Summary:
- Failing command/step: RUN bazel build //app/blitzar:blitzar (builder 6/6)
- Exit code: 1
- Exact error messages (preserved):
  - Auto-Configuration Error: Cannot find gcc or CC (clang); either correct your path or set the CC environment variable
  - ERROR: no such package '@@bazel_tools~cc_configure_extension~local_config_cc//':
  - Auto-Configuration Error: Cannot find gcc or CC (clang); either correct your path or set the CC environment variable
  - ERROR: /workspace/app/blitzar/BUILD:6:14: //app/blitzar:blitzar depends on @@bazel_tools~cc_configure_extension~local_config_cc//:cc-compiler-k8 in repository @@bazel_tools~cc_configure_extension~local_config_cc which failed to fetch. no such package '@@bazel_tools~cc_configure_extension~local_config_cc//':
  - Analysis of target '//app/blitzar:blitzar' failed; build aborted: Analysis failed
- Failing step details:
  - The build progressed to Bazel-based compilation in the image, but Bazel could not locate a C/C++ compiler in PATH (gcc/clang or CC env var).
  - It then failed to fetch the cc_configure_extension local_config_cc rule, causing the target //app/blitzar:blitzar to be unbuildable.
- Missing packages/files mentioned:
  - No explicit missing file names; the log centers on “Cannot find gcc or CC (clang)” indicating the compiler is not available in the build environment PATH.
- Version information mentioned:
  - Bazel binary being downloaded: bazel-7.1.2-linux-x86_64
  - Bazelisk wrapper: v1.15.0
  - Context also shows extensive apt-get install activity earlier, but the failure is specifically due to the Bazel auto-configuration not finding a compiler, not a missing OS package at this point.

Notes:
- Root cause: absence of a usable C/C++ compiler in the Bazel toolchain path (ENV CC or PATH).
- Actionable follow-up: ensure gcc or clang is installed and visible in PATH (or set CC appropriately) before running bazel build in this Docker image.

Summary of Docker build error

- Failing step (command): [builder 6/6] RUN bazel build //app/blitzar:blitzar
- Exact error message and exit code:
  - Auto-Configuration Error: Cannot find gcc or CC (clang); either correct your path or set the CC environment variable
  - Exit code: 1
- Key missing packages/files / issues:
  - Cannot find gcc or CC (clang); path issue or CC env var not set
  - Unable to fetch package //:bazel_tools~cc_configure_extension~local_config_cc due to the above, i.e. no such package '@@bazel_tools~cc_configure_extension~local_config_cc//'
- Context and relevant details:
  - Build runs Bazel during image build (base is Ubuntu 22.04)
  - The failure occurs during the fetch/auto-configuration step for the local CC toolchain (cc_configure_extension)
- Version/mismatch notes:
  - No explicit version mismatch information provided. Bazel attempted to fetch its components, but the failure is due to missing compiler in PATH (not a version conflict).

Failing step

Exact error messages and exit code
- ERROR: /workspace/WORKSPACE:50:1: name 'register_detected_cuda_toolchains' is not defined

Missing packages or files mentioned
- head: cannot open '/etc/ssl/certs/java/cacerts' for reading: No such file or directory

Version/mismatch information
- Bazel download reference: "Downloading https://releases.bazel.build/7.1.2/release/bazel-7.1.2-linux-x86_64..." ( Bazel 7.1.2 )
- Bazelisk wrapper used: "curl -fsSL ... bazelisk-linux-amd64" (Bazelisk v1.15.0)

Notes
- The errors indicate Bazel cannot load CUDA rules because the repository @rules_cuda is not visible, stemming from the undefined register_detected_cuda_toolchains in WORKSPACE. This is a follow-on to the initial error, not an isolated missing file.

- 19.28 ERROR: Analysis of target '//app/blitzar:blitzar' failed; build aborted

What failed (missing packages/files) and context:
- Root cause: Bazel cannot find a C/C++ compiler in PATH (gcc or clang), triggering an auto-configuration failure for the cc_configure_extension local_config_cc.
- Related fetch error: Cannot fetch the cc_configure_extension local_config_cc package used by //app/blitzar:blitzar.
- BUILD reference: /workspace/app/blitzar/BUILD:6:14 depends on the cc_configure extension package that could not be fetched.

Version/stack notes:
- Bazel download attempted: Bazel 7.1.2 (bazelisk-linux-amd64), via Bazelisk v1.15.0.
- The runtime environment shows GCC/G++ components being installed (gcc-11, gcc-11-base, gcc, libstdc++6, etc.) during apt-get, with both gcc-11 and gcc-12-base present, indicating a mixed toolchain. Despite this, Bazel still cannot locate a compiler in PATH for the cc_configure step.

Summary of Docker build error (preserve actionable details)

- Failing step (command/step):
  - [6/6] RUN bazel version &&     bazel fetch //app/blitzar:blitzar || true &&     bazel build //app/blitzar:blitzar

- Exact error message(s) and exit code:
  - Exit code: 1
  - Auto-Configuration Error: Cannot find gcc or CC (clang); either correct your path or set the CC environment variable
  - ERROR: no such package '@@bazel_tools~cc_configure_extension~local_config_cc//': 
  - ERROR: /work/app/blitzar/BUILD:6:14: //app/blitzar:blitzar depends on @@bazel_tools~cc_configure_extension~local_config_cc//:cc-compiler-k8 in repository @@bazel_tools~cc_configure_extension~local_config_cc which failed to fetch. no such package '@@bazel_tools~cc_configure_extension~local_config_cc//': 

- Context about the failure:
  - Bazelisk version: v1.22.0
  - Build label: 7.1.2
  - Build target: //app/blitzar:blitzar

- Missing packages/files mentioned:
  - Root cause appears to be missing/undetectable C/C++ compiler in PATH for Bazel: “Cannot find gcc or CC (clang)”; Bazel then cannot fetch the cc_configure_extension, leading to the “no such package” error.

- Version-related notes:
  - Bazel 7.1.2 was detected; Bazelisk reports version v1.22.0.
  - No explicit version mismatch is shown beyond the Bazel/Bazelisk versions in use.

Exact error messages observed (preserve exact wording where shown):
- Auto-Configuration Error: Cannot find gcc or CC (clang); either correct your path or set the CC environment variable
- ERROR: no such package '@@bazel_tools~cc_configure_extension~local_config_cc//':

- Auto-Configuration Error: Cannot find gcc or CC (clang); either correct your path or set the CC environment variable
- ERROR: Analysis of target '//app/blitzar:blitzar' failed; build aborted
- Information: Build did NOT complete successfully

Missing packages/files mentioned (root cause hints):
- Compiler not found: Cannot find gcc or CC (clang); environment variable CC not set
- Bazel cc_configure_extension local_config_cc fetch failed due to missing compiler
- No such package for cc_configure_extension~local_config_cc

Version/compatibility details:
- Bazel version being used: bazel 7.1.2 (downloaded and run via /usr/local/bin/bazel)
- Bazelisk version: v1.15.0
- Context suggests a mismatch between required C/C++ toolchain and environment, despite extensive apt-get installs of various gcc/g++ components during the build.

Failing step
- Builder step: RUN /usr/local/bin/bazel build //app/blitzar:blitzar
- Docker build exit code: 1

Exact error message(s) and context
- Bazel error 1:
  ERROR: /root/.cache/bazel/_bazel_root/1e0bb3bee2d09d2e4ad3523530d3b40c/external/local_cuda/BUILD: no such target '@@local_cuda//:compiler_deps': target 'compiler_deps' not declared in package '' defined by /root/.cache/bazel/_bazel_root/1e0bb3bee2d09d2e4ad3523530d3b40c/external/local_cuda/BUILD
- Bazel error 2 (referenced by the CUDA toolchain):
  ERROR: /root/.cache/bazel/_bazel_root/1e0bb3bee2d09d2e4ad3523530d3b40c/external/local_cuda/toolchain/clang/BUILD:26:15: no such target '@@local_cuda//:compiler_deps': target 'compiler_deps' not declared in package '' defined by /root/.cache/bazel/_bazel_root/1e0bb3bee2d09d2e4ad3523530d3b40c/external/local_cuda/BUILD and referenced by '@@local_cuda//toolchain/clang:clang-local'
- Bazel outcome:
  Analysis of target '//app/blitzar:blitzar' failed; build aborted: Analysis failed

Missing packages or files mentioned
- Missing Bazel target: compiler_deps in the external CUDA Bazel repository (external/local_cuda). The BUILD files local_cuda/BUILD and local_cuda/toolchain/clang/BUILD reference a target that is not declared.

Version/environment details that matter
- Bazel version used: 7.1.2 (downloaded as bazel 7.1.2 and invoked via /usr/local/bin/bazel)
- Context indicates a Bazel external_cuda rule mismatch or missing target in the CUDA repo, not a compile error in app/blitzar itself. This often points to version/compatibility issues between Bazel rules and the CUDA external repo.

  - None mentioned. The error is a Bazel configuration issue (nogpu config not defined in any .rc file), not a missing package/file.

- Version mismatch info
  - Bazel version: 7.1.2 (downloaded by bazelisk v1.15.0)
  - Bazelisk version: 1.15.0
  - Base image/OS: Ubuntu 22.04 (jammy)
  - No explicit version mismatch noted beyond the config error; the failure is due to an undefined Bazel config value.

  - ERROR: Error computing the main repository mapping: error loading package 'external': Failed to parse WORKSPACE file
- Exit code: 1

- Failing command/step:
  - [builder 8/8] RUN /usr/local/bin/bazel build //app/blitzar:blitzar

- Missing packages or files mentioned:
  - None explicitly missing; the failure is a syntax error in the WORKSPACE file (line 46) that prevents Bazel from parsing external repositories.

- Version mismatch info (or relevant version details):
  - Bazel version 7.1.2 was downloaded and used (bazel 7.1.2).
  - The failure occurs after Bazel starts the local server during the build step; no concrete version mismatch is indicated beyond the Bazel version observed.
