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

• TUI fails on Alpine Linux (musl) in 1.14.50: getcontext symbol not found #27589: TUI fails on Alpine Linux (musl) - same getcontext: symbol not found error
• Opencode in docker container wont start opencode TUI #28314: Opencode in docker container won't start opencode TUI - same docker context
• opencode with musl static build? #28277: opencode with musl static build? - related musl/Alpine compatibility issue

The getcontext: symbol not found error typically occurs when running on a musl libc environment (Alpine Linux, or Docker images based on Alpine), as opposed to glibc. This is a known compatibility issue with the OpenTUI native library and musl libc.

Please check the above issues for any workarounds or ongoing discussion before continuing here.
