到目前为止，我已经尝试了 3 天来寻找如何在 Windows 上安装和使用 gRPC，但没有成功。我正在使用 Visual Studio 2015，Win7 64 位。为了安全起见，我会一步一步地写我正在做的事情。这可能没有必要，但我是 C++ 和 VS 的初学者，所以我完全不确定我是否正确:
(以下指南http://www.infopulse.com/blog/grpc-framework-by-google-tutorial/):
目前一切进展顺利。
从示例文件夹中的 proto 生成 c 文件。我得到 helloworld.grpc.pb.cc、helloworld.grpc.pb.h、helloworld.pb.cc 和 helloworld。 pb.h 并将它们全部移动到 grpc/examples/cpp/helloworld:
protoc --grpc_out=./hello_proto --plugin=protoc-gen-grpc=grpc_cpp_plugin.exe ../../examples/protos/helloworld.proto --proto_path=../../examples/protos
protoc --cpp_out=./hello_proto ../../examples/protos/helloworld.proto --proto_path=../../examples/protos
我保持 grpc.sln 在 VS 中打开并“添加”>“新项目”
当我尝试构建我的项目时，报告了找不到 gflags、gtest 和 libprotobuf 的错误。如果我找到所有内容并将它们移动到包含的文件夹中，则会收到以下错误:

如果有人能提供解决方案，我将不胜感激。
最佳答案
在我自己为此苦苦挣扎了一段时间后，我发现 vcpkg在为 Windows 构建 gRPC C++ 方面做得非常好。请注意，要求是 Window 7 或更高版本以及 VS2015 Update 3 或更高版本。请注意，您可以使用三元组以您想要的方式配置它，例如.\vcpkg.exe 安装 grpc --triplet x86-windows-static
关于c++ - Windows 上的 gRPC C++，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39982065/
我需要在客户计算机上运行Ruby应用程序。通常需要几天才能完成(复制大备份文件)。问题是如果启用sleep，它会中断应用程序。否则，计算机将持续运行数周，直到我下次访问为止。有什么方法可以防止执行期间休眠并让Windows在执行后休眠吗？欢迎任何疯狂的想法;-) 最佳答案 Here建议使用SetThreadExecutionStateWinAPI函数，使应用程序能够通知系统它正在使用中，从而防止系统在应用程序运行时进入休眠状态或关闭显示。像这样的东西:require'Win32API'ES_AWAYMODE_REQUIRED=0x0
我的瘦服务器配置了nginx，我的ROR应用程序正在它们上运行。在我发布代码更新时运行thinrestart会给我的应用程序带来一些停机时间。我试图弄清楚如何优雅地重启正在运行的Thin实例，但找不到好的解决方案。有没有人能做到这一点？ 最佳答案 #Restartjustthethinserverdescribedbythatconfigsudothin-C/etc/thin/mysite.ymlrestartNginx将继续运行并代理请求。如果您将Nginx设置为使用多个上游服务器，例如server{listen80;server

我将我的Rails应用程序部署到OpenShift，它运行良好，但我无法在生产服务器上运行“Rails控制台”。它给了我这个错误。我该如何解决这个问题？我尝试更新rubygems，但它也给出了权限被拒绝的错误，我也无法做到。railsc错误:Warning:You'reusingRubygems1.8.24withSpring.UpgradetoatleastRubygems2.1.0andrun`gempristine--all`forbetterstartupperformance./opt/rh/ruby193/root/usr/share/rubygems/rubygems
我正在尝试从Postgresql表(table1)中获取数据，该表由另一个相关表(property)的字段(table2)过滤。在纯SQL中，我会这样编写查询:SELECT*FROMtable1JOINtable2USING(table2_id)WHEREtable2.propertyLIKE'query%'这工作正常:scope:my_scope,->(query){includes(:table2).where("table2.property":query)}但我真正需要的是使用LIKE运算符进行过滤，而不是严格相等。然而，这是行不通的:scope:my_scope,->(que
这似乎非常适得其反，因为太多的gem会在window上破裂。我一直在处理很多mysql和ruby-mysqlgem问题(gem本身发生段错误，一个名为UnixSocket的类显然在Windows机器上不能正常工作，等等)。我只是在浪费时间吗？我应该转向不同的脚本语言吗？ 最佳答案 我在Windows上使用Ruby的经验很少，但是当我开始使用Ruby时，我是在Windows上，我的总体印象是它不是Windows原生系统。因此，在主要使用Windows多年之后，开始使用Ruby促使我切换回原来的系统Unix，这次是Linux。Rub
如何将send与+=一起使用？a=20;a.send"+=",10undefinedmethod`+='for20:Fixnuma=20;a+=10=>30 最佳答案 恐怕你不能。+=不是方法，而是语法糖。参见http://www.ruby-doc.org/docs/ProgrammingRuby/html/tut_expressions.html它说Incommonwithmanyotherlanguages,Rubyhasasyntacticshortcut:a=a+2maybewrittenasa+=2.你能做的最好的事情是:
之前在培训新生的时候，windows环境下配置opencv环境一直教的都是网上主流的vsstudio配置属性表，但是这个似乎对新生来说难度略高(虽然个人觉得完全是他们自己的问题)，加之暑假之后对cmake实在是爱不释手，且这样配置确实十分简单(其实都不需要配置)，故斗胆妄言vscode下配置CV之法。其实极为简单，图比较多所以很长。如果你看此文还配不好，你应该思考一下是不是自己的问题。闲话少说，直接开始。0.CMkae简介有的人到大二了都不知道cmake是什么，我不说是谁。CMake是一个开源免费并且跨平台的构建工具，可以用简单的语句来描述所有平台的编译过程。它能够根据当前所在平台输出对应的m

我对如何计算通过{%assignvar=0%}赋值的变量加一完全感到困惑。这应该是最简单的任务。到目前为止，这是我尝试过的:{%assignamount=0%}{%forvariantinproduct.variants%}{%assignamount=amount+1%}{%endfor%}Amount:{{amount}}结果总是0。也许我忽略了一些明显的东西。也许有更好的方法。我想要存档的只是获取运行的迭代次数。 最佳答案 因为{{incrementamount}}将输出您的变量值并且不会影响{%assign%}定义的变量，我
