Documentation on building/installing gRPC should somehow highlight the important of setting this variable for the first CMake invocation.Perhaps this should be controlled by a variable that defaults to CMAKE_CXX_STANDARD and if it's not set - to 11. There should be a way to set C++ standard used in gRPC CMake build.Point 2 also means that if a user wants to install gRPC using gRPC_INSTALL option, they must specify C++ standard used. Variables with PROTOBUF prefix are still supported for compatibility. Changed in version 3.6: All input and output variables use the Protobuf prefix. New in version 3.6: Support for findpackage () version checks. This means that if both gRPC and user's code want to depend on Abseil, they MUST use the same C++ standard. Locate and configure the Google Protocol Buffers library. Abseil is ABI-incompatible between different C++ standard versions, because it conditionally aliases some of its classes to standard library instead of defining them. With any dependency on Abseil library this becomes more dramatic. cmake: Doing 'install' on Windows does not install important files Issue 12384 grpc/grpc GitHub grpc / grpc Public Notifications Fork 10k 37.Build GRPC in C++ code with CMake and Docker. In this case the ordering of the flags makes both Clang and G++ use that C++17 (which is probably good), but this is relying on undocumented behavior. Easily write and run GRPC code in C++ without worrying about the GRPC setup for C++. If the user has CMAKE_CXX_STANDARD variable set (let's say, to 17) and includes gRPC with add_subdirectory, the command line for the calls will include both -std=c++11 and -std=c++17.There are several problems with this approach: CMake binpathcmake -versioncmake GRPC git GRPC gRPC >git clone -b v1.29. Reflection can be enabled by linking agains gRPC::grpc++reflection, enabling support for the grpc. For some background info, have a look at this blog post explaining how to structure gRPC projects with CMake. We have now downloaded our library so lets. (Not going to use the standard bug request form, because I am going to highlight a potential problem that would only become real with more use of Abseil).Ĭurrently C++ standard is set for gRPC by appending -std=c++11 to CMAKE_CXX_FLAGS. This is a basic example of a CMake project using Protobuf together with gRPC in C++. You should see the following output: Installing spdlog static libraries.
