gRPC error while installing in OSX el captain

[Bugsfunny]

I installed grpc using the below commands : 

git clone -b $(curl -L http://grpc.io/release) https://github.com/grpc/grpc
cd grpc
git checkout -b 1.2.0
git submodule foreach git clean -xfd
git submodule update --init
cd third_party/protobuf
./autogen.sh
./configure
make -j2
sudo make install
cd ../cares/cares/
./buildconf
./configure
make -j2
make ahost adig acountry
make install
cd ../..
git clean -xfd
make -j2          (I get the below error while executing this command)
sudo make install      (did not execute this command)

Plz help me with this..

My guess is that you have an older copy of protobuf installed on the system somewhere. Can you manually search and remove older protobuf libraries?

Thanks for replying..

I tried deleting all the files that are related to protobuf and grpc in all the bin and lib folders and tried installing it again.

1) When I install grpc first and then protobuf.. I'm able to install it without any errors... But i'm getting the below error while running the helloworld program in cpp exmaples.

2) When I install protobuf first and then grpc i'm getting the same error which i first posted in this thread (during executing make command in grpc directory ).

Did you found a reason for this error? I am stuck at the same point with the same error as yours.

[Martin Scholz]

I know this is an old thread, but I'm stucking with same at the moment. What i did. Build gRPC with CMake on Mac. No failures. Then linking libs to my project and when trying to build get the following

The same project with libs build on windows with CMake is working there. So it seems to be a problem with clang on Mac. Is there any solution for this. It seems there are many old threads on github, but none with a solution.

Thx.

[Martin Scholz]

Sorry, got it. Forgot to build gRPC with OpenSSL like i do on windows.

[Justin Pojol Chang]

martin, I am still getting your exact same issue when trying to build a separate project with grpc on mac. What did you mean build gRPC with OpenSSL and how do I do that?

[Seyed Mahdi Mousavi]

I faced same issue just like you. I noticed that error reference is Channel. So I tried to add grpc++_unsecure and grpc_unsecure and problems gone.

[Seyed Mahdi Mousavi]

I mean grpc++_unsecure and grpc_unsecure libraries from grpc
