there isn't the file falconSetPoint.h about ros_falcon HOT 22 CLOSED

This seems to be an issue with the latest ROS releases where the msg packages (deps) aren't built before the target for ros_falcon is being compiled. As per your question, the falconSetPoint does exist in the msg folder so that isn't the issue I think. There are two solutions.

1. Explicitly build the message before using the command catkin_make. I don't have linux on hand so can't verify but it should be "catkin_make --pkg ros_falcon_msgs". Just double check the "ros_falcon_msgs" name using "rosmsg show <msg_package_name>" to verify that the message files are there now.

2. I have found that using catkin_make multiple times also solves the problem. "catkin_make" would fail a few times but does end up succeeding eventually.

Lastly, it should work using the catkin build after the first step but I don't have linux to test that for a few days.

Thanks for your reply. I try build it several times and it works.

I have the same problem, but the previous solution did not work for me. @adnanmunawar

from ros_falcon.

Can you please specify your OS and preferably your ROS version

from ros_falcon.

@adnanmunawar is Ubuntu and ROS kinetic

from ros_falcon.

Are you sure you have installed libnifalcon as mentioned in the README?

from ros_falcon.

@adnanmunawar , yes, I did it

from ros_falcon.

Please paste the output of your build commands cmake and make

from ros_falcon.

@adnanmunawar This is the message when using catkin_make:

I briefly glanced the output, it seems you changed the name of your package from ros_falcon to falcon. Then you also seemed to have modified your src files includes from ros_falcon to rosfalcon. You need to be consistent with your naming.

from ros_falcon.

I renamed the package and get this:

CMake Warning (dev) in CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of
code such as

project(ProjectName)

near the top of the file, but after cmake_minimum_required().

CMake is pretending there is a "project(Project)" command on the first
line.
This warning is for project developers. Use -Wno-dev to suppress it.

from ros_falcon.

You need to clear your build and devel folder, remove the package from your src tree and then clone a fresh copy without any of your edits and then try to compile

from ros_falcon.

@adnanmunawar thanks a lot. It works, but I realized that I did not install libnifalcon correctly. I got this message:

omar@omar-All-Series:~/catkin_ws$ rosrun rosfalcon falcon_node
/home/omar/catkin_ws/devel/lib/rosfalcon/falcon_node: error while loading shared libraries: libnifalcon.so.1.0.2: cannot open shared object file: No such file or directory

from ros_falcon.

I do not how to install it, I got confuse cause I just cloned the libnifalcon package in my workspace src folder

from ros_falcon.

So I would suggest to NOT clone the libnifalcon to catkin workspace (ROS src folder). But instead just clone it in your home directory. Then, after the cmake and make command in the build folder, make sure to run the make install command. You might need sudo for the make install command.

from ros_falcon.

I did all that you told me but I got this message:

rosrun rosfalcon falcon_node
/home/omar/catkin_ws/devel/lib/rosfalcon/falcon_node: error while loading shared libraries: libnifalcon.so.1.0.2: cannot open shared object file: No such file or directory

from ros_falcon.

Why are you renaming the files and executables? If you create/comment on an existing issue, make sure to state what you have modified. There isn't any executable named falcon_node in the package. Nor is the name of the package rosfalcon.

from ros_falcon.

I do not renamed them, and falcon_node exists, I saw it in the path that the shell indicates

from ros_falcon.

Closing this issue as the solution specified in #2 (comment)

from ros_falcon.
