Uni20 Build Matrix

Overview

Run a compact but meaningful build matrix without assuming specific compiler install paths.

This skill is for compatibility checks, regressions, and release confidence. Keep matrix size proportional to the request.

Workflow

Read AGENTS.md, then .codex/instructions.local.md (if present).
Detect available compilers on the current machine.
Pick a minimal matrix that covers requested dimensions (compiler, build type, stacktrace/LTO toggles).
Select an out-of-source build root from the local override, the user's request, or a git-ignored default, then configure each cell under <build-root>/<cell-name>.
Summarize pass/fail per cell with failing targets/tests.

Compiler Detection

Prefer local toolchain overrides if documented. Otherwise auto-detect:

for cxx in g++ g++-16 g++-14 g++-13 clang++ clang++-21 clang++-20 clang++-19; do
  command -v "$cxx" >/dev/null && echo "$cxx"
done | awk '!seen[$0]++'

Reject Clang versions below the supported Clang 19 floor. Prefer GCC 13 as the compatibility baseline when it is available.

Matrix Construction Rules

Always include one baseline cell (default compiler, Debug).
Add Release when performance/packaging concerns are in scope.
Add UNI20_ENABLE_STACKTRACE=0 cell when async-debug/stacktrace behavior is relevant.
Add CMAKE_INTERPROCEDURAL_OPTIMIZATION=ON cell for LTO validation.
Add second-compiler smoke cell only if another compiler is installed and requested.

Configure Templates

Baseline:

cmake -S . -B <build-root>/<cell-name> -DCMAKE_BUILD_TYPE=Debug

Compiler override:

cmake -S . -B <build-root>/<cell-name> \
  -DCMAKE_C_COMPILER=<cc> \
  -DCMAKE_CXX_COMPILER=<cxx> \
  -DCMAKE_BUILD_TYPE=<Debug|Release>

Optional toggles:

-DUNI20_ENABLE_STACKTRACE=0
-DCMAKE_INTERPROCEDURAL_OPTIMIZATION=ON

Build and Test

cmake --build <build-root>/<cell-name>
ctest --test-dir <build-root>/<cell-name> --output-on-failure

For quick smoke checks, run targeted tests first, then full ctest if requested.

Reporting Format

matrix: list of executed cells and options
configure/build: pass/fail per cell
tests: pass/fail counts and failed test names per cell
notes: actionable follow-ups (cache cleanup, option conflict, compiler-specific failures)
