Difficulty: 3/5
Estimated time: 1-2 days
Newbie friendliness: 38/100

Issue type: Bug
Clarity: Mostly clear
Activity status: Stale
Tech stack: cpp
Domain: build-system, operating-systems

Research direction

Start by examining libs/process/src/ext/cmd.cpp around lines 315 and 326, where the NetBSD build reports that vec cannot convert to boost::process::v2::shell. Reproduce the 1.86.0 build with the shown compiler settings and investigate the return type mismatch. Done means the Process sources compile successfully on NetBSD.
