Stuck building on palera1n arm64 device - need help

[Einstein2150]

Building on macOS is fine but I have issues compiling it on the device directly:

Any chance to run node.js / npm? nvm can't install a compatible version:

I'm on palera1n rootless
iPad6,7 16.7.2

...or is there a deb-package or a compiled bin somewhere to find?

Hi @Einstein2150, can you try first installing xz and then try to install nvm.

[Einstein2150]

OK. That makes sense but now it's more confusing

# nvm install --lts

$>./configure --prefix=/var/jb/var/root/.nvm/versions/node/v20.9.0 <

nvm: install v20.9.0 failed!

And now:

./configure: 6: exec: /bin/sh: not found
🙄
How could that be. It's useable in the terminal and I'm root ...

# sh
# id
uid=0(root) gid=0(wheel) groups=0(wheel)

... but its symlinked and not in /bin/sh . Because the jailbreak is rootless I have no write permission into this system-folder

# where sh
/var/jb/usr/bin/sh
/var/jb/bin/sh

That's sad ...

[Einstein2150]

Now I manually un-xz-ed the archive and modified line 6 in configure from /bin/sh to /var/jb/bin/sh. It runs but ...

# ./configure
