Missing packages/files mentioned
- No such target '@@local_cuda//:cub' declared in package '', defined by external/local_cuda/BUILD (i.e., missing cub target in local_cuda repository wiring)

Version/dependency notes
- Bazelisk attempted to fetch Bazel: downloading bazel-7.1.2-linux-x86_64 (Bazel 7.1.2). No explicit version mismatch reported beyond this failure.

- Missing packages or files mentioned:
  - no such target '@@local_cuda//:cuda_runtime_static': target 'cuda_runtime_static' not declared in package '' defined by /root/.cache/bazel/_bazel_root/eab0d61a99b6696edb3d2aff87b585e8/external/local_cuda/BUILD

- Version/mismatch information (from logs):
  - Bazel 7.1.2 is being downloaded/used: Downloading https://releases.bazel.build/7.1.2/release/bazel-7.1.2-linux-x86_64...

- Context note:
  - The error occurs during bazelisk fetch/build for //app/blitzar:blitzar, with CUDA-related rules_cuda processing leading to the missing cuda_runtime_static target. This suggests a mismatch or incomplete declaration in the external local_cuda BUILD or an incompatibility with the CUDA rules being used. Possible next steps include aligning the CUDA rule versions with the expected local_cuda targets, or disabling CUDA-related dependencies if CUDA is not required.

Docker build error summary

- Failing step (command/step):
  - RUN bazelisk fetch //... &&     bazelisk build //app/blitzar:blitzar
  - Exit code: 1

- Exact error messages (preserved):
  - "src/main/tools/process-wrapper-legacy.cc:80: \"execvp(/usr/local/cuda/bin/nvcc, ...)\": No such file or directory"
  - "ERROR: /workspace/sxt/field51/operation/BUILD:45:17: Compiling sxt/field51/operation/neg.cc failed: (Exit 1): nvcc failed: error executing CudaCompile command (from target //sxt/field51/operation:neg) /usr/local/cuda/bin/nvcc -x cu '-rdc=true' -Xcompiler -fPIC -ccbin /usr/bin/gcc -I . -I bazel-out/k8-fastbuild/bin -I . -I bazel-out/k8-fastbuild/bin -I external/local_cuda -I ...

  - (Also mentions additional similar failures for cmov.cc and sq.cc)

- Missing packages or files mentioned:
  - /usr/local/cuda/bin/nvcc (No such file or directory)

- Version/mismatch information:

  - Bazel launcher downloaded: bazel-7.1.2 (bazelisk fetch downloads bazel 7.1.2)
  - Implication: CUDA toolchain (nvcc) is not present in the image despite CUDA base image being used (nvcc missing). This is a mismatch between the expected CUDA toolchain in the image and what is actually available.

Summary:
- Exact error message and exit code:
  nvcc fatal   : Unknown option '-Wno-unknown-cuda-version'
  (Exit code 1 reported during nvcc compilation)

- Failing command/step:
  Builder step 7/7:
  RUN bazelisk fetch //...     && bazelisk build //app/blitzar:blitzar
  The failure occurs during the Bazel build of //app/blitzar:blitzar, specifically when compiling sxt/base/device/stream_handle.cc with nvcc.

- Missing packages or files mentioned:
  None explicitly listed as missing. The log shows a toolchain flag causing the failure, not a missing file/package.

- Version mismatch / environment info:
  - Base image/toolchain: docker.io/nvidia/cuda:12.6.0-devel-ubuntu22.04 (CUDA 12.6 devel), with nvcc at /usr/local/cuda/bin/nvcc.
  - Error indicates the nvcc in this CUDA toolchain does not recognize the flag -Wno-unknown-cuda-version, suggesting a mismatch between the build scripts (which pass that flag) and the installed nvcc version. This is a CUDA toolchain/flag compatibility issue rather than a missing dependency.

Exact error message
- ERROR: Fetching target dependencies for deps(//...) encountered an error: Evaluation of query "deps(//...)" failed: preloading transitive closure failed: no such target '@@local_cuda//:cub': target 'cub' not declared in package '' defined by /root/.cache/bazel/_bazel_root/external/local_cuda/BUILD

Missing packages/files mentioned
- The failure references a Bazel external target: '@@local_cuda//:cub' not declared in the external CUDA workspace (external/local_cuda/BUILD). This indicates a missing or undeclared CUDA target in the local_cuda Bazel config.

Version mismatch / hints
- DEBUG: Rule 'rules_cuda' indicated that a canonical reproducible form can be obtained by modifying arguments commit = "775ba0c41679aab6ee60425360bdd841aaf92bb6" (CUDA rules mismatch hint). This suggests a possible version/commit mismatch in the CUDA Bazel rules configuration.

- Missing packages or files mentioned
  - No missing-packages/files reported. The log shows successful apt installs prior to this step; the error is CUDA/NVCC flag related, not a missing file/package.
- Version mismatch info
  - CUDA toolkit in use: nvidia/cuda:12.3.0-devel-ubuntu22.04 (also 12.3.0-runtime-ubuntu22.04 in prior step)
  - The error suggests a compatibility issue between nvcc and the host toolchain (unknown flag -Wno-unknown-cuda-version), possibly due to CUDA/toolchain versions (nvcc invoked with /usr/bin/gcc and CUDA 12.3 tooling).

Exact error messages (preserved)
- ERROR: Failed to load Starlark extension '@@rules_cuda//cuda:repositories.bzl'.
- Cycle in the workspace file detected. This indicates that a repository is used prior to being defined.
- The following chain of repository dependencies lead to the missing definition.
-  - @@rules_cuda
- This could either mean you have to add the '@@rules_cuda' repository with a statement like `http_archive` in your WORKSPACE file (note that transitive dependencies are not added automatically), or move an existing definition earlier in your WORKSPACE file.
- ERROR: Error computing the main repository mapping: cycles detected during computation of main repo mapping
- -----
- process "/bin/sh -c bazelisk fetch //...     && bazelisk build //app/blitzar:blitzar" did not complete successfully: exit code: 37

Missing packages/files (caused by error)
- Missing repository definition: the Starlark extension is attempting to load '@@rules_cuda//cuda:repositories.bzl', but the @@rules_cuda repository is not defined (cycle in workspace leading to a missing definition).
- Suggested fix mentions adding the '@@rules_cuda' repository (e.g., via http_archive) in the WORKSPACE file or moving its definition earlier.

Version/tooling notes
- Bazelisk attempted to download Bazel v7.1.2 (log shows: "Downloading https://releases.bazel.build/7.1.2/release/bazel-7.1.2-linux-x86_64..."), indicating the Bazel version being used for the build.

Summary of Docker build error

- Failing step
  - [ 8/12] RUN bash -lc 'cat > /workspace/overrides/rules_cuda/cuda/defs.bzl << "EOF"\ndef rules_cuda_dependencies():\n  pass\n\ndef register_detected_cuda_toolchains():\n  pass\nEOF'

- Exact error messages (preserved)
  - bash: line 1: warning: here-document at line 1 delimited by end-of-file (wanted `EOFndef')
  - bash: -c: line 1: syntax error near unexpected token `('
  - bash: -c:  `cat > /workspace/overrides/rules_cuda/cuda/defs.bzl << "EOF"\ndef rules_cuda_dependencies():\n  pass\n\ndef register_detected_cuda_toolchains():\n  pass\nEOF'

- Context from log (version info)
  - Base image: gcc:15.2.0-trixie (sha256:34214606c5ff7f9f6f0530c0edf7ce30d12ff6ac973fda861e61c92e99f4f607)
  - Bazelisk version attempted: v1.19.0 (downloaded in step 6)

- Missing packages or files
  - Not mentioned; error indicates a syntax issue with the here-document, not a missing file.

- Notes
  - The failure is due to a malformed here-document in the Dockerfile (line 31), causing a syntax error near the '(' and an unexpected end-of-file delimiter.

Summary (under 1500 chars):

- Exact error message and exit code:
  ERROR: Fetching target dependencies for deps(//...) encountered an error: Evaluation of query "deps(//...)" failed: preloading transitive closure failed: no such target '@@local_cuda//:cuda_runtime_static': target 'cuda_runtime_static' not declared in package '' defined by /root/.cache/bazel/_bazel_root/eab0d61a99b6696edb3d2aff87b585e8/external/local_cuda/BUILD
  Exit code: 2

- Failing command/step:
  [7/9] RUN bazelisk fetch //...     && bazelisk build //app/blitzar:blitzar --define=use_cuda=false

- Missing packages or files mentioned:
  - Missing target: cuda_runtime_static in external/local_cuda/BUILD (target '@@local_cuda//:cuda_runtime_static' not declared)

- Version mismatch information:
  - Bazel version being pulled: Bazel 7.1.2 (bazel-7.1.2-linux-x86_64)
  - Bazelisk version: 1.19.0
  - Context: CUDA-related Bazel rules failing due to missing/undeclared cuda_runtime_static in local_cuda, suggesting a mismatch or misconfiguration between the CUDA rule version and the local_cuda repository.

- Failing step (Dockerfile step 7/9):
  RUN bazelisk fetch //...     && bazelisk build //app/blitzar:blitzar --define=use_cuda=false

- Exact error message and exit code:
  ERROR: Fetching target dependencies for deps(//...) encountered an error: Evaluation of query "deps(//...)" failed: preloading transitive closure failed: no such package '@@[unknown repo 'local_cuda' requested from @@]//': The repository '@@[unknown repo 'local_cuda' requested from @@]' could not be resolved: No repository visible as '@local_cuda' from main repository
  ... (the process then exits with) exit code: 2

- Missing packages/files / repository issue:
  - The build cannot resolve the repository local_cuda: "no such package '@@[unknown repo 'local_cuda' requested from @@]//'" and "The repository '@@[unknown repo 'local_cuda' requested from @@]' could not be resolved: No repository visible as '@local_cuda' from main repository"
  - This indicates the local_cuda repository is not defined/visible in WORKSPACE for the Bazel fetch/build.

- Version information observed:
  - Bazel version being downloaded via Bazelisk: Bazel 7.1.2 (https://releases.bazel.build/7.1.2/release/bazel-7.1.2-linux-x86_64...)
