Validate

Run the full rocDecode validation pipeline. Execute these steps in order, stopping only if a step fails. Run from the rocDecode project root (the directory containing this repo's build/, samples/, and test/ directories).

IMPORTANT: Run each command as a SEPARATE Bash tool call. Do not chain commands with && or |.

The build derives its compiler, install prefix, and CTest data path from ROCM_PATH (default /opt/rocm). If ROCm is installed elsewhere (e.g. a TheRock or custom build), ROCM_PATH must be set. NOTE: skills run cmake in a NON-interactive shell that does not source ~/.bashrc, so set ROCM_PATH in ~/.profile (or export it before launching Claude Code) — otherwise the build silently falls back to /opt/rocm. Step 1 verifies this and fails fast with guidance if the toolchain is missing.

Conformance test data (Phase 4) is located via the ROCDECODE_CONFORMANCE_DIR environment variable, which defaults to $HOME/rocDecodeConformance. It must contain the per-codec subdirectories AvcConformance, Av1Conformance, HevcConformance, and Vp9Conformance. Codecs whose directory is missing are reported as WARNING and skipped, so the pipeline still runs without the full data set.

Step 1 — Verify the ROCm toolchain

Run: test/validate.sh --check-rocm

This confirms ROCM_PATH points at a usable ROCm install (the compiler exists) and that the install prefix is writable before any build work — make install installs into ROCM_PATH, so a read-only prefix like a system /opt/rocm would need sudo, which this skill does not use. If it fails, fix ROCM_PATH (see the note above; point it at a user-writable install) and re-run before continuing. Do not retry without changing ROCM_PATH — if it cannot be resolved, stop and ask the developer.

Step 2 — Configure, clean, rebuild, and install the core library

The build/ directory is not checked into the repo, so on a fresh checkout it must be created and configured first. cmake -B build -DENABLE_EXTENDED_TESTS=ON is idempotent — it creates and configures build/ if missing, and is a cheap no-op if it is already configured. -DENABLE_EXTENDED_TESTS=ON enables the additional FFmpeg-based CTest cases (the CTest phase covers 6 tests without it, 15 with it); those extra tests are only added when FFmpeg is found, so the flag is harmless on machines without FFmpeg.

Run these four commands separately:

1. cmake -B build -DENABLE_EXTENDED_TESTS=ON
2. make clean -C build
3. make -j -C build
4. make install -C build

(make -j lets make choose parallelism without a $(nproc) command substitution, which would otherwise trigger a permission prompt on every run.)

Step 3 — Build all sample apps

Run: test/build_samples.sh

Step 4 — Run validation

Run: test/validate.sh
