Create Follow

The Follow package will depend on messages, Python, and C++ packages.

eepp@tabor:~$ cd ros_workspace

eepp@tabor:ros_workspace$ roscreate-pkg follow std_msgs rospy roscpp
Created package directory /home/eepp/ros_workspace/follow
Created include directory /home/eepp/ros_workspace/follow/include/follow
Created cpp source directory /home/eepp/ros_workspace/follow/src
Created package file /home/eepp/ros_workspace/follow/Makefile
Created package file /home/eepp/ros_workspace/follow/manifest.xml
Created package file /home/eepp/ros_workspace/follow/CMakeLists.txt
Created package file /home/eepp/ros_workspace/follow/mainpage.dox

Please edit follow/manifest.xml and mainpage.dox to finish creating your package

This will create the follow directory with make files, Doxygen template, a source directory and include directory.

epp@tabor:ros_workspace$ cd follow

eepp@tabor:follow$ ls
CMakeLists.txt  include  mainpage.dox  Makefile  manifest.xml  src

manifest.xml will contain the dependencies listed in the package create command.

Build

Entering a make from the follow directory will create the bin and build directories.

epp@tabor:follow$ make
mkdir -p bin
cd build && cmake -Wdev -DCMAKE_TOOLCHAIN_FILE=`rospack find rosbuild`/rostoolchain.cmake  ..

cd build && make 
make[1]: Entering directory `/home/eepp/ros_workspace/follow/build'

build will contain all the make infrastructure specified by CMakeLists.txt file. bin will also be created but will be empty because the src directory is empty and no source files are specified in CMakeLists.txt.
