CommonAPI C++ with D-Bus

前提准备

  1. CommonAPI 3.2.0
  2. Ubuntu 16
  3. Installed git and (CMake >=2.8)
  4. Java 8 runtime

可能需要安装如下软件包:

sudo apt install cmake cmake-qt-gui libexpat-dev expat default-jre

构建CommonAPI Runtime库

git clone -b 3.2.0 https://github.com/GENIVI/capicxx-core-runtime.git

构建CommonAPI Runtime库不需要任何外部依赖:

cd  ~/workspace/capicxx-core-runtime/
mkdir build && cd build
cmake ..
make

最终成功后会获得 libCommonAPI.so, 也可以将生成的库安装到其它目录

若需要生成文档, 请先安装 doxygen sudo apt-get install doxygen

cd  ~/workspace/capicxx-core-runtime/build
doxygen

构建CommonAPI D-Bus Runtime库

git clone -b 3.2.0 https://github.com/GENIVI/capicxx-dbus-runtime.git

CommonAPI D-Bus Runtime库构建需要依赖特定的版本的libdbus

cd  ~/workspace/
wget http://dbus.freedesktop.org/releases/dbus/dbus-1.10.10.tar.gz
tar -xzf dbus-1.10.10.tar.gz
cd dbus-1.10.10/

用CommonAPI D-Bus Runtime源码目录下的补丁打patch

for i in ../capicxx-dbus-runtime/src/dbus-patches/*.patch; do patch -p1 < $i; done

构建 libdbus

cd ~/workspace/dbus-1.10.10/
./configure
make

开始构建 CommonAPI D-Bus Runtime

cd  ~/workspace/capicxx-dbus-runtime
mkdir build && cd build
export PKG_CONFIG_PATH="~/workspace/dbus-1.10.10"
cmake -DUSE_INSTALLED_COMMONAPI=OFF -DUSE_INSTALLED_DBUS=OFF ..
make

最终成功后会获得 libCommonAPI-DBus.so

定义Franca接口文件和生成代码

cd ~/workspace && mkdir -p COVESA_prjs/dbus/fidl
cd COVESA_prjs/dbus/fidl
vi HelloWorld.fidl
package commonapi

interface HelloWorld {
  version {major 1 minor 0}
  method sayHello {
    in {
      String name
    }
    out {
      String message
    }
  }
}

下载 commonapi_core_generator & commonapi_dbus_generator 后解压至 ~/workspace

cd ~/workspace/COVESA_prjs/dbus
.~/workspace/commonapi_core_generator/commonapi-core-generator-windows-x86_64 -sk ./fidl/HelloWorld.fidl

.~/workspace/commonapi_dbus_generator/commonapi-dbus-generator-linux-x86_64 ./fidl/HelloWorld.fidl

一切顺利后会在 fidl的同级目录下生成 src-gen目录及目录里的文件

编写client和service程序

HelloWorldClient.cpp

HelloWorldService.cpp

然后再编写service的实现

HelloWorldStubImpl.hpp

HelloWorldStubImpl.cpp

编译运行

cmake_minimum_required(VERSION 2.8)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread -std=c++0x")
set(RUNTIME_PATH "/home/xxx/workspace")
set(DBUS_PATH "${RUNTIME_PATH}/dbus-1.10.10")
include_directories(
    src-gen
    ${RUNTIME_PATH}/capicxx-core-runtime/include
    ${RUNTIME_PATH}/capicxx-dbus-runtime/include
    ${DBUS_PATH}
)
link_directories(
    ${RUNTIME_PATH}/capicxx-core-runtime/build
    ${RUNTIME_PATH}/capicxx-dbus-runtime/build
    ${DBUS_PATH}/dbus/.libs
)
add_executable(HelloWorldClient
	src/HelloWorldClient.cpp
	src-gen/v1/commonapi/HelloWorldDBusProxy.cpp
	src-gen/v1/commonapi/HelloWorldDBusDeployment
)
target_link_libraries(HelloWorldClient CommonAPI CommonAPI-DBus dbus-1)
add_executable(HelloWorldService
	src/HelloWorldService.cpp
	src/HelloWorldStubImpl.cpp
	src-gen/v1/commonapi/HelloWorldDBusStubAdapter.cpp
	src-gen/v1/commonapi/HelloWorldStubDefault
	src-gen/v1/commonapi/HelloWorldDBusDeployment
)
target_link_libraries(HelloWorldService CommonAPI CommonAPI-DBus dbus-1)

cd ~/workspace/COVESA_prjs/dbus && mkdir build && cd build
cmake ..
make
./HelloWorldService &
./HelloWorldClient
