u-config

Build

Section titled “Build”
  • pkg-config-linux-amd64 target is more optimized than the more portable pkg-config target or manually building main_posix.c
  • Does not build with lto and upstream explicitly disables lto as it directly uses raw linux syscalls
  • Override LINUX_CFLAGS and LINUX_LIBS instead of OPT as it allows us to dynamically link instead of the default static link

Package

Section titled “Package”
  • make install target is windows only
  • Provide pkg.m4 from pkgconf as some packages require it (e.g. eiwd, libarchive and make)

Other

Section titled “Other”
  • u-config is around 1.5x faster than pkgconf with a slightly smaller footprint
  • u-config does not support PKG_CONFIG_SYSROOT_DIR but seems to set pc_sysrootdir to / in src/u-config.c by default
  • glaucus still sets PKG_CONFIG_SYSROOT_DIR in cross as we can’t guarantee what pkg-config implementation the host is using
