Subject: [PATCH] setup.py: Do not mix C and C++ compiler options
|
|
EXTRA_ENV_COMPILE_ARGS is used both with CC and CXX
|
so using -std=c++11 or -std=gnu99 together will cause
|
build time errors espcially with clang
|
|
Keep '-std=c++11' to fix native build error
|
with old gcc (such as gcc 5.4.0 on ubuntu 16.04), for clang
|
we will remove them through GRPC_PYTHON_CFLAGS at do_compile
|
in bb recipe.
|
|
While export CC="gcc ", cc_args is None, it will
|
cause subprocess.Popen always return 1. On centos 8, if you don't
|
install package libatomic, there will be a native build error
|
`cannot find /usr/lib64/libatomic.so.1.2.0'.
|
|
Add no harm '-g' to cc_args if cc_args is empty.
|
|
Upstream-Status: Inappropriate [oe specific]
