2014-01-28 17:30:31 -0500 | marked best answer | undefined reference to a static library hello, I'm having a lot of trouble with this one: (ros fuerte, ubuntu 12.04 LTS) I'm working on a C++ package that uses a C library libccv.a. When linking, I am getting this error: and more undefined references to the stuff from the library libccv.a comes with a header file ccv.h and it depends on libjpeg and libpng. here is the relevant part of the CMakeLists.txt the library is in /lib folder of my project. everything else (source and headers) is in /src. I also tried the I read some resources on rosbuild but I can't make it work. What am I doing wrong? Any help is greatly appreciated, thanks! |

2013-08-29 01:17:31 -0500 | asked a question | moveit - nearest reachable pose for arm gripper Hi, I am working with a robotic arm and I have the following question (I am completely new to moveit): I can give the gripper a Pose to go to but the problem is that the arm may not be able to get into the pose, even though it is in its range of motion. Is there some automatic way of finding the nearest pose that the arm can get into? Thanks a lot |
2013-08-28 23:40:42 -0500 | commented answer | contributing to ros I still don't quite understand the answer to 1. My node needs an external library that I have downloaded and compiled and put it in the lib directory of the package. It is also in the repo. Will it get installed when I do all the steps in the page you linked? |

2013-08-28 09:42:02 -0500 | asked a question | contributing to ros Hi, I wrote a new package for ros groovy (here) and I would like to share it with others so that they can use just apt-get to install it. However, I have some questions before I do so:

2013-08-04 12:07:46 -0500 | commented answer | Makefile to CMakeLists.txt (ROS, Eclipse) Never seen that message. Google. Note that in the find module, the NAMES should contain "environment", not "libenvironment" also pay attention to case sensitivity |
2013-08-04 10:52:26 -0500 | commented answer | Makefile to CMakeLists.txt (ROS, Eclipse) sorry, u have the figure that one by yourself... I've got work of my own, you see. |
2013-08-04 10:41:28 -0500 | commented answer | Makefile to CMakeLists.txt (ROS, Eclipse) it works for either. check this paragraph http://www.cmake.org/Wiki/CMake:How_To_Find_Libraries#Writing_find_modules |
2013-08-04 10:36:42 -0500 | commented answer | Makefile to CMakeLists.txt (ROS, Eclipse) you probably need to write your own find module. don't worry, it's not a big deal. everything is described in the help page i linked to. to sketch the outline: create FindLIBENVIRONMENT.cmake and put it in a dir in ur package inside of the file use FIND_PATH to find the dir with the library's header file add the dir path to CMAKE_MODULE_PATH |
2013-08-04 09:29:47 -0500 | edited answer | Makefile to CMakeLists.txt (ROS, Eclipse) the CMakeLists.txt is not influenced by eclipse you should be able to build the library (libenvironment.a if I see correctly) with the makefile that you have, and then use see cmake help on how to include libraries |
