README: align with the actual state of the Release 2 branch

Verified every claim against new_docker_build_release2.sh, the DEB
producer and a real pipeline run, then removed/fixed what does not
belong to this branch:

- Removed Step 1 (--build-prebuilt-image/--delete-prebuilt-image): those
  options do not exist in the driver.
- Replaced the Release 1 bookkeeping (R1 packages table, R1 modules
  table, 38-target count) with the actual Release 2 scope: 46 targets
  (GROUP1 6, GROUP3 36, GROUP5 3, GROUP6 1).
- Fixed the build description: Ninja (not make -j8), unique
  build4_<timestamp>_<pid> dirs (not a shared build4/), the real cmake
  flags (BUILD_RTI, BUILD_GROUP*, RTI defines), no RELEASE_BUILD flag.
- Fixed image/mount facts: default image qt6-migrated-legatus-release2
  (not guez-release2:2.0), /repo mount root (not /workspace), no
  WORKSPACE env var, no build4/release_build.log.
- Fixed DEB names/contents: qt6-release-*_1.0-1_amd64.deb (not
  guez-*_2.0), real PIPELINE_FILES list, honest note that the
  ctest-runtime DEB is currently empty (build4 vs build4_<ts> mismatch).
- ctest baseline: 7 in-scope tests passed + the 9 expected Not Run
  entries.
- Options reference: real options/defaults (lts-version 1.0), env
  override list matching the driver; troubleshooting updated
  (offscreen Qt, RTI license, prebuilt image).

The group target lists are the `GROUP*_TARGETS` arrays in
`new_docker_build_release2.sh`.
## Entries at the tree root
- `new_docker_build_release2.sh` — Release 2 build driver (image build, compile, ctest, DEB packaging)
- `Dockerfile` — recipe of the prebuilt build image (Ubuntu 26.04 + Qt 6.10.2 + deps)
- `new_docker_build_release2.sh` — Release 2 build driver (compile, ctest, DEB packaging, coverage)
- `Dockerfile` — recipe of the build image (Ubuntu 26.04 + Qt 6.10.2 + deps)
- `rpmbuild/make_rpm_ubuntu26_release2.py` — Release 2 DEB package producer (5 packages)
- `jenkins-ci-rme/` — in-tree copy of the Jenkins CI flow (see its own `README.md`)
- `build4/` — build tree, created by the driver (git-ignored scratch area)
- `build4_<timestamp>_<pid>/` — per-run build tree, created by the driver (git-ignored via `build4_*`)
**Toolchain inside the image:** Ubuntu 26.04, GCC 15.2.0, Qt 6.10.2 (`/opt/Qt/6.10.2/gcc_64`), C++17, Release build.
**Qt Installation:** Qt 6.10.2 installed via `aqt install-qt` (no apt Qt6 packages).
**Toolchain inside the image:** Ubuntu 26.04, Qt 6.10.2 (`/opt/Qt/6.10.2/gcc_64`),
Ninja, C++17. Qt is installed via `aqt install-qt` (no apt Qt6 packages).
## Prerequisites
1. **Docker** available on the host.
2. The tree must be reachable inside the container at
`/workspace/qt-migration-legatus/qt6-after/qt6-migrated-legatus`, i.e.
mount the pipeline root on `/workspace` — this is how
`new_docker_build_release2.sh` invokes Docker, so running the driver as-is
satisfies this.
2. A prebuilt build image. The driver default is `qt6-migrated-legatus-release2`;
any equivalent prebuilt image can be selected with `--docker-image`
(or `DOCKER_IMAGE`).
The driver resolves the pipeline root from its own location (override
with the exported `MIGRATE_PIPELINE_ROOT` or the `.envrc` in this
directory).
The driver resolves the pipeline root with this precedence:
exported `MIGRATE_PIPELINE_ROOT` → `MIGRATE_PIPELINE_ROOT` from the `.envrc`
in this directory → derived from the script location. The pipeline root is
mounted in the container at `/repo` (override with `--docker-mount-root`), so
the tree is reachable at
`/repo/qt-migration-legatus/qt6-after/qt6-migrated-legatus`.
All commands below are run **from this directory**
(`qt6-migrated-legatus/`).
## Step 1 — Build the prebuilt Docker image (once)
## Step 1 — Compile the Release 2 scope
```bash
./new_docker_build_release2.sh --build-prebuilt-image --docker-image guez-release2:2.0
```
This builds the image from the in-tree `Dockerfile` (Ubuntu 26.04 base,
apt deps, Qt 6.10.2 via `aqtinstall`, KDReports from source). Re-run it
only after changing the `Dockerfile` or the `APT_PACKAGES` list in
`new_docker_build_release2.sh`.
To remove it later:
```bash
./new_docker_build_release2.sh --delete-prebuilt-image --docker-image guez-release2:2.0
```
## Step 2 — Compile the Release 2 scope
```bash
./new_docker_build_release2.sh --docker-image guez-release2:2.0
./new_docker_build_release2.sh --use-prebuilt-image --docker-image <image>
```
What the driver does inside the container:
1. `rm -rf build4 && mkdir build4 && cd build4` (fresh build tree)
2. Configure with CMake:
1. Creates a fresh build tree `build4_<timestamp>_<pid>` (unique per run).
2. Configures with CMake (Ninja generator):
```bash
cmake .. \
cmake -B build4_<ts> \
-G Ninja \
-DBUILD_TESTING=ON \
-DRELEASE_BUILD=ON \
-DCMAKE_CXX_STANDARD=17 \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_PREFIX_PATH=/opt/Qt/6.10.2/gcc_64:/usr/local
-DCMAKE_BUILD_TYPE=RelWithDebInfo \
-DCMAKE_PREFIX_PATH=/opt/Qt/6.10.2/gcc_64 \
-DCMAKE_CXX_FLAGS="-DRTI_LINUX -DRTI_UNIX" \
-DCMAKE_C_FLAGS="-DRTI_LINUX -DRTI_UNIX" \
-DBUILD_RTI=ON \
-DBUILD_GROUP1=ON -DBUILD_GROUP3=ON -DBUILD_GROUP5=ON -DBUILD_GROUP6=ON \
.
```
(`RELEASE_BUILD=ON` selects the Release 2 scope; everything else is at
its CMake default.)
3. `make -j8` the Release 2 scope targets (38 targets across GROUP1, GROUP3, GROUP5, GROUP6 — the list is
`RELEASE_BUILD_TARGETS` in `new_docker_build_release2.sh`).
4. Run **ctest** (see Step 3).
`BUILD_RTI=ON` is required: RTI codegen consumers (e.g. `svcPdmCommon`)
need the generated headers, and the `BUILD_RTI=OFF` stubs are not part of
this tree. The scope is selected by the `BUILD_GROUP*` flags.
3. Builds the 46 scope targets with `cmake --build ... --target <t>`
(Ninja, per target, in group order).
4. Runs **ctest** (see Step 2).
Output to inspect after the run:
Output to inspect after the run (in the run's `build4_*` dir):

- `bin/` — executables (apps + test binaries)

bash -c "cd /repo/qt-migration-legatus/qt6-after/qt6-migrated-legatus/${B} && ninja -j$(nproc)"
```
## Run an executable directly
To run a built executable interactively — e.g. the GUI apps under
`build4/bin/` (`LogView`, `PrtCnv`) against your local display — start a
`bin/` (`LogView`, `LogViewer`, `PrtCnv`) against your local display — start a
shell inside the container with X11 forwarding:
```bash
B=$(ls -dt build4_* | head -1)
docker run --rm -it \
-e DISPLAY \
-e LC_ALL=C.UTF-8 \
-v /tmp/.X11-unix:/tmp/.X11-unix \

## Troubleshooting
- **"no Qt platform plugin could be initialized"** when running a test
binary by hand → `export QT_QPA_PLATFORM=offscreen`.
- **Stale build tree** → the driver always recreates `build4/`; for
manual builds delete `build4/` and rerun Step 2 if CMake behaves oddly.
- **Stale build tree** → the driver always creates a fresh
`build4_<timestamp>_<pid>` dir per run; old dirs are git-ignored scratch
areas and can be deleted freely.
- **DEBs not on the host** → the output dir must be a path that exists
*on the host* (it is bind-mounted into the container as
`/workspace/packages-out`); check the `package-output-dir` argument.
- **Build fails with missing Qt modules** → ensure the container uses
`new_docker_build_release2.sh` which installs Qt 6.10.2 via `aqt install-qt`.
The image must be `guez-release2:2.0` (not `legatus-qt6:1.0`).
*on the host*; check the `--package-output-dir` argument and the
`rpms/<project>/<os>/` dir under the pipeline root.
- **Build fails with missing Qt modules** → the image must be a prebuilt
Release 2 image (Qt 6.10.2 installed via `aqt install-qt`); select it with
`--docker-image`.
- **DDS build fails on the license** → `rti_license.dat` must be present at
the source tree root; the driver exports `RTI_LICENSE` for in-container
use.
