Question

我有protobuf编译器版本3.0，需要安装grpc和grpc python插件。在本教程之后，我将deb http://http.debian.net/debian jessie-backports main添加到我的sources.list文件中，并返回了sudo apt-get update和sudo apt-get install libgrpc-dev

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

所以，我决定从INSTALL笔记中提到的源代码编译它并做了：

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

然而，在制作步骤中，我得到了

[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

切换到release-0_11分支时，运行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

我无法弄清楚如何安装它。任何帮助将不胜感激。

对我来说，在我将文件更改为：

更具体地说，请打开文件src/compiler/csharp_generator.cc并将 GetUflectionClassName 的所有引用替换为 GetReflectionClassName

向后工作：

for release-0_11：看起来你正试图针对最新的protobuf进行编译。由于我们现在都处于开发状态，偶尔会出现故障 - 但grpc确实跟踪了它在third_party / protobuf中测试过的protobuf的版本。尝试签出并安装该版本。我提交了https://github.com/grpc/grpc/issues/4697来更新最新的protobuf 3.0版本。

对于github的master：你使用的是哪个编译器和操作系统？我最近检查了boringssl集成工作，所以它很新鲜，而且几乎没有经过考验。我想让它经受战斗考验。也就是说，如果你做了一个“make EMBED_OPENSSL = false＆＃39;那么事情应该适合你。

对于debian包问题：我不确定是怎么回事。如果您能告诉我它是哪个操作系统，我很高兴尝试使用您的操作系统和重新启动虚拟机。
