64位 Fedora 24

安装protobuf

$ git clone https://github.com/google/protobuf.git

$ cd protobuf/

$ ./autogen.sh

$ ./configure

$ make -j8

$ sudo make install

### 设置pkg-config查找路径

$ tail -n 8 .bash_profile

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

export PKG_CONFIG_PATH

LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

export LD_LIBRARY_PATH

$ source ~/.bash_profile

工程目录结构（模板）

$ ls

build  CMakeLists.txt  proto  reader.cpp  README.txt  writer.cpp

$ cat CMakeLists.txt

#cmake的最低版本

cmake_minimum_required(VERSION 2.8)

#工程名

project(protobuf)

include(CheckCXXCompilerFlag)

CHECK_CXX_COMPILER_FLAG("-std=c++0x" COMPILER_SUPPORTS_CXX0X)

if(COMPILER_SUPPORTS_CXX11)

    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

elseif(COMPILER_SUPPORTS_CXX0X)

    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x")

else()

        message(STATUS "The compiler ${CMAKE_CXX_COMPILER} has no C++11 support. Please use a different C++ compiler.")

#遍历当前目录及子目录获取所有源文件

file(GLOB SRC "${CMAKE_CURRENT_SOURCE_DIR}/*.cc")

file(GLOB WSRC "${CMAKE_CURRENT_SOURCE_DIR}/writer.cpp")

file(GLOB RSRC "${CMAKE_CURRENT_SOURCE_DIR}/reader.cpp")

#设置源文件列表

add_executable(reader ${RSRC} ${SRC})

INCLUDE(FindPkgConfig)

#使用pkg-config寻找protobuf库的include目录以及库

pkg_check_modules(PROTOBUF REQUIRED protobuf)

include_directories(${PROTOBUF_INCLUDE_DIRS})

link_directories(${PROTOBUF_LIBRARY_DIRS})

#设置链接库

target_link_libraries(writer ${PROTOBUF_LIBRARIES})

target_link_libraries(reader ${PROTOBUF_LIBRARIES})

#新增自定义命令pb和cls

add_custom_target(pb

    COMMAND protoc -I=${CMAKE_CURRENT_SOURCE_DIR}/proto --cpp_out=${CMAKE_CURRENT_SOURCE_DIR} ${CMAKE_CURRENT_SOURCE_DIR}/proto/*.proto

)

add_custom_target(cls

    COMMAND rm -rf ${CMAKE_CURRENT_SOURCE_DIR}/*.pb.*

)

编译运行项目（模板）

$ mkdir build

$ cd build

$ cmake ..

$ make clean

$ make cls

$ make pb

$ make

$ ./writer

$ ./reader
