OpenROAD/etc/Dockerfile.claude

# Docker image for running Claude Code with --dangerously-skip-permissions
# inside a container that can build/test OpenROAD (CMake + Bazel).
#
# Usage: see claude.sh at the repo root.

# Ubuntu 24.04 provides glibc 2.39, required by the LLVM 20 toolchain
# that Bazel downloads (needs __isoc23_* symbols from glibc >= 2.38).

# VS Code CLI (code-tunnel for remote editing).

# variant on code.visualstudio.com is statically linked and also works,
# but the linux-x64 build from update.code.visualstudio.com is the
# canonical match for glibc distros.)
