Summary of Docker build error

- Failing step (exact step): [builder 9/9] RUN bash -lc 'cat > backtracking/build/backtracking << "EOF"\n#!/bin/sh\necho Backtracking OK.\nEOF\nchmod +x backtracking/build/backtracking'

- Exact error message and exit code:
ERROR: process "/bin/sh -c bash -lc 'cat > backtracking/build/backtracking << "EOF"\n#!/bin/sh\necho Backtracking OK.\nEOF\nchmod +x backtracking/build/backtracking'" did not complete successfully: exit code: 1

- Failing command/line from Dockerfile:
RUN bash -lc 'cat > backtracking/build/backtracking << "EOF"\n#!/bin/sh\necho Backtracking OK.\nEOF\nchmod +x backtracking/build/backtracking'

- Error details observed in logs:
1) bash: line 1: warning: here-document at line 1 delimited by end-of-file (wanted `EOFn#!/bin/shnecho')
2) cat: Backtracking: No such file or directory
3) cat: OK.nEOFnchmod: No such file or directory
4) cat: +x: No such file or directory

- What the logs indicate about missing files/packages:
- No missing packages or system files mentioned.
- The errors indicate problems with the here-document not creating/writing the target file: the path backtracking/build/backtracking could not be created/written due to the misparsed here-doc. Directory backtracking/build existed (from a prior step), but the cat redirection failed.

- Version mismatch information:
- None reported as a mismatch.
- Contextual version references in the run include:
  - Base image: ubuntu:jammy-20260509
  - GCC/Clang toolchain shown: GNU 11.4.0
- Warnings about CMake (e.g., missing project() and cmake_minimum_required) are present but not version mismatches.

Notes:
- The failure is solely due to the here-document being misinterpreted in the RUN command, not due to missing dependencies. The fix would involve ensuring the here-doc is correctly formatted so the file backtracking/build/backtracking is created and made executable.

Summary (under 1500 chars)

- Exact error message and exit code
  - bash: line 1: warning: here-document at line 1 delimited by end-of-file (wanted `EOFn#!/bin/shnecho')
  - cat: Backtracking: No such file or directory
  - cat: OK.nEOFnchmod: No such file or directory
  - cat: +x: No such file or directory
  - ERROR: failed to build: failed to solve: process "/bin/sh -c mkdir -p backtracking/build &&     bash -lc 'cat > backtracking/build/backtracking << \"EOF\"\\n#!/bin/sh\\necho Backtracking OK.\\nEOF\\nchmod +x backtracking/build/backtracking'" did not complete successfully: exit code: 1

- Failing command/step
  - [builder 7/7] RUN mkdir -p backtracking/build &&     bash -lc 'cat > backtracking/build/backtracking << "EOF"\n#!/bin/sh\necho Backtracking OK.\nEOF\nchmod +x backtracking/build/backtracking'

- Missing packages or files mentioned
  - Not a missing package. The failure is due to a here-document syntax/parse issue during file creation:
    - here-document warning and subsequent “No such file or directory” errors indicate the intended file backtracking/build/backtracking could not be created as written by the here-doc command.

- Version mismatch info
  - Base image: ubuntu:jammy-20260509 (sha256:9cff99391df1fa366434d373df9277cfc96f75e6eafe8684d0263b88c9691be2)
  - C/C++ compiler: GNU 11.4.0
  - CMake warnings observed earlier (unrelated to this failure): 
    - No project() command present in CMakeLists.txt
    - No cmake_minimum_required command present
    - Manually-specified variable USE_OPENMP not used by the project

Notes
- The failure occurs at the final build step, not due to missing libraries or tools, but due to incorrect here-doc handling in the RUN command, causing the file backtracking/build/backtracking to not be created.

Summary of Docker build error

- Exact error message and exit code
  - Exit code: 2
  - Errors shown:
    - bash: line 1: warning: here-document at line 1 delimited by end-of-file (wanted `PYn#!/usr/bin/env')
    - bash: -c: line 1: syntax error near unexpected token `('
    - bash: -c: `cat > /usr/local/bin/fibonacci <<"PY"\n#!/usr/bin/env python3\nimport sys\ntry:\n    s = sys.stdin.read().strip()\n    n = int(s) if s else 0\nexcept Exception:\n    n = 0\nA,B = 0,1\nfor _ in range(n):\n    A,B = B,A+B\nprint(A)\nPY\nchmod +x /usr/local/bin/fibonacci'
  - The docker process log ends with: ERROR: process "... did not complete successfully: exit code: 2

- Failing command/step
  - [stage-1 5/6] RUN bash -lc 'cat > /usr/local/bin/fibonacci <<"PY"\n#!/usr/bin/env python3\n... \nPY\nchmod +x /usr/local/bin/fibonacci'

- Missing packages or files mentioned
  - None indicated. The failure is due to an invalid here-document syntax in the shell command, not missing packages or files.

- Version mismatch or related info
  - No explicit version mismatch errors were reported.
  - The log contains normal version strings (e.g., GNU 11.4.0, Ubuntu jammy) and some CMake warnings (e.g., no project() command, no cmake_minimum_required), but no version mismatch errors.

Notes
- The error stems from the here-document used to create /usr/local/bin/fibonacci. The delimiter handling is incorrect in the RUN command, causing a syntax error in the shell. Fix would involve correcting the heredoc syntax (e.g., proper quoting and delimiter usage) in that RUN step.

  - Warning that USE_OPENMP was not used by the project
- Build artifacts: fibonacci binary built at /src/math/build/fibonacci, but the smoke test failed (grep -q 13 returned non-zero).

- Missing packages or files mentioned

Summary (under 1500 chars):

- Failing step: RUN echo 7 | /src/math/build/fibonacci | grep -q 13 (builder 8/8)

- Exact error message and exit code:
  process "/bin/bash -lc echo 7 | /src/math/build/fibonacci | grep -q 13" did not complete successfully: exit code: 1

- Exit code: 1

- Failing command/test details: A smoke test runs the fibonacci binary with input 7 and pipes its output to grep -q 13. The grep command did not find 13 in the output, causing the test to fail with exit code 1.

- Missing packages or files mentioned: None reported. The binary path (/src/math/build/fibonacci) exists and the earlier build steps completed.

- Version/compile environment notes:
  - The build log shows GNU C and CXX compilers identified as GNU 11.4.0.
  - CMake warnings about missing project() and missing cmake_minimum_required were emitted during configuration, but no explicit version mismatch is reported.

Summary (under 1500 chars):

- Exact error message and exit code:
  - /usr/bin/ld: cannot open output file /src/math/build/fibonacci: No such file or directory
  - collect2: error: ld returned 1 exit status
  - exit code: 1

- Failing command/step:
  - [builder 6/6] RUN g++ -std=c++17 -O2 /src/math/fibonacci_cli.cpp -o /src/math/build/fibonacci

- Missing packages or files mentioned:
  - No missing package errors; the linker failed because the output directory does not exist: /src/math/build (cannot open output file). The compiler and toolchain (gcc-11/g++-11) were installed earlier in the build, so the issue is a missing directory, not a missing tool.

- Version mismatch information:
  - The build installed GCC/G++ from Ubuntu jammy (GCC 11.x: gcc-11/g++-11, e.g., 11.4.0-1ubuntu1~22.04.3) as part of the apt-get install in Stage 1. There is no explicit version mismatch reported; the error is due to a missing output directory.

Recommendation to fix:
- Ensure the build output directory exists before linking, e.g., add a step like: mkdir -p /src/math/build
- Alternatively, adjust the output path to an existing directory.
