Question

我正在尝试使用此处的说明设置ROS安装：

http://developer.dji.com/onboard-sdk/documentation/sample-doc/sample-setup.html#ros-oes

具体来说，我很高兴，事情安装成功，直到我到达第4步：

Building the ROS Nodes
4. If you don't have a catkin workspace, create one as follows:
mkdir catkin_ws
cd catkin_ws
mkdir src
cd src
catkin_init_workspace

这个catkin_ws去哪儿了？在上一步中，我们在~MyUser / Onboard-SDK / build /中，但这似乎不是安装catkin_ws的正确位置？截至目前，我已尝试在~MyUser / Onboard-SDK / build / catkin_ws的build文件夹中安装catkin_ws，这在步骤6之后出错：

6. Build the dji_sdk ROS package and the dji_sdk_demo ROS package.
cd ..
catkin_make

错误：

"/home/sixarms/Onboard-SDK/build/catkin_ws/src/Onboard-SDK-
ROS/dji_sdk/include/dji_sdk/dji_sdk_node.h:17:19: fatal error: tf/tf.h: 
No such file or directory”

然后我删除了MyUser /文件夹中的所有内容并重新启动，这次我在与OnBoard-SDK相同的文件夹中创建了一个catkin_ws（即同一个文件夹中的MyUser / OnBoard-SDK的〜MyUser / catkin_with）在第6步得到致命错误，完全一样。找不到tf / tf.h。嗯：/

Answer 1

catkin_ws或您提供给它的任何其他名称可以转到任何地方，不同的ros包或dji_sdks或任何其他sdks然后进入catkin_ws/src/。

在第4步之后（创建工作区并初始化它），您应该在catkin_ws内catkin_ws/src/克隆dj_sdk包，从$ . devel/setup.bash中获取setup.bash脚本catkin_ws/。然后从$ catkin_make内再次运行catkin_ws/。

Answer 2

我有这个问题，我的解决方案是安装完整版本的ROS而不是基本版本：

<html><head></head><body> <p>Please wait while we redirect you to Your APP NAME...</p> <p><a href="javascript:redirectToApp()">Open appname</a></p> <script> var redirectToApp = function() { var scheme = "appnameapp"; var openURL = "appname" + window.location.pathname + window.location.search + window.location.hash; var iOS = /iPad|iPhone|iPod/.test(navigator.userAgent); var Android = /Android/.test(navigator.userAgent); var newLocation; if (iOS) { newLocation = scheme + ":" + openURL; } else if (Android) { newLocation = "intent://" + openURL + "#Intent;scheme=" + scheme + ";package=com.appnameapp;end"; } else { newLocation = scheme + "://" + openURL; } console.log(newLocation) window.location.replace(newLocation); } window.onload = redirectToApp; </script> </body></html>

在哪里安装适用于DJI Onboard-SDK ROS的catkin_ws
