JSONCPP开发环境搭建

Posted 2020-11-08 银魔术师

环境设置

项目地址

https://github.com/open-source-parsers/jsoncpp.git

操作系统

64位 Fedora 24

安装jsoncpp

$ git clone https://github.com/open-source-parsers/jsoncpp.git
$ cd jsoncpp/
$ mkdir -p build/debug
$ cd build/debug
$ cmake -DCMAKE_BUILD_TYPE=debug -DBUILD_STATIC_LIBS=ON -DBUILD_SHARED_LIBS=OFF ../..
$ make
$ sudo make install
### 设置pkg-config查找路径
$ tail -n 8 .bash_profile

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/lib64/pkgconfig

export PKG_CONFIG_PATH

LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib64:$LD_LIBRARY_PATH

export LD_LIBRARY_PATH
$ source ~/.bash_profile
### 生成帮助文档，web文档的index.html在当前目录%DOC_TOPDIR%/%HTML_OUTPUT%下
$ sudo yum install -y doxygen
$ doxygen web_doxyfile.in

工程目录结构（模板）

$ ls
CMakeLists.txt  main.cpp
$ cat CMakeLists.txt
#cmake的最低版本
cmake_minimum_required(VERSION 2.8)

#工程名
project(jsoncpp)

include(CheckCXXCompilerFlag)
CHECK_CXX_COMPILER_FLAG("-std=c++11" COMPILER_SUPPORTS_CXX11)
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.")
endif()

#遍历当前目录及子目录获取所有源文件
file(GLOB SRC "${CMAKE_CURRENT_SOURCE_DIR}/*.cpp")

#设置源文件列表
add_executable(sample ${SRC})

#dependencies
INCLUDE(FindPkgConfig)
#使用pkg-config寻找protobuf库的include目录以及库
pkg_check_modules(JSONCPP REQUIRED jsoncpp)
include_directories(${JSONCPP_INCLUDE_DIRS})
link_directories(${JSONCPP_LIBRARY_DIRS})
#设置链接库
target_link_libraries(sample ${JSONCPP_LIBRARIES})

编译运行项目（模板）

$ mkdir build
$ cd build
$ cmake ..
$ make
$ ./sample
