proto_cmake_test
Proto与CMAKE结合编译源代码
工程编译
cd build
cmake ..
make
ls message/*
在message目录下生成cc和h文件
三种CMakelists编写方式
-
第一种
cmake_minimum_required(VERSION 2.6)
project(proto_cmake_test)
add_definitions(-std=c++11)
find_package(Protobuf REQUIRED)
find_package(Threads)
if(PROTOBUF_FOUND)
message(STATUS "protobuf library found")
else()
message(FATAL_ERROR "protobuf library is needed but cant be found")
endif()
#endif()
# 设置编译阶段头文件路径
include_directories( ${CMAKE_CURRENT_BINARY_DIR}
${PROTOBUF_INCLUDE_DIRS}
"/usr/include/")
# 设置链接截断库文件路径
link_directories( /usr/lib/x86_64-linux-gnu/
#${EIGEN3_LIBRARY_DIRS}
)
# 找到所有需要编译的.proto文件
file(GLOB PROTO_FILES ${PROJECT_SOURCE_DIR}/proto/*.proto)
message(STATUS "1-- ${PROTO_FILES}")
# 法一：要求protobuf_generate_cpp命令和生成add_executable() 或 add_library() 的命令必须在同一个CMakeList中.
## PROTO_SRC,PROTO_HARS变量分别指代生成的cpp和h文件并可用于连接到target和设置include
set(PROTOBUF_GENERATE_CPP_APPEND_PATH ON) # required for tensorflow
protobuf_generate_cpp(PROTO_SRCS PROTO_HDRS ${PROTO_FILES})
## 生成动态库
add_library(proto_lib STATIC ${PROTO_SRCS} ${PROTO_HDRS})
## 与C++文件一起编译生成可执行文件
#add_executable(bar bar.cc ${PROTO_SRCS} ${PROTO_HDRS})
