⑴ 如何使用 sdk交叉編譯ros
使用ros_qtc_plugin插件新建項目
使用插件新建項目Import ROS
Workspace選項僅新建工作空間導入現工作空間新建文件ROS面Package、Basic
Node等選項創建package節點、launch文件、urdf文件等
現我創建新catkin工作空間,並且面創建package
1、新建項目
文件——新建文件或項目選擇Import ROS Workspace——choose圖
填寫catkin工作空間名字位置圖
我Namecatkin工作空間文件夾名字相同（同）名catkin_new選擇瀏覽——創建文件夾創建名catkin_new文件夾圖按車再選擇打
現框詢問新建工作空間未初始化否執行初始化我選擇yes
相於執行catkin_init_workspace命令使工作空間初始化
點擊Generate Project File再點擊步
項目管理步驟配置版本控制系統我選擇完圖
建工作空間catkin_new空圖
2、創建package
接我工作空間創建新package
catkin_new面src右鍵單擊選擇添加新文件圖
選擇ROS——package——choose
填寫package名字test1
填寫作者(Authors)維護者(Maintainers)Qt環境部沒配置文支持請要用文否則新建package或者新建package面package.xml空文件
DependenciesCatkin欄填寫依賴通用C++寫節點需要添加roscpp依賴
圖
點擊完
3、添加新節點
目前package空沒任何節點
我test1src文件夾右鍵單擊選擇添加新文件
選擇ROS——Basic Node——choose創建節點新建.cpp文件
節點名稱寫node1則名node1.cpp源文件
用ROS模板新建node1.cpp源文件圖自Hello World程序
4、編譯節點
讓編譯執行文件我需要編輯test1makefile圖
test1CMakeLists.txt加面幾行意思node1.cpp編譯名node1節點
add_executable(node1 src/node1.cpp)
target_link_libraries(node1
${catkin_LIBRARIES}
)
⑵ c++的程序在ros下怎麼運行
1 先建立工作空間~/catkin_ws
2 在工作空間~/catkin_ws下創建包pkg目錄second
好處是通過創建包自動生成package.xml和CMakeLists.txt
3 在second目錄下創建hello.cpp源代碼文件
～～～～～～～～～～～～～～～～～～～～～～～～～～～
eagle:~/catkin_ws$ cd src
eagle:~/catkin_ws/src$ tree second/
second/
├── CMakeLists.txt
├── package.xml
└── src
└── hello.cpp
1 directory, 3 files
4 編寫hello.cpp文件
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#include <ros/ros.h>
int main(int argc, char **argv) {
ros::init(argc, argv, "helloros1234444");
ros::NodeHandle n;
ROS_INFO("Hello, ROS!");
ros::spinOnce();
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
5 修改編譯makefile文件 CMakeLists.txt
～～～～～～～～～～～～～～～～～～
cmake_minimum_required(VERSION 2.8.3)
project(simple_examples)
find_package(catkin REQUIRED COMPONENTS roscpp)
catkin_package()
include_directories(include $catkin_INCLUDE_DIRS)
add_executable(hello hello.cpp)
target_link_libraries(hello ${catkin_LIBRARIES})
～～～～～～～～～～～～～～～～～～
6 回到~/catkin_ws編譯程序
liao@liao-eagle:~/catkin_ws$ catkin_make

7.1一個終端里運行roscore
7.2 另外一個終端里運行 rosrun second hello
