cmake error catkin package
I am following the tutorials in order and have been asked to configure the catkin environment at stage 5 of this web page: link text
The error I am receiving is as follows (bold below):
cmake_minimum_required(VERSION 2.8.3)
project(beginner_tutorials)
find_package(catkin REQUIRED COMPONENTS
roscpp
rospy
std_msgs
message_generation
)
## Generate messages in the 'msg' folder

Everything above is copied exactly from the CMakeLists.txt file
this is the actual error, the rest is normal output.
Please edit your question and include the contents of your
CMakeLists.txt. Please remove all comments from it, we don't need those.The sourcing is fine. You need to source both, ROS's setup script in
/opt/ros/kineticdirectory and your catkin ws as well.No, that is actually not necessary. By default,
source-ing onesetup.bashafter another will actually make the secondsetup.bashoverwrite whatever the firstsetup.bashconfigured. So sourcing your workspace after/opt/ros/$distrodoes not work the way you imply.Don't you have to source all your own created packages for ROS to be able to find them?
no, you have to
sourceyour own workspaces. As you cannot compile your workspace withoutsource-ing/opt/ros/$distro, and doing that will result in/opt/ros/$distrobeing extended by your workspace,source-ing your workspace will automatically alsosource /opt/ros/$distro(in a way).Oh, I didn't know that. Thanks for clarification.
Thanks for the directory sourcing comments. I know everything is okay there now!
I have added the CMakeLists.txt file and have deleted the other comments. However the action files comment is still in there. I'm not sure if this is the reason why there were unused arguments in the original problem.
Seeing as the error is actually in this bit, please copy-paste those lines from your
CMakeLists.txtinto your question verbatim. Don't leave anything out.
