Today, I followed Build from Source to compile gRPC on ArchLinux:
$ git clone -b $(curl -L https://grpc.io/release) https://github.com/grpc/grpc
$ cd grpc
$ git submodule update --init
$ make
Current gRPC‘s release version is v1.4.x:
$ curl -L https://grpc.io/release
v1.4.x
The build flow will generate the errors like this:
......
src/core/lib/support/murmur_hash.c: In function ‘gpr_murmur_hash3’:
src/core/lib/support/murmur_hash.c:79:10: error: this statement may fall through [-Werror=implicit-fallthrough=]
k1 ^= ((uint32_t)tail[2]) << 16;
~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~
src/core/lib/support/murmur_hash.c:80:5: note: here
case 2:
^~~~
src/core/lib/support/murmur_hash.c:81:10: error: this statement may fall through [-Werror=implicit-fallthrough=]
k1 ^= ((uint32_t)tail[1]) << 8;
~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~
src/core/lib/support/murmur_hash.c:82:5: note: here
case 1:
^~~~
cc1: all warnings being treated as errors
......
After referring Fix warnings with GCC 7, I finally make the compilation successful. To facilitate others to build gRPC v1.4.x source code on ArchLinux, I create a patch, and hope it can help others.
P.S.
(1) You should fallback to OpenSSL 1.0. Please refer here:
PKG_CONFIG_PATH=/usr/lib/openssl-1.0/pkgconfig make
Otherwise you may encounter following errors:

(2) You may need to change installation directory from /usr/local to /usr:
make prefix=/usr install
This lets you process pkg-config path easily.
