pkg-config 命令

常用示例

说明

pkg-config retrieves compiler and linker flags needed to build software against installed libraries. It reads metadata from .pc files that libraries install, providing the correct include paths, library paths, and link flags. Build systems like autotools, CMake, and Meson use pkg-config to locate libraries portably. The --cflags flag returns compiler flags (include paths), --libs returns linker flags, and --modversion shows the installed version. Version constraints can be checked with --atleast-version.
