# Firehose Makefile fragment
# This Makefile fragment is used to build GASNet conduits 
# it is not meant to be used directly 
#
# To use in a conduit Makefile.am, set fh_type to either "region" or
# "page" (no quotes, no whitespace) and then include this fragment.
# Example:
#    fh_type=region
#    include $(top_builddir)/other/firehose/firehose.mak
#
# This fragment defines the following variables for use
# in the corresponding CONDUIT_* variables.  For instance,
# one should include $(fh_sourcelist) in CONDUIT_SOURCELIST
#
# fh_sourcelist     - C files to build normally
# fh_extralibcflags - CFLAGS needed for firehose headers
# fh_extraheaders   - firehose header(s) to install from firehose directory
# fh_privheaders    - firehose header(s) not to install from conduit directory
# fh_extradeps      - dependencies on firehose .c and .h files
# fh_special_objs   - firehose .o files with "abonormal" build requirements
#
# fh_{src,bld}dir are also set, but probably aren't needed outside this fragment
