u-config

  • pkg-config-linux-amd64 is a more optimized target compared to the more portable pkg-config target or manually building main_posix.c
  • According to “personal” “micro”benchmarks, u-config is around 1.5x faster than pkgconf with a slightly smaller footprint
  • Does not build with LTO enabled as upstream explicitly disables LTO
  • We can use OPT="$CFLAGS" instead of LINUX_CFLAGS="$CFLAGS" but then we’d lose access to PIE..
  • Does not support PKG_CONFIG_SYSROOT_DIR but seems to set pc_sysrootdir to / in src/u-config.c by default
  • rad still needs to set PKG_CONFIG_SYSROOT_DIR in cross as we can’t guarantee what pkg-config implementation the host is using
  • Requires pkg.m4 from pkgconf; otherwise several packages (eiwd, libarchive and make) will not build
