can not start opencode on ubuntu /tmp does not allow execution of .so

[falko-apheris]

Description

When trying to run opencode it tries to execute/use a shared object file from the /tmp directory, however execution of shared object files on Ubuntu is blocked for security reasons.

> TMPDIR=~/.opencode/tmp opencode --print-logs --log-level DEBUG                                                                                                                               <region:eu-central-1>

it would be nice if the tmp directory could be specified or a common directory like ~/.local/share/opencode could be used on systems with standard security hardening.

OpenCode version

This issue might be a duplicate of existing issues. Please check:

• #4743: [FEATURE]: allow /tmp or $TMPDIR folder access option

This is a feature request to allow write access to /tmp or specify a custom TMPDIR, which would address the security hardening issue you're experiencing on Ubuntu. Feel free to ignore if your specific case requires a different solution.

follwing the link of the actions box, I found a fix

BUN_TMPDIR=~/.opencode/tmp opencode --print-logs --log-level DEBUG    

I would still wish that opencode would work out of the box
