11-11: Use modern CMakefind_packagefor zlib
Linking raw-lzbypasses CMake’s package management. It’s more robust to use:find_package(ZLIB REQUIRED) target_link_libraries(git PRIVATE ZLIB::ZLIB)dockerfiles/cpp-23.Dockerfile (2)
15-18: Reduce image size by cleaning up CMake artifacts
After extraction, the downloaded tarball remains in the layer, inflating the final image. Consider this diff:RUN wget --progress=dot:giga https://github.com/Kitware/CMake/releases/download/v3.30.5/cmake-3.30.5-Linux-x86_64.tar.gz && \ tar -xzvf cmake-3.30.5-Linux-x86_64.tar.gz && \ mv cmake-3.30.5-linux-x86_64/ /cmake + rm cmake-3.30.5-Linux-x86_64.tar.gzOptionally combine with other RUN steps to minimize layers.
36-38: Consolidate cache move steps to reduce Docker layers
These threeRUNinstructions can be merged into one to streamline the build:-RUN mkdir -p /app-cached -RUN if [ -d "/app/build" ]; then mv /app/build /app-cached; fi -RUN if [ -d "/app/vcpkg_installed" ]; then mv /app/vcpkg_installed /app-cached/build; fi +RUN mkdir -p /app-cached && \ + [ -d "/app/build" ] && mv /app/build /app-cached && \ + [ -d "/app/vcpkg_installed" ] && mv /app/vcpkg_installed /app-cached/buildstarter_templates/cpp/code/.gitignore (1)
54-54: Suggestion: Explicit directory ignore syntax
To make it clear you intend to ignore thebuilddirectory (not a file namedbuild), consider adding a trailing slash:- build + build/

16-16: Entry point reference updated
Nice update changing the entry point fromsrc/Server.cpptosrc/main.cpp. This now correctly directs users to the actual implementation file.
30-32: Consistent correction of entry point
The second mention has also been updated tosrc/main.cpp, ensuring both sections reference the same file.compiled_starters/cpp/README.md (2)
16-16: Approve documentation update for correct entry point
The reference tosrc/main.cppis now accurate and aligns with the actual project structure.
32-32: Approve documentation update for correct entry point
The note correctly points users tosrc/main.cppfor stages 2 and beyond.dockerfiles/cpp-23.Dockerfile (2)
2-2: Approve updated GCC base image
Moving togcc:14.2.0-bookwormkeeps the build environment up-to-date.
5-5: Approve cache-busting ENV variable
CODECRAFTERS_DEPENDENCY_FILE_PATHSis properly added to force rebuilds when dependencies change.solutions/cpp/01-gg4/code/.gitignore (1)
4-55: Approve expanded and reorganized.gitignore
The new categories and patterns comprehensively cover object files, linker outputs, libraries, shared objects, executables, debug symbols, kernel module artifacts, and thebuild/vcpkg_installeddirectories. This brings consistency with other C++ templates and starters.starter_templates/cpp/code/.gitignore (6)
4-9: Approve: Expanded object file ignore patterns
Great additions to the object files section—kernel module files (*.ko) and ELF binaries (*.elf) are now covered alongside the existing*.o.
10-13: Approve: Linker output ignore entries
The new patterns for.ilk,.map, and.expfiles will correctly suppress common linker artifacts.
19-24: Approve: Library file ignore patterns
Including static (*.a), import (*.lib), and archive (*.la,*.lo) files in the libraries section broadens coverage of build outputs.
25-28: Approve: Shared object versioning patterns
Adding*.so.*and continuing to ignore.dlland.dylibcovers both Windows and UNIX shared‐library variants and their versioned counterparts.
35-38: Approve: Architecture‐specific executable patterns
Patterns for*.i*86,*.x86_64, and*.hexfiles capture additional raw binaries—nice catch for low‐level targets.
39-44: Approve: Debug symbol and metadata files
The inclusion of*.dSYM/,*.su,*.idb, and*.pdbensures IDE and DWARF debug artifacts are ignored.

💡 Verification agent
🧩 Analysis chain
Confirm updated entry point path exists. Verify that src/main.cpp actually replaces src/Server.cpp in the starter template directory.
🏁 Script executed:
#!/bin/bash
# Verify the presence of the new user_editable_file in the starter template
if [ ! -f starter_templates/cpp/src/main.cpp ]; then

Fix the entry point path in config.yml
The user_editable_file in starter_templates/cpp/config.yml currently points to src/main.cpp, but the actual file lives under code/src/main.cpp. Update the path to match the template layout:
• File: starter_templates/cpp/config.yml
user_editable_file: src/main.cpp
-# should point to where main.cpp really lives
+user_editable_file: code/src/main.cppCommittable suggestion skipped: line range outside the PR's diff.

🛠️ Refactor suggestion
Fix word-splitting risk by quoting dirname invocation
Removing quotes around $0 can break path resolution when the script lives in a path containing spaces or special characters.
Apply this diff to restore safe quoting:
-exec $(dirname $0)/build/git "$@"
+exec "$(dirname "$0")/build/git" "$@"📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🛠️ Refactor suggestion
Reinstate quoting to prevent word splitting
The unquoted dirname $0 risks splitting on whitespace or globbing. Quoting ensures reliable path resolution across all environments.

@andy1li let's change the starter template to keep the quoting btw - this was correct
