- Status: VerifyBuild status: build_failed
- Concerns
- Srec2vmem.py is created under /workspace/tools, but Dockerfile comment says it should be at /root/tools (e.g., /root/tools). If Makefile CONVERT script expects /root/tools, build may fail due to a missing converter.
- Action: place the script at /root/tools or align Makefile path accordingly.
- Build error
- Exact error (trimmed): ERROR: failed to build: failed to solve: process "/bin/sh -c mkdir -p /workspace/tools && cat > /workspace/tools/Srec2vmem.py <<'PY' import argparse\n...PY" did not complete successfully: exit code: 1
- Immediate runtime errors from failing step:
- cat: import: No such file or directory
- cat: argparse: No such file or directory
- Failing command/step: Step 5/9: RUN mkdir -p /workspace/tools && cat > /workspace/tools/Srec2vmem.py <<'PY' ... PY
- Cause: Here-doc content intended to define a Python script is misinterpreted; shell treats "import" and "argparse" as files because the here-doc was not parsed as intended, so Srec2vmem.py was not created.
- Missing packages/files
- No missing OS packages cited. The issue is the here-doc content not being fed correctly to cat; Srec2vmem.py not created. Result: cat reports missing files (import, argparse) due to incorrect here-doc handling.
- Version/environment info
- Two different base images in stages:
- #4: FROM ubuntu:22.04@sha256:...
- #5: FROM ubuntu:jammy-20260217@sha256:...
- Indicates a multi-stage build pulling two different Ubuntu bases (22.04 vs jammy-20260217), causing environment inconsistencies.
- Summary of actionable items
- Align Srec2vmem.py location with build tooling (move to /root/tools or adjust Makefile path).
- Fix here-doc feed to correctly create /workspace/tools/Srec2vmem.py (ensure the here-doc content is passed as a literal, not parsed prematurely).
- Harmonize base images across stages (use a single Ubuntu base or consistently versioned tags).FROM ubuntu:jammy-20260217

Summary of Docker build error
- Failing step (exact command):
RUN curl -L "$RISCV_TOOLCHAIN_URL" -o /tmp/riscv_toolchain.tar.xz && tar -xJf /tmp/riscv_toolchain.tar.xz -C ${TOOL_PATH} --strip-components=1 && rm -f /tmp/riscv_toolchain.tar.xz
- Exact error messages and exit code:
- xz: (stdin): File format not recognized
- tar: Child returned status 1
- tar: Error is not recoverable: exiting now
- The build exit code for the RUN step: 2
- Missing packages or files mentioned:
- None explicitly missing; the failure is due to the downloaded RISCV toolchain tarball not being a valid xz archive. The curl output shows a small download (likely an incorrect URL or access issue), leading to tar/xz failing.
- Version mismatch information:
- Dockerfile shows two different Ubuntu base images:
- Stage 3: FROM docker.io/library/ubuntu:22.04@sha256:ce4a593b4e323dcc3dd728e397e0a866a1bf516a1b7c31d6aa06991baec4f2e0
- Stage 5: FROM docker.io/library/ubuntu:jammy-20260217@sha256:ce4a593b4e323dcc3dd728e397e0a866a1bf516a1b7c31d6aa06991baec4f2e0
This indicates a mismatch between an explicit jammy-20260217 base and Ubuntu 22.04, which could cause inconsistencies.
Notes:
- The root cause appears to be the RISCV toolchain URL not serving a valid .tar.xz file (curl retrieves invalid content), not a missing package in apt. Check RISCV_TOOLCHAIN_URL, network access, and content validity, and consider validating the downloaded file before tar extraction.FROM ubuntu:jammy-20260217

Summary (under 1500 chars)
- Failing command/step
- RUN make -C lib FILE=firmware
- Exact error messages and exit code
- /usr/lib/riscv64-unknown-elf/bin/ld: cannot find -lc
- /usr/lib/riscv64-unknown-elf/bin/ld: cannot find -lm
- /usr/lib/riscv64-unknown-elf/bin/ld: cannot find -lc

- collect2: error: ld returned 1 exit status
- Makefile:64: firmware.elf
- Exit code: 2 (top-level failure: process "/bin/sh -c make -C lib FILE=firmware" did not complete successfully: exit code: 2)
- Missing packages/files mentioned
- The linker cannot find the target C library components: -lc (libc), -lm (libm), and -lgloss (libgloss)
- This implies the RISCV cross-toolchain’s libs/sysroot for riscv64-unknown-elf is missing or not in the linker’s search path, despite apt installing gcc-riscv64-unknown-elf, binutils-riscv64-unknown-elf, etc.
- Version mismatch info
- Multi-stage base images show a mismatch in base tags:
- Stage using: ubuntu:jammy-20260217
- Builder stage using: ubuntu:22.04
- This could contribute to toolchain/library availability discrepancies across stages.
- Context notes
- The build installed cross-compiler tools (gcc/riscv64-unknown-elf, binutils-riscv64-unknown-elf) but the required target C library and libgloss were not present for linking, causing the linker errors.How can I configure my DNS settings on Debian 12? https://serverfault.com/questions/1145358/how-can-i-configure-my-dns-settings-on-debian-12 Oct 7, 2023 · I'm trying to change my DNS settings on my Debian 12 VPS, and by this I mean, I want to use a public resolver like … How can I list my open ports on Debian? - Server Fault https://serverfault.com/questions/357323/how-can-i-list-my-open-ports-on-debian What is the command to display a list of open ports on a Debian server?

- Missing packages/files or path issues mentioned
- The target directory for links does not exist: /opt/riscv/bin (the previous step only created /opt/riscv/lib). As a result, the symlink creation fails with No such file or directory.
- Context: Step 7 runs mkdir -p /opt/riscv/lib, but no mkdir -p /opt/riscv/bin was executed.

- Other related libs: libexpat1, libmpc3, libmpfr6, libpython3-stdlib, python3.10-minimal, etc.
- No explicit mismatch reported, but the missing /opt/riscv/bin directory caused the symlink failure despite these packages being installed.No results found.

- Packages/versions observed:

- binutils-riscv64-unknown-elf 2.35.1-0ubuntu1
- Path/version notes:
- Base images: jammy-20260217 vs ubuntu:22.04 in builder stage; indicates cross-version/toolchain path inconsistencies.
- Toolchain binaries exist under /usr/bin, not /opt/riscv/bin.
- Root cause (summary): Dockerfile expects RISCV toolchain under /opt/riscv, but apt-installed binaries reside in /usr/bin, causing /opt/riscv/bin/riscv64-unknown-elf-gcc to be missing.
- Quick fixes (choose one):
- Install or symlink the toolchain into /opt/riscv/bin/riscv64-unknown-elf-gcc, or
- Change the Dockerfile to call /usr/bin/riscv64-unknown-elf-gcc, or
- Update PATH to include /usr/bin (if not already).
- Additional notes:
- The build uses a dummy libc/libm/libgloss in the toolchain sysroot (hacky, may mask real issues).
- Final CMD leaves an interactive shell; adjust if automating smoke tests.FROM ubuntu:jammy-20260217

CMD ["/bin/sh"]
Concerns: Artifacts stage copies from the builder stage for firmware artifacts, but the build of lib/firmware (RUN make -C lib FILE=firmware) occurs in the final runtime stage, not in the builder stage. Therefore the artefacts stage cannot propagate the built firmware and will fail or produce empty artifacts., The final image effectively becomes the artifacts stage (last FROM), which only copies from the builder stage and does not include the runtime firmware or correct build outputs. This defeats the purpose of building in a multi-stage flow., COPY --from=builder /workspace/lib/firmware.elf (and similar) references non-existent paths in the builder stage, since the firmware is built in a later stage. This will cause docker build to fail., There is a logical mismatch in stage naming and usage (no named final/runtime stage to reference from the artifacts stage). The build should alias the runtime stage (e.g., AS runtime) and copy artifacts from that stage, not from the builder stage., Minor note: duplicate ca-certificates in apt-get install is unnecessary but not harmful.

- Exact error message and exit code
- Failing message (from the log): "configure: error: Building GDB requires GMP 4.2+, and MPFR 3.1.0+."
- The overall failing command exit code: 2 (Docker/Build shows “exit code: 2” for the failing make step)
- Failing command/step
- Failing step: [builder 6/9] RUN make -j$(nproc) in the Dockerfile (building riscv-gnu-toolchain)
- Symptom: make fails while building gdb-newlib, specifically at the GDB configuration step that requires GMP/MPFR
- Missing packages or files mentioned
- GMP 4.2+ and MPFR 3.1.0+ are required by Building GDB but are not satisfied in the environment
- Indirectly mentioned/warned about missing:
- Texinfo/Makeinfo (warnings like Makeinfo is missing)
- /usr/bin/file (reported missing during several configure steps)
- Note: The GMP/MPFR absence is the direct cause of the GDB build failure; the other items are ancillary warnings in the logs
- Version mismatch info
- Root cause is missing/older GMP and MPFR versions required by GDB (GDB requires GMP 4.2+ and MPFR 3.1.0+)
- No explicit GMP/MPFR version installed in the image; the error indicates a dependency mismatch rather than a minor version conflict
- Quick fix suggestions
- Install GMP and MPFR with required versions (e.g., via apt-get install libgmp-dev libmpfr-dev, ensuring versions ≥ 4.2 and ≥ 3.1.0)
- Install Texinfo (for makeinfo) and ensure the file utility is present (install binutils-doc, texinfo, file)
- Re-run the build: docker build should progress past GDB if dependencies are satisfied# Multi-stage Dockerfile to build Wujian100 Open project with a RISCV GNU toolchain (bare-metal)

Status and context
- VerifyBuild status: build_failed
- Concerns: CI may run long due to RISCV toolchain; final image may be large; build relies on repo layout (lib/firmware) and targets; layout changes could break image.
Build error details
- Exact error message and exit code:
- Error: configure: error: expat is missing or unusable
- Exit code: 2
- Context: during the gdb-newlib build, at the configure step for gdb (configure-gdb)
- Failing command/step:
- Failing step: RUN make -j$(nproc) in the Dockerfile
- Failing target: gdb-newlib portion (configure-gdb) fails due to missing expat
- Logs indication: configure: error: expat is missing or unusable; subsequent failures (exit 2)
- Missing packages/files mentioned:
- expat: expat library/headers not available to configure
- Typical fix: install libexpat1-dev (or equivalent per distro)
- Earlier log note: bison not installed
- If a later step relies on yacc/bison, install bison (e.g., apt-get install -y bison)
Environment and version notes
- Base image: Ubuntu Jammy (jammy-20260217)
- GCC-related observations: package activity shows upgrades to gcc-12-base, libgcc-s1, libstdc++6, while builds reference GCC 11 toolchain; suggests mixed GCC versions and potential compatibility issues. Pin or align GCC version with toolchain docs.
Remediation steps
- Install missing dev headers:
- apt-get update && apt-get install -y libexpat1-dev
- If needed, install yacc/bison:
- apt-get install -y bison
- Ensure GCC/toolchain consistency:
- Pin GCC version or align to the required toolchain (prevent mixing GCC 11 and 12)
- Re-run the build after dependencies are in place (docker build or the same Dockerfile stage)
Note
- Core blocker: expat (and possibly its dev headers). Final docker exit is due to expat failure during configure (exit code 2).
Summary (under 1500 chars):
VerifyBuild ended in build_failed. The build failure centers on expat missing during gdb-newlib configure (configure-gdb), with exit code 2. The failing Docker step is RUN make -j$(nproc), in the gdb-newlib target. Actionable fixes: install expat dev headers (libexpat1-dev) and, if needed, bison. The base image is Ubuntu Jammy (jammy-20260217); note a GCC version mix (gcc-12-base/libgcc-s1/libstdc++6 updating while builds reference GCC 11), so pin or align the GCC toolchain. Remediate by ensuring libexpat1-dev (and optionally bison) are installed before building, verify GCC version consistency, then re-run docker build.# Multi-stage Dockerfile to build Wujian100 Open project with a RISCV GNU toolchain (bare-metal)

Summary (under 1500 chars): - Failing step/command: builder 6/9 failing at RUN make -j$(nproc) in /riscv-gnu-toolchain - Exact error messages and exit code (preserved): - error: RPC failed; HTTP 502 curl 22 The requested URL returned error: 502 - fatal: the remote end hung up unexpectedly - fatal: Fetched in submodule path 'newlib', but it did not contain 5e5e51f1dc56a99eb4648c28e00d73b6ea44a8b0. Direct fetching of that commit failed. - make: *** [Makefile:349: /riscv-gnu-toolchain/newlib/.git] Error 128 - What was being built when it failed: riscv-gnu-toolchain (submodules: newlib) during the make step of building the toolchain - Missing packages/files mentioned: None explicitly missing; the failure is due to a Git submodule fetch error (HTTP 502) and a missing commit in the newlib submodule, not a filesystem/package installation issue - Version/compatibility notes in logs: - Base image: ubuntu jammy (tag shows ubuntu:jammy-20260217) - The configure step in the previous build step issued: ./configure --prefix=/opt/riscv --with-newlib --disable-werror and emitted warnings: “unrecognized options: --with-newlib, --disable-werror” - Apt install portion ran and upgraded/installed many GCC-related packages (e.g., gcc-11/gcc-12 bases, libstdc++6, etc.), but there is no explicit version mismatch error reported; the root cause is the submodule fetch failure.
