libtirpc dependency

[ivan-pi]

In the HemePure Spack build we had to add:

    def setup_build_environment(self, env):
                env.prepend_path('CPATH', self.spec['libtirpc'].prefix.include.tirpc)
                env.append_flags('LDFLAGS', '-ltirpc')

It seems the RPC library is not available by default on some systems, nor are modules commonly available. The spack info command shows it can be obtained from Sourceforge:

~/HemePure-GPU/src/build$ spack info libtirpc
AutotoolsPackage:   libtirpc
