From d7c46d8c57b763798db16908c671bfb13e8aa9f6 Mon Sep 17 00:00:00 2001 From: Axel Huebl Date: Sat, 27 Jun 2020 13:36:18 -0700 Subject: [PATCH] CUDA: CUDAHOSTCXX Env (#16869) This is a general CMake CUDA language hint to use the CXX compiler has host compiler for NVCC. Seems like a good default since we do not express the CUDA compiler in Spack otherwise yet (e.g. no `self.compiler.cuda` or `self.compiler.cudahostcxx`). --- var/spack/repos/builtin/packages/cuda/package.py | 2 ++ 1 file changed, 2 insertions(+) diff --git a/var/spack/repos/builtin/packages/cuda/package.py b/var/spack/repos/builtin/packages/cuda/package.py index ce1fdf69b9..5fd89cbaa1 100644 --- a/var/spack/repos/builtin/packages/cuda/package.py +++ b/var/spack/repos/builtin/packages/cuda/package.py @@ -77,6 +77,7 @@ class Cuda(Package): depends_on('libxml2', when='@10.1.243:') def setup_build_environment(self, env): + env.set('CUDAHOSTCXX', self.compiler.cxx) if self.spec.satisfies('@10.1.243:'): libxml2_home = self.spec['libxml2'].prefix env.set('LIBXML2HOME', libxml2_home) @@ -84,6 +85,7 @@ def setup_build_environment(self, env): def setup_run_environment(self, env): env.set('CUDA_HOME', self.prefix) + env.set('CUDAHOSTCXX', self.compiler.cxx) def install(self, spec, prefix): if os.path.exists('/tmp/cuda-installer.log'):
