| ## C++ 原生接口 |
| |
| ### 依赖 |
| |
| - Java 8+ |
| - Maven 3.5+ |
| - Flex |
| - Bison 2.7+ |
| - Boost 1.56+ |
| - OpenSSL 1.0+ |
| - GCC 5.5.0+ |
| |
| |
| ### 安装方法 |
| |
| 编译 C++客户端之前首先需要本地编译 Thrift 库,compile-tools 模块负责编译 Thrift,之后再编译 client-cpp。 |
| |
| #### 在 Mac 上编译 Thrift |
| |
| - Bison |
| |
| Mac 环境下预安装了 Bison 2.3 版本,但该版本过低不能够用来编译 Thrift。使用 Bison 2.3 版本是会报以下错误: |
| |
| ```invalid directive: '%code'``` |
| |
| 使用下面 brew 命令更新 bison 版本 |
| |
| ``` shell |
| brew install bison |
| brew link bison --force |
| ``` |
| |
| 添加环境变量: |
| |
| ``` shell |
| echo 'export PATH="/usr/local/opt/bison/bin:$PATH"' >> ~/.bash_profile |
| ``` |
| |
| - Boost |
| |
| 确保安装较新的 Boost 版本: |
| |
| ```shell |
| brew install boost |
| brew link boost |
| ``` |
| |
| - OpenSSL |
| |
| 确保 openssl 库已安装,默认的 openssl 头文件路径为"/usr/local/opt/openssl/include" |
| 如果在编译 Thrift 过程中出现找不到 openssl 的错误,尝试添加 |
| |
| `-Dopenssl.include.dir=""` |
| |
| #### 在 Linux 上编译 Thrift |
| |
| Linux 下需要确保 g++已被安装。 |
| |
| Ubuntu 20: |
| |
| 一条命令安装所有依赖库: |
| |
| ```shell |
| sudo apt-get install gcc-9 g++-9 libstdc++-9-dev bison flex libboost-all-dev libssl-dev zlib1g-dev |
| ``` |
| |
| CentOS 7.x: |
| |
| 在centos 7.x里,可用yum命令安装部分依赖。 |
| |
| ```shell |
| sudo yum install bison flex openssl-devel |
| ``` |
| |
| 使用yum安装的GCC、boost版本过低,在编译时会报错,需自行安装或升级。 |
| |
| #### 在 Windows 上编译 Thrift |
| |
| - 编译构建环境 |
| |
| 保证你的 Windows 系统已经搭建好了完整的 C/C++的编译构建环境。可以是 MSVC,MinGW 等。 |
| |
| 如使用 MS Visual Studio,在安装时需要勾选 Visual Studio C/C++ IDE and compiler(supporting CMake, Clang, MinGW)。 |
| |
| - CMake |
| |
| CMake 官网下载地址 https://cmake.org/download/ |
| |
| CMake 需要根据不同编译平台使用不同的生成器。CMake 支持的生成器列表如下 (`cmake --help`的结果): |
| |
| ``` |
| Visual Studio 16 2019 = Generates Visual Studio 2019 project files. |
| Use -A option to specify architecture. |
| Visual Studio 15 2017 [arch] = Generates Visual Studio 2017 project files. |
| Optional [arch] can be "Win64" or "ARM". |
| Visual Studio 14 2015 [arch] = Generates Visual Studio 2015 project files. |
| Optional [arch] can be "Win64" or "ARM". |
| Visual Studio 12 2013 [arch] = Generates Visual Studio 2013 project files. |
| Optional [arch] can be "Win64" or "ARM". |
| Visual Studio 11 2012 [arch] = Generates Visual Studio 2012 project files. |
| Optional [arch] can be "Win64" or "ARM". |
| Visual Studio 10 2010 [arch] = Generates Visual Studio 2010 project files. |
| Optional [arch] can be "Win64" or "IA64". |
| Visual Studio 9 2008 [arch] = Generates Visual Studio 2008 project files. |
| Optional [arch] can be "Win64" or "IA64". |
| Borland Makefiles = Generates Borland makefiles. |
| * NMake Makefiles = Generates NMake makefiles. |
| NMake Makefiles JOM = Generates JOM makefiles. |
| MSYS Makefiles = Generates MSYS makefiles. |
| MinGW Makefiles = Generates a make file for use with |
| mingw32-make. |
| Unix Makefiles = Generates standard UNIX makefiles. |
| Green Hills MULTI = Generates Green Hills MULTI files |
| (experimental, work-in-progress). |
| Ninja = Generates build.ninja files. |
| Ninja Multi-Config = Generates build-<Config>.ninja files. |
| Watcom WMake = Generates Watcom WMake makefiles. |
| CodeBlocks - MinGW Makefiles = Generates CodeBlocks project files. |
| CodeBlocks - NMake Makefiles = Generates CodeBlocks project files. |
| ``` |
| |
| 编译 client-cpp 时的 mvn 命令中添加 -Dcmake.generator="" 选项来指定使用的生成器名称。 |
| |
| `mvn package -Dcmake.generator="Visual Studio 15 2017 [arch]"` |
| |
| - Flex 和 Bison |
| |
| Windows 版的 Flex 和 Bison 可以从 SourceForge 下载:https://sourceforge.net/projects/winflexbison/ |
| |
| 下载后需要将可执行文件重命名为 flex.exe 和 bison.exe 以保证编译时能够被找到,添加可执行文件的目录到 PATH 环境变量中。 |
| |
| - Boost |
| |
| Boost 官网下载地址 https://www.boost.org/users/download/ |
| |
| 依次执行 bootstrap.bat 和 b2.exe,本地编译 boost |
| |
| ```shell |
| bootstrap.bat |
| b2.exe |
| ``` |
| |
| 为了帮助 CMake 本地安装好的 Boost,在编译 client-cpp 的 mvn 命令中需添加: |
| |
| `-Dboost.include.dir=${your boost header folder} -Dboost.library.dir=${your boost lib (stage) folder}` |
| |
| - openssl |
| |
| openssl 官网源码下载地址 https://www.openssl.org/source/ |
| |
| 二进制文件下载地址 http://slproweb.com/products/Win32OpenSSL.html |
| |
| - 增加环境变量 |
| |
| 在编译前,需要确定cmake,flex,bison,openssl都加入了PATH。 |
| |
| #### 编译及测试 |
| |
| Maven 命令中添加"-P client-cpp" 选项编译 client-cpp 模块。client-cpp 需要依赖编译好的 thrift,即 compile-tools 模块。 |
| |
| - Mac , Linux 下,编译C++客户端完整命令如下: |
| |
| `mvn package -P compile-cpp -pl example/client-cpp-example -am -DskipTest` |
| |
| - Windows下,编译C++客户端: |
| |
| 编译前需额外添加Boost相关的参数: |
| |
| `-Dboost.include.dir=${your boost header folder} -Dboost.library.dir=${your boost lib (stage) folder}` |
| |
| 需指定cmake的generator,例如: |
| |
| `-Dcmake.generator="Visual Studio 15 2017 [arch]"` |
| |
| 完整编译C++客户端命令如下: |
| |
| ```shell |
| mvn package -P compile-cpp -pl client-cpp,server,example/client-cpp-example -am -Dcmake.generator="your cmake generator" -Dboost.include.dir=${your boost header folder} -Dboost.library.dir=${your boost lib (stage) folder} -DskipTests |
| ``` |
| |
| 编译成功后,打包好的 zip 文件将位于:"client-cpp/target/client-cpp-${project.version}-cpp-${os}.zip" |
| |
| 解压后的目录结构如下图所示 (Mac): |
| |
| ```shell |
| . |
| +-- client |
| | +-- include |
| | +-- Session.h |
| | +-- TSIService.h |
| | +-- rpc_types.h |
| | +-- rpc_constants.h |
| | +-- thrift |
| | +-- thrift_headers... |
| | +-- lib |
| | +-- libiotdb_session.dylib |
| ``` |
| |
| ### Q&A |
| |
| #### Mac 相关问题 |
| |
| 本地 Maven 编译 Thrift 时如出现以下链接的问题,可以尝试将 xcode-commandline 版本从 12 降低到 11.5 |
| |
| https://stackoverflow.com/questions/63592445/ld-unsupported-tapi-file-type-tapi-tbd-in-yaml-file/65518087#65518087 |
| |
| #### Windows 相关问题 |
| |
| Maven 编译 Thrift 时需要使用 wget 下载远端文件,可能出现以下报错: |
| |
| ``` |
| Failed to delete cached file C:\Users\Administrator\.m2\repository\.cache\download-maven-plugin\index.ser |
| ``` |
| |
| 解决方法: |
| |
| - 尝试删除 ".m2\repository\\.cache\" 目录并重试。 |
| - 在添加 pom 文件对应的 download-maven-plugin 中添加 "\<skipCache>true\</skipCache>" |
