From 30ce693621d61efb8596503a0da212077a8c4daa Mon Sep 17 00:00:00 2001 From: Thomas Bechtold Date: Thu, 24 May 2018 17:12:13 +0200 Subject: [PATCH] Allow building the python module with system openssl When building the python module and using the new GRPC_PYTHON_BUILD_SYSTEM_OPENSSL env variable, the third party boringssl code is not compiled. Instead, the openssl shared library installed on the system is used during runtime. This is useful for distributions who don't want to include code copies but use shared libraries instead. --- setup.py | 17 +++++++++++++++-- 1 file changed, 15 insertions(+), 2 deletions(-) diff --git a/setup.py b/setup.py index 99d1a1c504e..3a5ed56c641 100644 --- a/setup.py +++ b/setup.py @@ -35,7 +35,7 @@ PY3 = sys.version_info.major == 3 PYTHON_STEM = os.path.join('src', 'python', 'grpcio') CORE_INCLUDE = ('include', '.',) -BORINGSSL_INCLUDE = (os.path.join('third_party', 'boringssl', 'include'),) +SSL_INCLUDE = (os.path.join('third_party', 'boringssl', 'include'),) ZLIB_INCLUDE = (os.path.join('third_party', 'zlib'),) CARES_INCLUDE = ( os.path.join('third_party', 'cares'), @@ -84,6 +84,12 @@ # present, then it will still attempt to use Cython.
