Compiling Errors
dbersan opened this issue · 6 comments
On my first trial to use the library, for ROS Kinetic on Ubuntu 16.04.
Installed using apt - ok
sudo apt-get install ros-kinetic-rviz-visual-tools
Ran Rviz and the demo - ok
roslaunch rviz_visual_tools demo_rviz.launch
roslaunch rviz_visual_tools demo.launch
Then I tried the cpp code, and got error...
Included headers
#include <rviz_visual_tools/rviz_visual_tools.h>
Added code to main():
rviz_visual_tools::RvizVisualToolsPtr visual_tools_;
visual_tools_.reset(new rviz_visual_tools::RvizVisualTools("base_frame","/rviz_visual_markers"));
Got many compile errors:
Looks like you'r not compiling with c++11? Did you make the appropriate changes to your cmake and package files in order to use the library?
@mcevoyandy No I didn't change anything inside the CMakeLists.txt (is that what you meant?). The tutorial didn't specify anything... What should I change exactly?
When you say "I tried the cpp code" I assume you have your own package that you're trying to use this in?
If so, add rviz_visual_tools to find_package in your CMakeLists.txt file and add rviz_visual_tools as a depend in your package.xml file.
Ok, now my CMakeLists.txt has
find_package(catkin REQUIRED COMPONENTS
pcl_conversions
pcl_ros
roscpp
sensor_msgs
rviz_visual_tools
)
And package.xml has
<build_depend>rviz_visual_tools</build_depend>
<exec_depend>rviz_visual_tools</exec_depend>
Still got the same errors.
So I set it to use C++11 as described here and then it compiled.
Maybe adding these info to the readme? Would probably save people sometime. It's wonderful when you just follow the usage steps and things work. Thank you anyway!
Yes, I forgot to mention the C++11, but that one was explicit in your compile errors. If you think the readme could benefit from additional explanation we'd love to review a pull request.
@dhiegomaga please contribute to improving the README.md!
