# Linux build for sony-head-tracker.
# The cross-platform CMake build (CMakeLists.txt) is the source of truth used by
# CI and by the macOS/Windows builds; this Makefile is a dependency-free Linux
# convenience that produces build/sony-head-tracker with the same sources as the
# CMake `if(LINUX)` target. See docs/LINUX.md.
#
#   make            build the CLI
#   make test       build + run the Linux test suite
#   make gui        run the GTK GUI against the built CLI
#   make install-gui   add the GUI to your application menu
#   make portable   build for redistribution (see PORTABLE below)
#   make clean
#
# PORTABLE=1 links libstdc++ and libgcc statically. Distribution packages should
# NOT use it (they want the shared libraries), but a binary shipped to arbitrary
# systems does: std::format pulls in GLIBCXX_3.4.35 and 3.4.36 symbols, and a
# system whose libstdc++ is older then refuses to load the binary at all. The
# most important case is SteamOS 3.8 on the Steam Deck, which caps at
# GLIBCXX_3.4.34 (its glibc 2.41 is new enough, so only the C++ runtime is the
# problem). Three std::format symbols are the entire reason, so this one flag is
# far cheaper than rewriting every std::format call site.

# c++ rather than g++: resolves to g++ on glibc distros and to clang++ where no
# GCC is shipped (Chimera Linux). Needs g++ 13+ or clang 16+ for std::format.

PYTHON   ?= python3
