions I add will execute.

Code: newbielink:javascript:void(0); [nonactive]
mkdir ./tc-iso
sudo mount TinyCorePure64-13.1.iso ./tc-iso -o loop,ro
cp -a ./tc-iso ./new-tc-iso
sudo umount ./tc-iso

chmod +w new-tc-iso/cde/{optional,onboot.lst}
cp vim.tcz new-tc-iso/cde/optional/
md5sum vim.tcz > new-tc-iso/cde/optional/vim.tcz.md5.txt
echo vim.tcz >> new-tc-iso/cde/onboot.lst
chmod -w new-tc-iso/cde/{optional,onboot.lst}

sudo genisoimage -l -J -r -V tc-custom -no-emul-boot -boot-load-size 4 -boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -o tc-custom.iso new-tc-iso

qemu-system-x86_64 -m 512 -cdrom tc-custom.iso

Adding bootcodes "showapps pause" show vim IS included in list of extensions

Code: newbielink:javascript:void(0); [nonactive]
tc@box:~$ tce-status -i | grep vim
vim
tc@box:~$ vim
sh: vim: not found
tc@box:~$ which vim
/usr/local/bin/vim
tc@box:~$ /usr/local/bin/vim
sh: /usr/local/bin/vim: not found
tc@box:~$ sudo vim
sudo: unable to execute /usr/local/bin/vim: No such file or directory


What do I need to do to make it work?

Thanks Rich.

I guess I got unlucky with the "simple" package I picked to test with.

After adding those dependencies, it adds Vim to the Apps menu, but selecting it only momentarily flashes up a terminal, starting terminal then entering "vim" has the same error as before.

It also adds GVim to the menu - despite not having added gvim.tcz itself (looks like there's desktop files in gvim-base that should probably be in the vim and gvim extensions), so I'm guessing there may be further dependency mixups causing the failure.

Is there a way to see actual errors, rather than just "not found"?

(Fulfilling gvim dependencies involves gtk3 so I'd rather avoid that rabbit hole.)

I tested with various other extensions and dependencies and they've all worked fine.

Hi boughtonp
A few thoughts come to mind:

Run this:
Code: [Select]
ldd $(which vim)and see if it reports  Not found  for any of the entries.

Try starting  vim  in verbose mode:
Code: [Select]
vim -VMaybe one of the messages it spits out will provide a clue.

Try booting the ISO directly. Maybe  Qemu  is creating the problem.

It could also be that you accidentally downloaded 32-bit vim.tcz, the extensions must match the iso's arch. That "not found" error is also shown for not found dynamic linker.
The only barriers that can stop you are the ones you create yourself.

Hi boughtonp
It could also be that you accidentally downloaded 32-bit vim.tcz, ...
If that's the case, then the  ldd  command I posted should report something similar to this:
Code: [Select]
wrong ELF class: ELFCLASS32

Thanks both, ldd confirmed that I had indeed downloaded the 32-bit version. :$

Not sure how I managed that, but I downloaded the correct vim.tcz and it works now.
