# Build a ROS Package - Method A

<note important>This needs to be confirmed, but it should work…</note>

## Base method

When you need to build a separate package for ROS, instead of going throught all the steps like in the installation process, this should work

  mkdir -p temp_dir/src
  cd temp_dir/src
  # Here, put your package_folder
  cd ../
  # Maybe you can try this to resolve the dependencies, but I'm reaaaaally not sure 'bout that...
  #rosdep install --from-paths src --ignore-src --rosdistro hydro -y -r --os=debian:wheezy
  sudo catkin_make_isolated -DBUILD_BINARY_PACKAGE=ON -DCMAKE_INSTALL_PREFIX=/opt/ros/hydro -DCMAKE_INSTALL_LIBDIR=lib --install --merge --install-space /opt/ros/hydro

Aaaannd, that's it.

## Ubuntu variant

This procedure is useful for users who have installed ROS packages from the “official” repositories and want to update a package with a newer source, so it's mainly for Ubuntu users. The _difference_ is that sudo needs to source /opt/ros/hydro/setup.bash to launch catkin_make:

  sudo bash
  source /opt/ros/hydro/setup.bash
  catkin_make_isolated -DBUILD_BINARY_PACKAGE=ON -DCMAKE_INSTALL_PREFIX=/opt/ros/hydro -DCMAKE_INSTALL_LIBDIR=lib --install --merge --install-space /opt/ros/hydro
  exit

# Build a ROS Package - Method B

This one doesn't directly rely on catkin, it doesn't manage dependencies though…

  mkdir yourpackage
  git clone --branch release/hydro/@package_name@/@package_branch@ @git_repository@ @package_name@
  mkdir build
  cd build
  cmake ../@package_name@ -DSETUPTOOLS_DEB_LAYOUT=OFF -DCATKIN_BUILD_BINARY_PACKAGE=ON -DCMAKE_INSTALL_PREFIX=/opt/ros/hydro
  make
  sudo make install
  # There should be a way to checkinstall make install... not workin' yet...
