Hi,

I intend to convert quaternion into rpy using btMatrix3x3.getRPY(). However, i get the following error when i try to compile.

this is done with only #include <LinearMath/btMatrix3x3.h> included in my cpp file. /home/chao/catkin_ws/src/simple_navigation_goals/src/robot_state3_with_class.cpp:23:36: fatal error: LinearMath/btMatrix3x3.h: No such file or directory compilation terminated.

this error msg showed up when i added <depend package="LinearMath"/> into the manifest.xml

[rospack] Error: package/stack 'simple_navigation_goals' depends on non-existent package 'LinearMath' and rosdep claims that it is not a system dependency. Check the ROS_PACKAGE_PATH or try calling 'rosdep update'

appreciate your help, thank you

You don't mention which ROS distribution you are using, but if it is Groovy or Hydro, you want to include

<tf/LinearMath/btMatrix3x3.h>

and depend on tf, not LinearMath, which is not a package.

my apologies for the negligence. yes, i am using Groovy with Ubuntu 12.04. I suppose that the <tf linearmath="" btmatrix3x3.h=""> you mentioned is to be included in my cpp file? like this ( #include <tf linearmath="" btmatrix3x3.h=""> ) ?

I have tried to put #include <tf linearmath="" btmatrix3x3.h="">, #include <tf matrix3x3.h=""> but it shows error

apparently ROS answers mucked up my answer, those should be slashes... see the edit above

Hi, i have tried to put #include <tf linearmath="" btmatrix3x3.h=""> but it shows ##fatal error: tf/LinearMath/btMatrix3x3.h: No such file or directory## My tf package is at /opt/ros/groovy/share/tf and inside has ##cmake msg package.xml srv## Could it be possibly that there is something wrong with my tf package?

Hi, i managed to find the answer already :) it is in the package bullet. just put "#include<bullet linearmath="" btmatrix3x3.h="">" will do. Thanks for your help

For anyone coming here looking for the kinetic version (like me), it is #include <tf/LinearMath/Matrix3x3.h

For Melodic users (like me) it is "tf/LinearMath/Matrix3x3.h". Make sure to include <build_depend>tf</build_depend> in your package.xml and add tf to find_package(catkin REQUIRED COMPONENTS) in your CmakeList.txt

This was the exact thing i was missing thanks, i didn't realize i was making use of the tf2 library
