在Ubuntu上安装/编译grpc时出错

Question

我有protobuf编译器版本3.0，需要安装grpc和grpc python插件。在教程之后，我将deb http://http.debian.net/debian jessie-backports main添加到我的来源.列表file和did sudo apt-get update和sudo apt-get install libgrpc-dev返回

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

因此，我决定从安装说明中提到的源代码编译它，并执行了以下操作：

^{pr2}$

但是，在make步骤中，我得到

[MAKE]    Generating cache.mk
make: Circular /home/vagrant/grpc2/grpc/libs/opt/libboringssl.a <- /home/vagrant/grpc2/grpc/libs/opt/libboringssl.a dependency dropped.

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

在切换到release-0_11分支时，运行make结果

[HOSTCXX] Compiling src/compiler/csharp_generator.cc

make: *** [/home/vagrant/grpc2/grpc/objs/opt/src/compiler/csharp_generator.o] Error 1

我不知道怎么安装这个。任何帮助都将不胜感激。在

Answer 1

向后工作：

对于release-0_11：看起来您正在根据最新的protobuf进行编译。由于我们现在都在开发中，偶尔会有损坏-但是grpc确实跟踪protobuf的版本，它在第三方/protobuf中进行了测试。尝试签出并安装该版本。我归档了https://github.com/grpc/grpc/issues/4697以更新到最新的protobuf3.0版本。在

对于来自github的master：您使用哪个编译器和操作系统？我最近检查了boringssl的集成工作，所以它很新鲜，而且还没有经过战斗测试。我想做个战斗测试。也就是说，如果你做了一个“makeembed_OPENSSL=false”，那么事情应该会为你解决。在

对于debian包的问题：我不确定发生了什么。如果你能告诉我是哪个操作系统的话，我很乐意尝试用你的操作系统来启动一个虚拟机。在

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getumbrallClassName的所有引用替换为GetReflectionClassName
