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.

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

1.0.134

Steps to reproduce

sudo snap install bun-js
bun install -g opencode-ai
TMPDIR=~/.opencode/tmp opencode --print-logs --log-level DEBUG

Operating System

> cat /etc/issue                                                                                                                                                                               Ubuntu 24.04.3 LTS \n \l

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

For *nix users having this issue, here's a drop-in wrapper command based on this answer:

opencode() {
    local tmpdir="$HOME/.opencode/tmp"
    mkdir -p "$tmpdir"
    BUN_TMPDIR="$tmpdir" command opencode "$@"
}
