Error installing/compiling grpc on Ubuntu

Question

I have protobuf compiler version 3.0 and need to install grpc and grpc python plugin. Following the tutorial, I added deb http://http.debian.net/debian jessie-backports main to my sources.list file and did sudo apt-get update and sudo apt-get install libgrpc-dev which returned

Package libgrpc-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'libgrpc-dev' has no installation candidate

So, I decided to compile it from source as mentioned in INSTALL notes and did:

 $ git clone https://github.com/grpc/grpc.git
 $ cd grpc
 $ git submodule update --init
 $ make 
 $ [sudo] make install

However, on the make step, I get

[MAKE]    Generating cache.mk
make: Circular /home/vagrant/grpc2/grpc/libs/opt/libboringssl.a <- /home/vagrant/grpc2/grpc/libs/opt/libboringssl.a dependency dropped.
[C]       Compiling third_party/boringssl/crypto/bio/connect.c
third_party/boringssl/crypto/bio/connect.c: In function 'split_host_and_port':

cc1: all warnings being treated as errors
make: *** [/home/vagrant/grpc2/grpc/objs/opt/third_party/boringssl/crypto/bio/connect.o] Error 1

On switching to the release-0_11 branch, running make results in

[HOSTCXX] Compiling src/compiler/csharp_generator.cc
src/compiler/csharp_generator.cc:47:43: error: 'google::protobuf::compiler::csharp::GetUmbrellaClassName' has not been declared

src/compiler/csharp_generator.cc:237:62: error: 'GetUmbrellaClassName' was not declared in this scope
make: *** [/home/vagrant/grpc2/grpc/objs/opt/src/compiler/csharp_generator.o] Error 1

I can't figure out how to install this. Any help would be appreciated.

For me the issue got fixed after i made change in the file as:

diff --git a/src/compiler/csharp_generator.cc

More specifically, please open the file src/compiler/csharp_generator.cc and replace all references of GetUmbrellaClassName by GetReflectionClassName

Working backwards:

for release-0_11: it looks like you're trying to compile against the most recent protobuf. Since we're both in development right now there's occasional breakage - but grpc does track the version of protobuf it's tested against in third_party/protobuf. Try checking out and installing that version. I filed https://github.com/grpc/grpc/issues/4697 to update to the latest protobuf 3.0 version.

for master from github: which compiler and OS are you using? I recently checked in the boringssl integration work, so it's fresh, and not nearly as battle-tested. I'd like to get it battle-tested. That said, if you do a 'make EMBED_OPENSSL=false' then things should work out for you.

for the debian package problem: I'm not sure what's going on. I'm happy to try and spin up a VM with your OS and repro if you can let me know which OS it is.

Hey, thanks for the info. I'm using it on vagrant ubuntu/trusty64 so a 14.04 64bit Ubuntu with the stock compiler.
