From 981cefe8d3f4f73461789713726a9658498a5f14 Mon Sep 17 00:00:00 2001 From: Erik Schnetter Date: Sun, 17 Jan 2016 10:54:12 -0500 Subject: [PATCH] Make Boost build with MPI on OS X Boost does not build on OS X with either gold or binutils. The gold linker does not exist on Darwin, and binutils on Darwin provides an assembler that doesn't work for Boost. - Introduce a variant that specifies whether to build with binutils, defaulting to true for backward compatibility - Auto-detect whether we build on Darwin; in this case, set the gold and binutils variant defaults to false - Clean up configure flags for as and ld --- var/spack/packages/boost/package.py | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/var/spack/packages/boost/package.py b/var/spack/packages/boost/package.py index 3427b74ad6..894af9edd1 100644 --- a/var/spack/packages/boost/package.py +++ b/var/spack/packages/boost/package.py @@ -1,5 +1,8 @@ from spack import * +import os +import sys + class Boost(Package): """Boost provides free peer-reviewed portable C++ source libraries, emphasizing libraries that work well with the C++ @@ -127,6 +130,16 @@ def determine_b2_options(self, spec, options): '--layout=tagged']) def install(self, spec, prefix): + # On Darwin, Boost expects the Darwin libtool.
