Some (only some) email notification from answers.ros.org go to spam folder in GMail.com

Not sure if this is a similar issue with https://github.com/ros-infrastructure/roswiki/issues/297 or not, but I do see 39 emails from answers.ros.org ended up going into spam since 3/18/2020 (10 days ago).

Example is https://answers.ros.org/question/347349. The entire original email is below (accounts swapped).

I do see spf related error. 131.113.134.67 seems related to the domain of the recipient email I use, keio.ac.jp. If the error is rooted in to the setting at the recipient domain I don't mind contacting them, but honestly I'm not yet familliar with this error.

's answer:

Hello,You should have added those three lines after find_package(). The order does matter in CMakeLists.txt. Please see  http://wiki.ros.org/catkin/CMakeLists.txt#Overall_Structure_and_Ordering (wiki/catkin - CMakeLists.txt - Overall Structure and Ordering).I think your package does not contain any messages/services/actions files so you don't really needadd_dependencies(name_of_node_chatter my_package_generate_messages_cpp)

If you do, you need to add generate_messages(DEPENDENCIES ...). The message generation targets are created by generate_messages(DEPENDENCIES ...). Using add_dependencies(name_of_node_chatter my_package_generate_messages_cpp) is to ensure that my_package_generate_messages_cpp is built before the name_of_node_chatter target.If your target depends on other messages/services/actions from other packages, even though your package doesn't build any messages/services/actions at compile time, you should add add_dependencies(name_of_node_chatter ${catkin_EXPORTED_TARGETS})

More details about add_dependencies(...) can be found http://wiki.ros.org/catkin/CMakeLists.txt#Important_Prerequisites.2BAC8-Constraints (here).I think it's always safe to add a dependency on catkin_EXPORTED_TARGETS.

Hello,Firstly i need to say im totally beginner on ROS.I managed to install it and my Professor wanted to me complete these tasks;-Create a ROS package with your name.-Create two nodes, a chatter which publishes std_msgs and a listener

to listen to chatter.-The message you are required to send will be assigned for each one

separately.-The listener should get the message and print it using ROS_INFO

function.So i managed to create work space , but i stucked at somewhere that wants me to add these lines into my_package/CMakeLists.txt.lines are ;add_executable(name_of_node_chatter src/01.cpp) ,

target_link_libraries(name_of_node_chatter ${catkin_LIBRARIES}) ,

add_dependencies(name_of_node_chatter my_package_generate_messages_cpp)

https://imgur.com/a/nzSajPt (link text)But when i add them into CMakeList.txt like this ;

https://imgur.com/a/UnrGv0P (link text)After i save this txt file i try to run catkin_make command on terminal.It gaves me this error ;

https://imgur.com/a/Kr1Yo6s (link text)I don't know what to do , please can you help me to fix this problem.
