# flux-core's own -Werror build already disables -Wstrict-aliasing,

# hwloc-ohpc's SONAME (libhwloc.so.15) matches the base distro's own
# hwloc-libs, and this package installs under /usr, not %{OHPC_HOME},
# so it falls outside ohpc-filesystem's fileattrs-based dependency
# coloring (same root cause as flux-pmix's libpmix.so situation, and
# the same fix already applied to flux-core.spec). Without this,
# rpmbuild's auto-Requires would be a bare libhwloc.so.15()(64bit),
# satisfiable by either package. Filter it out; the explicit
# "Requires: hwloc-ohpc" below is the only way this dependency is
# meant to be expressed.

%description
Fluxion is a graph-based scheduler for the Flux resource manager
framework. It replaces flux-core's default first-come-first-served
scheduler with a more sophisticated one that supports configurable
queuing policies and matches resource requests against a graph model
of the cluster's hardware.

It installs two modules loaded by the flux broker:
  - sched-fluxion-resource, which matches resource requests to
    available resources using Fluxion's graph-based algorithm
  - sched-fluxion-qmanager, which manages one or more prioritized job
    queues

This package requires flux-core (>= 0.78.0, the minimum version
Fluxion's own build enforces) to already be installed, since its
CMake-based build discovers flux-core via pkg-config and by running
the installed flux binary.

%build
# hwloc-ohpc, not the base distro's hwloc-devel; same rationale as
# flux-core.spec. Purge first so a build host's sticky default module
# collection (e.g. from lmod-defaults-*-ohpc) can't silently swap in
# an OpenHPC compiler toolchain instead of the system compiler this
# still builds with.
module purge
module load hwloc
export PKG_CONFIG_PATH="${HWLOC_LIB}/pkgconfig:${PKG_CONFIG_PATH}"

# hwloc-ohpc's library lives outside the default runtime linker
# search path; without an RPATH, the built binaries would only find
# libhwloc.so at run time if "module load hwloc" happened to already
# be active, which nothing in a real deployment does. CMake picks up
# LDFLAGS for its initial linker flags the same way autotools does.
export LDFLAGS="${LDFLAGS} -Wl,-rpath,${HWLOC_LIB}"

# flux-core's own -Werror build sets -Wno-strict-aliasing; same
# rationale as flux-core.spec's CFLAGS override.
#
# CMAKE_INSTALL_SYSCONFDIR is forced explicitly rather than relying
# on GNUInstallDirs' "prefix is exactly /usr" auto-absolutizing
# convention, which is what left the etc/rc1.d, etc/rc3.d and
# etc/modprobe install() rules writing under a path %files never
# found. ENABLE_DOCS=On turns the "Try find sphinx-build, silently
# skip docs if not found" default into a hard failure instead, so a
# missing man page shows the real reason instead of nothing.

# lib64, since guessing that wrong is exactly what broke this here.
