# Host side dependencies... Probably nowhere near complete

# all it produces is -lsolv, the fact that it's taking stuff from the
# host doesn't have serious drawbacks, so we can leave it for now.
# FIXME Host pyudev is required to make lvm2's configure script happy,
# but it should really check the sysroot instead.
# FIXME rrdtool looks for host pangocairo headers, but really needs
# target headers
# FIXME glibmm and similar rarely used cruft is required by enchant2, which
# in turn is required by rpmlint. Trim down rpmlint at some point?

# Some notes for the build order (and reasons for packages you
# might not expect to see in a core package set):
# - systemd, expat -> dbus
# - dbus -> rpm, systemd
# - libtirpc, libnsl -> pam
# - libbpf, tmp2-tss, libidn2, cryptsetup, gnutls, libxkbcommon, glib2.0 -> systemd
# - gmp, libunistring, nettle, libtasn1, brotli, p11-kit -> gnutls
# - wayland -> libxkbcommon
# - libffi -> p11-kit
# - json-c, curl, openssl -> tpm2-tss
# - libssh -> curl
# - lksctp-tools -> openssl
# - libmicrohttpd -> elfutils (libelf) -> libbpf -> systemd
# - libidn2 -> systemd
# - libpng -> qrencode -> systemd
# - cracklib -> libpwquality -> systemd
# - x11-proto-devel -> libxau -> libxkbfile -> xkbcomp -> libxcb -> libx11 -> dbus
# Because of the way we package LLVM to avoid cyclic dependencies
# (Vulkan headers and friends inside SPIR-V), we also need half a
# GUI stack:
# - vulkan-headers, vulkan-loader -> LLVM
# - libXrender, libXext -> libXrandr -> vulkan-loader
# - x11-xtrans-devel is a dependency of libx11
# - libxau is a dependency of libxcb
#
# Anything in the list after llvm is there to fulfill runtime dependencies of the
# packages built before. If you want to build the minimal possible system, you can
# leave some of those out and remove a couple of subpackages.
