When optimizing application performance, carefully select compiler flags based on your optimization goals. For size-critical applications or accurate size measurements, use -Oz to prevent aggressive inlining that can distort metrics. Additionally, implement compiler caching with tools like ccache to significantly improve build times in development and CI environments.
For CMake-based projects, enable ccache with:
# For direct CMake invocation
cmake . -B build -G Ninja -DCMAKE_CXX_COMPILER_LAUNCHER=ccache -DCMAKE_BUILD_TYPE=Release
# For npm/cmake-js projects
npm config set cmake_CMAKE_CXX_COMPILER_LAUNCHER ccache
When analyzing binary size with tools like Bloaty, ensure you’re comparing equivalent architectures by isolating specific targets:
# Example extracting ARM64 binary from multi-architecture framework
cp MapLibre.xcframework/ios-arm64/MapLibre.framework/MapLibre MapLibre_arm64
These practices ensure both efficient development cycles and optimized production artifacts.
