#
# Caveats:
#
#    This Makefile assumes that it is located in gdp/lang/js/gdpjs/ ,
#    where gdp/ is a GDP Git local repository.  See GDPROOT and
#    the (unstructured) -I..'s below.
#
#    It will not force a re-build of the system up in gdp/ .
#    gdp/ must be re-built and kept up to date separately.
#
#    Products of the build:
#      1) *.o and *.a are left in the current directory
#      2) the dynamic library, libgdpjs.so.<<major>>.<<minor>> is moved
#      to gdpjs/libs/ and variously named copies are sym linked to it there.
#    Note, some of the various dynamic library sym linked files have
#    version information within their file names.
#
#    Yes, this Makefile is not as clean, structured, and parameterized
#    as it could be!


# External makefile targets below: all, clean
# TBD: provide a test/ sub-directory.

# Mac and Linux have different naming conventions, so we
# conditionalize a script instead of having rules.  If we ran
# configure somewhere, then we could avoid this, but configure has its
# own set of complexities.  This rule generates the libgdpjs shared
# library and then creates links in the libs directory that include
# the gdp and ep shared libraries.  We need to have all three
# libraries so that we can build a npm package.  Unfortunatley, RHEL
# and Ubuntu seem to have different versioning conventions, so we need
# both libxx-n.m.so and libxx.so.n-m.
#
# libcrypto and libssl are different under RHEL vs. Ubuntu, so
# we have different shared libraries for RHEL.
#
# There is no need to ship the libep shared library with the GDP/JS
# interface because libgdp and libgdpjs have linked with the libep
# static library.
