How to generate C++ files for grpc from .proto files on Windows ( cross platform way using CMake)?
To generate C++ files for gRPC from .proto files on Windows in a cross-platform way using CMake, you can follow these steps:
Install Protocol Buffers (protobuf) Compiler:
- Download the latest Protocol Buffers compiler (protoc) for Windows from the official GitHub repository: https://github.com/protocolbuffers/protobuf/releases
- Extract the downloaded archive and add the location of the protoc compiler executable to your system's PATH environment variable.
Set Up CMake:
- Install CMake if you haven't already. You can download the latest version from the official CMake website: https://cmake.org/download/
- Add the CMake executable to your system's PATH environment variable.
Set Up gRPC and Protocol Buffers C++ Libraries:
- Use a package manager or download the gRPC and Protocol Buffers C++ libraries for Windows and ensure they are available in your project.
- Alternatively, you can use CMake's FetchContent or ExternalProject modules to automatically download and build the libraries as part of your CMake build process.
Configure CMakeLists.txt:
In your project's CMakeLists.txt file, add the following lines to set up the gRPC and Protocol Buffers C++ libraries and generate the C++ files from .proto files:
cmakefind_package(Protobuf REQUIRED)
find_package(gRPC CONFIG REQUIRED)
set(PROTO_FILES <list_of_proto_files>)
set(GENERATED_FILES_DIR ${CMAKE_CURRENT_BINARY_DIR}/generated)
# Generate C++ files from .proto files
protobuf_generate_cpp(PROTO_SRCS PROTO_HDRS ${GENERATED_FILES_DIR} ${PROTO_FILES})
grpc_generate_cpp(GRPC_SRCS GRPC_HDRS ${GENERATED_FILES_DIR} ${PROTO_FILES})
include_directories(${GENERATED_FILES_DIR})
Replace
<list_of_proto_files>
with the list of .proto files in your project.
Add Generated Files to Your Target:
Add the generated .cpp files to your target using
add_executable
oradd_library
in your CMakeLists.txt file:cmakeadd_executable(MyApp main.cpp ${PROTO_SRCS} ${GRPC_SRCS})
target_link_libraries(MyApp gRPC::grpc++)
Adjust the target name and source files according to your project.
Build and Run:
Use CMake to build your project and generate the necessary C++ files:
bashcmake -B build
cmake --build build --config Release
Replace
build
with the desired build directory name.
By following these steps, you should be able to generate the necessary C++ files for gRPC from your .proto files using CMake on Windows in a cross-platform manner.
